EMERGENCY LIGHTING OPENS THE DOOR FOR SAFER BUILDINGS Leading lighting manufacturer Tamlite calls on emergency lighting to be seen as a priority in the development and maintenance of all buildings. Building safety has become the focus of many conversations throughout the industry and beyond in recent years, with recent failings being highlighted in urgent ways. What has been highlighted is the work that still needs to be done, along with the importance of everybody in the supply chain working together to make way for a safer future. The key points that Tamlite has underlined are: the legal requirements, risk assessments, lighting design, and maintenance and testing. Tamlite also wants to highlight the pivotal role electrical contractors have a to play. Due to their involvement at every stage of a project, electrical contractors are arguably amongst the best-placed to ensure building owners and managers are aware of the implications and requirements of emergency lighting. With the right checklist – such as the one Tamlite has made available on its website – contractors can become more confident in their convictions, as well as instil confidence in building owners and managers as to what their emergency lighting requirements should be. Partnering with a specialist lighting provider such as Tamlite will be beneficial and important during every building project. Emergency lighting is the sort of addition that can go under the radar whilst planning and constructing any building, sometimes seen as just a quick add on instead of an extremely important obligation.

ECA CALLS FOR A NETWORK OF ELECTRIC VEHICLE CHARGING POINTS
HOME IMPROVEMENTS WERE THE BACKBONE OF BRITISH RELATIONSHIPS LAST YEAR Over the course of the pandemic, home was very much where the heart was forced to stay, and as a result of multiple lockdowns, house renovations have steadily become Britain’s favourite pastime. Using this as an opportunity to improve their surroundings and create more internal differentiation, 43% of Brits found that their home improvement project helped them with their mental health during the pandemic. In new national research by Powered Now, 25% of Brits agreed that as a result of the pandemic, DIY and home improvements have become their favourite hobbies, with a further 37% of Brits finding that completing a home improvement with their partner made their relationship stronger. The research also highlights that Brits have spent an average of £2,011 per person on home refurbishments, with the total spent by British consumers on home improvements amounting to £110.3bn, signalling an increase in expenditure by 29.7%. Further signifying the importance of home improvements to our mental health, Brits have detailed in the research that tradespeople were the only services that they hired in periods of lockdown. With 34% of Brits agreeing to this, the desire for tradespeople was so extreme that 37% of Brits said that the builder they wanted to use was too busy to do the work that they wanted during the pandemic.
According to recently released survey figures, just over half (51%) of NHS Trusts have now installed EV Charging Infrastructure (EVCI) for their staff, patients and the wider community. The ECA has welcomed the uptake of EVCI by the Trusts as a positive move towards net zero carbon, but according to ECA’s Energy advisor, Luke Osborne, “We need a coordinated plan for EV charging to help the public sector and the UK to achieve its decarbonisation targets. Hospitals are integral to their communities, so their plans must reach out more widely to include the wider road network.” The latest data was obtained through a FOI request by power management business Eaton, issued to 173 NHS Foundation Trusts across the UK, with 142 of Trusts responding. While half (51%) of NHS Trusts already report EVCI on-site, a further 43% plan to install charging facilities on-site within the next five years. Just 6% of NHS trusts had no plans to introduce EVCI. However, when asked about the impact of EVCI on their existing electrical infrastructure, half (53%) of NHS Trusts flagged that they would need more electrical capacity, while two thirds (41%) said it may incur additional energy costs through greater peak demand. Just a quarter (24%) saw potential to create new revenue streams from new EV charging facilities. The FOI also revealed that very few NHS trusts (11%) are currently selling energy to the grid through energy storage technologies, including vehicle to grid. One fifth (23%) plan to use energy storage to start selling energy to the grid in the next five years, but two-thirds (65%) have no plans to do so. ECA, eca.co.uk

Almost three quarters of people are interested in low carbon hybrid heating – but comfort and reliability are ‘must haves’, new research shows. The results are from more than 1,000 survey responses gathered by electricity network operator, UK Power Networks, and gas network, Wales & West Utilities, as part of their HyCompact project. The trial, which runs until March 2022, is researching consumers’ attitudes and live testing low carbon hybrid heating systems in UK homes. Hybrid heating systems work by switching between gas and electricity to guarantee lowest cost and carbon emissions. The research also suggests people will only buy low carbon heating systems if they are cheaper, more reliable, or easier to install than conventional systems. It found 72% of respondents say hybrid heating systems are either moderately or very appealing. However, the most popular reasons for switching are comfort and reliability (both 96%), plus cheaper running costs and ease of use (both 94%). The vast majority (85%) said they are satisfied with their current gas system, while around four in five would only consider switching if their current boiler stops working. If a breakdown happened, just over 80% would be interested in hybrid heating if it was less disruptive than installing a new gas boiler, underlining the need for low carbon systems to improve on products already on the market.

MYENERGI CHARGES UP AT UK’S MOST SUSTAINABLE PROPERTY DEVELOPMENT
BRITISH CABLES COMPANY GAINS FRAMEWORK AGREEMENT WITH NETWORK RAIL
Springfield Meadows, a climate-positive, net zero development of 25 homes in Southmoor, Oxfordshire, is set to benefit from the installation of zappi EV chargers. The units are manufactured by myenergi. Each of the 25 homes are built to Passive house standards, achieving net zero energy and going beyond net zero carbon to become climate positive. This means that more than the total embodied carbon used to manufacture and build each house has been effectively offset. Families purchasing a property are encouraged to forego a second car and instead participate in the site’s groundbreaking electric car club. The club will provide residents with access to two fully-electric Nissan Leaf EVs, via a leasing arrangement with Gridserve, which will be charged with 100% renewable energy via the myenergi zappi units. Jordan Brompton, co-founder and CMO of myenergi, says: “We’re thrilled to be involved with the Springfield Meadows development. The site is truly visionary, forward-thinking and exactly where we, as a society, need to be headed in terms of new housing stock.”
British Cables Company (BCC) has gained a five-year framework agreement to supply a range of specialist cables to Network Rail. The agreement met Network Rail’s key objective to create an industry-leading supply chain, focused on infrastructure reliability, safety and financial efficiency. Nick Bowman, BCC’s Sales Director comments, “We are exceptionally pleased about becoming just one of three suppliers appointed to the framework, with our products supplied directly to Network Rail’s nine regional distribution centres across the UK. “The framework requires us to supply telecoms, power, signalling and fibre cables and these will be delivered to support either quick reaction maintenance jobs or longer-term projects.”

NEXANS WILL ELECTRIFY SHETLAND’S FUTURE WITH POWER CABLE CONTRACT Nexans has been awarded a multi-million Euro contract by SSE Renewables to supply 800km of underground cables that will make the vital power connections for the Viking Wind Farm. The wind farm on Shetland in the North Atlantic, 170km from the coast of Scotland, is scheduled to go online in 2024. With a peak output of 443MW, it will provide enough renewable energy for almost half a million homes and play a crucial role in helping Scotland achieve its net zero targets.
The Viking Wind Farm will comprise 103 wind turbines set around the central mainland of Shetland. The 33kV underground cables supplied by Nexans will link the wind turbine arrays together and then export the power to the main substation for feeding into the interconnector that will transfer it to the UK grid. The 650km of underground cables to be supplied by Nexans are a single core design with cross-linked polyethylene (XLPE) insulation. The conductors for the
inter-array cables will be aluminium. Copper will be used to carry the higher current for the export cables. Nexans is also supplying 150km of bare copper earth cable. The cables for the Viking Wind Farm will be manufactured at the Nexans Hellas plant in Lamia, Greece and will be supplied via Nexans UK. First deliveries are scheduled for September 2021.

FUNDING AVAILABLE FOR INDUSTRY LEVEL 3 QUALIFICATIONS The Electrotechnical Skills Partnership (TESP) is urging adults without a Level 3 qualification to take advantage of the current funding available for industry-recognised qualifications while it remains available. Under the government’s ‘Lifetime Skills Guarantee’ any adult aged 19 or over in England, who does not already have a Level 3 qualification, can receive free training from hundreds of colleges and training providers across the country. The Level 3 NVQ Diploma in Installing Electrotechnical Systems and Equipment (Buildings, Structures and the Environment), is included in the list of funded qualifications. This qualification assesses work-based performance and leads to recognition as a qualified electrician, as an alternative route to the apprenticeship or experienced worker assessment. Funding is also available for the Level 3 Advanced Technical Diploma in Electrical Installation. This is a key stepping-stone on the industry approved training routes, for those who wish to continue to develop their technical knowledge before gaining work experience. Those who complete the technical diploma must then gain work-based experience and complete the NVQ and the AM2 assessment to be recognised as a qualified electrician. Alternatively, there are many career routes in related sectors that welcome a level of electrical knowledge, including wider building services and data cabling. With both courses normally costing thousands of pounds to complete, the funding available will provide essential support to those looking to train or upskill to become a qualified electrician in line with the TESP approved training routes.

Building Mental Health, the CITB and the Lighthouse Construction Industry Charity have published a report detailing the social value of their Mental Health First Aid Instructors Programme – an initiative to train 288 construction industry dedicated mental health first aid instructors. The Social Value Report shows that for every £1 invested there has been £5.50 of social value to society. This amazing result is despite the challenges presented by the COVID-19 pandemic, which meant that the programme had to be extended by a year. The programme achieved 99% of its target for training instructors and 166% of its target for training Mental Health First Aiders (MHFA) to operate in the industry on a daily basis. Building Mental Health was launched by a working group of construction industry leaders and experts in 2018 in response to findings published the previous year in the ‘Thriving at Work’, Stevenson/Farmer review of mental health and employers. Commissioned by the Government, the report looked into how employers could provide better support to employees, including those with poor mental health or wellbeing, to remain in and thrive at work. The Thriving at Work review identified not only the immediate human cost of poor mental health at work, but also the knock-on impacts for society and the economy. It cited that employers are losing billions of pounds because employees are less productive, less effective, or off sick. In construction alone, stress, anxiety and depression accounts for a fifth of all work-related illness.

COVER STORY
ENSURING EMERGENCY LIGHTING IS AT THE TOP OF THE PRIORITY LIST When it comes to building safety and emergency lighting, electrical contractors have a pivotal role to play, writes Tamlite Technical Manager, Stephen Biggs.
O
ver the last few years, the safety of buildings has reached an ever-higher profile in the public consciousness. Dame Judith Hackitt’s independent review of building regulations in the aftermath of the 2017 Grenfell Tower tragedy concluded that major reform was needed. Many of her recommendations regarding the delivery of a more robust regulatory system were reflected in the Government’s draft Building Safety Bill, which easily represents the most sweeping change to building safety in the last 40 years. But building safety was once again put under the spotlight earlier this year following a fire at New Providence Wharf in London. In releasing London Fire Brigade’s initial findings, Deputy Commissioner Richard Mills said: “Despite our response to this fire and drawing on the many lessons learned from the Grenfell Tower fire, in many cases we are sadly still not seeing a culture change in all those responsible for fire safety in high rise buildings. The New Providence Wharf fire needs to be an urgent wake-up call to all building owners and managers. Look at the fire safety solutions inside your building and take action if they are not performing correctly. It is too late to wait for a fire to see if they work.”
Building a safer future It once again highlights the work that needs to be done, and highlights the importance of everybody in the supply chain working together to make way for a safer future. Given the essential role emergency lighting plays in providing vital time for the safe passage of occupants out of the building in the event of a fire, it would be easy to assume that it is a de facto priority
Building safety was put under the spotlight again earlier this year

in the development and maintenance of all buildings. Unfortunately, Tamlite’s experience indicates that, all too frequently, it is still an issue that is being tackled in the later stages of a project, and sometimes with inadequate knowledge of the technical and legal requirements. Due to their involvement at every stage of a project, electrical contractors are arguably amongst the best-placed to ensure building owners and managers are aware of the implications and requirements of emergency lighting, with Tamlite’s check-list – available via the company’s website – helping to ensure this vital building safety system is fit for purpose. Legal requirements: Now required to be installed and tested in line with British Standard BS 5266:1 2016, emergency lighting should provide adequate lighting levels and directional indication in the event of a mains failure. Tamlite often explains to its end user customers that contractors are arguably the best-placed ‘cog in the wheel’ to provide the specialist insight they need to ensure regulatory compliance. It is also the contractors who can best convey the benefits of investing in high-quality and durable systems to clients. Tamlite does provide assistance to contractors, with supporting items such as its emergency lighting checklist, and can always liaise in order to find the correct solution. Risk assessment: One of the most common mistakes made with emergency lighting includes missing risk assessments, yet it is a legal requirement to have one. Taking accountability throughout the lifecycle of a building will play a key role in restoring confidence in the design, construction, maintenance, and operation of premises, so it is important to ensure that risk assessments have been carried out and that the systems in place are fit for purpose. Lighting design: Emergency lighting products must conform to BS EN60598-2-22. It is important to ensure that the luminaires address a number of core issues. These include: the function of the building or room/area; the mode of operation (for example, office, commercial or residential); the extent to which users are familiar with the building, including consideration of whether it receives many short-term visitors; specific usage and how it is likely to change over time; aesthetic requirements, including compliance with listed status if applicable; and the fact that different fixture heights and distances will be required for lighting in various areas of the building.
Maintenance and testing: Another common mistake is a lack of maintenance checks and regular testing of emergency lighting systems. Like all emergency equipment, emergency lighting should be maintained and tested regularly to ensure it is in full working order, and it is a legal requirement that emergency lighting be tested in line with BS 5266:1 2016. For example, a daily visual inspection can be carried out to check the batteries are operational, whilst a monthly test must be carried out to ensure luminaires turn on in the event of a power outage. Any remedial work on failures should be carried out and recorded. Emergency lighting systems must undergo a full test on an annual basis. This test ensures that all emergency lights continue to function for a three-hour duration. The importance of emergency lighting cannot be understated. In this context, it is advisable to partner with a specialist lighting provider such as Tamlite, safe in the knowledge that this provides the most direct route to achieving an emergency infrastructure that is entirely fit for purpose. Tamlite provides an elite range of compliant emergency lighting, for multiple applications. There is no doubt that it will take some years for the public in general to feel confident about the safety of buildings. But collectively we can all play a key role in constructing a culture of responsibility, providing the way forward to a brighter, safer future.

As part of this eco-friendly project, Vaillant will be supplying 221 of its aroTHERM plus air source heat pumps. The remaining 18 properties, which are in an apartment block, will use Vaillant’s aroTHERM split air-to-water heat
BALFOUR BEATTY SECURES £68M LONDON RETIREMENT VILLAGE CONTRACT Balfour Beatty has announced that it has been awarded a £68m contract by Audley Group to complete the new Mayfield Watford retirement village in Watford, London. Responsible for the design and construction of the new retirement village, Balfour Beatty will lead the completion of 255 one and two bed apartments, alongside communal facilities including a health club, swimming pool, restaurant and a multi-purpose village hall with surrounding green spaces and parking. To support the delivery of its sustainability strategy ‘Building New Futures’, Balfour Beatty will deploy safe and sustainable outcomes throughout the project lifecycle, including the offsite manufacture of the 180 apartment balconies, reducing the working at height risk as well as improving overall project efficiency. Kevin Hudson, Construction Director, Audley Group commented: “The demand for our retirement villages remains at an all-time high, so we are pleased to be able to continue our work with Balfour Beatty. We know, through our long-term partnership, how the team works to deliver to our high standards. Across the UK there continues to be a chronic lack of quality retirement housing provision and we are accelerating our growth plans to help meet this demand. Working with quality construction partners like Balfour Beatty helps us redress this balance.” Following the successful delivery of the pre-construction services works during the COVID-19 pandemic, early works are now progressing at pace with main construction works expected to complete in 2023. At construction peak, the project will employ a team of 300. Balfour Beatty, balfourbeatty.com
pump. Here, properties located on the ground floor have had heat pump units installed on the ground, while the remainder have been installed on the roof of the apartment block. The aroTHERM plus and aroTHERM split heat pumps offer an ErP rating of A+++ and A++ respectively and are Quiet Mark accredited, meaning they were the ideal solution for the eco-friendly Oakfield project.
Working closely with Igloo and the project design consultant, CBS consultants, Vaillant has been involved in the project to ensure the heating systems selected were able to run as energy efficiently as possible both now and into the future. Vaillant, vaillant.co.uk
FIVE-FIGURE PROJECT COMPLETED AT LUXURY YORKSHIRE HOTEL LED lighting manufacturer, CFE Lighting, has worked with electrical engineers from NEC Services to deliver a five-figure project at the first major new-build hotel development between York and the coast for over 20 years. The company designed and manufactured 55 exterior lighting bollards, with these supplied to the luxury Sandburn Hall Hotel through wholesaler YESSS Electrical and installed by NEC Services. The bollards are fitted with low energy, high lumen LEDs to provide wayfinding and emergency lighting along the main walkways which run around the front and back of the 40 bedroom luxury hotel. Commenting on the project, Amanda Speight, national business development manager at CFE Lighting, says: “We’re delighted to have been able to support the development of what will be an incredible destination hotel for the region. “The project enabled us to showcase the full breadth of our capabilities, from visiting the site to assess the requirements through to designing and manufacturing the bollards, using the very best components, at our production facility in Barrowford.” Hotel director James Hogg says: “Everything about the design and build of this hotel is quality and that extends to the smaller details such as the exterior lighting bollards, with CFE Lighting creating a bespoke, British-made product that perfectly meets our needs.” CFE Lighting, cfe-lighting.co.uk
CONCENTRIC RECEIVES ELECTRIC COOLANT PUMP DEVELOPMENT CONTRACT Concentric has received a new development contract to supply electric coolant pumps for a fuel cell electric vehicle (FCEV). The customer, a global truck and bus OEM, will use the Concentric’s e-pumps for cooling the FCEVs on its new flagship bus application. Buses for city and regional transport are the early adopters of FCEV-technology, with California now operating fuel cell buses for several years. The FCEV buses have a major advantage over their competition (diesel buses) because they produce zero CO2 emissions. This is particularly important in already heavily polluted, densely populated cities. When hydrogen is produced from clean, renewable energy sources, the fuel cell buses could make a significant contribution toward cleaner air in major cities around the world. Cooling FCEVs requires the use of special coolants, which are aggressive to many metals. Concentric’s engineers have developed the e-pump to be able to pump these special fluids without reducing the durability of the product or service life. David Woolley, President and CEO of Concentric AB comments: “This new agreement is another milestone in the development of Concentric’s e-pumps, as we strive for Technology + Innovation = Sustainability. We already supply e-pumps to many global OEMs for their hybrid and battery electric vehicles, and this important contract ensures we continue to support our customer’s needs as they design the zero emission vehicles of the future.” Concentric, concentricab.com

CONTRACT NEWS CITY OF SHEFFIELD TO PROTECT AIR QUALITY WITH ABB ELECTRIC VEHICLE CHARGERS ABB’s rapid electric vehicle (EV) charging points are helping Sheffield City Council to promote ultra-low emission transport as part of a new Clean Air Zone. Specialist energy contract company, Franklin Energy, is delivering the infrastructure as part of a £1.2m project to deploy 27 charging points across 11 sites in the city centre. It selected ABB’s Terra 54 technology thanks to an excellent track record of reliability. The new infrastructure will incentivise drivers to switch from diesel or petrol to electric vehicles, which will cut levels of nitrogen dioxide and particulates. The Clean Air Zone will focus on buses, light and heavy goods vehicles and taxis. Together, these represent around 20% of traffic but are responsible for half of air pollution. Fifteen of the 27 chargers have contactless payment terminals supported by the ABB Ability Connected Services. The remaining 12 chargers are dedicated for Sheffield’s licensed taxis and have been set up to provide dedicated access to taxi drivers who have pre-registered with an app set up by Franklin Energy. The Terra 54 chargers provide power rated at 50kW, which can add more than 100km of range in as little as 25 minutes. However, ABB has supplied them with an additional 43kW AC outlet, making them compatible with plug-in hybrid electric vehicles (PHEVs). ABB, abb.com
CUMBRIA ‘LED-ING’ THE WAY Work is nearing completion on Cumbria County Council’s exciting street light replacement and improvement programme. The County Council has invested £12.9m over the past seven years in this major countywide project to replace over 45,000 street lights with more efficient and cost effective LED technology. The programme has enabled the Council to reduce its annual lighting energy bill by over £1 million, reduce annual energy consumption by 60% and save more than 9,000 tonnes of carbon emissions each year. As part of the LED replacement programme, the Council believes it will be the first local authority in the UK to use a newly-developed and adaptive LED street lantern which is Dark Sky friendly. The new LED lanterns are manufactured by Thorn Lighting and use its innovative NightTune LED technology. The lanterns emit a blend of white and amber light which can be automatically adjusted to suit the time of night and level of traffic on the road. Visibility for drivers and pedestrians is not affected by the blended light colour and the scheme is fully compliant with the required safety standards for street lighting. The luminaires, deliver light focused at ground level, preventing light pollution up into the night sky with no visibility of the LED, reducing any potential for glare. The County Council will be piloting these NightTune LED street lights at five locations in Alston, Warcop, Dent, Glenridding and Ambleside, where lighting was due to be upgraded and/or is situated in a sensitive location. Each site has been selected to cover a diversity of communities and landscape settings, in areas bidding for Dark Skies landscape status nationally – the Lake District and Yorkshire Dales national parks and North Pennines AONB. Thorn Lighting, thornlighting.com
INNOVATIVE NEW CHARGING HUB OPENS IN BICESTER A new electric vehicle (EV) charging hub has opened in the heart of Bicester, at Cherwell District Council’s Cattle Market car park. The £5.2m Park and Charge Oxfordshire programme is among the first of its kind in the UK and is being delivered by a consortium of local partners, including Oxfordshire County Council and Cherwell District Council. The Bicester site is the first of 24 council-owned car parks to have an EV charging hub installed this year under the scheme. Motorists can park for free overnight and charge up using one of the 12 new ‘fast’ 7-22kw EV charging points, which will also provide much-needed battery top-ups to commuters and visitors during the daytime. Supporting the creation of green infrastructure, using low carbon, energy positive technology is a core principle of the Bicester Garden Town project, with Bicester firm Zeta developing a state-of-the-art charger for the scheme. Zeta is leading the Park and Charge project and will also be running the EV charging service on behalf of the councils under the trading name EZ-Charge. Built with ease of use and reliability in mind, the chargers can be operated by contactless payment, making it simple for EV drivers to ‘tap and go’, with no membership required.
NEW COMMUNITY HUB TO COMPLETE NORTH EDINBURGH REGENERATION Detailed plans have been submitted for a new multi-use community hub at MacMillan Square, as part of the wider regeneration of North Edinburgh. The state-of-the-art building will accommodate an early years centre for 185 children, a new library and will provide additional space for North Edinburgh Arts and will ensure that it continues to be at the centre of a creative, connected and inspired community. Complementing the Council’s new library, early years centre and affordable housing, the new hub will see arts and learning brought together under one roof in a striking new building offering the community in North Edinburgh an extensive range of services. This will include new enterprise, workshop, learning and creative studio space, alongside an expanded café, youth area and shared atrium. Allowing for further design and procurement, construction is expected to start in early 2022 to complete mid-2023. Prior to this, enabling works will be carried out onsite including the demolition of the existing library. The community hub will offer young people a place to develop skills, confidence and self-esteem, a safe and inspiring place for local families and children, and a place where older people will feel part of a connected and supportive community. This accessible, welcoming and much needed community space uses environment-friendly build and innovative design techniques. The re-developed and extended venue reflects current community aspirations, whilst being flexible enough to respond to future changes in demand. City of Edinburgh Council, edinburgh.gov.uk

SPACE SAVING SOLUTIONS FOR PLANT ROOM DESIGN The most common challenges when it comes to plant room design and the installation of equipment are size and location, says Jason Gibson, Electrical Manager at Seahorse Electrical and Maintenance Services.

a window rather than a door, or we may need to widen a doorway then return it to its original state. We also work with manufacturers where we know we can strip the kit down into smaller units and rebuild them once in situ. It’s about being flexible to the clients’ needs and being able to come up with workable solutions. A further challenge is that clients’ requirements will frequently alter and become refined during the project. At the outset, it can be that they are not 100% sure about what they need – our role is to advise them about the best solutions available to protect the power to their building, given their particular circumstances. We might suggest the installation of a further change over switch, so there is only one shut down rather than three when it comes to commissioning the system, which means less downtime for the client. Or it may be that the generator simply won’t fit in the same space. If so, it could be located in an adjacent lobby or sometimes additional building work is required. Roof canopies are a good option here, and we can recommend and arrange for the install of a planned crane lift of a Glass Reinforced Plastic (GRP) building in these cases. We also manage any strengthening of floors where necessary. The majority of our change overs (95%) are completed out of hours – at the weekends or overnight. Again, this is to minimise disruption. Being flexible and having the ability to supply the best option is part and parcel of what we do. We’ve been working with CENTIEL for around three years, but I’ve worked with Louis McGarry, Sales and Marketing Director of CENTIEL for well over a decade. We supply CENTIEL’s leading modular UPS CumulusPower, known for its industry leading levels of availability (uptime) and flexible, scalable configuration. The modular UPS is a high-quality, robust system that is very compact, fitting into footprints where standalone systems simply cannot! The racks can house five small UPS modules or just two, with the option to add more modules at a later date, providing a scalable solution as power protection requirements grow. CENTIEL’s UPS also has a top or bottom cable entry option, which helps us come up with the most optimal cable routes to avoid clashes with any other services. The whole system fits with our need to be flexible and provide the highest levels of power protection for our clients, even when working in challenging environments.
e work with clients across a range of industries including medical facilities, financial institutions, event venues and data centres to design and build plant rooms that protect the power to critical loads. Our services also include the supply and maintenance of mechanical and electrical equipment that makes up the plant room infrastructure. All too often clients have limited space. Finding ourselves working in areas as small as 2m x 2m is certainly not unusual! To compound the issue, often, all the equipment from switchgear to UPS, to batteries, cabling and generators, all need to be fitted into a small room, located in the deepest, darkest confines of a third basement level. In these cases, access can also be a major issue. Sometimes this is due to the route to the plant room or the need to fit through small spaces in order to get there. Trying to squeeze a 900mm x 800mm piece of equipment through a small hatch, while minimising disruption to the client at the same time, requires ingenuity and planning! Comprehensive site surveys are key to solving such challenges. It may be that we find a better route around the building to deliver the equipment to its final location. This could involve delivering kit through

The team at CENTIEL are also problem solvers. They are hands on, on-site and are always prepared to work hard to ensure the installation is completed with minimal disruption to the client. Their expertise and our excellent working relationship means, working together, we can always get the job done to a high standard. Whatever the challenge, we believe there is always a workable solution. Partnering with leading manufacturers such as CENTIEL means we can ensure our clients’ critical power is protected and the project runs as smoothly as possible whatever the size of the plant room!

ELECTROMAGNETIC INTERFERENCE: DETECTING THE UNDETECTABLE QinetiQ looks at how electromagnetic interference can affect an electrical installation.
I
n 2020, pilots flying in and out of Glasgow airport reported loss of communication with air traffic control between 6,000 and 10,000 feet. Communications regulator Ofcom launched an investigation to locate the source of the interference, which it described as “like looking for a needle in a haystack”. Eventually, the interference was traced to a single household directly under the flight path. The homeowner had recently installed four vintage-style lightbulbs, found to emit electromagnetic noise affecting the frequencies used by air traffic control. The bulbs were removed without incident, but
it’s easy to imagine how events could have played out very differently. This isn’t an isolated example. In September 2020, an old television was found to be knocking out wireless internet across the Welsh village of Aberhosan; and in 2017, residents in a Northern Irish street were prevented from locking or unlocking their car doors due to a faulty wireless doorbell blocking their electronic key fobs. As more technologies operate wirelessly, the electromagnetic spectrum becomes increasingly congested, demanding greater care when performing installations to avoid introducing electromagnetic interference (EMI).

KEY ISSUE Your installation as a source of EMI
A fictional (but plausible) scenario
When EMI disrupts your installation
All electrical devices produce electromagnetic signals, which can result in EMI that radiates through fields in the air, or is conducted along cables. Installations that don’t address electromagnetic compatibility – through techniques such as grounding, bonding, shielding, routing and segregation – will ‘collect’ EMI and carry it to sensitive electronic modules. They will also radiate EMI, which can affect nearby electronic systems. As discussed, the source of EMI may be difficult to pinpoint. A client may link a failure in their systems with work you complete for them – such as wireless internet blackouts in an office following the installation of new lighting. The ability to quickly and correctly attribute the interference to its true source could save countless hours of investigation. If the lighting is indeed to blame, the fault can be promptly identified and rectified. But the interference could equally be caused by the microwave oven in the staff kitchen – in which case you must be able to prove that your work is not the source of the interference. These principles are even more relevant in high-risk and high-security environments, like airports, hospitals, financial institutions and critical infrastructure. Here, lives and livelihoods could be at stake.
A newly commissioned Forex trading platform enters use. However, in its brand new data centre, servers begin failing in an apparently random pattern, at unpredictable times. The owner suspects a faulty electrical installation, bringing the installer in to carry out remedial works at the installer’s cost. After a total power and data cabling replacement, faults persist. Earth loops and earth leakage issues are then suspected, or even a cyber attack; but no cause is identified. Trading slows, share prices fall, and contractual disputes arise as businesses look for someone to blame. Unexpectedly, the source of the interference is a collection of thermostats mounted in the main service corridor, running alongside the data centre. This installation introduced several minor breaches in the Faraday shield built into the data centre’s wall. When a thermostat opens its contacts, minor arcing occurs. The EMI caused by these arcs passes into the shielded area of the data centre hall and is enhanced by the shielding. The transient disturbance causes servers to ‘latch’, requiring a manual reset of each server. If an EMI detection system had been installed in the data centre, the first switching cycles on the new thermostats would have triggered alerts. Proximity data from the EMI detectors would narrow the search to the service area, enabling discovery of the problematic thermostats within hours. These could then be removed and replaced, with no lasting damage.
When working on an installation, it’s not just the effect of your work on nearby systems that you must consider, but the effect those systems may have on your work. If assigned to an installation in Aberhosan in the summer of 2020, you could have been driven to despair trying to figure out why wireless systems kept failing – until the ancient television was finally discovered.
GROW YOUR BUSINESS
ONGOING REVENUE
Electromagnetic awareness Awareness of the local electromagnetic environment is an increasingly vital part of planning, installing, troubleshooting and maintaining electrical equipment. The ability to attribute EMI to its source – whether your activity, that of a contractor, or an unrelated third party – could keep rectification costs to a minimum, prevent project delays, and even protect against legal action in the event of a serious incident. Detecting transient EMI is notoriously difficult – but not impossible. With EMI detection in place, organisations are equipped to attribute or eliminate EMI as the cause of issues – reducing the time and resources needed to restore systems. As always, it’s better for everyone to get the job done right first time. QinetiQ, qinetiq.com

CIRCUIT PROTECTION & SWITCHGEAR
ELUCIAN — THE BEST PROTECTION With Amendment 2 of the 18th Edition Wiring Regulations due for publication in March 2022, Darren Staniforth, Head of Technical Engagement with Scolmore Group, looks at some of the key potential changes affecting circuit protection and how the company has future-proofed its newly launched Elucian consumer unit range to satisfy the anticipated changes.
T
he rationale for Amendment 2 is similar to that behind the original 18th Edition. Given the way our industry operates, the roles electrical contractors serve, and the increasing speed of technological change, the regulations must reflect these changes to ensure installations are safe, efficient, useful, and able to meet evolving standards.
The key potential changes: Mandating of AFDDs on circuits with a rated current not exceeding 32A
become mandated on a number of final circuits. Other countries mandated the use of AFDDs, in line with Harmonised Documents, many years before JPEL/64 (the committee responsible for the development of BS 7671) decided to take another look at the requirement for them to be installed. This was mainly down to different methods of construction on building sites, along with the belief that our electrical systems are more robust in the UK. AFDDs offer protection against a single series fault within one single conductor. Many of the other devices mentioned in this article require a fault to interact with another conductor, or to Earth via a known or unknown path. These are commonly known as parallel faults. AFDDs monitor
a number of characteristics within the final circuit at the same time, using a microprocessor. It’s true to say that most of the electrical items we use on a day-to-day basis have arcs within them when switching occurs. The signatures of many electrical devices and appliances have been added to the electronic chip. This allows the device to differentiate between a normally occurring arc and one that could lead to a potential fire hazard. The device is constantly monitoring the final circuit in question, and therefore needs an ultra-low amount of energy to do its job. Scolmore continues to invest in the Elucian consumer unit range to make sure installers can meet the requirements of the proposed regulation updates, and a range of AFDDs is in development.

Arc Fault Detection Devices aren’t new! They have been mentioned in BS 7671 for a number of years. The current version of the Wiring Regulations suggests that they are recommended for a small number of installations.

Clarification on the use of RCCBs and RCBOs
Currently the wiring regulations recognises four main types of RCD:
This is an area which has been causing confusion for many contractors, and Scolmore wants to offer some clarity to help them make the right choices when it comes to selecting products and solutions for the projects they are working on. Residual Current Device (RCD) is a term widely used in the electrical industry. In fact, the general definition can be broken down to a specific device type. All of them use the ability to monitor the residual current that occurs when a leakage to Earth takes place. However, they also have other characteristics that the installer needs to consider – for instance, Residual Current Circuit-Breaker with Overcurrent protection (RCBO). These one or two module devices also have overcurrent protection built into the unit. This device not only offers overcurrent protection to the final circuit, but to the device itself. The other widely used RCD is the Residual Current Circuit-Breaker without Overcurrent protection (RCCB). These are mounted within consumer units such as the split load boards commonly installed across the UK. BS 7671 18th Edition requires installers to consider the current rating of the RCCB when carrying out a new installation or, when adding to or altering an existing installation. If the current rating of the RCCB risks being exceeded due to the total current rating downstream of the device, the installer is required to take action to restrict the overload risk. The installer has a few options at this point:
AC for use with alternating sinusoidal currents A for use with alternating sinusoidal currents and where pulsating direct current is present up to a maximum of 6mA F for use as Type A above and where other DC characteristics are present B for use as Type F above and where the frequency has been altered The document for public comment on the proposed changes to the 18th Edition suggests a move away from AC devices on general installations. The proposal sees Type A devices referred to as suitable protective devices going forward. As many installations now have a number of electronic devices that naturally produce DC, Scolmore believes this change to be good. Therefore, the company has taken the decision to only provide Type A RCBOs and RCCBs in the Elucian range. This is to eliminate the need for the contractor to have to decide which device is suitable for a customer. The merits of a Type A device make it a natural selection for today’s installations. Any DC present in the install can have a detrimental impact on the effectiveness of the standard AC type RCD. Where the DC has the ability to affect the RCD, this is known as DC blinding. This method was previously used by some test instrument manufacturers to allow the measurement of Zs when an RCD was in circuit. Selectivity of RCDs is also a vital consideration if the contractor is going to install a number of RCDs in series with each other. The different types of RCDs available must be deliberated by the installer before the installation is carried out. By selecting an RCD type which is unable to handle DC upstream, the installer could compromise the safety of the users. A Type A RCD must only be installed downstream of a device equal to, or higher than, its own classification type.
• Limit the total amount of current downstream to a suitable value so the overload condition is not possible. • Ensure that the protective device at the origin of the installation (upstream) is of a sufficient rating to offer protection to the RCCB. To do this it would need to be of an equivalent rating or lower than that stated on the RCCB. This requirement is necessary because the standard BS EN 61008 does not allow for any overcurrent tolerance of the device. If the installer decides that option one is their best and easiest option, the use of diversity is limited in this application. The Regulations confirm “diversity must not be the sole means of confirmation”. The Regulations also go on to state that the installer can consult the manufacturer for their specific requirements when installing these types of devices. Scolmore has taken the step to supply 80A RCCB devices in all Elucian consumer units, in an effort to take away some of the worry contractors have when selecting consumer units and the devices within.

SPD requirements The proposal is to re-write the wording in section 443, Transient overvoltages due to the effects of indirect lightning strikes or transient voltages from man-made events, to make this element easier to read. Surge Protection Devices (SPDs) were introduced into BS 7671 around 10 years ago and they were originally thought to be required only when an installation had a lightning protection system. Overvoltage protection is currently a major part of the Wiring Regulations. Contractors are required to offer protection from overvoltage if it is believed that a consequence of the overvoltage could cause danger to human life, loss of data from banking institutions, damage to cultural and heritage installations or where there is a large number of individuals. Any installation outside of those definitions is required to have a risk assessment completed to determine if SPDs are required. If the risk assessment calculation is not completed, then the default position is to install SPDs. However, for single dwelling units the financial implications of these additional devices can be discussed with the client. If it is believed that the additional cost of the SPD outweighs the cost of the installation and the equipment within, then the contractor can make the choice not to install an SPD. The reduction in the cost of SPDs has now made it a viable option for installers to offer to all of their clients. The introduction of the 18th Edition of BS 7671 saw a lot of attention on the overcurrent rating of these devices. This led to many manufactures offering the SPD device in conjunction with a dedicated MCB. Scolmore has chosen to ensure that the rating of the SPD offered by Elucian is sufficient to rely on the overcurrent protection offered by the main fuse to the installation. This allows for more outgoing ways for the contractor to use in the installation of their final circuit. Scolmore Group, scolmore.com

ALL POWER TO THE GREAT OUTDOORS! With outside spaces needing to be more versatile than ever before, Hamilton’s Sales and Marketing Director, Gavin Williams, discusses how outdoor power solutions can give functionality a much-needed boost.
Getting power into an outside space can make multi-functional gardens even more practical and versatile
Bringing power safely outdoors Power can be delivered to a shed, garden office, or wherever it’s needed with Hamilton’s Elemento waterproof wiring accessories. IP66 certified RCD units ensure safe operation of outdoor equipment, such as hedge trimmers, lawnmowers and outdoor heaters, or an easy-access power solution while working from an outdoor table. To safely power lighting, entrance gates and garage doors – amongst other electrical circuits – the Elemento range features 20AX Retractive and Double Pole Switches. The Retractive Switch automatically sits in the OFF position. Pressing and holding the switch ON restores power to the circuit, which is indicated by a red neon power light.
The Elemento range is easy to install with convenient white-on-black terminal markings and only requires one size of screwdriver for installation. The solutions are IP66 rated with an easy-to-open latch and scientifically-formulated gel seal that ensures integrity and protection from water, dust and small particles. The casings are contemporary in design but robust and impact resistant, and can also withstand hot and cold extremes without discolouring, fading or cracking, making them perfect for the temperamental British weather! Moreover, they come with a 10-year guarantee for peace of mind.
Take control of the garden! Once power to the garden has been established, Hamilton’s IP56-rated Air Wireless 4-Channel Switching system enables remote control of different outdoor electrical features, such as garden lighting, electric gates, and pumps for decorative water features. Each channel has a maximum loading of 1.25kW, with a total load capacity of 4kW, i.e. if channels one, two and three are fully loaded making 3.75kW, you still have 0.25kW on channel four. Alternatively, you could load up all four channels with 1kW each. And with the efficiency of modern LED lighting, 4kW will be more than adequate for most projects. For control, each unit comes with a battery-powered wireless transmitter wall plate that can be mounted indoors or inside a garden office. Alternatively, a convenient hand-held key fob can be used. Each enables on/off circuit control up to 250m. An additional programmable feature is the ‘Timed’ mode that powers a circuit for up to four minutes – useful to ensure pathways are well lit for those going to and from garden office spaces when burning the midnight oil. Together, Hamilton’s Elemento outdoor wiring accessories and Hamilton Air Wireless Switching help bring a powerful boost in functionality to the garden, making it more comfortable and convenient to use all year round.
Hamilton Air sheds light in Swalcliffe Banbury-based electrical contractor Garrett Electrical Services has equipped the grounds of a country house in Oxfordshire with Hamilton Litestat’s wireless outdoor electrical control solution, Hamilton Air. Located in Swalcliffe, close to the famous Tithe Barn and just six miles from Banbury, the property’s owner sought a solution to illuminate key features in newly landscaped gardens during dusky and dark evenings. Liam Garrett, Director at Garrett Electrical Services, selected Hamilton’s Air Wireless Switching system, which enables remote control of outdoor electrical features, such as garden lighting, electric gates, and pumps for decorative water features. The company has used the solution on several projects and has found it to be a highly adaptable and reliable system for outdoor control. In the Swalcliffe property, the IP56-rated Hamilton Air Wireless Switching system was installed in an outbuilding, with a battery-powered wireless control wall plate fitted within the country house. Supporting four channels, with a maximum load of 1.25kW and a total load capacity of 4kW, the channels can be controlled by the remote switch plate or a button key fob from a distance of up to 250m. Additionally, ‘Timed’ mode delivers power to a circuit for up to four minutes, which is useful for lighting pathways. Garrett Electrical’s Engineer, James Mendham, enabled the Hamilton Air Wireless Switching solution to control a circuit featuring eight solid copper spike lights; six of these light planted borders, while a further two illuminate fencing. A second circuit controls an in-ground walk-over light that shines on and makes a feature of a stunning cherry tree. The two remaining channels have been left open to support electrical requirements for a swimming pool and water feature.

arden spaces have never worked harder than in the past year. As a place traditionally used for relaxation, gardens have become a lifeline for keeping us connected to nature and providing valuable extra space while we’ve spent so much time at home. Gardens have welcomed family and friends for socially-distanced meet-ups and been a playground while schools have been closed. If space is tight indoors, they’ve become an extension of the home office, too. Whether that means working at an outdoor table in warm weather, repurposing a shed, or even building a bespoke office. Pubs and restaurants are accommodating more alfresco drinking and dining customers – an essential lifeline for the hospitality industry to generate a much-needed revenue stream. Getting power into this outside space can make multi-functional gardens even more practical and versatile. To support, Hamilton provides a total power solution with its Elemento weatherproof accessories and Hamilton Air Wireless Switching, which can help make greater use of outside space this spring, summer and beyond.

SUSTAINABLE SWITCHGEAR: HOW MODERNISATION STRATEGY CAN DRIVE YOUR BUSINESS TO NEW HEIGHTS Any industrial organisation caught napping when it comes to technology modernisation will quickly find themselves playing catch-up. The acceleration in technological advancement in switchgear technology has been exponential. However, the modernisation of switchgear is about much more than simply the like-for-like replacement of the installed base of switchgear. David Hall, VP Power Systems at Schneider Electric explains.
How modernising switchgear impacts on sustainability bottom line Replacing outdated switchgear should be a task achieved with sustainability at its core
As greater emphasis is placed on the need to act on climate change, companies everywhere are implementing new technologies to become more sustainable. Electricity production currently relies on the burning of fossil fuels and subsequent emission of CO2 into the atmosphere. Still, other harmful gases at play within the electrical industry need to be considered when initiating switchgear modernisation. Sulphur Hexafluoride (SF6) is the most potent and harmful greenhouse gas in the world. It is an odourless, non-toxic, and highly stable gas used in various industrial and scientific applications. Nearly 80% of all SF6 is used in gas-insulated switchgear, and its phasing out is crucial
to decarbonisation and international greenhouse gas reduction efforts. It is becoming increasingly more critical to replace SF6. More electricity production and decentralised power sources such as solar and wind and more fast charging points for electric vehicles will mean adding more medium voltage switchgear to the grid to be safely insulated. Some countries are already moving to ban SF6 applications; EU regulations on phasing out SF6 are expected by the end of this year. The good news is that the technology to decarbonise the grid and reduce the risk of more potent gas being released into the atmosphere already exists. Over the past 10 years, for example, Schneider Electric has developed a way to replace SF6 with pressurised air. The company’s sustainability approach to switchgear modernisation rests on three critical initiatives: • A ‘connected’ asset for greater reliability and safety: The technology available now allows for data driven asset management. Moving to a predicative maintenance strategy not only allows for a reduction in unplanned outages, but also increases the life expectancy of the asset. Schneider Electric has a wide range of thermal, environmental and partial discharge monitoring sensors that can be fitted throughout the MV/LV system. The continuous monitoring of the asset allows for advanced machine learning algorithms to predict specific failures of equipment, give actionable insights and reduce OPEX costs. • An emphasis on retrofit as opposed to replacement of existing gear: In a switchgear retrofit approach, Schneider Electric does all it can to preserve the base material of the existing switchgear (i.e., metal panels, cubicles, wiring) while adding in green compliant, SF6-free replacement components. The past model of ‘rip and replace’ has become obsolete in a world that counts on sustainability to maintain our planet’s collective quality of life.
• A focus on green premium replacement components: When new products are installed into existing switchgear cubicles and cabinets, Schneider Electric ensures that the new parts meet ‘Green Premium’ programme standards. This means providing detailed information regarding their regulatory compliance, material content, and environmental impact – certified through third-party labels and product certifications that supports its customers’ sustainability ambitions. They also incorporate principles of the circular economy, including durability, upgradeability, and recyclability. As a result, customers who choose to install Green Premium products reduce their CO2 footprint and optimise the total cost of ownership of their assets. Replacing old switchgear technology offers a vast opportunity for enhanced sustainability. Companies need to decrease their emissions across all GHGs; the higher their concentration in the atmosphere, the greater the risk of experiencing the most severe effects of global warming. Companies focused on modernisation to reduce GHG emissions are one step ahead of the competition. The business benefits are clear, with reduced downtime and greater operational efficiency at the fore, but the industrial and environmental benefits stand an organisation in far more excellent stead for long-term business growth.

odernisation allows for a greater competitive edge and enables an organisation’s employees to enhance operational efficiency and safety. For industrial plant power distribution, modernising switchgear can contribute a 30% cost saving from decreased production downtime and reducing equipment site work costs. On the other hand, industrial organisations running on ageing power distribution equipment place themselves at a higher risk of downtime, rising maintenance costs and reduced safety. Over time, manufacturers supplying spare parts tend to phase out supply, meaning that if an incident were to occur that required parts replacement, the repair would take longer. In addition, the scarcity of the parts in circulation means that their price boosts significantly. But alongside these crucial factors, replacing outdated switchgear should be a task achieved with sustainability at its core.

ELECTRICAL SAFETY FOR NEW HOMEOWNERS Last August, the rules on permitted developments were relaxed, allowing more types of extensions to be carried out without full planning permission. If the work can be considered as ‘material alteration’ to the property according to the Building Regulations, rewiring is likely to be needed, including upgrading the consumer unit. Ashley Clements-Smith, Senior Channel Lead from Honeywell, discusses which devices should be considered when installing new consumer units under these circumstances.
C Metalclad CP consumer unit
hanges to Permitted Development Rights were introduced last August, which meant homeowners could do more with their homes without needing to go through the full planning process. If the modifications involve major remodelling work on the property, the works will need to comply with Part P of the Building Regulations and meet BS 7671:2018 – the 18th Edition Wiring Regulations. If the amount of work involved is significant enough to be considered as ‘material modifications’ by the Building Regulations, it is likely that rewiring will be needed for part, if not all, of the property, including upgrading the consumer unit. In anticipation of the second amendment to the 18th Edition regulations which are currently under consideration, what should electrical contractors look for in a consumer unit to provide circuit protection that is futureproofed?
Mod cons
“It is worth installing products with circuit protection to help future-proof extension projects”
Over the past 50 years, the industry globally has moved away from traditional linear loads from electrical products such as incandescent lighting to power devices which have switch mode power supplies. Where the former take their power along the whole current wave form so that the load is linear, the latter take different chunks of current out of the sine wave. This distorts the waveform, which causes peaks and troughs. Newer type-A Residual Current Devices (RCDs) like those featured on Honeywell’s Metalclad CP can detect DC fault currents, whereas older type AC RCDs are less likely. Although the use of these type-A devices is not mandatory, they are now becoming increasingly specified by consultants and contractors and are recommended in the 18th Edition to provide better protection. Most modern homes have appliances such as washing machines, dishwashers and fridges, and with mod cons such as LED lighting, lighting and heating controls, and induction hobs likely to be installed as part of new extension works, type-A RCDs should be considered. Type A RCDs are mandatory for circuit protection for sites with electric vehicle charging stations.
Hidden defects
Surge protection When lightning strikes, voltage can be induced onto the local power line, causing a sudden rush of voltage entering properties. A Surge Protection Device (SPD) is designed to absorb this voltage to protect properties and their electrical equipment. It is not mandatory, but a recommendation in the 18th Edition, depending on the probability of lightning strikes in an area. SPDs are offered as an optional extra in the Honeywell Metalclad consumer unit. Although a decision on possible amendments to the 18th Edition wiring regulations will not be made until early 2022, it is worth installing products with circuit protection to help future-proof extension projects. This way, customers can be reassured that their properties have been protected to the latest industry requirements and beyond. Honeywell, hwll.co/Metalclad

An AFDD is an intelligent device which monitors the power system to detect dangerous arcs. These types of arcs could be caused by issues like problematic connections in a faulty piece of equipment, insulation defects in cables, damaged cables or loose terminal connections. Dangerous arcs generate heat and, if these go undetected, they could lead to fires in electrical equipment or the fixed wiring.
When an unsafe arc is detected, AFDDs disconnect the circuit. They are programmed to tell the difference between safe and dangerous arcs so that normal ones such as those caused by switching cycles do not trip the AFDD. Although these are not mandatory in the current 18th Edition, it has been proposed to make them so in the next amendment, to provide better protection against fires caused by arc faults in AC final circuits. AFDDs can be installed in distribution boards and consumer units. Two AFDDs can be included in the Honeywell Metalclad CP consumer unit so that households can be protected from the dangers of these electrical faults, which are often unknown until it’s too late.

o provide electricity to the high-rise towers, the consultant for the project, MCA Consulting Engineers (MCA), and M&E contractors from Box and Charnock required a solution that would deliver on performance quality in line with the rest of the development. However, it also needed to be quick to install and commission, given the demand for developments of this kind to be completed by the end of March 2021.
Connecting the blocks For the electrical installation, one of the main challenges was how to connect the two main high-rise tower blocks to the mains electricity supply. The entire development was to be supplied from the basement plant room for Block A and, as such, busbars were to be installed across an open car park between the buildings, as well as in the risers. “Given the difficulty posed by installing across the car park, we specified Zucchini MR Busbars from Legrand as a more practical option for this type of installation,” said Michael White, Production Manager at MCA. “It reduced the large number of sub-mains required for the electrical installation within the risers and across the car park, so naturally it was the most practical choice to overcome this challenge.” In this type of installation – where mains supply derives from one location – busbars can facilitate the easy addition or upgrading of circuits from a tap-off point. This means a new circuit installation would not require a sub-main to be run back to the mains source, saving time and potential disruption later on in the building’s life. Because of this more complex configuration of busbar installation, standard runs of three metres would not be sufficient and so bespoke components were required. T-shaped elements, for example, were required to connect the horizontal car park runs to the vertical riser runs in Block B, as well as shorter busbar parts to fit the development’s exact measurements. “Many projects require a bespoke element when it comes to installation, however, it can hold up proceedings if they take a while to be supplied,” said Danny Baldwin, Project Manager at Box

POWERING UP A PRESTIGIOUS HIGH-RISE DEVELOPMENT and Charnock. “A Legrand engineer came to site very promptly and took the measurements to get our equipment ordered. Despite being required during a time where the pandemic was greatly affecting supply chains, the materials arrived quickly and we were able to get them installed without any issues.”
Space considerations In any high-rise residential development, building services must occupy minimal space to afford more for apartments. As such, the selected system needed to occupy as little room as possible in the riser areas, as well as deliver on flexibility in the confined space. In the smaller Block A, the busbar centre feed unit’s positioning within the riser was not accessible within the dimensions of the space if mounted on the back wall, as designed. This meant Box and Charnock had to change the busbar position to ensure there was sufficient access to the unit. “Within the riser dimensions, fortunately the space was deep enough to house the tap-offs, and mount the solution on the left wall instead of the back as we did for the other block,” said Danny. “There was minimal disruption thanks to the flexibility the busbars provide. It was possibly even easier than the Block B, given we didn’t need to install the supplementary strutting to offset the mounting of the equipment to pass the brackets for the GRP grate floor panels.” In a further effort to maximise living space available, the plug-in distribution boards were also selected thanks to their size. Michael White explains, “The plug-in boards were a simple and space saving alternative to others available on the market. On top of this, other options would have required tap-offs and sub-main links which are tricky to install neatly with a confined space. The full solution from Legrand was a much better system, thanks to its size and integration with all of the building services areas across the development.”
Quick installation and commissioning For any contractors and consultants working on high-rise developments, ensuring electrical installations are quick and easy is key when there is pressure to complete projects. The specified busbars along with the compatible plug-in distribution boards provided Danny and his team with a quick-to-fit solution to overcome this. “Even with challenges posed by the car park installation and limited riser space, the system was simple to fit,” said Danny. “On top of this, we discovered no issues during the commissioning phase, while no equipment needed to be replaced. On a large project such as this, replacements can be time consuming and costly, particularly if other aspects need to be removed to access the services. Having a high-quality busbar and plug-in distribution board system like the Legrand solution gives peace of mind to contractors that replacements will not be required after testing.” With the London construction market booming, Paul Martin, Lead Marketing Manager for Legrand’s Power Distribution division, said, “We want to support consultants and contractors who are coming under pressure to deliver projects to satisfy growing demand in cities like London. Linton Fuels represents a project where our busbar and plug-in distribution boards can overcome challenges in the design stage as well as during construction.”

PASSIVE FIRE STOPPING: DON’T LEAVE IT TO CHANCE! Gary Parker, ECA Technical Manager looks at the importance of passive fire stopping.
P
assive fire stopping is an essential requirement in the Wiring Regulations (BS 7671:2018). It can also be integral to meeting the requirements of key legislation such as the Health and Safety at Work Act, Electricity at Work Regulations and Construction (Design and Management Regulations). Yet, many electrical contractors fall short in this aspect of electrical installation and design. Knowing the basics of passive fire stopping may sound easy, but it can be a complex topic and it demands careful consideration and effective onsite communication. Fire-stopping, or passive fire protection to use the proper term, is one of the most important aspects of any building services installation – whether it involves components such as cables or cable trays, or potentially sizeable elements such as pipes and ductwork. A building with incorrect fire stopping can be as dangerous as a building with no fire stopping at all. Put simply, various aspects of electrical installation in buildings involves locating, sharing and, in many cases, making or enlarging holes in walls or other partitions. These partitions are there for a reason – one of which is likely to be to stop the spread of fire and smoke. Whenever building services work penetrates walls, floors, or ceilings,
it is therefore vital to maintain and, if need be, reinstate the integrity, and fire rating, of the construction. This requirement also applies to cable containment systems, such as trunking, where the containment passes through a barrier, the insides of the trunking may also require passive fire protection components too. For electrotechnical professionals, knowledge of fire compartmentation is vitally important. This is the principle of subdividing a building using materials with a specific resistance to fire, to help to manage and contain fires. Usually, these subdivisions are made from walls, floors, and ceilings. Ultimately, provided building elements such as walls, floors, and ceilings can halt or even slow the spread of fire and smoke, then people have a much greater chance of safely evacuating a building in case of a fire. Any breaches in the building fabric reduce its ability to prevent the spread of fire and smoke. Therefore, where a hole is made in what is essentially a fire barrier or compartment, ‘fire stopping’ – passive fire protection – will also be required. Openings for cabling or other services in a building’s compartments can create a gateway for fire if not properly sealed. Regulations 527.2.1 – 527.2.4 of BS 7671 require that sealing of penetrations should match the fire rating of the building. However, it is important to note that some products such as expanding foam, silicone, or caulk may appear to fill the gaps, but they have no fire stopping properties. To achieve effective fire stopping, selecting the correct sealant or product is paramount. Ideally, the products used should be selected in conjunction with the manufacturer, to ensure that the installation as a whole meets all the passive fire protection requirements. Some key questions to consider when carrying out passive fire stopping work around compartment breaches may include: • How long should the fire stopping material delay a fire – 30, 60, 120 minutes? • Does the material need to bear weight, e.g. if it forms part of a floor?
• Does any electrical containment require fire stopping on the inside and the outside? • Will any services need to pass through the barrier in the future?
✓ Do: • Avoid making unnecessary or unplanned holes, gaps, or voids in compartmentation areas • Follow the correct methods for fire stopping required by manufacturers • Use materials that will sufficiently withstand fire and heat • If you have any concerns about the effectiveness of compartmentation, raise these to your supervisor or line manager • If requirements for fire stopping are not clear, the client or building owner should be notified immediately ✗ Don’t: • Create any unnecessary breaches or holes in fire compartmentation • Leave any penetrations with no fire stopping (e.g. during installation of cabling) • Deviate from the required fire stopping specifications for the task in hand • Use makeshift filling methods or materials to block holes or gaps in compartmentation Specifications for fire stopping often go into considerable detail, accommodating concepts such as the inherent natural expansion and contraction of materials in different conditions. Substrates need to be robust enough to accommodate the methods of fixing but may also need to perform under extremes of temperature and humidity. It is for these reasons that fire-stopping, in all but the simplest of cases, should be regarded as a specialist activity – best assigned to specialist service providers. Ideally, a specialist subcontractor should be involved – at the design, specification, installation, and verification stages of construction. Ultimately, we all have responsibility when it comes to fire safety. Fire safety should never be left to chance. ECA, eca.co.uk

THE RISKS OF USING ELECTRICAL EQUIPMENT OUTDOORS With the warmer weather and more people spending time in their gardens, the use of electrical equipment outdoors is increased. According to a recent survey by Technique Learning Solutions, more than 85% of the UK public use electrical equipment outdoors. While those in the electrical industry will already be familiar with the dangers this can bring, it’s important to stay aware and inform customers about them too.
M
any different types of equipment are used outdoors, all of which bring their own risks:
• Extension leads are the most common electrical item used outdoors, allowing homeowners to plug in many different items. • The majority of homeowners begin fixing up their gardens as early as April, requiring the use of tools such as trimmers and lawnmowers. Lawnmowers are the most dangerous garden tool, causing 6,500 accidents per year in the UK. • One in seven Brits have outdoor lighting – whether outdoor lights have been installed and wired up by an electrician, are battery or mains powered, they all bring risks. • Many Brits use mains powered entertainment equipment outside, such as speakers, and some may even bring their TV outdoors for an ‘outdoor cinema’ experience. It can be extremely dangerous to bring any mains powered items outdoors. • Many Brits have hot tubs, Jacuzzis, or heated pools in their gardens, and despite these usually being wired up by experts, they still bring hazards. Hot tub sales surged in the 2020 lockdown. These are just a few examples of equipment that homeowners may have or use outdoors – in warmer months, gardens often become an additional living space, with some survey respondents even claiming to use their iron outdoors in warm weather. The most common hazard which comes from electrical equipment is electric shock. One in 10 have experienced electrical shock or accidents whilst using electrical appliances outdoors. There are many ways electric shock can happen and a common cause is cutting a live wire when
using lawnmowers and other gardening equipment. Additional hazards include fires, damaged appliances, and even death in some extreme cases. Everybody knows electricity and water do not mix, yet people still risk bringing equipment outside, despite the UK weather being unpredictable. Water is a great conductor of electricity, so getting electrical equipment wet will make it live and make surroundings live too, increasing the chance of electric shock. Whilst those in the electrical industry know and understand the dangers associated with the above equipment, the general public might not realise just how many hazards are created from having electrical equipment outdoors and how easily they can happen. Its important electricians share their knowledge and expertise as it can help save lives. When it comes to powering these items, outdoor sockets are a better and safer option than trailing extension cables outside from indoor mains sockets. Outdoor sockets need a minimum rating of IP56, meaning they will stay watertight and protected, even if the garden is being jet washed. However, findings show the main way electrical items are powered is simply by plugging an extension cable into an indoor socket and bringing it outside, which brings a range of hazards due to possible overloading, weather conditions and the risk of cutting wires. It’s not likely customers will hire electricians solely to improve their outdoor electrical safety, as they often aren’t aware. When an electrician is attending a domestic job, specifically in the warmer months, it may be a good idea to ask customers how often they’re in their back garden and if they use electrical equipment outside, if they have an outside socket, and if their sockets are RCD protected. Depending on their answers, electricians could suggest ways to make sure
homeowners are keeping themselves, their family, and their home safe. Over 50% of the public don’t know what RCD protection is, and two in five people have no idea if their sockets are RCD protected. Explaining the importance of RCD protection to customers and recommending they ensure all sockets, inside and outside of their home, are RCD protected could prevent accidents, fires, and save lives. There are RCD plugs on the market which homeowners may use – whilst these do provide protection, a built-in RCD offers more protection. As well as suggesting RCD protection and outdoor sockets, if you notice any damaged cables, socket or installations whilst working in a home, it’s always worth pointing these out and advising customers to get them fixed as it can be very dangerous. There are many outdoor electrical risks during warmer months, and whilst homeowners are overall responsible for the safety of their homes, family, and selves, those who are trained to work in the electrical industry providing information, advice and recommendations can reduce risks, spread awareness and save lives.
The most common hazard which comes from electrical equipment is electric shock

HOW BUILDINGS CAN BRING PEOPLE TOGETHER SAFELY Emma Segelov, MK Electric’s EMEA Marketing Operations Manager, examines why post-pandemic concerns about indoor building health and safety remain high, why these shouldn’t be ignored, and what building owners and managers can do to make electrical touchpoints safer.
C
ompanies have a duty to protect employees and stakeholders whom they conduct business with, from anything that may cause harm arising in the workplace. Although more than 30m[1] people in the UK have been fully vaccinated against COVID-19 at the time of writing, the pandemic is not over yet. Therefore, organisations still need to employ effective mitigation practices as they bring back workers, students, shoppers and restaurant goers into their premises. So how can building owners and managers make these spaces safer, not only in the short term, but even when the pandemic ends? Minimising the spread of contaminants via electrical touchpoints is a good place to start as part of wider infrastructural improvements. One of the biggest changes that MK Electric has seen is how people’s awareness levels have increased about how being indoors impacts on infection spread. This has resulted in people considering aspects like touchpoints and adherence to safety guidelines which weren’t high priority before. In a recent study commissioned by Honeywell and carried out by Wakefield Research[2] of workers’ perceptions on the health and safety of their workplace, a staggering majority of the UK respondents (71%) do not feel completely safe working in their employer’s buildings. Half of the participants interviewed are equally
concerned with transmission of COVID-19 through touching a surface that has the virus (51%) and through the air (49%). Many buildings have changed procedures to keep occupants safer, but more permanent modifications are not being made to the buildings themselves – and their occupants have noticed. 62% of respondents in the UK believe that their building management is likely to make short-term changes in response to COVID-19, rather than long-term investments in building systems to keep them safer. With nearly one in five (22%) surveyed UK remote employees saying that they would look for a new job rather than return to a site that did not implement the necessary safety measures, it is clear that companies who don’t take the provision of safer and healthier environments seriously enough in the future, even when the current pandemic ends, could risk losing valuable staff. As part of making long-term improvements to create a healthier environment overall, consideration should be given to minimising the spread of contaminants via touchpoints, such as electrical switches and sockets. This is part of the reason why there is an increased demand for electrical products with inherent anti-bacterial and anti-viral properties, such as MK’s Logic Plus and MK Base ranges. Although it’s not always easy to justify infrastructural upgrades in the current economic environment, the choice of wiring devices available means that healthier building environments can be created, whatever the project and budget. To provide adequate protection for users against contracting an infection from frequently touched surfaces like electrical sockets and switches, products that have been tested to the latest internationally-recognised standard – ISO 22196:2011 – should be recommended. Claims made on products that have not been tested to an industry recognised standard such as ISO 22196:2011 may not be as scientifically robust.
Specifiers and installers should look for efficacy across a range of pathogens, some of which could be more relevant to the end-client’s sector. For example, MRSA can cause a serious infection and often poses a higher risk to patients in hospitals and other healthcare environments. Viruses too, can cause a wide variety of illnesses. One of the smallest known non-enveloped viruses, Phi-X174, is used as an internationally recognised standard in anti-viral testing to analyse the resistance of critical PPE and air filtration systems to blood-borne viruses. Non-enveloped viruses are much harder to kill because they carry the proteins used to infect cells in an inner layer which is less susceptible to disinfectants. This is in contrast to their enveloped counterparts which have an outer membrane. The membrane contains the proteins used by the virus to enter its victim’s cells and is sensitive to chemical and physical treatments. Because non-enveloped viruses are harder to disinfect, it is one of the reasons why protection against Phi-X174 is used as a standard for evaluating antiviral performance. As we make our way back into indoor spaces, the use of both short and long-term measures to combat the spread of pathogens will be key in instilling confidence amongst employees and other building occupants. Investing in infrastructural upgrades contributes to a healthier environment, helping to retain and attract both staff and customers coming through those doors. MK Electric, hwll.co/MKAntimicrobial

ELECTRONIC SECURITY SYSTEMS MARKET ON THE UP Neil Baldwin, Managing Director of security products supplier, ESP, looks at why now is an ideal time for the company’s CCTV range revamp.
A
ccording to the 7th edition of the Electronic Security Systems and Admission Control Market Report – UK 2021-25, the market for electronic security products and services had been growing steadily between 2015 and 2019, before a sharp contraction in 2020 caused by the COVID-19 pandemic and its impact on the construction sector and on economic activity more generally. The report describes the UK electronic security market as mature, especially in the non-residential sector, in terms of the proportion of premises that have some form of security equipment installed. This means that demand for replacement and upgrades is the key feature of the market and accounts for the majority of end-user sales.
Technology driving the market
There are a number of kit options available, including two or four camera kits
Technological developments have driven the replacement market, with heavy expenditure on R&D a key characteristic. Leading technological trends include improvements in image quality, thermal imaging, artificial intelligence (AI), deeplearning analytics for CCTV, cloud-based solutions for video management systems, and facial recognition and other biometrics for access control.
The COVID-19 pandemic has generated further development of specific applications such as management of crowd density and touchless access control. Following the downturn in 2020, the prospects for recovery in the electronic security market are good. Services are likely to be the fastest growing area of the market. The increased numbers of CCTV cameras and electronic access control hardware devices, higher image quality, and the retention of larger quantities of footage for analytic purposes, will combine to create increased data storage requirements, generating a rise in demand for cloud-based data hosting services to reduce capital expenditure on in-house servers and software.
ESP – investing to stay ahead Whilst the last 12 months have been a time of uncertainty and upheaval for many, ESP is in the fortunate position to have been able to continue to make significant investments in the business. New products, additional support services and new team members within sales, technical and customer service departments, have all been introduced as the company experiences continued growth. The latest product category to come under development is CCTV, with a revamp of the RekorHD 2MP CCTV range. Available in kit form, Rekor HD provides all the elements required to get a system up and running in one box – making it popular with installers because of the convenience, whilst offering wholesalers the advantage of ease of ordering and stocking. The only additional item required is a monitor to access the menu and system display.
Easy set up CCTV systems The systems have been designed with ease of set up as a key feature, including the option for remote monitoring via smartphone or tablet, using ESP’s specially developed ESP View app. The revamped range introduces new and improved cameras, which feature
contemporary styling and robust metal housings. The infrared capture has been increased from 20 to 30 metres and the range now includes intelligent function, with perimeter intrusion detection and line crossing detection, offering improved functionality compared with the traditional motion detection feature. The new Rekor HD kits include a stylish 4-channel DVR, pre-installed premium surveillance hard drive, cameras, camera cables, system power supply, mouse and HDMI cable. The menu is designed to be very user-friendly and is navigated via mouse control. There are a number of kit options available, including two or four camera kits, with the cameras offered in either a bullet or dome style and available in a white or grey finish. This brings a total of eight different Rekor HD CCTV kits available. The cameras can be purchased separately to extend the system if required. Before and after service support for the system is available through ESP’s highly experienced UK technical support team. As we look forward to continued recovery in the security market, the company sees the launch of the revamped RekorHD range – with its wealth of features and benefits – as ideally timed to help satisfy the growing demand from customers and contractors for a wide range of quality, value for money CCTV applications.

FIRE, SAFETY & SECURITY
THE EVOLUTION OF ELECTRICAL SAFETY STANDARDS David Cowburn, Chief Operating Officer at NAPIT, reflects on the progress made by the electrical industry to enhance electrical safety standards over the past decade.
I
t doesn’t seem all that long ago, that I was sat in front of the Communities and Local Government Select Committee answering questions about Electrical Competent Person Schemes, the impact of Part P, enforcement and consumer awareness, to assist with its inquiry in 2013-14 into ‘Building Regulations certification of domestic electrical work’. Yet looking back, a lot has changed since then, and although many of the recommendations from the inquiry were for the government, the electrical industry has taken considerable steps to make improvements to safety standards in the sector. One of the main focuses of the inquiry was the lack of public awareness around Part P of the Building Regulations, and the confusion caused by multiple electrical competent person scheme operators. The Committee called for the industry to unite and produce one consumer facing brand and register for all registered electricians to use and be listed on. It was following this recommendation that ‘Registered Competent Person Electrical’ (RCPE) was created in 2014. The single mark and register aims to raise awareness of electrical safety in the home by simplifying the task of finding and checking a competent, registered electrician. It was updated in 2020 to provide a differentiated search for those looking for an electrical company registered to carry out electrical installation work or to undertake an electrical safety report, in support of the introduction of the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. Also, to support these regulations, the industry moved to update the Electrotechnical Assessment Specification (EAS) to introduce the minimum technical competence criteria required for carrying out periodic electrical inspection and testing. The update provided a consistent standard upon which the assessment of competence is undertaken for those who wish to be registered to carry out electrical inspection and testing, creating a common approach to enhance standards. Importantly this focused on the individual carrying out the inspection and testing work, not their qualified supervisor.
The EAS is intended for use by certification and registration bodies undertaking the assessment of enterprises carrying out electrotechnical work. It sets out the minimum requirements to be met by an enterprise and the individuals working for that enterprise, in order to be recognised by a certification or registration body as technically competent to undertake the design, construction, maintenance, verification and/or inspection and testing of electrical installations. It currently serves as the minimum technical competency document upon which MHCLG authorises electrical competent person schemes to operate and sets the benchmark for the sector. Although not particularly well known, it is the key document the industry can use to enhance safety standards and create positive change. Since the Communities and Local Government Select Committee Inquiry, the EAS has been updated twice to overcome many of the issues raised. The 2015 version introduced a requirement for electrical contractors to hold an up-to-date qualification within two years of a change to the wiring regulations. This version also introduced specific risk-based requirements, clearly outlining the extent of on-site involvement needed by the responsible person throughout the duration of electrical installation work, to mitigate the risk highlighted by the inquiry of the person undertaking work in people’s homes not being adequately qualified or supervised, since enterprises are registered rather than individuals. The 2020 version of the EAS built on these changes to require registered companies to demonstrate the competence of their employed persons, including temporary, agency and sub-contracted labour. This includes the provision for the assessment of individual competence that has been the underpinning principle of the NAPIT scheme from its conception. Further to this, from September 2021, only full qualifications will be accepted for applicants to electrical competent person schemes, removing the auditable evidence route which was often criticised as allowing shortcuts for gaining entry. This demonstrates a
The committee called for the industry to unite, producing one consumer facing brand
significant step change for the industry and shows a clear commitment to continued improvement. This hasn’t neglected those with experience, as the recognised qualifications available include approaches for using such experience to achieve a suitable qualification. At the time of writing, the MHCLG is reviewing the competence criteria used within authorised schemes and the EAS will continue to evolve to accommodate these. It is, however, important to remember that there is no legal requirement for electricians to be registered with a competent person scheme, and so whilst NAPIT can, and will, continue to push for enhanced standards, the option remains for consumers to, perfectly legally, use unregistered electrical installers who are not required to meet the conditions set by the EAS. Reflecting on one of the core recommendations from the inquiry, for the government to put in place arrangements to incentivise and assist local authorities to strengthen the enforcement of Part P, NAPIT reiterates this recommendation and asks that now more than ever, enforcement needs to be addressed. Whilst there are examples of great work going on within the industry to help understand and quantify the extent of the safety risk posed by unsafe and non-compliant electrical installations in dwellings throughout the UK, through the creation of a reporting form, it is up to the government to create real change in the enforcement landscape.

FIRE, SAFETY & SECURITY
PROACTIVELY PROTECTING BUILDINGS Crisis situations happen every day in buildings around the world. At the final distribution level – where electrical systems connect to plug outlets – risks continue to impact safety, resilience, and service continuity in all kinds of buildings. The most prominent risks being fires and downtime, writes Deepak Sharad, Marketing Development and Offer Manager at Schneider Electric.
F
ires can put lives at risk, especially in high-density buildings. They can also cause significant structural destruction, costly loss of contents, and force operations to shut down for long periods of time. The European Fire Academy (EFA) estimates 25% of building fires are electrical in origin. What if facility personnel were able to identify a risk before it caused an outage or a fire? Thankfully, emerging technology is making this possible. Evolving standards and regulations have driven the improvement of electrical protection technology in recent years – particularly to protect against arc faults. In electrical systems there can be problems with installation, maintenance, aging, weakened or loose connections, accidental cable damage, or power sockets in poor condition – any of which can cause an arc to occur. If left unchecked, a vicious circle can occur, causing more arcs that eventually lead to a fire. To mitigate this risk, the arc fault detection device (AFDD) was developed, to detect arcs much smaller than a circuit breaker is capable of. The AFDD is now recognised worldwide, becoming part of many standards, including IEC 62606 since 2013, and soon under BS 7671 in the UK. AFDDs should be installed on a building’s final circuits close to loads, especially in buildings with sleeping accommodations or that propagate fire easily, and in locations with stores of combustible materials or irreplaceable goods. However, fully protecting buildings and people from risks is still increasingly challenging. Large buildings are complicated ecosystems with a higher number and variety of loads – increasing the chances of an electrical fault. The traditional approach will not suffice anymore. You can no longer wait for an overload fault to happen, because it will mean downtime, loss of revenue, and negative impact on operations and
customers. And it may also mean a risk to the safety of people. While an AFDD can arrest the immediate risk of an arc fault, technicians need a faster and more effective way to respond to the problem. Also, once a fault has occurred, it may take an unacceptable amount of time to fix. We now live in a world with unprecedented types of events, such as climate-related emergencies and pandemics. In these situations, technicians may not be available on site. Even if they are, they must diagnose the problem, then fix it. During this time, customer experience is affected, and revenues are being lost. The answer to this, is to take a more proactive approach – addressing risks before they cause problems. This requires more visibility into what is happening inside your electrical panels. You need to access all types of electrical health parameters in a more integrated way, anytime and anywhere, even when offsite. It’s now essential to be alerted if something could go wrong. This new level of visibility requires heightened connectivity. We live in an increasingly connected world. Almost every part of a building’s
Evolving standards and regulations have driven the improvement of electrical protection technology in recent years
infrastructure can now be connected, with powerful analytics that help facility teams take a more ‘digitalised’ and proactive approach to HVAC, power, and energy management. But when it comes to electrical safety, connectivity is still often treated as an option, with communication being implemented as ‘add-ons’ only when and where the need arises. This needs to change. The modern thought process should be connectivity by default. This new level of connectivity needs to go beyond basic remote monitoring and alarming traditionally offered by some electrical equipment vendors. Sending an alarm only after a fault or outage has already occurred means that facility personnel are forced into a reactive mode, having to work fast to locate and correct the issue to get all circuits back online. Limited access and limited information can make that response even slower. The newest ‘active safety system’ technology integrates multiple smart protection devices with embedded, pre-emptive diagnostics. Built-in wireless connectivity enables simple integration with a complete active safety system solution, including a single wireless gateway per cabinet with a fast link to power monitoring software. User definable thresholds enable pre-alarming on risk conditions, sending an early warning by email or SMS to the mobile devices of all appropriate team members. Smart diagnostics generate actionable messages, informing technicians of the exact type of risk condition and the precise location of the circuit, allowing technicians to respond quickly, and bring power back as fast as possible. Active safety systems will play an important role in buildings of the future. Rather than wait for regulators and standards to catch up, these new solutions should be considered as part of the specifications for greenfield, expansion, and retrofit projects now.

LED LIGHTING
FIVE LED LIGHTING MYTHS DEBUNKED The use of LED lighting has skyrocketed in the last decade, with businesses now working harder than ever before to improve their energy efficiency and help tackle climate change. But while many businesses are more informed about the numerous benefits of LED lighting, there are still several aspects of this technology that are widely misunderstood by end users, according to Steve Gardner, Managing Director, Eco UK Group.
O
ne of the main concerns raised around switching to LEDs is the price. This could be how much the initial installation will cost or if the ROI figures are as good as the lighting professionals claim they are. To answer these questions and quash some of the myths surrounding the technology, it’s time to ask the experts.
1. LED lighting is expensive In the early days, pricing was the biggest hurdle to overcome when it came to the widespread adoption of LED lighting systems. But as time has moved on, so has the technology and financial support around installations, making it now easier than ever to make the change and save money. While the initial investment in LED systems is higher than that of conventional systems, the ROI has a fast turnaround, especially when taking energy costs and maintenance into consideration. Due to the long life of LEDs, no replacements are required for around 10 years, with end users able to expect an energy saving in the region of up to 80% compared to traditional lighting systems. Because of this, economic payback can typically be achieved in less than two years.
2. Financial help isn’t for everyone
“The health risks that are associated with LED lighting often refers to older models and low quality products”
Leasing-style schemes are ideal for all types of applications, big and small, including factories, warehouses and exterior lighting, as well as offices, retail, hotels and education. Installing LED technology is now actively encouraged as the UK sets out its plan for net zero, so more support is becoming available to help organisations make changes. Even with financing arrangements and backing, projects are typically cash positive right from the start. There are also energy and council grants available across the country for assisting SMEs with carbon reduction.
3. All LEDs work the same
One of the most common mistakes that people make when installing new lighting is choosing substandard fittings. Initially, they will save sites money on energy, but those savings are quickly spent in maintaining and replacing them. When exclusively looking at cost, the least expensive choices seem to make the most sense. However, this line of thinking does not account for all the aspects of efficient project investments and businesses can easily run into higher expenses when a ‘one-size-fits-all’ mentality is used to work out opportunity costs, system, lifetime and maintenance costs. Businesses across numerous industries can fall into the trap of choosing the least expensive way to fix a problem based solely on immediate ROI and end up having to redo the project only a few years down the road. When replacing lighting, decision-makers need to be thinking long term, understanding what an investment will look like over the next 10+ years and the best ways to upgrade systems with longevity.
4. LED lighting has health risks LEDs do not contain mercury, lead or other toxic materials and are completely recyclable just like most other electronic devices and are as safe to the eyes as any other artificial light source. They are not like lasers, the light is not focused to a single point, and the intensity is comparable to traditional bulbs and halogen lamps.
50 | July 2021

electricalcontractingnews.com
It is said that LED-based light sources are different from traditional lamps in that they contain more blue wavelength light which is harmful to human beings. But according to an evaluation report by the European Lighting Industry represented by ELC & CELMA, in terms of their level of photo biological safety, LED lamps are no different from traditional incandescent lamps and fluorescent tubes. In fact, the portion of blue in LEDs is comparable with that of the blue in lamps using other technologies at the same colour temperature.
5. Point for point replacement is not always best When creating a lighting scheme, introducing luminaires with a slightly higher wattage but a clever optical design will require less fittings to provide a better quality of light. Fewer fittings means reduced energy consumption, product costs, install costs and less, if any, maintenance. Point for point replacement can seem like the easy option, but it is not necessarily the most effective method when it comes to cost and energy efficiency. It might be seen that having less fittings installed will be counterproductive, but with the right technology and lighting professionals on board, there are many factors that need to be considered in order for savings to be made. This includes analysing the difference and wattage between the lighting being removed and what it is being replaced with and taking into consideration whole-life cost, which refers to the total cost of ownership over the life of an asset. LED lighting is always improving, and the LEDs of today are not the same as the first generation, which are often criticised. The health risks that are associated with LED lighting often refers to older models and low quality products, which is why it’s absolutely vital to work with an LED lighting specialist when upgrading lighting systems.

EXTERIOR LIGHTING IN A COMMERCIAL SETTING Whether you’re working on task lighting for safety or ambient lighting to produce a comfortable level of brightness, to ensure each fitting fulfils its main function, Red Arrow advises taking the following points into consideration.

must-have for commercial buildings, businesses and those in charge of public spaces, outdoor commercial lighting is often implemented to provide sufficient light to keep exterior areas illuminated. Designed to be robust, durable and long lasting, its main purpose is to drastically influence a building’s safety, security and visual appeal. However, while you will be aware of challenges such as light pollution, light spill and glare, key specifications of each fitting should also be an essential part of each installation.
Ingress Protection (IP) In an environment where dust or water could damage electrical components, a sealed enclosure is used to prevent exposure to elements – the IP rating then indicates the type and degree of ingress protection. While IP44 and IP54 fittings are commonly purchased in the belief they’re fine for outside, in areas where the fittings are exposed to the elements, upgrading to IP65 will often be the better choice.
Impact Protection Rating (IK)
Energy efficiency
Indicating the degree of protection provided by the electrical enclosures against external mechanical impacts, IK rated products are important for lighting used in busy public spaces. Or in industrial areas, where they need to be robust enough to take knocks and withstand heavy use, such as the non-corrosive linear fittings, Weatherguard and Weatherguard Plus.
By updating exterior lighting, a commercial business can reduce its energy usage and its environmental impact, particularly if current light fittings are inefficient due to old technology or the degradation of diffusers. New generation LED fittings can be more efficient than earlier generations of LED fittings.
UV stability Designed to protect a fitting from long-term degradation of UV light, UV stability is essential in preventing the slow photo-degradation of plastics, which can cause discolouring to a brown/yellow tone. It also reduces the loss of elasticity, an issue that causes the plastic to become brittle and more prone to breaking on impact. Without UV stability, a light fitting can also turn ‘chalky’, impacting on its efficiency and light transmission.
Sustainability By updating exterior lighting, a commercial business can reduce its energy usage and its environmental impact

LEDs have long lifetimes, but their life is dependent on correct operations, not overloading them electrically or thermally, using quality materials and efficient manufacturing processes. To further increase LED sustainability – eliminating the need to replace the whole fitting at the end of its life – you can also install replaceable gear trays, or GTRs. Designed to easily retrofit into the fitting and lengthen their lives, these gear trays reduce material waste and landfill, while also saving cost and inconvenience of rewiring and replacing the whole product. From floodlights to wall lights, canopy lighting and pole mounted fittings, exterior lighting is essential for most commercial buildings. Red Arrow, redarrowelectrical.co.uk

or nearly two decades, Q Catering has been operating as a leading delivered wholesale foodservice provider to caterers across Kent and East Sussex. Based in Sittingbourne, the company supplies a vast range of products which includes frozen, ambient and chilled, as well as janitorial and disposables. With this level of stock to cater for, significant warehousing and storage capacity is required. When a decision was made to upgrade the outdated lighting provision in the warehouse, Ovia’s Inceptor Hion 200W LED Dimmable Highbay fittings were selected to provide a high performance, more energy efficient LED alternative to the fluorescent fittings that had been in place since 2003.
Ovia’s Inceptor Hion 200W LED Dimmable Highbay fittings were selected to provide a high performance, more energy efficient LED alternative
A clear vision Q Catering needed to address the poor visibility that staff were having to endure during the night-time stock picking sessions, with the original lighting solution not reaching the bottom two rows of shelving. The company responsible for the electrical installation was Kent-based Prowired Electrical Contractors, which offers a wide range of electrical services throughout the south east region. Danny Edmonds, Director at Prowired, had no hesitation in approaching the team at Ovia with whom he has had a long-standing relationship. Ovia Regional Sales Manager, Reg Oldrey, came up with the lighting design, in conjunction with the requirements set out by the client. Commenting on the project, Danny Edmonds says: “I’ve known Mike Collins and Reg Oldrey at Ovia for many years. It’s a highly respected company with a

reputation for quality and reliability. I’ve worked with them on many projects and trust their judgement when it comes to specifying the right products to deliver the solution needed. I’ve used the Inceptor Hion fittings previously and they were perfect for the job – easy to install, producing excellent light quality and saving energy in the process, compared to the original installation. The client was delighted with the result.”
Fit for purpose In total, 12 of the 200W dimmable Inceptor Hion Highbay fittings were installed. There are two versions available – the 0(1)-10V dimmable version installed at Q Catering

and a microwave sensor version. Both boast an IP65 and IK10 rating – IK10 is one of the highest degrees of mechanical protection defined by BS EN 62262: 2002 standard. They are each available in three wattages – 100W, 150W and 200W options – and in a choice of a black or white finish. The Hion fitting is suitable for suspending from ceilings or wall mounting using the appropriate bracket which is available separately. It comes with 3m, pre-installed H05RN-F cable for quick and easy installation, and it offers a range of features. It is dimmable, delivers a 90° beam angle, offers 54,000-hour lifetime and comes with a six-year warranty. Ovia, oviauk.com

LED DIMMING MODULES CHOSEN FOR BASEMENT CONVERSION Kieran Logan of Rose Electrical Contractors talks to Zano Controls about a recent project where he used 11 ZMO150 module dimmers to provide flicker-free and silent lighting control within a multi-functional excavated basement conversion in Leeds.
W
hen extending your dream home, creating a liveable area under the existing property is an option increasingly sought after by homeowners looking to add extra space without extending wider, longer or higher. Electrician Kieran Logan was brought on board to complete the first and second fix of a domestic electrical installation for a home extension project by building firm, C & A.J Marshalls. The project was a big one - the property was already well extended with an outwards kitchen extension. On a mission to add a gym, swimming pool, cinema and family room, the homeowners decided that excavating the basement level of the property to fulfil their dreams was the best approach. The excavation of the basement had to happen without any demolition of the property itself, so sitting directly under the property, the builders had to underpin the existing structure of the basement to replace the lost foundations and restore the building to full strength. The project took nearly two years to complete, and 12 months into the project Kieran got started on the first fix, with the second fix taking six months.
Excellent lighting design Working in conjunction with Horsley Townsend Architects, who specified the lighting design scheme to include lamps and fittings from Astro Lighting, it was up to Kieran to provide and pair the lighting scheme with the right products to provide flicker-free and silent LED dimming control. Both gyms and swimming pools have unique lighting needs and require adequate lighting to match. Not only does good swimming pool and gym lighting help to provide a wow factor, but LEDs make it possible to alter the mood of the gym and swimming pool to create the right environment. As the lighting design scheme spanned across the basement conversion that consisted of the gym, swimming pool, cinema and family room and the stairwell into the upstairs/ground level floor of the
56 | July 2021
LED Lighting – Zano Controls.indd 56
property, it was key that the right products were chosen to provide the correct lighting levels specific to each room. Recessed LED fixtures in pool areas are a great way to create a relaxing glow from the pool at night, but as with any lighting project where electricity is in close proximity to water, care needed to be taken and the regulations followed to ensure that the fittings were safe to use in zones one and two of the pool area. The ground floor works also included another family room that had an apex vaulted ceiling and a structural glass floor close to the stairwell that let light into and led down to the basement conversion. For the ceilings, Kieran used a mix of surface spotlights, Astro Lighting’s Lynx fittings at 12.5W each, and recessed spotlights, Astro’s Trimless Luminaires, that had to be installed before the final plaster skim and were IP65 rated. For the areas across the basement conversion – which required small sections of LED tape to highlight and wall wash specific zones and provide a feature glow – Kieran used Aurora’s LEDline PRO single colour 24V super bright LED strip. Both the surface and recessed ceiling spotlights and the LED strip lighting required lighting control to match and provide low-level dimming capability across the various rooms in the basement. Plus, in the stairwell that led to and included the family room on the ground floor level. As the ZMO150 was Kieran’s go-to dimmer, which he’d used before on countless projects, he knew he could count upon the fact that it would just work. Kieran calculated the total wattage across the number of circuits the project required and, in each instance, the ZMO150 became the dimmer of choice. As all circuits came to a combined total wattage of less than 150W/VA, the ZMO150 was the ideal solution. Providing 0-150W of flicker-free and silent dimming control, the ZMO150 was perfect for achieving a low lighting level in the cinema room and making full use of the total load elsewhere, for example, in the gym and swimming pool. As lighting control was a key part of the brief, and the homeowners wanted to ensure control was made by a rotary controller in keeping with the same aesthetic and style as the rest of the property, Kieran matched the ZMO150 with chrome plates and a rotary knob from Click Scolmore.
Installation Eleven ZMO150s were installed across the project in total. Across the downstairs basement conversion, Kieran had seven lighting circuits each connected to one ZMO150, and in the upstairs family room that led down to the basement and the apex vaulted ceiling area, four ZMO150s were used. In the pool area, Kieran used Astro’s Trimless range of recessed spotlights, pairing two ZMO150s 10 than 10W each, across two circuits. Each circuit produced a combined load of 62.5W, and with plenty of room left to allow for Inrush, each circuit was connected to one ZMO150. In the cinema room, Kieran paired four Astro Lynx surface spotlights at 12.5W each with a small section of LED strip lighting around the back of the 48-inch cinema screen. He did this on one circuit with one ZMO150 to provide flicker-free and low-level lighting control. In the gym, Kieran also paired four Astro Lynx surface spotlights and roughly a metre and a half of Aurora’s LEDline with one ZMO150. LED tape and strip lighting lists wattage per metre, which often makes it difficult to calculate an installation precisely and it’s the LED driver – and the huge inrush it consumes – that skews the wattage listed on the label significantly. However, in neither the gym nor the cinema room was much LED strip lighting required. The total load that included the 50W generated by the surface spotlights and the power consumption of 19.2W per metre listed by the LED strip lighting came to less than 150W/VA, with generous Inrush allowance accounted for. In the basement family area that joins the gym and cinema room, Kieran had two circuits each with a ZMO150 module dimmer connected to seven Astro Lynx surface spotlights. Upstairs, within the family room that went from the kitchen and led down to the basement, two ZMO150s were used across two circuits each with several Astro Lynx surface spotlights on. And within the Apex vaulted ceiling area used six Astro Lynx surface spotlights were used – four connected to one ZMO150 and two connected to another.
The project took nearly two years to complete, and 12 months

ADVANCED LIGHTS THE WAY AT UNIVERSITY OF BRISTOL The University of Bristol’s emergency lighting upgrade continues with the installation of a further 10 LuxIntelligent emergency light testing panels from fire and life safety system manufacturer, Advanced.
T
he new equipment will be installed alongside 21 existing LuxIntelligent panels linked to around 4,500 light fittings, to ensure ongoing compliance with the BS 5266-1 code of practice for the emergency lighting of premises. The LuxIntelligent panels will continue to be retrofitted across a range of university buildings, including seven halls of residences, using existing cabling. The ease with which LuxIntelligent can be used to replace outdated emergency lighting on existing sites allows significant time and cost savings to be achieved. A variety of LED luminaires have been chosen from the LuxIntelligent range, to protect buildings with very different lighting requirements. They include downlighters, spotlights, exit signs and bulkhead lighting that complement equipment already installed in the historic Victoria Rooms, the Wills Hall halls of residence, as well as operating theatres and abattoirs in the veterinary college campus. Chris Smith, Commissioning Engineer at the University of Bristol, says: “We fit various emergency lighting systems at the University of Bristol according to

individual building requirements, however the emergency lighting in some areas of the University had become outdated and we could no longer source replacement parts, making repairs increasingly difficult. Having used Advanced’s emergency light testing system across other parts of the University for many years, I was confident that we could rely on it for performance, compliance and peace of mind.” Matt Jones, Emergency Lighting Business Manager at Advanced, says: “It’s fantastic to see our emergency light testing systems standing the test of time and being chosen for this major upgrade at the University of Bristol. We look forward to continuing to support the University as their future emergency lighting requirements grow.” LuxIntelligent from Advanced is an addressable, automatic emergency lighting test system, that shows all emergency lights are compliant and functioning, with no engineer involvement required. Each panel has up to four loops each, supporting 249 luminaires, and can be easily networked to work with existing wiring and luminaires, keeping installation costs to a minimum. The system also offers optional cloud monitoring and system management via mobile and web apps.
LuxIntelligent can be used with EasySafe, Advanced’s latest range of addressable, low voltage emergency luminaires and exit signs. Powered directly from the LuxIntelligent panel, EasySafe devices need no local power supply and are compatible with any existing LuxIntelligent luminaires and exit signs, enabling the easy installation of devices onto existing wiring to form one intelligent emergency lighting system.

THORN ENSURES THE PERFECT SETTING Thorn Lighting has supplied its stylish Dyana aluminium road lanterns for Queens Quay, one of the most significant regeneration projects in Clydebank, West Central Scotland.
T
he project is part of a larger urban regeneration development that is taking place around the Titan Crane, a major landmark and tourist attraction in the Clyde Basin and the old John Brown shipyards in Clydebank. A Queens Quay design code has been put in place to ensure a high quality, sustainable development, so it was important that the lighting helped to create an inviting public space that also enhanced the surrounding developments. The 24-hectare Clydebank site is one of Scotland’s key waterfront regeneration opportunities, with huge transformational potential for the town. The once thriving industrial yard was famous for building the QE2 and Queen Mary. The masterplan is to deliver a vibrant mixed use community that extends Clydebank’s existing town centre down to the riverside, enjoying public access to, and focus on, the river frontage, historic dock and iconic Titan Crane. The Titan Crane is the focus of plans to regenerate the Clydebank waterfront, where visitors are able to take the lift to the top of the 150 feet giant crane and walk

along the jib and see stunning views of the Clyde and the surrounding landscape. Thorn worked on the project with landscape architect, RaeburnFarquharBowen, and mechanical and electrical consulting engineer, Henderson Warnock, and agreed Thorn’s Dyana lanterns would be the perfect choice. With its sleek aesthetic for modern or traditional applications, the Dyana fittings have been mounted on bespoke aluminium columns in two different sizes, in a tapered style with decorative finials. Dyana is a stylish, IP66 aluminium road lantern that incorporates a flexible optical engine and delivers glare-free white light for a more pleasant urban environment. The lantern incorporates an electronic and dimmable gear for reduced energy consumption and maintenance, provides high efficiency of up to 150lmW and is tested to IK10. This high-quality LED luminaire efficiently enhances urban roads and streets up to ME2 and has made Queens Quay an inviting public space that will blend smoothly with the surrounding developments Lisa McRavey, Senior Landscape Architect at RaeburnFarquharBowen, comments, “Our masterplan design at
Queens Quay celebrates the industrial heritage of the site, and seeks to re-engage the town and its people with both the site and the waterfront. The centrepiece of the development is the old fitting out basin, re-imagined whilst retaining its strong industrial character and aesthetic to provide both a fitting commemoration and tribute to the past, and a vibrant and accessible public space for the future. Thorn really understood the importance not just of light quality and reduced energy consumption in providing a public space for the future, but also of finding the appropriate aesthetic in such a high profile and historically important site - and worked well with the team to ensure the best design solutions were achieved.” Andrew Smith, Senior Electrical Design Engineer at Henderson Warnock, states, “We specified Thorn for the project as we have a good relationship with them and can rely on the company’s products to deliver the required results in an environmentally sound manner. The lighting forms an intrinsic part of this project, which will benefit the residents and businesses of Clydebank and beyond.” Thorn Lighting, thornlighting.co.uk

FIRE AND CARBON MONOXIDE PROTECTION FROM AICO The Ei1000G SmartLINK Gateway from Aico is an innovation in the area of fire and carbon monoxide (CO) protection, providing remote data insight and event notifications for multiple connected alarm systems.
T
TheEi1000G SmartLINK Gateway from Aico
he Ei1000G communicates with smoke, heat and CO alarms and accessories within a property wirelessly via RF signals, utilising Aico’s latest SmartLINK RF protocol. Its built-in GSM data connection is then used to send real-time data up to the SmartLINK Cloud Portal. Once the data is in the cloud, the web-based portal can offer reporting on fire/CO alarm activations, alarm head removals, test button activations, alarm locations within the property, alarm age, alarm replacement dates and issues with the mains power supply, providing full visibility of the status of the alarm system within the property remotely, without having to gain access into the property itself. The Ei1000G is the first cloud connected IoT (Internet of Things) product from Aico and is another in the company’s long history of innovation. The requirements for data extraction from alarm systems has been steadily evolving. Data can provide invaluable insight into what has happened within an alarm system should someone be visiting a property to perform maintenance. It can also be used in the area of compliance and asset management – providing a full record of every aspect of an alarm system including who installed it, when it was installed, the status of all alarms within the
system, a record of any events including activations and tests of the system performed. This can be particularly useful in demonstrating that an alarm system is functioning correctly, with the key aspect being that the data is transmitted via the Gateway to the Cloud Portal, meaning that all data can be accessed remotely. The development of the Aico SmartLINK Gateway has been greatly influenced by Registered Social Landlords (RSLs) and their teams, through extensive feedback and rigorous trials that have significantly shaped the final product; Aico designed this alarm management system to assure tenant safety at any time. As the pinnacle of Aico’s technology, this pioneering product facilitates the safety of tenants at all times and aids with compliance across housing stock, ensuring ease of monitoring for RSLs and clear, actionable intelligence. In addition, the data connection from the Gateway up to the Cloud Portal is secure, using AES128 data encryption. The Gateway also verifies its connection to the Cloud Portal via a check-in ‘heartbeat’ that is sent to the Portal every 12 hours. Any events within a system (e.g. fire alarm activation) are sent up to the Portal immediately. Text and email notifications can also be configured by the user for any Gateway connected system under their account.
If an event such as an alarm activation occurs and contacts have been assigned to the system, all contacts will receive a text message and/or an email notification giving details of the event, the property address, the alarm that has activated, its location and the time and date of the event. The Ei1000G SmartLINK Gateway gives a proactive approach to fault-finding, defining any trends in alarm activations and maintenance requirements, while drastically minimising the issue of property access, paving the way to a solution-focused approach to asset management. Aico, an Ei Company, is the European leader in home life safety, pioneering new technologies and offering high quality alarms, developed and manufactured in Ireland. All Aico alarms meet UK standards and offer a variety of sensor types to guarantee protection for every home, the cornerstone of which is delivering education, quality, service and innovation. In 2020, Aico expanded its connected home offering with the acquisition of leading Internet of Things (IoT) solutions provider, HomeLINK. HomeLINK leverages cutting edge smart home integration and analytics technologies, providing a complementary platform to present a synergistic approach to IoT.
