Editor’s Viewpoint

Brexit strategy provides opportunity to ‘build back better’ After seemingly dominating our thoughts and conversations since the referendum vote was announced, it would have been almost inconceivable to consider that during 2020 our 'Brexit' from the EU would be so quickly cast to the back of individuals' minds.

The global pandemic has quite rightly grabbed the headlines, and will continue to do so for many more months following the announcement of the latest 'hard' lockdown, which the government insists will give the country the time and breathing space to flatten another sharply rising curve.

Should the (very) ambitious plan of a vaccine roll-out to those in the most vulnerable categories by the end of this month prove successful, we may all start to see brighter skies ahead.

The uncertainty around our departure from the EU is just another weight that the UK has had around its neck, so now that the PM has finally managed to negotiate a trading agreement with the European Union, a clearer path is emerging.

Although there is an incredible amount of detail to pick through, much of which is beyond the comprehension of the normal 'layman', one of the most positive aspects appears to be in the fact that the UK will have a 'wide-ranging' free trade agreement with the EU, which takes the uncertainty of a 'no deal' off the table and will ensure that cost and availability of the products and equipment that construction professionals rely on doesn't suddenly go through the roof overnight.

Many of us will have seen the images of the lorries and trucks queued in Kent prior to Christmas, and looked at this as a surefire sign of things to come. The good news, however, is that agreements are in place to ensure better co-operation at the border, while the UK will now be recognised as a tax-sovereign nation, which will give it the power to set and control its own taxation system.

One area of particular concern was the threat of tariffs and quotas being introduced against import and export goods, but our government has done a good job of ensuring this will not be the case. In turn, businesses and organisations now have the capability, at least, to plan for the future without those dark clouds hanging over them.

And, let's not beat around the bush, despite the huge difficulties we've all faced over the last 12 months, the construction sector is one that will have a very bright future with the government offering grants to stimulate activity and a country that needs more homes and a better, more agile office infrastructure, in the wake of the COVID-19 pandemic.

Personally, I've always championed the fact that the UK would have the chance to dictate its own future and have long called for a return to our 'roots' so that we can start making things again and produce skilled professionals that are the envy of the rest of the world.

The assurance of affordable access to construction materials is certainly one less thing to worry about and will make the government's task of 'building back better' an eminently more achievable one.

There will no doubt be some additional pain to come as the full detail starts to emerge but, after what has been a very difficult start to 2021, there is certainly reason for optimism moving forwards.

Are you optimistic about the future? How do you plan to shape/evolve your business in the wake of the challenges we're facing? We'd love to hear your thoughts on this or any other subject that you're passionate about, and we'll share the best and most interesting views on these pages.

Survey suggests signs of recovery despite looming uncertainty More than 2 out of 5 businesses (4%) expected their turnover to fall by the end of Q4 2020, according to a new engineering services sector survey.

The same survey also revealed that just under 1 in 3 businesses (30%) say they're not clear about the forthcoming business implications of Brexit.

However, the survey highlights a significant shift towards recovery compared to Q2, when almost two thirds (60%) of businesses reported a drop in turnover during the first half of the year.

Nearly two thirds (64%) of businesses reported the same or increased turnover in Q3, with only one third (35%) reporting a decrease.

Industry shockwaves Rob Driscoll, ECA Director of Legal & Business, said: “The engineering services sector typically feels the impact of economic downturns later than the rest of the economy, but the shockwave of coronavirus in Q2 was unprecedented for both demand and supply within the sector.

“We're likely going to be on the road to recovery for a while longer.”

He continued: “The industry has shown great resilience and signs of recovery in the second half of a very tough year.

“This bodes well for 2021 which will reveal the true impact of Brexit, bear the financial impact of COVID-19 at year end, the culmination of claims and the challenges of changes to VAT, CIS and IR35.”

Increased agency worker use Employment of agency workers and subcontractors rose for the first time since late 2019, with just under a fifth (17%) reporting increased use of agency workers or subcontractors – almost double the figure reported in Q2.

Engineering services businesses continue to feel mounting cost pressures, with over half (51%) of survey respondents reporting an increase in material costs in Q3 compared to Q2.

Getting paid on time also continues to be a challenge for businesses.

Despite public sector rules mandating payment within 30 days, less than half (41%) of direct contracts and just 27% of indirect contracts in the public sector were paid during this period.

ERA donates to children's hospices ERA has donated £8,000 to Hope House Ty Gobaith Children's Hospices while making it the company's nominated charity for the second year running in 2021.

The charity is set up to provide support to families in Shropshire, Cheshire, Mid and North Wales who are either caring for a terminally ill child or whose child has died.

Commenting on the donation, Simi Epstein, Director of Fundraising & Marketing at Hope House Ty Gobaith Children's Hospices, said: “We were completely stunned at the staggering donation of £8,000 which we received from ERA Home Security. I can't begin to put into words how grateful we are."

Manrose launches digital channels Manrose has recently launched two new digital channels to make it even easier for customers to access product information they need.

Aico conquers charity Lapland Challenge In support of the Derwen College Charity and the Agnes Hunt Village Project, Aico colleagues – both locally and across the UK – recently took part in the DC to Lapland Challenge.

The Derwen College Charity was set up in support of the students at Derwen College with disabilities and learning difficulties. The College has provided education and care for students for over 90 years, aiding them to live more independent lives.

All fundraising efforts are put towards specialist equipment and opportunities for the students enabling them to reach their full potential and develop their independence skills.

Custom-built housing In 2019 the charity launched a project to develop the Agnes Hunt Village, a custom-built housing area, utilised by those with Special Educational Needs and Disabilities (SEND).

The village is essential for the students, enabling them to develop their everyday skills such as housekeeping and caring for themselves. However, in order to provide this

real-life education to as many students as possible for their life after college, the village needs to be modernised.

The December challenge was to cover the distance from Derwen College in Gobowen to Lapland in 10 days at the beginning of the month by walking, running, cycling or any other way of covering miles with physical activity.

Over 20 Aico colleagues, alongside 30 members of staff, including the students and their families, took on the virtual challenge to make it the whole 1,989 miles to reach Lapland.

Aico’s campaign was able to raise £325 for the event, helping Derwen College to reach a total of £1,700 to be put towards the critical education it provides.

'Game changing' Bill for online electricals is announced Electrical Safety First has put forward a ‘game changing’ Bill, aimed at addressing the problem of purchasing dangerous electrical equipment online.

The new Bill would make online marketplaces – such as Amazon and eBay – legally responsible for hosting listings of potentially lethal electrical products for sale. It would ensure they have the same responsibilities to protect consumers from unsafe products as High Street retailers.

The government’s Online Harms Bill was developed in response to increased concerns around online personal security – particularly for children. Its declared objective is to establish a system of accountability and oversight for tech companies. But while the Bill covers various ‘harms’ arising from social media, fake news, or other illegal content on the web, ESF argued that it didn’t go far enough.

Electrical Safety First’s proposed Bill, if accepted by government, would tighten the law so that online marketplaces must ensure electricals

sold from a fulfilment centre, or third party seller on their site, are safe. And they would be required to alert consumers who have bought a substandard electrical item from their marketplace.

Lesley Rudd, Chief Executive of Electrical Safety First, said: “We don’t just want online marketplaces to react to risk, we want them to be proactive.

“Given the sophisticated technologies available to these retail giants, it is not unreasonable to expect them to ensure effective safeguards – whether from revised algorithms, machine learning, or improved image recognition – to stop unsafe electricals being sold on their platforms.”

She added: “There is support – research undertaken for us by ComResiv, found that 70% of MPs want online marketplaces to have a legal responsibility to help prevent the sale of dangerous electrical products.

“We believe our proposed Bill would not only improve consumer safety but also protect legitimate businesses that are selling online.”

Are electricians the Toughest Trade?

Swarfega is once again on the hunt for the Toughest Trade in the UK. Following the success of plasterers in 2018, mechanics in 2019 and farmers in 2020, skin care expert Swarfega is looking to crown the toughest trade out there in 2021.

Launched last month and running through to March, Swarfega will be challenging tradespeople to post a picture of them or a colleague battling their toughest task on the Swarfega Facebook or Twitter page, along with the hashtag #ToughestTrade and a short reason why their trade should win 2021’s accolade.

Using a special Tough-O-Meter, Swarfega will judge each picture and choose the one showing the toughest task. The top four entries will then be narrowed down and the winner will then be put to a social media vote.

The winning individual will receive £200 in Amazon vouchers and the trade that the winner represents will be crowned Swarfega’s New Toughest Trade for 2021. The runners-up in places 2-4 will also receive a £50 Amazon voucher.

COMMENT

“GOING GREEN WILL PAY DIVIDENDS” Robin Francis, Managing Director at National Ventilation, explains more about how the government's Green Homes Grant works and why it's so important for electricians to get involved.

T

he Green Homes Grant was launched by the government in September of last year to help boost the uptake of energy saving home improvements and assist with reaching the goal of net zero carbon emissions by 2050. The original deadline for improvements was March 2021 but this has since been extended to March 2022, meaning electricians now have plenty of time to sign-up to the Green Homes Grant and undertake work through the scheme.

In short, the vouchers on offer as part of the grant can be used to cover up to two-thirds of the cost of works, up to £5,000 or up to £10,000 for low-income households. This work must include at least one 'primary' measure, such as improved insulation or low carbon heating.

The good news for electricians is that 'secondary' measures can then be added, including triple glazing, draught proofing, heating controls and, importantly,

improving or repairing controlled ventilation systems.

How can you get involved?

For electricians who want to undertake work under the grant the first step is to be registered with TrustMark. To do this you must meet Publicly Available Specification Standards (PAS 2030) to install energy efficiency measures. Once registered, you’ll be added to the certified installers directory, which homeowners and landlords will be able to contact you through for a quote.

Don’t forget the ventilation For anyone undertaking energy efficiency improvements under the scheme (or at any other point), ventilation should never be an afterthought. Any works that make a home more airtight to improve energy efficiency can result in poor indoor air quality (IAQ), condensation and mould if ventilation is

12 February 2021 PROFESSIONAL ELECTRICIAN

not improved at the same time.

The reason for this it that when a home is made more airtight it can no longer ‘breathe’ to allow polluted and stale air to escape the house. Without effective ventilation this can build up, resulting in indoor air pollution. Moisture in the air also can’t escape, causing condensation to form which can potentially cause black mould to grow. This is both unsightly and can lead to serious health problems.

Fortunately, the government has identified these issues and the negative

012_PE_FEB21_Layout 1 04/01/2021 15:37 Page 13

impact on both IAQ and resident health. As such, the Green Homes Grant scheme allows for ‘repairing and improving controlled ventilation’ as a secondary measure under the scheme.

Therefore, electricians are well placed to work alongside other trades to ensure effective ventilation is installed to create a healthy home environment. This is also in-line with Building Regulations where installers need to comply with the legal requirement that a home’s IAQ must not be made worse by adding insulation, double glazing or draught proofing measures under the scheme.

A cost-effective route to compliance within the Green Homes Grant scheme is to install intermittent extract fans of the right size in ‘wet’ rooms and to ensure fresh air enters the building through background ventilators without causing draughts.

Green Homes Compliance Scheme To make things simple for installers the Green Homes Compliance Scheme has been launched. This provides guidance on how to ensure sufficient ventilation in a home when air tightness has been improved. It also has the added benefit of helping electricians to easily identify suitable products from companies like National Ventilation.

These accredited products carry the

Green Homes Compliance badge, which demonstrates that fans will meet Building Regulations requirements and deliver effective ventilation. It also gives extra peace of mind that legal requirements have been met.

Ventilation solutions To ensure good IAQ and a healthy home, any ventilation improvements should be carried out at the same time as any of the primary energy efficiency measures under the scheme. When choosing which fan to install it’s vital that it will extract air at a sufficient rate when installed to remove polluted air whilst overcoming any resistance to air-flow from ducts or grilles.

What else is there to consider?

The essentials of ventilation include ease of installation, reliability, effectiveness, quiet operation and install location. When installing a fan in a bathroom, the ideal choice is a fan that offers all these and that can also be installed safely in the splash zone.

For example, the Monsoon Zone 1 Silence range from National Ventilation provides high extraction rates with low energy use of just 7.5kW and a low SFP of 0.33w/l/s and exceptionally quiet running levels of just 22d B(A).

It has an IP45-rating so can be safely

installed in Zone 1 without the need for a low voltage transformer, making it ideal for a small bathroom.

It also has two speeds and a range of control options, including Basic, Timer, Humidistat and PIR. Plus, it also makes the installation easy for electricians thanks to a larger terminal block, making wiring easier.

Another good option is an in-line mixed flow fan which can be used for exhaust and supply ventilation for rooms with high humidity, such as bathrooms or kitchens that require high pressure and powerful airflow.

For example, National Ventilation’s UMD range of domestic mixed flow fans combine high performance of up to 198m3/h with power consumption as low as 17-19W and low noise levels of just 28dB(A) on low speed. The fans are also IPX4 rated and feature a two-speed motor equipped with Standard Thermal Overload Protection for extra safety.

The Green Homes Grant scheme not only aims to help the UK on the road to zero carbon but presents a great opportunity for electricians to gain additional work in the installation of ventilation. With the Compliance Scheme providing ventilation guidance and a product finder, there’s never been a better time to sign up for the scheme if you've not done so already.

Letters Were you in the Class of 1971?

Dear PE, 50 years ago (6th September 1971, to be exact) over 80 electrical apprentices started their careers in the industry as apprentice electricians with the East Midlands Electricity Board at the fabulous (and then recently opened) Wollaton Craft Training Centre in Nottingham.

To celebrate this milestone anniversary, we need your help (along with your readers) to find as many of those apprentices and instructors as possible, as we plan to hold a reunion event later this year.

Most of the individuals pictured will be around 65 years of age now, some retired and others running their own companies still.

Others may have left the industry altogether – we just don't know.

To offer some help in locating some of the individuals involved, I've included two photos of the group, who all originally came from areas such as Boston, Lincoln, Grantham, Nottingham, Derby, Burton, Chesterfield, Leicester, Loughborough, Hinckley, Mansfield, Coventry, Warwickshire, Milton Keynes, Corby and Northampton.

If you spot yourself in the photo, or know someone who may have been in that intake, please email: ian@iseco.co.uk Kind regards, Ian Smith, MD, Ian Smith Electrical

Is the EICR 'pass' just a farce?

Dear PE, Having read a recent edition of the publication, I was dismayed – but not surprised – to read two letters to the Editor complainng about the poor quality of EICRs. In my experience it seems to be a well known fact that few EICRs are actually undertaken correctly.

Until a few years ago I was a practicing electrician registered with one of the main CPS providers, but retired in desperation at the poor quality of EICRs I was seeing regularly. Quite simply, I could not and would not compete with the cowboys.

The current 'going rate' in Sheffield is £170 and the time taken to undertake the inspection, including the paperwork, is less than two hours. I personally watched an electrician perform an EICR in a two bedrooomed flat in under half an hour. The test seemed to involve counting the outlets and taking a picture of the inside of the consumer unit. I questioned the electrician about what he was doing and he didn't even know what a C&G 2391 was.

Why wouldn't landlords welcome these checks, as they're legally covered once they obtain a pass certificate, regardless of the quality/thoroughness of the EICR? I spoke to one landlord who'd had EICRs on three flats and a house undertaken in less than five hours!

Will it take a disaster before something is done to raise the standards of these inspections?

COMMENT

“WHAT YOU DON'T KNOW CAN HURT YOU”

Stewart Gregory, VP of Power Products at Schneider Electric, discusses why it’s essential to keep up with new innovations as they arrive.

I

nnovative technologies are now used to facilitate business operations across a vast number of industries.

The electrical industry is no exception. Change in the electrical industry has moved so rapidly that those who were slow to catch on are now being left behind.

In the meantime, those who welcomed new innovations as they arose have benefitted in a multitude of ways.

Recognising the opportunity Given the increasingly competitive and constantly progressing nature of the industry, it has never been more critical for electrical contractors to stay on top of the latest products, trends and techniques to be competitive.

Yet, as the importance of software and connectivity continues to grow, the sector is becoming increasingly divided, slowly splitting between those who recognise the opportunity and those who are yet to be convinced. For those that wait too long the chance of catching up diminishes, as the capabilities gap continues to grow.

An unprecedented number of installers and engineers will soon be retiring from the electrical industry. This provides the

opportunity to upskill the sector ‘en masse’. Those currently in the profession, as well as those entering it, need the training to prepare them for the rapidly digitising workplace.

End users are digitising, and electrical engineers need to digitise along with them, otherwise companies may find themselves unable to fulfil the needs of their customers.

In the residential sphere, customers are demanding smart homes whilst in corporate buildings, energy management systems. To match changing customer expectations, electrical contractors need to get trained on what these products are, the benefits, and how to install them to avoid being left behind.

Gaining a competitive advantage The opportunities which digitisation and innovation present to the electrical industry are emerging fast. These include energy management, predictive and preventive maintenance, service contracts and reduced running costs for the client.

Those businesses which successfully implement new technologies are set to receive a number of overarching benefits.

Working with the latest technologies

16 February 2021 PROFESSIONAL ELECTRICIAN

can majorly improve efficiency for electrical contractors, ultimately giving them an edge in this competitive market.

For example, working on boards with plug-in components, such as Isobar P, cuts the wiring time in half for the electrical contractor as well as leveraging connected technologies that allow users to instantly monitor the health and energy usage of their distribution boards, via simply connected software packages. This means the electrical contractor saves time on the installation whilst the end user saves money through greater connectivity.

Furthermore, digital advancements have brought changes to product configurators. If you’ve designed a system with different connected components, electrical contractors no longer need to spend time either speaking to a third party or looking up each product to ensure

016_PE_FEB21_Layout 1 04/01/2021 15:40 Page 17

they're all compatible.

Thanks to the digitalisation incorporated by Schneider Electric, compatibility can be quickly and simply checked – all via a mobile phone.

Electrical contractors can simply download a simple App, connect to the board and check the compatibility of different components. The App will then alert them to any issues and provide a full maintenance log and traceability.

These are just two examples of the ways that digital technologies and innovation can increase efficiency for both electrical contractors and their customers.

Those who fail to get trained on new digital products could find themselves working twice as hard as their competitors to achieve the same result. This enables electrical contractors to work smarter instead of harder.

Safer and simpler maintenance Safety is a key consideration for all those in the electrical industry. Being able to automate certain tasks, or flagging issues remotely, removes many of the risks that electrical contractors face on a daily basis.

Digitisation and connectivity of the electrical system also brings its benefits for the installed base, providing visibility of the system status (loading, alarms, location) at a device level, either locally or remotely via the App, allowing for a more focused call out for emergency/preventive and predictive maintenance. This is coupled with full traceability of the product. In additional full analytics,

packages may be added on top to provide dynamic monitoring of the system and recommendation, prolonging the life of the equipment and building a closer relationship with the end user.

deliver operational data in real-time, edge control to manage the process, and optimising as needed. Apps and analytics then provide the agility to allow users to make decisions faster.

Meeting customer demand Customers are increasingly aware of the latest technological innovations and, therefore, expect these to be offered to them at the very least. Being digital-smart means that you can fulfil the needs of your customers and lead the way in educating them on the vast benefits associated with smart or digital devices in the electrical industry.

An electrical contractor who is limited to installing simple wired-in solutions may not be meeting the current expectations of customers. However, a device that is constantly streaming data can offer them lots of useful, actionable insights in real-time – on factors such as energy consumption, equipment health, and faults.

By offering smart innovative solutions to customers, electrical professionals can transform businesses, saving installation time, energy and money. For example, a recent study showed that for machine builders, embracing IoT could mean drastically reducing their time-to-market by up to 50% as well as reducing their maintenance costs.

Solutions which incorporate Schneider Electric’s EcoStruxure can help professionals to deliver on the expectation of IoT for their customers. EcoStruxure encompasses connected products that

Getting up to speed It's not in question that digital transformation presents exciting opportunities for electrical contractors to reduce costs, save time, increase efficiency and safety. These don’t come without their challenges and pitfalls, however, especially for the less technologically savvy.

As with many industries, the pace of technological advancements means swiftly changing customer expectations as well as necessitating new skills in the electrical industry.

There is a prime opportunity for the next generation of electrical professionals to carve out a place for themselves in the industry, and offer real value to their teams at the same time.

Customers are looking for electrical advisors who can bring confident, individual recommendations for their specific needs, as well as digital solutions that enable superior monitoring and maintenance.

Meeting these ever-changing needs will be a prerequisite for success in the future of the electrical industry.

THE

CODEBREAKERS MIKE BOWLES: WHILE CARRYING OUT A VISUAL INSPECTION AT THE START OF AN EICR I FOUND THE ELECTRIC SHOWER SHOWN ON THE CONSUMER UNIT IN THE ENSUITE BATHROOM. IT WAS A 600MM SQUARE SHOWER CUBICLE WITH THE 45A DOUBLE POLE ISOLATOR INSIDE THE SHOWER CUBICLE. IT GOT BETTER – THE ELECTRIC SHOWER WAS AN 8.5KW UNIT, FED ON A 40A MCB, HOWEVER THE CABLE WAS ONLY 4MM TWIN & EARTH. NEEDLESS TO SAY I DECOMMISSIONED IT IMMEDIATELY. Sadly, poor and potentially unsafe installations can be found anywhere, not just in rental properties.

Whether the work has been carried out by unskilled labour or the owner, the outcome is still the same, and the tenant is at risk. There are a few things to cover here, so I’ll start with the isolator.

These are often situated close to the shower, and usually in Zone 2.

The thought process is that they should be used to switch the shower off after each use. This is not the intended use of these isolators, however, as they should be used for switching off for maintenance etc. The continual operation of them can lead to premature failure but the key here is that they're fitted in what appears to be a Zone, which they aren’t, as usually they're fitted on the ceiling.

Provided the body of the isolator doesn't protrude into the area of any zone’s height (which is 2.25m for either Zone 1 or 2 of a location containing a bath or shower, as defined by Part 701 in BS 7671) they're complying with Part 701.

Although this looks as if it wouldn’t comply with BS 7671, providing it is 2.25m above the finished floor level, we class it as outside of Zones, and therefore acceptable. It is the reason we allow this type of isolator and similar pull cord light switches in location 701. That said, I don’t recommend fitting an isolator in or above Zone 1. Claiming it is outside of a Zone, by its height, although technically allowable and compliant, borders on infringing good workmanship.

In this case, the ceiling is stepped, and by scaling the shower against the height of the soap tray, I would guess this isolator is now inside Zone 1, as it will not be 2.25m from the finished floor level, and therefore infringes BS 7671. As this is a special location, I would see this non-complaince as potentially dangerous.

Secondly, the supply cable being only 4.0mm2 twin and earth, it is unlikely to carry the full load current sufficiently without overheating and potentially causing a fire. The overheating may not take place straight away, as dependent on the incoming water temperature, time of year, duration of shower use, frequency of use, etc., the damage to the insulation may take a period of time.

It's nothing short of a ticking time bomb!

As we can’t see the supply cable, we can assume it's likely to be buried in a thermally insulating material, further reducing its ability to carry a sufficient current without sustaining thermal damage. It is likely that at least a 10.0mm2 twin and earth cable will be needed to comfortably deal with the loads and thermal issues, in this case.

The Observations, Regulation infringements and Codes applicable to this observation would be.

SEAN COOMBES: THE HEIGHT OF STUPIDITY – A 'FASTA FIX' BOX, HOLE CUT TO THE CORRECT SIZE, THEN PUT BEHIND THE PANEL! There are a couple of issues to look at here. Firstly, the dry lining box isn’t fitted or used as perhaps the manufacturer intended, which may have issues with fixing it in place.

All of the pressure will now be placed on the accessory to support the assembly, which it may not be designed for. While we look at the accessory screws, it seems as if they will be a problem to engage with the dry lining box, as the box is now not secure, making the second fix quite difficult and time-consuming.

Secondly, the exposed basic insulation is not taken into the dry lining box on the top surface. Where cables have exposed basic insulation, not taken into an enclosure, we only really have one way to go when we code, as it has a potential for further damage which may well prove to be dangerous.

Thirdly, as the box is fixed behind the surface the terminals are no longer contained within an enclosure and as the material appears to be flammable, there is an increased risk of the spread of fire in the case of a fault developing. These issues could also fall under the requirements for good workmanship and possibly not take account of the manufacturer’s instructions.

Although this is an easy fix, it could prove very time-consuming if there are multiple cases of this in the same installation.

The Observations, Regulation infringements and Codes applicable to this observation would be.

REPLACING A CONSUMER UNIT IN A DWELLING The team at NICEIC & ELECSA remind contractors of the importance of carrying out prework checks, when needing to establish the condition of the circuits before removing an existing consumer unit.

I

ssues can often arise during the replacement of a consumer unit without the condition of the existing circuits having been ďŹ rst assessed. A defect identiďŹ ed after the replacement has been made may prevent a circuit from being re-energised, often leading to conict with the person ordering the work (client). It is therefore essential that sufficient inspection and testing is carried out before work commences.

General It is important to establish the condition and functionality of the existing installation prior to undertaking the change or replacement of a consumer unit. For example, lighting controls may be switched to conďŹ rm their correct operation and, for socket-outlets, a proprietary ‘plug-in’ socket-tester could be used to check live polarity and conďŹ rm the number of socket-outlets connected to each circuit.

Wherever possible, any relevant information or documentation regarding previous inspections or issues with the electrical installation should be obtained from the user.

Note: Accessories installed externally, such as an outside light or a socket-outlet, should not be overlooked.

Installation earthing The installation should be reliably connected to a suitable means of earthing (Regulation 542.3.2).

An external earth fault loop impedance (Ze) test, as shown in Fig 1, should be undertaken to conďŹ rm the adequacy of the installation earthing and that the obtained value is appropriate for the type of earthing arrangement. For the purposes of the test, the installation should be isolated from the supply and the earthing conductor disconnected.

Note: All main earthing and bonding conductors disconnected for the test must be reconnected before the installation is re-energised.

fault conditions.

Maximum values of Zs for RCDs to BS EN 61008-1 and BS EN 61009-1 are given in Table 41.5 of BS 7671. However, for circuits not protected by an RCD, such as a distribution circuit, an earth fault loop impedance test should be conducted to conďŹ rm the relevant disconnection time will be achieved (Regulation 411.3.2.3 refers).

For an installation forming part of a TT system the requirements of Regulation 411.5.3 must be satisďŹ ed; that is, where an RCD is used for fault protection the disconnection time shall be that required

by Regulations 411.3.2.2 or 411.3.2.4 and đ?‘…đ??´ x đ??źÎ”n ≤ 50 đ?‘‰. Additionally, these conditions are deemed to be met where the earth fault loop impedance (Zs) meets the requirements of Table 41.5.

If the measured value of Ze is higher than that expected for a TN arrangement, this Note: Where a higher than expected wouldn not necessarily prevent the external impedance is measured the consumer unit replacement as long as the client should be advised to inform the relevant disconnection requirements of Distribution Network Operator (DNO).

Chapter 41 of BS 7671 are met for all circuits Fig 1: Ze test to verify the means of earthing (TN-C-S) reconnected (Regulation 411.3.2.2).

For ďŹ nal circuits protected by an 30 mA RCD, this higher value of external impedance should not compromise the rapid operation of such devices under kWh meter and additional PME earth electrodes omitted for clarity

TECHNICAL & TRAINING

Protective bonding conductors and circuit protective conductors (cpcs) The adequacy of the earthing and bonding arrangements should always be confirmed before any additions or alterations are made (Regulation 132.16 refers).

The ‘wander lead’ test method is typically used to confirm the presence of all circuit protective conductors. As illustrated in Fig 2, the test is performed with the consumer unit isolated and the main protective bonding conductors temporarily disconnected. One lead of the continuity test instrument is connected to the MET and the other test probe is connected, using a wander lead, to all relevant points, such as the earth terminals at ceiling roses or socket-outlets and the metallic fixing screws at switches.

Once the circuits have been connected to the new consumer unit, continuity of protective conductors should be re-confirmed and the readings obtained for each circuit should be recorded in the R2 column of the test schedule forming part of the EIC or DEIC. Note: For some accessories the fixing screw may not provide a connection to earth, so to perform the test the circuit should be isolated before removing the accessory cover.

Ring final circuits In addition to the ‘live’ polarity checks at socket-outlets described earlier, the continuity of the loop conductors should be verified to identify any high resistance or a break in continuity. To minimise any risks during the test, the whole consumer unit, rather than individual protective

devices, should be isolated before disconnecting conductors.

It may be preferable to split the ring and perform the test at a socket-outlet rather than the consumer unit.

Where a break in continuity or other issues are identified, such as underneath the floorboards, the remedial work involved could be significant, therefore the client should be made aware of the issue immediately.

Lighting circuits Lighting circuits in an older installation may not incorporate a cpc. Where this is the case, the client should be advised to have a cpc installed. If the client is not willing to have the work carried out, then they should be informed that reconnection of the lighting circuit is permitted only on condition that any metallic (Class I) light fittings and accessories are replaced with all insulated or Class II types.

A label should be affixed to the consumer unit stating that Class I equipment must not be connected to the lighting circuit. Details of the unearthed circuit should be recorded on the Electrical Installation Certificate (EIC or DEIC).

Another common issue relating to lighting circuits is the possibility of a shared ‘borrowed’ neutral conductor. The neutral conductors of each circuit must be electrically separate to prevent circuits being energised inadvertently (Regulation 521.8.2 refers).

Verifying that the neutral conductors are separate throughout the installation is achieved using an insulation resistance test instrument (refer to ‘Insulation resistance testing’).

Fig 2: Wander test lead to verify continuity of circuit protective conductors

24 February 2021 PROFESSIONAL ELECTRICIAN

Note: Where a shared neutral is identified, the circuit should not be re-connected. The client should be advised to have the necessary remedial

work carried out before replacing the existing consumer unit.

Insulation resistance testing If a low insulation resistance reading is obtained, this may be due to damage, the age of the cables, bad/loose connections or corrosion to connected equipment.

However, once reconnected to the new consumer unit such pre-existing defects may cause the operation of RCDs. For these reasons, insulation resistance testing should be carried out on all reconnected circuits.

Insulation resistance testing should preferably be carried out at 500 V DC between live conductors to Earth (with protective conductor(s) connected to the earthing arrangement). However, where there is a risk of damage to connected equipment the applied test voltage may be reduced to 250 V DC. Irrespective of which test voltage is applied, a value less than 1 MΩ should be investigated.

Location of the consumer unit The exact location of the replacement consumer unit and any necessary works should be carefully assessed and agreed with the client prior to its replacement. For example, it may be necessary for the replacement unit to be installed in a more accessible position to facilitate its operation (Regulation 132.12 refers).

However, the additional work involved in extending the circuits and routing them to the new position, even over a short distance, could be significant. For example, increasing the length of the meter tails is likely to require a separate device to be installed to satisfy the requirements for overcurrent protection.

Note: Although the height of the original consumer unit may not have complied with Approved Document M for England (similar requirements apply in other parts of the UK), any replacement will provide the opportunity to resolve such an issue.

Certification An EIC or DEIC should be issued to the client on completion (Regulation 644.1). To

box on the certificate to indicate that the work involves the replacement of a consumer unit. The replacement of a consumer unit in a dwelling in England and Wales is notifiable work and must be certificated for compliance with Part P of the Building Regulations.

Summary Some contractors have found that they're unable to re-energise a particular circuit after replacing a consumer unit because of an existing defect.

Whilst, for an existing installation it is impracticable to carry out all the tests that are required for initial verification, the level of inspection and testing undertaken for

QUESTION TIME: LIVE CONDUCTORS The technical team at NAPIT answer a common question that contractors raise.

t

his month's column will be based around a query we recently received. During an EICR, the individual in question came across two instances where bare or green and yellow circuit protective conductors had been used as live conductors: 1. The bare cpc in the PVC/PVC flat twin and earth cable had been used as a two way circuit.

PVC/PVC bare circuit protective conductors Such cpcs in thermoplastic insulated and sheathed flat cable have a reduced cross-sectional area compared to all sizes above 1 mm2. This is permitted under Regulation 543.1.1(i), that a cpc can be of reduced size if calculated under the adiabatic equation.

This would generally prevent the use of a reduced conductor csa for use as a live

2. The green and yellow conductor used in a multicore boiler control circuit had been used as a control circuit live, and oversleeved.

So, the million dollar question is: can these conductors be used as LIVE conductors?

There are two aspects to this question, so we'll split them as follows:

conductor such as switch-lines, strappers, neutrals and similar conductor applications (see Fig 1).

With regards to a neutral conductor, the requirements of Regulation 524.2.1 do not permit reduced csa and states that it shall not be less than the csa, of the line conductor for single-phase, and in three-phase circuits up to 16 mm2.

The other consideration of a bare cpc is that it is a non-insulated conductor, so

28 February 2021 PROFESSIONAL ELECTRICIAN

028_PE_FEB21_Layout 1 05/01/2021 12:02 Page 29

it’s use as a live conductor would result in a single insulated conductor being exposed. As such, single insulated conductors are required to be enclosed in a containment system like conduit and trunking.

Where a flat twin and earth cable are clipped direct/surface mounted, this would leave the cable having only basic protection for a live conductor. The potential for danger is compounded further if the cable is worked on, thinking the bare conductor is a cpc, when in fact it is live conductor.

Where future works are carried out, this non-compliant use of bare cpcs as live conductors can introduce unexpected hazards, where anyone coming into contact with a live protective conductor would receive a potentially lethal electric shock.

Multicore cables Where multicore cables, including flexible cables, have designated circuit protective conductors meeting the requirements of Regulation 411.3.1.1 and 514.4.2 having a combination of green and yellow bi-colour combination, they shall only be used as a protective conductor.

It is not permissible to over-sleeve a cpc for use as a live conductor to address the omission of an additional live conductor such as a boiler control cable, or to include a permanent feed for an emergency lighting circuit.

Obviously multicore cables without designated cpc can have one of the cores marked with green and yellow sleeving, as normally carried out in three core steel wire armour cables. The correct method for this is the selection of the black conductor as the cpc with green and yellow sleeving.

Mechanical protection Single insulated cables are considered to have basic or mechanical protection. Where a bare conductor, such as those in flat twin and earth, is over-sleeved, it is unlikely that the sleeving has an adequate mechanical protection rating, similar to that of a manufactured single insulated conductor.

Conclusion While BS 7671:2018 provides certain requirements for the identification of conductors, it doesn't permit the use of bare or green and yellow circuit protective conductors as live conductors.

One further consideration is BS 7629-1 cables which also have bare circuit protective conductors; the added danger should these be used as live conductors is the metal screen of the sheath would also become live, as the screen would be in contact with the incorrectly used bare cpc.

COMMISSIONING FIRE ALARMS Having recently launched its own fire systems commissioning service, ESP’s Managing Director, Neil Baldwin, provides a more detailed look at the area of commissioning, as outlined in the BS5839 standard documentation.

T

he process of commissioning involves thorough testing of the installed system to ensure that it operates correctly in accordance with the recommendations of this standard and with the purchasing specification.

At completion of commissioning, it also needs to be confirmed that all relevant documentation has been handed over to the user. The organisation responsible for commissioning the system might, or might not, be the same organisation that designed and/or installed the system, but the responsibility for commissioning needs to be clearly defined prior to the start of the installation work.

It is not, in general, the responsibility of the commissioning engineer to verify conformity of the design, or of the installation work, to this part of BS 5839 (i.e. with Section 2 and Section 4 of the standard). In general, the responsibility of the commissioning engineer is to verify that the system operates correctly in the manner designed and that the installation workmanship is generally of an adequate standard.

However, in practice, it might be difficult to ensure that the system complies in full with all recommendations of Section 2 until the time of commissioning. For example, commissioning might represent the first (and only) opportunity to determine whether the number and distribution of fire alarm sounders is sufficient to enable compliance with ‘clause 16.2’ in respect of sound pressure levels.

Similarly, commissioning presents an opportunity to ensure that structural features of the building, of which the designer might have been unaware, do not compromise the effectiveness of the system as it was originally designed.

Accordingly, it is necessary for anyone responsible for commissioning a fire detection and fire alarm system to possess at least a basic knowledge of fire alarm design practices and of the

PROFESSIONAL ELECTRICIAN February 2021 31

031_PE_FEB21_Layout 1 04/01/2021 16:03 Page 32

TECHNICAL & TRAINING

recommendations of Section 2 and Section 4 of the standard. It is also necessary for the commissioning engineer to be provided with the specification for the system.

In view of the importance now attached to the avoidance of false alarms, it is also essential that the commissioning engineer is able to verify compliance with, at least, the principles discussed in Section 3 of the standard.

Already offering a comprehensive range of fire protection systems for the professional electrical contract market, the launch of ESP’s new commissioning service means that all installed ESP systems operate correctly and are fully compliant with the latest BS5839 regulations.

This latest development means that ESP now offers a full fire alarms systems package, with access to a free design service, a vast choice of products including the latest two-wire systems, the new commissioning service, plus technical

support from a team of qualified and experienced engineers.

More to it than meets the eye There is much more to commissioning a fire protection system than simply turning it on and setting detector addresses. It involves going through a comprehensive step-by-step checklist to ensure full compliance with the correct British Standard and carrying out a range of tests to ensure reliable and trouble-free operation.

ESP’s new commissioning service will ensure that a qualified engineer will confirm that the system has reached the relevant British Standard, and they will issue a certificate on completion of the project prior to system handover.

Dedicated ESP commissioning engineers are located throughout the UK to provide wide-reaching access to this new service.

ESP has been developing and supplying fire and security related

products to the UK electrical industry via the wholesale channel for more than 20 years. The company has continued to grow its MAGfire Fire Protection category and today offers a range of products and systems that covers conventional, addressable and the latest two-wire fire alarm system range.

The fire protection product range is divided into three categories: 1) the MAGDUO two-wire fire alarm system, which offers small/medium contractors a highly flexible and adaptable system, 2) the MAGfire conventional, or four-wire, fire alarm systems – traditionally used in smaller properties, such as shops, and 3) the MAGfire addressable systems – suitable for large, commercial premises and more complex networked systems.

lthough the EV tester market is getting more crowded,” comments Brendan Beaver, Metrel UK's Manager, "it's worth remembering that Metrel multifunction testers will guide you through the process to make sure all the required tests are performed and the installation is satisfactory. And all this for the cost of an ordinary multi-function tester.

“Our recently announced EV contractor kit takes advantage of the modern dot matrix screens on Metrel multifunction testers to not only display the results of tests but to guide you through those tests at the same time.

“Once initiated the EVSE Autosequence tests lead you through both the functional and electrical tests required to certify the installation. That's great news for beginners as well as providing faster results for experts.”

He concludes: “The results can then be saved on board, and any comments made using the qwerty keypad. The accompanying software certainly makes certification a breeze.”

SURGE PROTECTION FOR SOLAR INSTALLATIONS Amendment 2 has provided a number of proposed changes around surge protection, with significant changes to section 712 which discusses the regulations surrounding solar photovoltaic (PV) power supply systems. Kirsty Johnson, Technical Sales Director at Surge Protection Devices, looks at how these might work.

N

ew regulation 712.443.101 states that where protection against transient overvoltage is required by section 443, such protection shall also be applied to the DC side of the PV installation. So, if for example, the solar installation is on the roof of an industrial building where the regulations in section 443 require SPDs to be installed, SPDs would now also need to be installed on the DC side of the installation to protect both the PV panels and the inverter.

When a PV system is installed within the protected volume of the LPS system, the PV system should be separated from all parts of the LPS in accordance with BSEN 62305-3, which describes the calculation for the correct separation distance. If the separation distance isn't met, then to BSEN 62305 a Type 1 device will be needed to protect the installation from the effects of lightning.

All SPDs installed on the DC Fig 1 side of a PV installation shall comply with BSEN 61643-31.

When the inverter incorporates an SPD, it's only considered as fulďŹ lling the SPD requirement if the manufacturer speciďŹ es its use for the DC side of the PV installation, otherwise it will need Fig 2 an external SPD. Varistors included in the inverter aren't considered an SPD. Generally, the SPD will be a Type 2, unless the building has an external lightning protection system. If the LPS doesn't have the correct separation distance according to BSEN 62305-3, a Type 1 device will be required.

On selection of the SPD for the PV system, care must be taken to ensure that the following guidelines are met: l The Up of the SPD must not exceed the Uw of the equipment to be protected (if

you don't have this information, table 712.1 in BS7671 will provide average ratings) l The Ucpv should be greater than or equal to the Uoc max of the PV array l Type 2 SPDs should have a minimum In of 5kA l Type 1 SPDs Should have a minimum Iimp of 12.5kA

034_PE_FEB21_Layout 1 05/01/2021 12:06 Page 35

Fig 3

Where the inverter is located more than 10m away from the origin of the installation, an SPD shall be installed near the inverter, in addition to the SPD at the origin of the installation. The type of device will depend on the installation. The illustration in Fig 2 will help to determine what is required.

SPDs on the DC side shall be located as close as possible to the inverter, and to provide protection additional SPDs may

be required further from the inverter.

Fig 3 is recreated from BS IEC 61643-32. It details the locations required for SPDs on a PV installation.

AC side: The SPD at location 3 is the main incomer, which is required under BS 7671, section 443 or BSEN 62305, if an LPS system in present. If the SPD at location 3 is more than 10m from the PV inverter, an additional SPD should be installed at location 2. The type of this device can be decided using Fig 2.

DC side: If an SPD is located at location 3, then a DC SPD is required at location 1. The type can be decided using Fig 1. If the PV

array is located more than 10m away from the SPD at location 1, an additional SPD can be installed at location 4 to provide local protection for the PV array.

Obviously, at the time of writing we're working with the 'proposed' changes and there is a chance that some elements may have changed slightly by publication.

We're currently expecting publication of Amendment 2 in March 2022, which we all know will be here before we know it!

AM2 - KNOW THE FACTS

National Electrotechnical Training (NET), the organisation responsible for the AM2 assessment, addresses some industry misconceptions and offers advice on the new AM2E.

T

he AM2 assessment of competence has been around for nearly 40 years. As time has progressed, the assessment has been adapted to reflect changing industry practices and requirements, but it has remained the gateway to fully qualified electrician status, with recognition via an ECS gold card.

NET is responsible for developing and managing the suite of AM2 assessments, along with assessments in related specialist sectors such as fire and security, network cabling and building energy management systems.

A number of misconceptions have been circulating about the AM2, AM2S and AM2E, particularly following the launch of the Experienced Worker Assessment, which has the AM2E as a key component. So NET is taking the opportunity to clarify a number of issues surrounding some of the most common questions.

Why do the names differ – what does each assessment entail?

The assessment itself is very similar; the different letters at the end are

primarily for external reporting and monitoring purposes.

The AM2 is the most commonly known assessment. It is taken by apprentices who follow an ‘Apprenticeship Framework’ in England, Wales and Northern Ireland (in England, the framework has now been replaced by the ‘Apprenticeship Standard’). It’s also the assessment for those registered on the JIB Mature Candidate Assessment or completing the industry Level 3 NVQs. The AM2S is solely for apprentices who are on the English ‘Apprenticeship Standard’. It contains the same tasks as the AM2, plus the addition of containment installation. The section names and lettering also differ between AM2 and AM2S. The AM2E mirrors the AM2S, however it can only be taken by individuals who are registered on the Experienced Worker Assessment.

What is the Experienced Worker Assessment?

The EWA was launched in summer 2020

by The Electrotechnical Skills Partnership.

It’s a new way of helping those with years

of experience who, for various reasons may not have completed their apprenticeship or qualifications in the past, complete a robust assessment and work portfolio process in order to gain industry accreditation and an ECS gold card.

In order to promote a common industry standard, the EWA has been designed to mirror the industry apprenticeship.

Anyone holding non-UK qualifications wishing to achieve ECS gold card recognition will also need to complete the EWA. If I hold AM2 already and I do the Experienced Worker Assessment, will I still need to take the AM2E? The core principle of the EWA is that you should have full account taken of your experience, and not have to jump through hoops unnecessarily and pay out for re-assessment that isn't required. That’s why we've looked carefully at how we can acknowledge and recognise those who already hold an AM2 certificate.

If you've passed the AM2, you'll not need to take the full AM2E, but you will need to complete a supplementary unit at a NET centre. For AM2 taken before April

PROFESSIONAL ELECTRICIAN February 2021 37

037_PE_FEB21_Layout 1 04/01/2021 19:14 Page 38

TECHNICAL & TRAINING

2010, you'll need to complete a unit that covers testing; for AM2 taken after April 2010, you'll need to complete a unit covering the installation of containment.

Our clear advice to anyone who already holds AM2, regardless of its age, is to contact TESP via its website – www.the-esp.org.uk/contact – with your details, before registering on the EWA. We'll consider each candidate’s specific

circumstances to look at their qualifications and experience and give independent advice to ensure the EWA is the appropriate route.

As the industry’s skills partnership, TESP has no commercial interests and so can give unbiased advice on your position before you consider a training provider for the EWA, or an alternative route.

What about other older qualifications?

Again, we recommend that you contact TESP to outline your personal situation so we can advise accordingly. If gaining an ECS card is your specific intention, you could also visit the ECS card website as

there are specific requirements on the eligibility of different qualifications.

Overall we’ve been very pleased with the level of interest in the EWA since its launch. We're committed to ensuring it offers a robust route to full qualification, whilst recognising the existing qualifications and experience of candidates. In order to create a truly worthwhile process that benefits you and your previous achievements, it’s important we take this tailored approach.

Prior Preparation…

NET is a registered charity, so we're not in the business of wanting to profit from assessments. It’s in our (and the industry’s) interest to improve the pass rate and minimise re-takes.

To support this aim, NET has produced a number of free resources to help those preparing for their assessment. Our ‘Readiness for Assessment’ Checklists map out clearly what you'll need to do in each section of the assessment. Use this

037_PE_FEB21_Layout 1 04/01/2021 19:15 Page 39

WORKING FOR THE GOOD OF THE WIDER INDUSTRY

as your bible and also look honestly at what areas you’ll need to brush up on.

The AM2 tests a broad range of practical skills and knowledge; if you’ve been working in niche areas for a number of years you may need to put additional preparation work into some sections of the assessment.

On our website we also have resources such as Top Tips videos and a Pre-Assessment Manual – use these to your advantage! It’s surprising how many candidates still fail on basic errors such as not reading or following the specification.

Knowledge is power For those looking to take any AM2 assessment we encourage you to look directly on the NET website for all resources – including the checklists – to ensure you're using the most up-to-date versions.

We also urge people to reference the NET and TESP websites for regular updates regarding the AM2E assessment and the Experienced Worker Assessment respectively.

Make sure you're armed with all the facts so you can make an informed choice about how to move forward.

Many people don’t know that in addition to its role as guardian of the AM2 and other assessments, NET’s charitable work also includes promotion of the industry elsewhere and encouraging people into electrotechnical roles following the correct training routes.

Each year NET organises the SkillELECTRIC competition and is a member of TESP, through which NET has helped to fund the Electrical Careers website and extensive labour market research. In the pipeline for NET this year are more videos and resources to help people prepare for their assessment, along with a new ‘Future Faradays’ college engagement project.

As the brand celebrates its first anniversary since launch, the team at Ovia explains why there is no dimming the bright future that lies ahead for the company.

ONE, BUT FAR FROM DONE!

A

year since its official launch, has Ovia delivered on its promise to offer a broad range of high-quality, competitively-priced lighting products that offer an abundance of features and speed of installation as standard? The answer is a resounding ‘yes’, according to feedback from installers.

When Ovia was launched as an independent lighting organisation a year ago, the company’s aim was to fill a gap for a broad spectrum of entry level lighting products that are competitively priced, packed full of features and benefits, and are quick and easy to install to help contractors save time and money.

A year later, and despite the major challenges faced in the prevailing climate, Ovia has kept on track with its ambitious plans, exceeding expectations for the first year of trading independently.

There has been investment in new products and in state-of-the-art testing equipment, the addition of new team

members, and the launch of the 2nd issue of the Ovia catalogue. The comprehensive Ovia range now includes products that cover a wide range of applications and include domestic, amenity, commercial, industrial, utility, floodlighting, and emergency lighting.

created by the LIA, together with its partner Acal BFi, to enable lighting manufacturers to offer efficient third-party certified luminaire performance testing.

By bringing the light test facility in-house, the ground-breaking testing scheme is radically speeding up the

Investment, innovation Ovia has made some significant investments in the last 12 months. These include the purchase of cutting edge testing equipment and a revolutionary photometry testing scheme, the appointment of a former BSI testing expert and the addition of new products to its growing lighting and lighting controls ranges.

The company purchased its own Goniophotometer device and signed up to the revolutionary Gonio photometry luminaire testing scheme which has been

testing process for Ovia’s lighting products and also offers reassurance when it comes to validating photometric measurements such as Lumens per Watt and related performance claims.

New products and a bumper catalogue Phase 2 of Ovia’s product development programme aims to build on the success of the first phase. When we started out a year ago, we had the domestic market well covered with the products we offered. Our expansion into other sectors was always the aim and we've had some great success, particularly with our commercial and floodlighting products.

At 328 pages, the new Ovia Lighting Catalogue issue 2 is twice the size of the previous version and brings to installers a comprehensive product guide covering the entire range on offer.

It includes new and improved products that have been brought to market on the back of continual engagement with contractors to ensure that the products and solutions they seek are developed and available through the wholesaler.

Some of the products that have got installers talking include: Inceptor Intense LED Strips: a range of IP20 and IP65 rated, 24V LED strips, available in cool white, warm white and RGBW. Inceptor B-Lite: a range of 4, 5 and 6ft linear batten multi-current LED fittings, available in standard, microwave sensor, emergency, and combined microwave and emergency sensor versions. They're a

direct replacement for conventional battens and boast many features. The multi-current driver, with the option for four different wattages, allows the installer to increase or decrease the lumens, depending on the requirements for each individual application. The fitting is combined in single output and twin outputs, so there's no need for two separate units.

Inceptor Slate Backlit: a range of TP (b), TP(a) and TP (a) UGR19 rated backlit panel fittings, with an option that utilises UGR diffuser with a TP(a) thermoplastic rating, making them suitable for all working environments. They're available in three colour temperatures and supplied with a pre-wired, push-fit Pole Flow connector for quick and easy installation.

Free lighting design service As part of a commitment to deliver a first class service, a dedicated Ovia lighting design service is available, giving contractors access to free lighting design schemes for their commercial projects.

The aim of the service is to provide expertise in choosing the right products and solutions to create a scheme that meets all the requirements and objectives of the project in question, and

42 February 2021 PROFESSIONAL ELECTRICIAN

is compliant with all the relevant regulations and standards.

The future is bright Commenting on Ovia’s first year, Sales Director, Mike Collins, said: “It's been an extremely challenging but rewarding 12 months as we continue to grow the Ovia lighting range.

“Regular engagement with contractors is how, as a group, we gain constructive insight into how they like to work, the issues they face and what they need to help them do their work in the most time-efficient and cost-effective way. Whilst we may not have been able to meet contractors at many of the usual trade shows in the last 12 months, we've continued to engage with them via social media, trade magazines and our own SGTV YouTube channel.

“It's the valuable feedback we get from them working on the job – often in challenging environments – that helps to drive the new product development programme. We look forward to continuing this interaction with them throughout 2021.”

USB DEVICES: IS THE FUTURE 'A' OR 'C'?

Gavin Williams, Sales & Marketing Director at Hamilton Litestat, discusses what new EU regulations around USB charging devices will mean for the contractor and how some of the latest solutions can keep customers ahead of the curve.

T

he demand for faster charging of devices has led us to new USB standards, and with it an increased requirement for fitting sockets with USB charging capabilities. However, popularity is now set to rocket because of changing EU regulations. In a move to reduce electrical waste, battery-powered devices will no longer include a standard white block plug-in charger.

We all have those drawers full of odds and ends, and one item that’s sure to have a home there is the block plug-in USB charger. Until now, they’ve come as standard with battery devices that need charging, so in fact most people normally have a lot more than one laying around.

Eventually, when the drawer gets full, they end up as e-waste.

In a move to reduce the impact on the environment the European Union is trying to stop manufacturers from providing one of these with every device and move towards a standard USB-type charging connector instead. One of the first brands

to make this change is Apple, which won’t be providing a charging unit with the recently revealed iPhone 12.

But what does this mean for customers and contractors? An increased demand for USB charging ports is anticipated, both for commercial and residential properties. But not all USB connectors were created equal – there are both USB Type A and USB Type C ports – so what’s the difference?

USB-A vs USB-C We may think we know the USB connector as most electronic devices such as laptops and computers will have a USB port, but more specifically this is USB Type A, or USB-A as it’s increasingly being known. This has a reasonably large physical connector and can only be inserted into a port in one orientation. This requires a USB 2.0 connection for charging, which offers up to 2.5W and will charge your smart phone overnight at a reasonably slow and steady pace.

However, a new standard that enables significantly faster charging is on the

44 February 2021 PROFESSIONAL ELECTRICIAN

horizon – the USB Type C, or USB-C. Unlike USB-A, USB-C has the same connector pins on either side, so can be inserted into a charging point either way up and is physically much smaller than the USB-A variety.

More importantly, it supports new USB standards, such as USB 3.1 and USB PD (Power Delivery). USB 3.1 facilitates extremely fast data transfer of up to 10 Gbps, while USB PD enables power transfer of 100W for rapid charging. Not only can a device receive this increased power, but as it’s bidirectional it can also send power, too.

Unlike the early days of mobile phones where each brand had its own unique charging cable, USB-C is set to become standard across new technologies. As mentioned, Apple has done away with the charging block and adopted the USB-C standard for its upcoming products, as have more than 700 technology companies including Dell, Google, HP, Intel, Microsoft, and Samsung.

044_PE_FEB21_Layout 1 04/01/2021 16:23 Page 68

Charging ahead To meet the demand of the new standard while also supporting the charging of legacy devices, companies manufacturing electrical wiring accessories, such as Hamilton Litestat, are producing sockets with combined USB-A and USB-C charging ports.

These allow existing devices to be charged, but ensure functionality is pre-emptively installed for the next wave in technological development. And it’s these solutions that provide a business opportunity for today’s electrician to stay ahead of demand.

Hamilton’s USB ports are clearly labelled with the rated current or rated power values, as per BS EN 62368 Annex F (Markings). Tests also confirmed that there's no issue with power sharing between sockets when charging: if two devices are plugged in then they're both getting the correct and equal charge, rather than one taking additional power. However, currently (and with no pun intended) there are restrictions on the charging capability from a 13A socket. Faster charging needs more power, more rapidly.

To enable this, a larger charging module is required on the back on the socket. At present, this isn't possible due to the unit needing to be packaged within the

restrictions of the standard 47mm deep back box. But as USB-C becomes standard, USB-A ports will become redundant and this will free up space in the unit for larger charging modules that can deliver the power USB-C is capable of receiving.

Power up In the meantime, it’s possible to install a Euro Module that will deliver a higher rate of charge. Hamilton has recently launched a 45W Type C / 18W Type A Euro Module. This isn't a 13A socket outlet, but a combination plate designed to deliver additional power that can support higher capacity devices.

It is a standard 50 x 50 unit and is ideal for charging high performance devices, such as the new MacBook Pro. Offering both USB standards, when a device is plugged into the Euro Module it will negotiate the power output with the charger. For instance, if it’s plugged into the Type C port then it will accept the full 45W on offer, or will let the charger know if it requires less. The current and the voltage will adjust to enable optimum charging.

The same applies to the 18W Type A socket, however, for the benefit of customers, Hamilton has adopted different labelling on this device. Instead of communicating the current and voltage, it aligns the labels with the device

manufacturer protocols. The USB-C is labelled with PD (Power Delivery) and the USB-A with QC (Quick Charge).

A thirsty device that benefits from the Euro Module is the iPad Pro. When plugged into a USB-C port in a standard 13A socket, the iPad Pro is effectively on trickle charge – it’s not able to get the power required for a proper charge as the socket isn't fit for this purpose. However, when plugged into the Euro Module it can increase its charge and power up effectively.

For contractors looking to offer future-proof wiring accessories to their clients, Hamilton’s USB charging products provide transitional solutions. Its sockets with both USB-A and USB-C ports provide charging to new and legacy devices, while the Euro Module delivers the additional current and voltage required of more power-hungry devices.

With devices determining the charge accepted, the power provided by these ports will automatically increase as the device’s capability improves, ensuring customers are set for the next charging standard.

MAKE SOME 'SMART' MOVES

S

mart technology in the home has been a hot topic for a number of years now, yet does the hype match the reality? Are householders adopting smart technology in droves, creating connected homes that can be controlled either by a phone App or smart speaker?

According to recent research by techUK, an organisation that promotes technology advancement and adoption, the answer is ‘not really’ or perhaps ‘not fully’.

One finding from the research really underlines where we're currently at with the adoption and utilisation of smart devices – despite the strong growth of smart speakers over the last few years (7% ownership in 2017, to 29% in 2020), when it comes to using smart speakers to control other devices at home, less than half of owners are doing this.

Instead, they're more likely to ask Alexa to play music, give them the news or weather, or tell a joke, than to switch on the lights or turn down the thermostat. The connection has not been made, literally.

Of course, early adopters are probably using smart speakers to do a whole host of things, but the fact remains that for

The adoption of smart technology in the home is increasing, but it doesn’t have to be overly complex. Scott Brewer, Head of Technical at Knightsbridge, explains why.

many the approach to ‘smart’ is inconsistent, not joined up or they fail to see the benefits.

But ‘smart’ doesn’t have to be complicated and can offer the enterprising installer the opportunity to ‘sell’ up. If you can create a simple-to-use smart system that offers convenience, flexibility and scalability for your customer, then that’s got to be good for business. And that’s where our latest range of Knightsbridge smart products comes in.

configured into the SmartKnight App, the wiring accessories and lighting products can be controlled via a smartphone. All your customer has to do is download the App to their smartphone from either Google Play or the Apple App store and follow the instructions.

One thing that's worth noting is that the entire smart product range has been sent to Google and Amazon for independent testing and approval beforehand. That's why you’ll see the official 'works with' logo, rather than ‘compatible with', which some systems will use.

be able to take advantage of all the useful features of the App, such as timers, schedules, scenes, and geo-fencing (so devices can activate when the customer gets home). And what could be more convenient than issuing instructions to either Alexa or Google Assistant to turn down lights or turn off connected appliances?

At the heart of the Knightsbridge smart home portfolio are the two 13A, 2-gang, smart switched sockets, manufactured to match the designs of the existing square and curved edge range of moulded switches and sockets.

These feature a power monitoring function so that the homeowner can see live power usage on the socket in kWh and a green indicator on the socket shows if the relevant gang is on. Appliances attached to the socket will be controllable remotely or by voice. For outdoor use there's an IP66, 2-gang switched socket, that works up to 40m from the house, depending on Wi-Fi signal coverage.

Fun options available Where your customer will have most fun is with the range of smart LED downlights which can be controlled via the SmartKnight App to provide a raft of lighting scenarios.

Depending on the model installed, they can vary not only the colour temperature from warm white to daylight and everything in between but also the RGB colour with over 16 million options available.

The range also features a number of useful ancillaries to extend the smart capability of the home, such as a 16A smart plug, a 10A 3-gang smart extension lead with quad USB charger, and smart motion and entry sensors.

Whatever your customer’s appetite for ‘smart’ may be, the Knightsbridge range can help to satisfy it. But remember, don’t just sell product, sell smart – it’ll pay dividends in the long run.

Miguel Aguado, Marketing & Technology Manager, and Steve Detmer, Residential Product Manager, both at Lutron Electronics, answer questions about the lighting trends that are set to shine in 2021.

FLEXIBLE WILL BE YOUR FRIEND Q. WHAT HAS THE COMMERCIAL LIGHTING INDUSTRY LEARNT FROM LAST YEAR?

MA

The challenges of 2020 have taught us that the way we use our buildings can change rapidly. Offices, hotels and leisure facilities have been most affected by the constant shifting of regulations and with this uncertainty set to continue into this year, it's no longer possible, or wise, to prescribe a rigid lighting solution. This year we can expect major investment in solutions that empower and support the ever-changing use of our buildings, and a pull away from limiting, prescriptive systems that have been detrimental to building managers so far.

SD

Within the commercial space, the past year has proven to many employers that a remote working model can be just as effective as an office-based one. So, to warrant continued investment in an office space, facilities managers will need to ensure that their offices offer benefits that

employees can’t get from home.

Enhancing collaboration, productivity and well-being will be the main objectives of workspace design in 2021.

Q. HOW CAN LIGHTING HELP FACILITATE THE RETURN TO THE OFFICE IN 2021?

MA

The growing demand for this flexibility and adaptability can be met by the adoption of wireless technology. When returning to the office, many employers will be looking to employ temporary partitions or reconfigure space usage to meet social distancing guidelines. Wireless sensors and controls can be easily moved to facilitate these adaptations as they happen, taking minimal time to install and avoiding inconvenient and disruptive rewiring.

These solutions also help to achieve a more ‘contactless’ occupant experience.

Using sensors instead of light switches avoids cross-contamination, giving employees peace of mind. Wireless systems can also further enhance user comfort and reduce risk through the

application of personal controls, allowing occupants to modify their desk space or change the lighting in a room to optimise their environment for their current task.

Managers of communal spaces will continue to be under pressure to be COVID-safe, and to future-proof for other possible disruptions as we’ve seen this year. Swapping hot-transmission spots, such as traditional light switches for ‘contactless’ solutions, will be a priority for office managers as employees return to the workplace.

Colour-tuning is an exciting lighting trend that is yet to see wide adoption in the office setting. This is a great solution to enhance well-being and productivity by giving occupants the ability to tune light – both natural and artificial – to suit their individual needs. Going forward, we can expect to see application of personalised colour-tuning in a bid to enhance occupant well-being, and offer an enhanced experience that employees can't get from the home-office.

Q. WHAT TRENDS/CHALLENGES DO YOU EXPECT TO SEE IN THE RESIDENTIAL SECTOR THIS YEAR?

SD

2020 re-defined our expectations of our homes and of technology, and these new parameters will set the tone for this coming year. In the residential sector, investment in lighting has already seen a boom that we expect to continue into 2021. The demand for smart home technology will continue to rise, especially as the office and the home converge. The benefits of smart lighting, such as energy savings, improved aesthetic and enhanced comfort will be the main consumer demands of lighting suppliers.

With demand also comes innovation.

Therefore, in 2021, we can expect LED performance to take great strides as the industry learns more and prices come

down, creating more accessible and widely adopted smart-home options. For residential customers, user experience will be a key driver of demand for lighting design and solutions for the coming year.

MA

Whilst these considerations and investments in occupant wellbeing are commonplace in commercial spaces, the home office doesn't beneďŹ t from the same attention. Many may feel more comfortable working at home, but with no guidelines on lighting levels, air quality or

posture support in the home, how can employee output and experience be optimised?

With widespread, long-term adoption of hybrid working expected to continue this year a renewed focus on optimising the home office will be needed by both employees and employers alike, in order to support productivity and employee wellbeing.

LIGHTING THE RETURN TO WORK

t

here's no denying that the commercial property sector is undergoing a period of change as a result of the coronavirus pandemic. However, the death of the office shouldn't be exaggerated.

Whilst employees’ working habits are changing, they still have a strong desire to spend time in the office. This idea is supported by the latest data from the British Council for Offices (BCO). It shows almost half of workers – 46% – intend on splitting their time between their home and the office.

There's no clear roadmap for welcoming employees back, and the challenges of returning to the office faced by larger corporations and small businesses will differ. Yet both are certain to face reduced occupancy levels.

Business owners and building managers will be keen to create pleasant office spaces that encourage people back into the workplace. As a result, there will be greater expectations about the working environment and the building systems that serve them.

Lighting remains one of the most fundamental of these; whether it's a large office complex or small business studio, having the correct light will make a big difference to employees. From an electrician’s perspective, there's a clear opportunity to talk to your customers

Colin Lawson, Tamlite Lighting’s Head of Market Intelligence, explores how smarter lighting can help meet the changing needs of the workplace.

about how you can help them prepare for the ‘new’ normal, and create comfortable, productive and safe office environments.

will ensure that the lights aren't used when the room is unoccupied by dimming or switching off the fittings.

Here’s a few ways that lighting can make a difference:

Make the most of natural light Natural light is the most important type in any office. Daylight dimming reduces the output of the luminaires when natural light levels increase. Not only does this ensure that lights are only used when they're required but also provides a more organic lighting design. This ensures that energy isn't wasted, providing significant long-term energy savings.

Make the switch Sadly, not all businesses are yet aware of the benefits of LED lighting. So there's an important opportunity to steer companies towards replacing outdated fluorescent lighting with the latest LED-based solutions. This will help eliminate glare and improve comfort in the office.

Health and wellbeing Businesses are increasingly looking at how they can enhance their workspace for the benefit of employees. Offices designed with a more ‘human-centric’ approach to lighting can make them healthier, safer and happier places. Installing lighting that can be tuned to work in harmony with workers can help improve their overall wellbeing by reducing stress and anxiety, increasing productivity and profitability.

Take control With fewer people using the office space available, businesses will want to make sure that lighting is only used when it's needed. Lighting control systems add a level of flexibility that is vital in modern offices. For example, installing PIR sensors

50 February 2021 PROFESSIONAL ELECTRICIAN

Saving energy Installing controls and sensors will allow businesses to make informed decisions about how their office space is being used, and make changes to lighting schedules and settings. This can dramatically reduce energy consumption, as the lights are only on when needed.

Re-thinking how we talk about light to our customers is key, and it’s not as complicated as it seems. With an ever-growing focus on improving the office-based worker experience, the needs of end-users in this area can be achieved through the power of smarter lighting.

Products IN PRACTICE

CP Electronics delivers at Daily Express Building CP Electronics has supplied its RAPID lighting controls system to the iconic Daily Express Building in Great Ancoats Street, Manchester as part of a recent refurbishment project.

Working with contractors CSK Electrical, CP Electronics supplied its RAPID fully addressable system with daylight compensation which had to be carefully planned due to certain containment and wiring routes within the building.

The light fittings could contain up to three LED sections all requiring independent control which was achieved using area controllers and DALIG64’s. With little room for cable management above ceilings, CP Electronics’ BVITM6 lighting control modules were used as a marshalling box providing CSK with a local isolation point whilst still being able to control each independent unit as required.

With the lighting mounted into plasterboard ceilings as opposed to recessed fixings, this presented the challenge of PIR sensitivity. In order to overcome this, CP Electronics suggested using its EBR-MINPIR-DALI Mini. This presence detector detects movement using a PIR sensor to turn the load on.

When an area is no longer occupied the load will switch off after an adjustable time-out period. The compact size together with multiple mounting options make this product ideal for mounting in, or attaching to, luminaires to provide local control of individual fittings.

An adjustable internal light sensor provides light level information to the lighting control system, allowing lights to be

52 February 2021 PROFESSIONAL ELECTRICIAN

kept off if sufficient daylight is present, and to enable maintained illuminance for dimming systems. For this project, the EBR-MINIPIR-DALI could be installed in the small panel between each LED section, which also meant that no extra cabling to the PIR was required as they could be connected onto the DALI Bus already present in the light fitting.

Reconfiguration of rooms within the building meant that local switching combined with absence detection was required. To achieve this CP Electronics suggested using its EBR-BB-IN-DALI which meant the interface could be connected to the DALI Bus and control the lighting without the need for extra wiring.

The EBR-BB-IN-DALI input unit is the perfect interface between a RAPID lighting control system and external devices such as switches, security systems and AV equipment. The unit features seven volt-free switch inputs that can be activated by the contact closure of push-buttons, switches or relays.

The lift lobby floor area lighting wasn't dimmable but required interfacing with CP Electronics’ control system. The perfect solution for this was to use the volt-free relay within the DALIG64 that allowed for the lights to be turned off and on using the presence detectors already installed on the floor. The staircase and WC areas weren't required to be fully addressable so standalone 230V presence detectors were installed.

ESP FUNERAL SERVICES PROVIDER When the UK’s leading funeral-related services provider found that it badly needed renovation of one of its largest premises was suddenly put on hold due to the unavailability of products and staff, ESP was able to come to the rescue to provide the fire protection and emergency lighting products required to complete the project. ESP was initially called on to provide a quote for a range of products that had already been specified for the project. However, having looked at the plans and identified some issues due to the nature of the concrete building, the ESP design team were able to work with the installer to come up with some alternative products and solutions that would work better. The MAGfire addressable 16-zone fire panels, smoke detectors, sounders and call points, as well as the Duceri emergency twinspots and bulkheads, were all recommended. Whilst competitive pricing and speed of delivery were significant factors in helping ESP to secure the project, a key element was ESP’s ability to offer the requisite fire training.

Installation is as easy as securing the simple ‘H’ design mounting bracket to the wall with four screws, lifting the unit onto the supports and locking it securely in place. For future redecoration the unit is simply unlocked and tilted forward to gain access to the wall behind.

CAUGHT ON

C A M E R A SOCIAL SNAPS! KAREN BOOM: Please tell me you're joking?! Seriously, this is what the customer was expecting me to terminate into.

ANDY LLEWELLYN: Not the most professional job I’ve ever come across!

OLES: The customer wanted the boiler wired in, but didn't want me to see the consumer unit. I wonder why?

BARRY MAY: Upgraded a consumer unit and was astonished to find out that at least five years ago the previous electrician had managed to bypass the faulty main switch!

NICK BLAKELEY: This cable joint had been plastered over in a ceiling that got wet following a roof leak. Lucky, very lucky!

MARTIN WELSH: The customer requested that the DB be upgraded to match the new DB that had been installed for the storage heating.

ADAM BROWNETT: This was found in a three-year-old garage conversion!

LAURIE POWELL: A classic install from our kitchen fitter friends!
