Editor’s Viewpoint

The ‘Net’ has widened At the time of writing, we’re pretty confident the Prime Minister, Rishi Sunak, will have his hands full dealing with the fall-out from the announcement that the northern leg of the HS2 development – which would have seen the route terminating in Manchester – has been scrapped. Although the development has been under serious scrutiny, due to the rising costs and disruption to the countryside/landscape, the government, until now, had been staunch in its position that the original proposals and aims for HS2 would remain untouched. Of course, there will be outrage and much comment in the aftermath, and many will point to the short term approach that government has taken by simply pulling up the drawbridge. That said, the PM has faced increasing criticism in recent times about the government’s lack of proactive action and measures that could divert funding for such a project into areas where the need is greater. Although HS2 will dominate the majority of headlines, just a few weeks previous the PM had shown that this regime is not afraid to ‘pivot’ or readjust its targets after revealing that there will be exemptions and delays to several of the original 2030 and 2050 ‘Net Zero’ strategy targets that the country had vowed to achieve. Despite the initial outcry prior to the PM’s announcement, the revised targets have been met with a realistic response from those representing the interests of the electrical industry – a sector which, after all, will play as big a role as any in helping to achieve a greener and cleaner environment. Clearly future business confidence and investment is going to rely on a consistent approach by governments, with ECA warning against the temptation for the respective parties to use the Net Zero targets as some sort of political football and to ensure the focus isn’t taken away from developing the pipeline of professionals that will have the skills to deal with new technologies and concepts. Paul Reeve, ECA’s Director of CSR, commented: “Rishi Sunak’s overall direction of travel towards achieving Net Zero has not changed. But a delay in the timescale will undoubtedly shake the confidence and

plans of many large and small businesses alike, not to mention consumers. “The new timetable gives more time to decarbonise and develop the UK grid. Instead of focusing on one or two low carbon fixes, it’s an opportunity to move to a ‘technology agnostic’ approach, by installing the most energy efficient solutions.” He continues: “It’s also a chance for the government’s overdue review of electricity pricing – to make it fairer for households adopting low carbon electrical technology – to get back on track. Alongside this, the UK’s EV charging infrastructure must be significantly ramped up to satisfy customer demand and meet crucial safety standards”. Griff Thomas, from GTEC, believes that the ‘watered down’ plan is simply a bump in the road, stating: “Now the reality of the PM’s position has been communicated, it seems that his proposals are bumps in the road, which, if navigated properly, could still see Britain leading the way when it comes to combatting climate change. “Green policy gone wrong creates distrust and serves only to damage the reputation of renewables and other sustainability initiatives, feeding into the hands of climate change deniers. Poorly executed policy also leads to disengaged voters, which may be more of the inspiration behind the PM’s current management of expectations.” Right now, with so much uncertainty around many elements of our daily lives, it’s clear that government needs to adopt a pragmatic approach to Net Zero that is better able to support and encourage those that the targets affect, rather than abandoning the targets altogether. That approach might not help to win the next election, but it will put us on a far stronger path for the future. After all, is that not what all governments, regardless of the party running things, should be aiming to achieve? Have a good month and we’ll see some of you at ELEX Sandown Park.

New EWA routes approved for FESS industry The JIB has announced that two new routes to Electrotechnical Certification Scheme (ECS) gold cards for the Fire, Emergency and Security Systems (FESS) sector have been approved. The EAL Level 3 NVQ Diploma in Providing Electronic Fire and Security Systems, which is part of the FESS apprenticeship for Northern Ireland and Wales, is one route being used for experienced workers who have been in the industry for a number of years but do not have a completed apprenticeship of relevant qualiﬁcations. The other route now available is from BPEC, an awarding organisation with a history of operation across the building engineering services sector and an

end-point awarding organisation for the FESS apprenticeship in England. This route focuses on the principles of in-centre assessment to provide a route which maps the equivalent underpinning knowledge, vocational aspects and assessment of competence expected as if someone was completing an apprenticeship. Crucially, these experienced worker assessment routes are not training courses, but assessments for those already working in the industry, and therefore don’t require people to go back to college. They’re based on the principles of work-based assessment and provide a more cost and time eﬀective route to qualiﬁed status.

All Systems go with Aico training Aico’s free Expert Installer training scheme is FIA CPD accredited and designed to make sure installers have all the information they need to correctly install domestic home life safety systems. Once completed, Expert Installers are invited to join Aico’s Installer Community – an online, connected platform built to support Expert Installers. The online community allows individuals to connect with fellow professionals, share knowledge and best practice, and learn new skills. Members of the community are also eligible to participate in Aico’s free City & Guilds assured training on Domestic Fire and Carbon Monoxide Alarm Systems. New dates for City & Guilds training in 2024 will be released from within the Installer Community on a monthly basis, with members receiving a notification from the Installer Community when new dates become available. Attendees spend the day at Aico’s headquarters in Oswestry to participate in the City & Guilds training – Domestic Fire & CO Alarm Systems. The training is delivered by a member of Aico’s expert Technical Team with course materials that include a variety of theory-based and practical sessions, covering subjects that include Standards & Regulations and system design through to installation, integration and testing/maintenance.

Seaward tester plays the right notes for charity A charity that helps people who struggle with alcohol and drug addiction is using portable appliance testing to check the electrical safety of musical equipment used by the bands that play at its meetings. Roots Community, a not-for-profit organisation operating in Blackburn, has invested in a new Seaward PrimeTest 100 to test the safety of the electric guitars, amplifiers and microphones (among other items of electrical equipment) used by the local bands. The tester is also used by team leader Adam Taylor to check the in-service safety of a variety of electric kettles, cookers, dishwashers and microwaves available in

the kitchens of these venues, ensuring they’re safe to use by people attending events and comply with appropriate electrical safety regulations. The tester’s ease-of-use and portability is ideal for the charity’s requirements according to Adam, who volunteers to help out and travel from venue-to-venue to check that musical equipment is safe to use before every gig. He said: “I’d never used a PAT tester before, so the fact that the PT 100 is very simple and straightforward to operate is a great help. It’s easy for me to check every electrical appliance and item of equipment quickly and accurately.”

COVER STORY

THE RULES OF THERM How can the correct heating technology help thermal comfort? The experts at Rointe take a closer look. What are the key parameters for optimum thermal comfort? There are six principles of thermal comfort to deliberate when choosing or designing a heating system:

What does Rointe offer to help achieve maximum thermal comfort? Rointe radiators have been designed for comfort and efficiency, offering some of the following benefits:

l l l l l

hermal comfort is one of the keys to feeling comfortable in a home or room, and is a crucial aspect for improving day-to-day living. But do you really know how to achieve it? When designing a heating system, it is easy to forget to give thermal comfort the importance it deserves. There are, however, diﬀerent methods to measure the thermal comfort of a space.

What is thermal comfort? It’s a set of conditions which include air temperature, movement and humidity that all contribute towards a pleasant space. Its measurement is subjective as it depends on the subject’s feeling of thermal satisfaction. Depending on individual needs, you can reduce energy costs whilst maintaining the maximum level of thermal comfort. When designing a heating system, consider thermal comfort to achieve: l l l l

Reduction in heat loss Balanced energy consumption An increase in energy savings An increase in the well-being and health of the user.

The type of clothing worn by the user The temperature of the room Any physical activity the space is designed for The air speed within the room The rooms’ relative humidity The average radiant temperature of the room.

The Luesden and Freymark standard for comfortable warmth is 18-22ºC for normal, healthy adults who are appropriately dressed. For those with respiratory problems or allergies the WHO recommends no less than 16ºC, and for the sick, disabled, very old or very young, a minimum of 20ºC. With a temperature set to around 20ºC in winter individuals can maintain the optimum level of thermal comfort, without increasing energy expenditure. Did you know that decreasing the temperature by just 1ºC can reduce a heating bill by up to £85 per year? We also recommend keeping the airspeed of a heating system below 0.1 m/s and the relative humidity of the space between 40-70%. Falling outside of these parameters can have a negative impact on productivity and health, like sleep quality. Studies have shown that bedrooms with high temperatures lower the quality of sleep. Did you also realise that 90% of our time is spent indoors, with the majority in working environments and homes? So, maintaining an optimum standard of thermal comfort is important for everyone. High temperatures combined with high relative humidity serves to reduce thermal comfort and indoor air quality.

Best cost/conductivity material use: the aluminium of our radiators, together with their design, allows the steady increase of air temperature when circulating through the radiator internal fins. Thermal stability: the thermal fluid inside the radiator ensures that the temperature remains stable. Efficient and uniform heating: this is due to thermal resistance located at the bottom of the radiator. Natural humidity and temperature stability: the air rises gently in temperature as it passes through the radiator, creating a gentle natural convection cycle in your space.

All Rointe radiators and towel rails include patented energy-saving technologies, developed exclusively by our electric heating experts, to increase savings in the most eﬃcient way without reducing comfort. We call it ‘Fuzzy Logic Energy Control’ technology. This technology, together with Rointe’s energy-saving functions, achieves an equivalent consumption coeﬃcient of only 38% to maintain a stable temperature of 21ºC for 24 hours. A Rointe radiator will use, on average, only 38% of its nominal power once a steady working rate has been achieved. What is Fuzzy Logic Energy Control? Developed in-house by Rointe, Fuzzy Logic Energy Control is a specialised

The two main beneﬁts of the use of such technology are:

efficiency technology that improves the energy management required to maintain a stable temperature by accurately analysing thermal variations within ± 0.25ºC. Together with high purity aluminium and high heat transfer thermal fluid, our low consumption technology transfers heat to the atmosphere in the most efficient way for the user’s warmth and comfort. How does it work? By analysing temperature variations with an accuracy of ± 0.1ºC and sending readings every minute to the microprocessor, we ensure that the exact amount of energy is sent to the heating element at any given time. The heat generated is transferred to the thermal fluid and the aluminium that forms the radiator, so that it is dissipated in the most efficient way.

power of use) of our products based on their nominal power.

Energy optimisation: it predicts the amount of energy required at each moment until the set temperature is reached. This technology proportionally reduces the energy demand necessary to reach the desired temperature, smoothing the initial curve by damping the temperature peak.

Nominal Power X Equivalent Coeﬃcient Consumption Ratio = Eﬀective Power

Temperature stabilisation: once the room has reached the set temperature, the Fuzzy Logic Energy Control technology generates micro-cuts in the energy consumption of the heating element to maintain a stable temperature with a thermal variation of ± 0.1˚C.

Test results In an independent laboratory test carried out by BSRIA, a Rointe 1,430 W radiator with Optimizer Energy Plus technology was tested. This concluded that to maintain a room temperature of 21ºC with a variation of only ± 0.25ºC during a period of 24 hours, the radiator only needed an average of 572 W or 40% of its nominal power.

In addition, it allows you to achieve an equivalent coefficient of consumption of 38% of the nominal power of the product, which translates into energy savings during the operation of the radiator. Defined by Rointe, the equivalent coefficient consumption ratio is used to calculate the effective power (or average

So, for example, take one of our radiators with 990 watts then multiply by the equivalent coeﬃcient consumption at 38%. This gives an eﬀective power of 376 watts for the radiator, once the steady working rate has been achieved (normally after around 45 minutes of heating on full power).

Improving energy efficiency At Rointe, we wanted to develop a newer technology that would improve energy efficiency even further. Fuzzy Logic Energy Control improves the algorithm of our previous technology, Optimizer Energy Plus. In a comparative test, carried out in a fair climatic chamber, we tested the latest low consumption technology (Fuzzy Logic Energy Control) against the previous one. This concluded that Fuzzy Logic Energy Control was able to save a further 6% of energy and reduce the equivalent coefficient of consumption to 38% – our best ever results.

SPECIAL REPORT

LAYING THE FOUNDATIONS Andrew Eldred, ECA Director of Employment & Skills, explains why the updated Apprenticeship Standard in England includes green and digital skills to prepare for the UK’s Net Zero future. n May of this year, the Installation & Maintenance Electrician became one of six English apprenticeships recognised as a ‘gold standard’ for green skills. The award was part of the Coronation celebrations and reflects King Charles’ long-standing interest in sustainable technologies and renewable energy. It’s great to see our sector recognised for its essential role in helping the UK transition to a low-carbon future as we switch from fossil fuels to increasingly green electricity. And this has been one of the reasons behind upcoming revisions to the electrical apprenticeship standard.

Apprenticeship reflects low carbon technology As of September, the Installation & Maintenance Electrician apprenticeship in England has introduced several changes, some of which reflect the growing need for electricians who can help to achieve the country’s Net Zero Carbon goals (which have, albeit, been amended

recently). For example, it will include the foundation and cabling connection skills needed to install electric heat pumps. In addition, apprentices will learn to install EV charging points in most settings, such as large-scale residential, commercial and industrial areas. Completing apprentices will also receive an EV charging point qualification along with their ECS Gold Card. One of the most important points is that the apprenticeship will also provide a broader understanding of sustainable building solutions, so electricians can help their customers and clients choose products and installations for project requirements. In addition to sustainable skills, the updated apprenticeship recognises that the construction and built environment industries are adopting digital tools more widely. Apprentices will discover how to use these tools for business communication and collaboration and make the most of digital learning platforms.

The AM2S end point assessment will reflect the new content but. as always, the focus remains on providing the best possible learning process for apprentices and employers. The Institute for Apprenticeships and Technical Education estimates that the apprenticeship will take 48 months to complete, an increase of six months that reflects the additional content. Commercial and domestic skills Another significant change is that for the Installation and Maintenance apprenticeship, at least one of the on-site performance assessments for certain units must be in a commercial or industrial

setting. This reinforces the point that, for employers and learners in England working in a wholly domestic context, the alternative Domestic Electrician apprenticeship standard, launched in September 2022, is now the more appropriate training route. But new skills are not just for the new entrants to our industry. The Electrotechnical Experienced Worker Assessment (EWA) allows practitioners at a more advanced career stage, but without industry-recognised qualifications, to refresh their knowledge and skills and gain certification. Routes for experienced workers The EWA is for individuals who have worked in the industry for at least five years (not including training) but have not completed an apprenticeship or gained an equivalent Level 3 vocational qualification. The content of the EWA is the same as the Installation and

Maintenance apprenticeship, and the end point assessment is the AM2E, similar to the AM2S. An equivalent Domestic Electrician EWA, aligned to the domestic apprenticeship, was also launched this summer. Those who successfully complete the Domestic EWA (including the relevant AM2) will be entitled to apply for a ECS Domestic Electrician Gold Card. A key benefit of both the original and domestic EWAs is that existing skills, experience and qualifications can be taken into account, so only gaps have to be filled with further training. They will become an excellent way to learn new low carbon and digital skills while topping up other areas – and gaining an ECS Gold card. As infrastructure, homes and commercial properties decarbonise and ‘go electric’ with EV charging, heating and on-site energy generation, there has never been more demand for fully qualified and competent electricians.

Our industry is seeing growing interest from experienced individuals who want to gain a recognised qualification. This has been partly driven by changes in the requirements for Qualified Supervisors under the Electrotechnical Assessment Specification (EAS). The need to appoint a suitably qualified person within an enterprise has given an impetus to those who want to take the next step up the ladder or for sole traders who must take on that role themselves. ECA aims to open a pathway for an individual to become an “Electrician Plus”, building on the core trade competence achieved from the apprenticeship or EWA and growing their qualifications, knowledge, skills and experience over their entire career.

SPECIAL REPORT

As the tool theft pandemic shows little sign of slowing down, we learn more about two professionals from alternative trades who have decided to fight back with the help of a new protection service.

ARMD POLICING

Heating engineer is hot on the case Founded and led by Matt Green, Reheat has established itself as a trusted local business in Richmond-upon-Thames and the surrounding area. However, the heart of Reheat's success lies in the tools used by its engineers, which like most tradespeople, makes them a prime target for thieves. The unfortunate reality is that van and tool theft has become an increasingly prevalent concern for tradespeople in recent years, with a staggering 150% increase in van break-ins within the UK over the past two years alone, averaging one every 19 minutes. Shockingly, 86% of the culprits go unpunished. The impact of tool theft extends beyond the financial aspect. Insurance settlements often take weeks or months to process, and without their tools, tradespeople are unable to work, leading to an average daily income loss of £350. Some installers have even been unable to file claims due to not meeting specific policy requirements. Despite Matt's awareness of the risk of tool theft and his efforts to secure his vans, his company fell victim to theft when one of his engineers parked his van in a supermarket car park during the early evening, only to return and discover it had been broken into. The thieves made off with expensive and vital tools, resulting in a significant financial loss and operational disruption for Reheat. Facing these challenges, he turned to ARMD, a service tailored for tradespeople. ARMD's user-friendly App, smart van alarm and tracker, in combination with innovative insurance, offer comprehensive protection in four key ways: recording, protecting,

insuring and replacing. ARMD's tool insurance is speciﬁcally designed to assist tradespeople in swiftly recovering from theft incidents, providing comprehensive coverage 24/7, so eliminating the need to remove tools from vans at night. In the event of a claim, tradespeople can automatically submit a Claim Report directly from the App, streamlining the process and minimising business disruptions. The ARMD GUARD Smart Van Alarm and tracker oﬀer an added layer of protection, notifying users of break-ins via a phone call and enabling immediate action. GPS tracking aids in the location and recovery of stolen vans, giving peace of mind to business owners like Matt.

Auto business recovers from shocking raid James Flamson is a skilled, self-employed auto-technician with extensive experience who, over the years, has worked with renowned automotive companies like Renault. Over time, his business has

transitioned from servicing customer vehicles to installing camera and safety systems on trucks through to camper van conversions. Nowadays, James ﬁnds himself spending more time on the road than in the workshop, making his van – and the tools within it – vital to his business operations. When it comes to building camper van conversions, James relies on a wide range of tools: sanders, drills, angle grinders, nail guns, ratchets, impact drivers… the list is endless. Having accumulated this inventory over the years, he remembers the challenges he faced at the beginning and understands how devastating it would have been to lose his tools. During the early stages of ARMD's development, James came across an advertisement for the App. Little did he know that it would prove invaluable when the unthinkable happened last October — the unit where his camper van business is based was broken into and his tools were stolen. However, thanks to ARMD, the claims process was incredibly straightforward.

“I wasn’t using the App at the time, but I used all my email receipts for tools, worked out what was gone, added it all onto the App and submitted my claim,” James explains. “It was easy to make a claim via the App and I simply listed all the tools from my inventory that were missing, went on holiday and then the money came into my account. I could then order all my tools before I even got home! It was a really smooth process – from submitting the claim to getting the money, it took less than a week.” James has since listed all his tools on the ARMD App, which not only proves useful for potential future claims but also provides him with a comprehensive overview of his inventory, including the age of each tool. This feature allows him to maintain an up-to-date record of his tools. “The App is easy to use. If you have receipts, get them all added in. But if you want to, you can photograph your tools and use that as well to help with proving purchase. You can add photos just as easily as any other information,” James adds.

SPECIAL REPORT

Richard Fogelman, Chief Executive of the National Security Inspectorate (NSI), sheds light on the dynamic landscape of fire safety requirements that impacts individuals and presents opportunities for electricians to provide third party approved services.

JOIN THE (THIRD) PARTY ince the tragic Grenfell Tower incident in June 2017, fire safety has rightfully taken centre stage. Subsequent official enquiries into the disaster have led to legislative changes and stricter building regulations. Those living in flats and working in offices, shops and a range of other buildings are being increasingly protected by requirements including mandatory fire risk assessments. Those designated as responsible at each location must ensure the thorough execution of these assessments and the implementation of recommended physical and electronic (passive and active) fire safety measures and procedures. These include the fitting and periodic maintenance-related inspection of appropriately rated fire-resistant doors, fire detection, extinguishing, alarm systems, and emergency evacuation procedures – contingent upon the type of building involved.

Opportunities for electricians Amid this changing landscape, electricians and installers play a pivotal role in ensuring the fire safety of buildings. Building owners, managers and company directors – while legally responsible for these measures – aren’t usually suitably qualified in this specialist area.

This is where third party approved services can play an important role, providing independent verification that all necessary site-specific procedures and measures align with fire safety standards and regulations. Certified service providers, such as those approved by NSI, have visibly demonstrated compliance with legal fire safety criteria and can ensure relevant insurance requirements are met. Duty Holders/Responsible Persons Multi-occupancy residential buildings in England (i.e. containing two or more flats), as well as commercial premises throughout the UK, must comply with increasingly stringent fire safety measures. The ‘Life safety fire risk assessment’ (LSFRA) is legislatively required for almost all these premises and underpins fire safety arrangements. Fire risk assessments help identify potential fire hazards, assess the level of risk and implement appropriate fire safety measures. The regulatory framework identifies ‘Duty Holders’ who bear the legal responsibility for fire safety (referred to as the ‘Responsible Person’ in the Regulatory Reform (Fire Safety) Order 2005, introduced in England and Wales in October 2006 – other similar legislation covers Scotland and Northern Ireland). These individuals are often employers, owners or managers of premises.

32 November 2023 PROFESSIONAL ELECTRICIAN

While fire safety legislation doesn’t explicitly define the competence of fire risk assessors, government guidance states that where identified Duty Holders are unwilling or unable to complete an LSFRA, advice should be sought from a demonstrably competent person. The guidance recommends that assessments be conducted by individuals with comprehensive training and experience in the specific type of fire risk assessment required. Role of third party certification Third party certification bodies like NSI inspect organisations against the BAFE Life Safety Fire Risk Assessment Scheme SP205, which exists to ‘deliver quality, independent evidence that providers are competent to deliver quality fire risk assessment services’. Such certifications provide Duty Holders with reassurance and an objective assessment of capabilities and adherence to established standards. As the independent registration body for third party certificated fire safety organisations across the UK, BAFE develops specialist schemes for the fire sector in conjunction with stakeholders including NSI, the National Fire Chiefs' Council (NFCC), insurance companies and the fire safety industry, in the public interest.

Latest regulatory requirements Recent amendments to the Regulatory Reform (Fire Safety) Order 2005 introduced through the Building Safety Act 2022, require Responsible Persons to record their fire risk assessment in full, not just the significant findings. These changes, effective in England from 1st October, are part of a broader set of stringent regulatory requirements enforced by local Fire & Rescue Authorities, with penalties for non-compliance including fines or even imprisonment. Those responsible for the fire safety of approximately 12,500 high-rise residential buildings in England are now subject to

fresh legal requirements under the Building Safety Act 2022. The Building Safety Act defines "higher-risk" buildings as those 18 metres tall or higher, or at least seven storeys with two or more residential units. Building owners, freeholders or management company directors referred to as “Accountable Persons” must comply with the Act from October or face investigation and potential prosecution. While these requirements apply in England, separate amendments to the Building Regulations (Approved Document B) came into effect on 1st December 2022. These amendments require the installation of evacuation alert systems in all new high-rise residential buildings. The installation of evacuation alert systems in new residential buildings of 18 metres and above required the introduction of standard BS 8629: 2019 to ensure the effectiveness of these systems when

installed. Amendments to this standard were considered just two years later and introduced in March, reflecting the evolving nature of this fire safety measure. Existing buildings of this height that undergo substantial alterations in the future also fall under these requirements. However, similar mandates don’t currently cover Wales or Northern Ireland. Conclusion With fire safety-related changes evolving and affecting those responsible for safeguarding their premises, customers and building visitors, professional electricians and installers have a crucial role to play. Through third party approved services, they can assist in the implementation of measures that mitigate the consequences of fire and safeguard lives, property and business reputations.

ASK OVIA

The column where you get to put your lighting questions to the head of the Ovia lighting business, Mike Collins, and his team of technical experts.

WHICH LIGHTING PRODUCTS WOULD YOU RECOMMEND FOR A WAREHOUSE AND WHY?

We’ve recently reviewed and upgraded the warehouse lighting at another of the Scolmore Group companies, ESP, to replace old incandescent light fittings with much more energy efficient LED alternatives. In general, we would recommend the Ovia Inceptor Hi-Lite LED dimmable Highbay luminaire with microwave sensor. There are various considerations to take into account when selecting a microwave sensor, such as the size of the space, and potential triggers such as ventilation fans, vibrations and water pipes. The parameters of the sensor can be changed to accommodate different applications and to eliminate any false triggering. The Hi-Lite highbays are CCT switchable in 4000K, 5000K and 6500K, and come in black as standard and in a choice of wattages – 100, 150 or 200 W. They can be wall mounted or suspended which makes them very versatile. The luminaire can be mounted up to 12 m in height with a detection range of up to 15 m, while a chain mounted hook is supplied as standard. The Hi-Lites can also be set to turn off immediately after an area is vacated or set to a secondary level for security purposes for a set time. Whether you’re starting from scratch with a new build or you’re retrofitting an existing warehouse and lighting system, Ovia offers a free design service with a team of lighting experts on hand. They provide expertise in selecting the right products and solutions to create a scheme that meets all requirements and objectives of the project and is compliant with all the relevant regulations and standards.

You ask: I OFTEN WASTE A LOT OF TIME WHEN I’M WORKING ON LIGHTING CIRCUITS BECAUSE I NEED TO TAKE THE FITTINGS OR LAMP HOLDERS APART TO GET AT THE CONNECTIONS TO CARRY OUT TESTS. SURELY THERE MUST BE AN EASIER WAY! DO YOU HAVE ANY IDEAS?

Megger says: There is indeed an easier way. We suggest that you get hold of one of the new Megger LA-KIT lamp adaptor kits, which have been developed to solve exactly the problem you describe. The kit comes in a handy zipped carrying case and includes five adaptors to match all of the most commonly used types of lamp holders. These are B22 and B14 bayonet fittings, E27 and E14 screw fittings and GU10. The adaptors are really easy to use – you simply plug them in instead of the bulb. They have two standard 4 mm sockets for the test leads, and the LA-KIT even includes a two-wire 4 mm to 4 mm lead set. The E27 and E14 adaptors are colour-coded to show polarity, but because they can be plugged in either way round, colour-coding isn’t possible for the other adaptors. The lamp adaptor kit is inexpensive, and it will save you a lot of time and trouble. You’ll be especially glad to have it when you’re working at height, where plugging in an adaptor is a lot simpler and safer than trying to dismantle a lamp holder or fitting!

THE

CODEBREAKERS CHARLOTTE ROBINSON: THIS WAS THE GLAND FOR THE PV SUPPLY IN AN INDUSTRIAL UNIT. NOT ONLY DOES IT LOOK LIKE THE GLAND WAS MADE OFF WITH THE INSTALLER’S TEETH, BUT THE BEDDING DOESN’T EVEN MAKE IT TO THE GLAND. AND WHAT’S GOING ON WITH THE LOCK NUT? With the advent of high fossil fuel prices and the demand for zero-emission electric vehicles, solar PV in conjunction with battery storage will most likely start to grow exponentially. The problem with that, as with EV and any other installation, is that it has to be done properly to be safe. As we can’t see what else is going on here, I’ll just confine the coding to the SWA gland. First oﬀ, the armouring isn’t anchored adequately by the gland nut, some of the strands are actually inside, contacting the single insulated conductors, and some are on the outside. It’s likely that the armour isn’t adequately held and lacks mechanical strength. I can’t confirm if the armour is connected to the cpc, at the other end, by a banjo hidden from view or by contact with the metal enclosure, so I won’t comment on it and assume it’s taken care of. What we can assume, though, is that there is an issue with the mechanical strength of the joint – the joint in this case being the SWA strands, meeting the SWA gland. Single insulation must be taken inside an adequate enclosure; the surrounding armour strands are not considered to be an adequate enclosure. Cutting the filler, or bedding material, too short shows a lack of experience or poor skills, which has now led to a potentially dangerous install. C Although an excessive amount of the black PVC casing is stripped back, I’d hardly see that as a big problem.

As for the lock nut, without seeing the install first hand, I’m confident the wrong size hole saw, or knock out, has been used, and the gland didn’t sit properly. It’s likely the lock nut is being used to bridge the gap made by the oversized hole saw. It’s not ideal, but I think it would be unfair to code it unless there were signs it compromised the installation safety in some way.

PROTECTIVE EQUIPOTENTIAL BONDING This article from the experts at NICEIC discusses the purpose of carrying out protective equipotential bonding in commercial and/or industrial type properties, and how to verify the electrical continuity of protective bonding conductors in such a location. Introduction The majority of electrical installations typically use Automatic Disconnection of Supply (ADS) as the protective measure for protection against electric shock. In this article, the requirements of BS 7671 for protective equipotential bonding where ADS is used are considered. ADS is a protective measure in which: l

basic protection is provided by basic insulation of live parts or by barriers or enclosures, in accordance with Section 416; and fault protection is provided by protective earthing, protective equipotential bonding and ADS in the event of a fault, in accordance with regulation Groups 411.3 to 411.6 (411.1 refers).

Where it is not feasible for an overcurrent protective device (OCPD) to provide the necessary disconnection time in accordance

with regulation 411.3.2, or the use of an RCD for such purpose is not appropriate, reference should be made to Section 419 (411.3.2.5). Purpose of main protective bonding In the event of an earth fault (a fault between a line conductor and an exposed-conductive-part or a protective conductor), a dangerous voltage – or more correctly, potential diﬀerence – can occur between simultaneously accessible exposed-conductive-parts and extraneous-conductive-parts in the installation, as shown in Fig 1. The primary purpose of main protective bonding is to limit the magnitude of any potentially hazardous touch voltages that may appear on exposed and/or extraneous-conductive metalwork within an equipotential zone with exposed-conductive-parts. Requirements for protective bonding In each consumer’s installation within a

building, main protective bonding conductors complying with Chapter 54 of BS 7671 are required to connect any extraneous-conductive-parts, which are liable to introduce a dangerous potential diﬀerence, to the MET in accordance with regulation 411.3.1.2. Extraneous-conductive-parts may be considered as conductive parts which do not form part of the electrical installation but may inherently introduce a potential, generally Earth potential. Regulation 411.3.1.2 lists examples of items that can be extraneous-conductive-parts. The note to 411.3.1.2 states that where non-metallic services, such as polyethylene gas or water pipes, enter a building and are then connected to metallic pipes within the building, as they are unlikely to be extraneous-conductiveparts there is no requirement to provide protective equipotential bonding. Regulation 411.3.1.2 also requires that the connection of a lightning protection

system to the main bonding shall be in accordance with BS EN 62305 – Protection against lightning. The regulation further states that main bonding conductors shall be connected to the metallic sheath of any communications cable at the premises, provided that the consent of the owner or operator of the cable has been obtained. Where consent is not granted, such details should be recorded on the appropriate electrical certiﬁcation. Commercial or industrial installations As mentioned previously, it is a requirement for all extraneous-conductive-parts such as exposed structural steelwork, to be connected to the MET. However, what designers and installers may not appreciate is that, in many cases, the structural steelwork can be utilised as a protective bonding conductor, as shown in Fig 2 (543.2.1 (vii)). Where the steel structural framework of a building is to be used as a protective conductor, regulation 543.2.6 requires the following conditions to be met: (i) its electrical continuity can be assured for the life of the installation; (ii) the cross-sectional area (csa) of the steelwork is not less than the minimum csa given by the application of regulation 543.1.1 whether: l l

calculated in accordance with regulation 543.1.3; or selected in accordance with regulation 543.1.4;

(iii) unless compensatory measures are

provided, precautions shall be taken against its removal; and (iv) it has been considered for such a use and, if necessary, suitably adapted. Using the steelwork as a protective bonding conductor provides many benefits, not least that less cable is needed, particularly in larger installations, and that the steelwork provides a more convenient and efficient method of maintaining continuity as the steelwork is unlikely be removed. The connection from the accessory to the steelwork must be electrically and mechanically secure for the duration of the installation (526.1). Where a bonding connection is to be made, it is necessary to obtain prior permission before drilling holes arbitrarily. An alternative method is to have a connection plate (as shown in Fig 3) welded to the structure. Other methods of making a secure connection are not precluded. Verification of electrical continuity As with all protective bonding conductors, unless it is clearly visible throughout its full length and it can be assured the connections are electrically and mechanically secure, it will be necessary to perform continuity testing (643.2.1(i)). Such testing ensures that all protective bonding conductors, where fitted, are not only continuous but provide a sufficiently low ohmic value. Any extraneous-conductive-part without an effective connection to Earth will not provide an equipotential zone with any simultaneously accessible exposed-conductive-parts, which may lead to a risk of electric shock in the

event of an earth fault. The test method typically used is the long lead (wandering lead) method, as shown in Fig 4. Before using a long lead, it should be remembered to null the test leads or make a note of their resistance before carrying out the test. Having temporarily disconnected the main protective bonding conductor from the MET, the leads of the instrument should be attached, as shown in Fig 4. Note that where structural steelwork is used, it will be difficult to isolate any potential parallel paths. Where significant differences are observed in the resistance readings between simultaneously accessible extraneous-conductive-parts and exposed-conductive-parts, it may be necessary to install supplementary bonding – for example, as shown previously in Fig 1, between the metal cased motor starter and the structural steelwork. Note: It should be remembered to reconnect the main protective bonding conductor to the MET after completing the test. Summary The primary purpose of main protective bonding is to minimise the magnitude of any touch voltages. Where the building structure consists of substantial steelwork, regulation 543.2.1 (vii) permits its use as a protective bonding conductor. As part of the verification process for ensuring continuity of any protective bonding conductor, there is no difference in the testing procedure where the structural steelwork has been used in preference to the use of individual copper cables.

A GUIDE TO FIRE RATED DOWNLIGHTS This article, based on a seminar by ROBUS, looks at how fire rated downlights work and explains more about the legislation governing their use. lso known as can lighting or recessed lighting, you’ve most likely received requests for downlights for a range of commercial and residential spaces due to their versatile, sleek design. But if you need to install downlights in a ceiling, what are you going to have to do ﬁrst? The answer is, you’ll have to create an opening in that ceiling! This is why ﬁre rated downlights were invented.

Why do you need fire rated downlights? Imagine a plasterboard ceiling; perhaps there is one above your head right now. This ceiling helps slow the spread of fires because it works as a barrier. In multi-storey buildings, where people reside on different levels, the ceiling below them must be fire protective in accordance with fire safety building regulations. Once an opening is made in the ceiling, this barrier is compromised – think of water running down your bathtub’s drain, but the water is actually fire! Fire rated downlights are

designed to combat this issue with an intumescent seal. The lifesaving intumescent seal Intumescent material does not burn immediately on exposure to heat but usually expands in volume while decreasing in density. Effectively, it fills the opening in the ceiling, restoring its fire resistance. Intumescent seals can be made from a range of synthetic polymers and resin binders, such as silicone or epoxy. Visually, there are only slight differences between these downlights; but these differences are crucial. Once swollen, the intumescent seal blocks the spread of fire for a pre-determined period of time. This delay gives the building users time to escape to safety while also protecting the property. Different ceilings have different levels of fire protection Fire rated downlights are not a one-size-fits-all solution. They receive ratings based on two factors: a) how long

48 November 2023 PROFESSIONAL ELECTRICIAN

they can resist fires, and b) the specific type of ceiling they can be placed in. To restore the integrity of the punctured ceiling, you must install a fire rated downlight that meets the fire protection requirements of that ceiling. Fire resistance is determined by the size of the dwelling Downlights being installed on the top floor of a dwelling with no living space above technically do not require a fire rating. However, to stop the spread of fire through the attic space from one property to another, it is recommended that a fire rated product be installed. I-Joist rated downlights The I-Joist offers an advanced structural alternative to the traditional solid timber approach; however,

048_PE_NOV23_Layout 1 05/10/2023 15:31 Page 49

will meet the specific specifications you need. While a supplier might offer a test report to confirm the product's fire rating, it could be rated for only 30 minutes, for example.

greater fire safety precautions are required compared to those for solid timber. Even if a downlight conforms to the original fire endurance standards, this doesn't necessarily imply its adherence to I-Joist compatibility for your specific project. Choosing your fire rated downlight

How do downlights earn their fire-rating? Trial by fire is the answer! The process involves a ceiling subjected to fire that exceeds 600˚C (you may recall the TV show Brainiac: Science Abuse at this point). This test fails if the roof caves before the time period expected. If, during a 30-minute test, the ceiling collapses in 40 minutes, the fixture will pass the test. If it crumbles in 20 minutes, it’s a failure. Always check the technical specifications to ensure it is designed to meet the fire protection required. At ROBUS we describe a fire rated downlight as being “Designed and tested to retain the integrity of 30, 60 and 90-minute fire rated ceilings – compliant with Building Regulations Parts B, C and E” and that it is “Tested for use with I-Joists & Metal Web Joists”. Warning: never assume that a product labelled as 'fire rated'

What are the building regulations for downlights? When it comes to fire safety in buildings, Part B of the Building Regulations is the go-to. This covers a variety of topics such as installation rules, building code compliance, and regular inspection and care. It is important to have qualified professionals (that’s you) install fire rated downlights in accordance with manufacturer guidelines and fire safety regulations. These regulations require specific flame-retardant standards, ranging from 30 to 120 minutes. Always use approved models for your specific location. Regular checks and upkeep are necessary to maintain fire safety. However, it’s worth noting that changing lamps can be done as a DIY project, and surface-mounted downlights do not require a fire rating as they do not form part of the ceiling structure. Summary Fire rated downlights gracefully bridge the gap between aesthetics and safety, catering to various ceiling types and fire resistance needs. While adhering to regulations is essential, they're more than just regulatory compliance; they're a testament to smart design meeting life-saving functionality.

Frank Bertie, Chief Technical Oﬃcer at NAPIT, explains when to use an intended departure.

BREAKING THE RULES hen we look at a completed electrical installation or minor works electrical installation certiﬁcate, there are several areas where the information may be incorrectly recorded. One of the most common errors is where the ‘departure’ ﬁelds have been completed and have details recorded. Even though the information regarding departures was updated with the introduction of BS 7671:2018 edition, and a minor change under Amendment 2, there still seems to be confusion as to what a departure from the requirements of BS 7671 is. For some reason, the term ‘departure’ is often regarded as either a ‘defect’, ‘omission’ or a ‘non-compliance’. Therefore, a ‘departure’ appears to have

READERLINK 025

different meanings to those completing electrical documentation. Previously, the lack of a definition in Part 2 of BS 7671 created a great deal of confusion as the term ‘departure’ is mentioned a number of times in BS 7671. Although departure is now included, as is non-compliance, ‘defect’ and ‘omission’ still remain undefined. The difficulty regarding departures is further compounded by the lack of published guidance. So, what is a ‘departure’? The term, ‘departure’ is used within BS 7671 in Chapter 12 Regulation 120.3 where it is called an ‘intended departure’ and refers to ‘these parts’. Any ‘intended departure’ is the consideration of not following any of the technical requirements related to Chapter 13 Fundamental Principles and Parts 3-8, so it has to be a conscious decision taken after full and in-depth consideration. An intended departure from BS 7671 is where the designer of the electrical installation, after due care and attention, decides to use a method of installation which is not recognised in BS 7671. The best example of this is where there is a new material or a new invention planning to be utilised as part of the electrical installation, ‘where the use of a new material or invention leads to departures from the Regulations’. Therefore, it is the designer’s responsibility to confirm that the

‘intended departure’ results in the degree of safety of the installation which shall not be less than that obtained by compliance with the Regulations and shall be noted on the electrical installation certification specified in Part 6. What is the definition of a ‘departure’? This definition was introduced in Part 2 of BS 7671:2018, where the wording states: ‘Deliberate decision not to comply fully with the requirements of BS 7671, for which the designer must declare that the resultant degree of safety is not less than that achievable by full compliance’. By clearly laying out the expectations of the departure, the designer should not be taking this lightly. To meet the full compliance of BS 7671, considerable details would need to be provided, so that those installing, inspecting and testing the electrical installation are also aware of the implications of such a decision. Additionally, the client would have to be informed of such an undertaking prior to including it as a departure as they would be within their rights to reject such a process unless it can be confirmed that electrical safety is not less than fully compliant. Incorrect recording of departures Even though the definition provides a clear description of what this is, there’s still instances in which the items on electrical certification are incorrectly recorded.

These have been included when an addition or alteration has been carried out, and items that have been recorded under ‘Comments on existing installation’ in Electrical Installation Certificates (EIC) or Minor Electrical Installation Work Certificates (MEIWC) are sometimes recorded as ‘departures’ when they are not actually departures. Even when periodic inspection and testing is carried out, items are sometimes referred to as ‘departures’ when they are ‘observations’, which need to be noted in Section K, Observations of the Electrical Installation Condition Report (EICR) and given a Classification Code – C1, C2, FI or C3. The following are some examples of items incorrectly listed as departures where: l l l l

Switch lines have not been identiﬁed as line conductors at the terminations Wiring colours have two versions of BS 7671 BS 3871 circuit-breakers are installed Voltage operated ELCBs are in use within TT systems, which have been proven to operate correctly BS 3036 rewireable fuses are in use.

Discussions on the appropriate code to assign to some of these observations on an EICR can be had, but we have to agree that none of them is an ‘intended departure’ as referred to in Regulation 120.3. Departures that may give rise to danger It is possible that a designer, who has included a departure from BS 7671 into their design, may have incorrectly assumed that it is no less safe than would be achieved by compliance with BS 7671; it may even give rise to danger. As per the changes under BS 7671:2018, previous Regulation 621.2 (iv) listed departures that may give rise to danger was part of the reason for the changes and deﬁnitions for ‘departure’. Regulation 621.2 was replaced with Regulation 651.2, and bullet (vi) now refers to non-compliances which give rise to danger. The term ‘non-compliance’ was also reintroduced into the deﬁnitions to

Fig 1: Electrical Installation Certificate (EIC) highlighted sections for recording intended departures

clarify the misunderstanding regarding departures. Under installations designed by others, the installers have a duty to highlight to the designer any aspects of the design which they consider conflicting with BS 7671 and which they believe to be unsafe. There is no legal defence against creating an unsafe installation based on poor and non-compliant instructions. When carrying out inspection and testing on an existing installation and recording the information on an EICR, there is no provision for recording ‘intended departures’. If any such departures have been recorded on the original EIC or MEIWC, the inspector should have this information to enable them to determine if these would be classed as a non-compliance which could give rise to danger, or be recorded for information in either Section K, Observations, or on a separate sheet appended to the EICR, or both. ‘Intended departures’ must be recorded In accordance with Regulations 120.3, 133.1.3 and Regulation 133.5, details of any intended departures are required to be recorded on the Electrical Installation Certificate (EIC) (see Fig 1), or Minor Electrical Installation Works Certificate (MEIWC), as an example of where to list the intended departures. In each of its three signature sections for design, construction and inspecting and testing, the EIC makes provision for recording departures for Regulations 120.3 and 133.5, with the designer solely responsible for specifying new materials

52 November 2023 PROFESSIONAL ELECTRICIAN

under Regulation 133.1.3. In larger installations, there may be mutual responsibility for the design. In domestic and similar installations, where an electrician often takes on all three responsibilities and a single signature EIC may be used, the electrician effectively becomes a designer. In the case of most installations where there are no departures, the word ‘None or N/A’ should be inserted, rather than leaving the spaces blank. In the certification model forms prescribed by BS 7671, there is little room for including details of departures; therefore, it is usually necessary for departures from BS 7671 to be declared in other documents, such as specifications and/or operating manuals. Such documents normally include a description of how the system is to operate and provide sufficient information to enable it to be used safely. Consequently, it would be appropriate to include reference to these intended departures in handover documentation. Conclusion A departure is not a ‘defect’, an ‘omission’, an ‘observation’ or a ‘non-compliance’. It is, however, an intended design decision taken after special consideration by the designer of the installation. Hopefully this has clarified some of the confusion over what a departure is and what it is not.

STRIPPING BACK CABLE ENERGY WASTAGE Jake Hardcastle, Electrical Design Engineer at Thornley & Lumb Partnership, identifies some of the real hidden costs of inefficient cable calculations. esigning an energy-efficient electrical installation involves thoughtful consideration of various factors in order to minimise energy consumption and maximise sustainability. When designing electrical installations, designers should not only design a system that meets the clients’ needs, is cost-effective and is compliant with BS 7671, but also one that is energy efficient. This will commonly be considered through selected luminaires, lighting control, selection of energy efficient appliances etc. However, one often overlooked source of energy wastage is inefficient cable sizing, and in a bid to reduce energy costs as much as practically possible, it is crucial to consider this. While the idea of sizing a cable to reduce energy loss is nothing new, the continuous search for cost reductions, competitive tendering and the rising price of copper mean selecting a larger conductor size doesn’t seem economically attractive and many will often fail to notice the benefits.

Reconsidering cable size In this article I want to delve into the impact of cable sizing on energy consumption and highlight the advantages gained from selecting a larger conductor size than what is strictly necessary – something that is often not given any consideration. By intentionally selecting a larger conductor size, we can effectively reduce wasted energy. We will examine the potential savings and long-term benefits of using a larger cable size. Section 17.4 (Design Considerations) within Appendix 17 of BS 7671 states that: “consideration should be given to limiting the voltage drop within an installation to a level below of that required”. These values can be found in section 6.4 of Appendix 4. By reducing the voltage drop further than what is required, we can reduce the power wasted in the form of heat through a conductor. Selecting a cable size larger than what is the minimum required in order to satisfy BS 7671 can minimize energy wastage, providing a more energy efficient installation, and furthermore, can reduce

the client’s electricity costs. Increasing the cross-sectional area will reduce energy wastage but will increase initial installation costs. The designer should determine whether the savings over a certain time period outweigh the initial higher cost. There are, of course, practical restrictions to this such as the size of terminations and the ability to be able to actually terminate the conductor within accessories. Additional recommendations on the energy eﬃciency of electrical installation design can be found in Appendix 17 of BS 7671:2018, Amendment 2:2022. Calculating energy wastage To calculate the energy wastage in a cable, two things need to be known: a) the current in the cable, b) the resistance of that cable. The resistance values of cables can be found in the IET On-site Guide (Appendix I) and IET Guidance Note 3: Inspection and Testing.

Using an example of a 32 A EV charging point, supplied from a consumer unit 10m away, we can look at three diﬀerent cable sizes and the comparisons on energy wastage. In order to calculate this, two of the basic principles of electrical engineering are to be used. We can use the two following formulas to calculate the power wasted within a cable: V=IR (Ohm’s Law) and P=IV (Power Formula). As resistance is directly proportional to voltage, i.e., if resistance is increased, voltage will increase and therefore the higher the resistance of the cable, the greater the voltage drop will be. As voltage and power are also directly proportional, the greater the voltage drop in the cable, the greater the power wasted will be. As voltage drop increases, the voltage available for the connected appliance decreases, resulting in reduced eﬃciency and wasted energy. Therefore, the voltage drop should be aimed to be as low as practically possible while striking a balance between energy savings and economic considerations. As the current of the circuit and resistance of the cable will be known, but not the voltage drop within the cable, we can substitute V in the formula P=IV for IxR in the Ohm’s law formula. This leaves us with P=I2R. This will give the power wasted within the conductor. The spreadsheet (pictured above) shows an example of three cable sizes used in this scenario. Assuming the minimum conductor size permitted is 4mm2, in this example we can look at two additional larger conductors to be considered in this design. Looking at the spreadsheet it can be seen that 4mm2, 6mm2 and 10mm2 are

the three cable sizes considered. Using a Steel Wire Armoured cable in this example and therefore the Circuit Protective Conductors being the same size as the Live conductors, the resistance values (mΩ/m) can then be selected from the On-Site Guide or GN3, as seen in column 2. Total cable resistance In order to calculate the total cable resistance, this value must be multiplied by the length of the circuit and divided by 1,000 to convert from mΩ’s to Ohms. Using the formula I2R, the current demand and resistance can be inputted to give the power wasted in the cable. This figure can be divided by 1,000 and multiplied by the hours used per year to give Kwh per year. This example is based on the usage of an EV charging point for 4.5 hours per day, five days per week over 50 weeks of the year. This figure can then be multiplied by the Kwh per unit charge which will vary depending on the energy provider and the time of day. In this example a figure of 35p per Kwh is used. It can be seen from the table that using a 6mm2 cable opposed to a 4mm2 cable would give an annual saving of £12.34. Using pricing found at the time of writing this article, 3 core 4mm2 Steel Wire Armoured Cable can be purchased for £2.93 a meter and 6mm2 for £4.08, meaning 10m would cost £29.30 and £40.80 respectively. This means the payback period for using 6mm2 compared to 4mm2 would be a little under one year and you would see a saving in subsequent years. Using 10mm2 cable gives a further saving of £10.08 compared to 6mm2 cable and a total saving per year of £22.42 compared with 4mm2 cable. The cost of

56 November 2023 PROFESSIONAL ELECTRICIAN

10mm2 3 core Steel Wire Armoured is £6.52 per meter, totaling £66.20 for 10m, £25.40 more than 6mm2 or £36.90 more than 4mm2. The payback period for the 10mm2 cable compared to using 4mm2 cable would be approximately 1.64 years: Payback Period = Initial Cost / Annual Savings = £36.90 / £22.42 = 1.64 years It can be concluded that the payback period, even for the 10mm2 option, is relatively short considering how long something such as an EV charger will be in service for. If the client was to have ownership of this installation for a long period of time it would be worth paying the additional installation costs for the savings that will follow each year, as well as the reduced power wasted and subsequent energy-efficient installation. Never underestimate cable sizing By selecting a larger cable with a lower resistance, energy efficiency can be significantly improved. As well as increasing cost-effectiveness and reducing electricity bills, this contributes to a greener, more sustainable planet. In pursuit of the most energy-efficient electrical design, the importance of cable sizing should not be underestimated. This example shows the impact of cable selection on energy consumption and while this shows the potential savings of only one circuit, consider very large homes with a hot tub, sauna, multiple EV chargers etc. – the savings could be significant. If we then translate that to an industrial environment, the benefits could be even greater.

There can be many reasons for problems like these, but one that’s surprisingly common (yet often overlooked) is inrush currents. When we think about loads – motors, lights, IT equipment etc. – connected to an electrical installation, our primary concern is often with the current that the load draws from the installation: “that motor will draw about 30 A”, or “those lights will take about 2 A”, and so on. But these are steady-state currents and, important as they are, they don’t tell the whole story. That’s because many types of load don’t draw their steady-state current from the moment they’re switched on. Before they settle into the steady-state condition, they draw a much larger current for a relatively short period of time. This is the inrush current.

An example When a motor is energised using an ordinary electromagnetic starter, it can draw an inrush current that’s up to ten times its normal running current. And, particularly if the motor is heavily loaded, it can take several seconds for the current to settle back to the steady-state value. Transformers draw even higher inrush currents at switch on – up to 25 times their normal rated current. Even switch-mode power supplies, which these days are used in everything from computers to LED lighting systems, often draw surprisingly large inrush currents. In

other words, loads that draw inrush currents are everywhere! Why does this matter? Problems resulting from inrush currents can be divided into two categories. The ﬁrst involves circuit protection equipment, such as circuit breakers and fuses. The purpose of these is to trip (or blow) if they’re subjected to a higher than normal current. Unfortunately, an inrush current is

a higher than normal current, so it can often be diﬃcult to select protection equipment such that it adequately protects the installation but doesn’t trip when a motor starts or a transformer is energised. The second category of problem involves voltage dips. If you draw current from an electrical installation, the voltage supplied to the loads connected to that installation will inevitably fall. This is

THE CPD ZONE

thanks to Ohm’s law, the impedance of the cables and other factors like the impedance of the transformer feeding the installation. It stands to reason, therefore, that if you draw a large inrush current, the voltage drop will be higher than in steady-state operating conditions. This sudden reduction in supply voltage may just make the lights flicker, which is annoying but not necessarily disruptive, or it may adversely affect the operation of computers and other electronic equipment, which is likely to be much more problematic. There are two key takeaways from this particular discussion: a) inrush currents are everywhere, and b) they can be a source of trouble. What’s to be done? Well, the first step, as always, is to gather reliable and accurate data about what’s really going on, and that means making measurements of the inrush currents in your installation. But before you do this, there’s something you need to know: a number of instruments that claim to offer inrush measuring capabilities don’t always provide the full picture. The problem with these instruments is that they can only measure inrush from a

‘standing start’ – in other words, in a system that is initially powered off. This can be very inconvenient, and in most cases, it isn’t a true representation of what happens in real life, where a load that produces an inrush current is most likely to be connected to an installation that’s already live. True to form To address this limitation, Chauvin Arnoux is now offering instruments with a True InRush function. As easy and convenient to use as ordinary clamp meters, these instruments can measure the initial inrush current when a specific load is connected to the installation, whether or not the installation was already powered, and can also measure subsequent inrush events caused by connecting further loads to the installation. To deliver this functionality the instruments use a novel measurement algorithm. First, this captures the steady-state current for the installation, which it filters to remove anticipated normal variations, producing an RMS reference current. Then it carries out half-period monitoring, calculating the equivalent RMS current for every half cycle of the supply. If this exceeds a user-defined

60 November 2023 PROFESSIONAL ELECTRICIAN

threshold, which is an indication that an inrush event has occurred, the instrument starts making measurements every millisecond, and this continues for a total time of 100 ms. At the end of this time, the results are processed digitally to calculate the true inrush current for the period. The graph (pictured, left) gives an overview of this procedure. The accurate and realistic inrush data provided puts you in a position to easily identify any problem areas of your installation, and also any problem loads. Once these issues have been identified, remedial measures can be put in place. These are outside the scope of this article, but could, for example, include installing a soft starter or a variable speed drive to control a motor rather than using a conventional electromagnetic starter, or upgrading protection devices so that they’re no longer prone to tripping by the inrush currents, but still provide a satisfactory protection function. When the appropriate remedial actions have been taken, the final step is to confirm that all is now well by repeating the inrush measurements. In fact, it is advisable to routinely repeat the measurements, along with other key power quality measurements, at regular intervals to ensure that the performance of the installation is always optimised, and to provide warnings of any developing problems. As we’ve seen, determining the true value of inrush current in your installation is straightforward – providing that you use the right instrument.

make their way into the everyday home, electricians can also capitalise by actively seeking accreditations for low-carbon solutions like solar panels (PV), heat pumps, and electric vehicle (EV) charging stations. By doing so, professionals can meet the growing demand for sustainable options, securing more projects and expanding their client base at the same time. Electricians will also differentiate themselves from their peers, by being better equipped to address the energy challenges of end-users, homeowners and home builders. Offer apprenticeships Business owners should also re-invest in their workforce by offering apprenticeships that ensure a fresh stream of talent, while also providing valuable training opportunities to keep their existing staff ahead of the curve. By staying up-to-date with the latest innovations and industry standards, electricians can enhance their reputation and attract more customers. Turn to industry leaders Collaborating closely with industry leaders in training offers electricians a unique advantage. By fostering strong ties with these figures, they gain invaluable insights into the ever-evolving regulatory landscape. This partnership not only ensures their compliance with the latest standards but also provides them with a comprehensive understanding of which companies are at the forefront of these regulations. Pioneering the EV/PV revolution The rise of electric vehicles (EVs) and photovoltaic (PV) systems has revolutionised the energy landscape, providing electricians with a unique opportunity to lead the charge. For the EV industry, electricians can provide expert insights on charging infrastructure, installation, and maintenance. In the PV segment, electricians can showcase their expertise in solar panel installations and integration with smart home management systems, ensuring energy is used and stored at optimal times.

This also extends to the management of the added electrical load arising from the growing adoption of EVs and renewable energy sources, already an area of utmost concern as the move towards net-zero homes gathers pace. Managing the extra load With the increasing adoption of EVs and renewable energy sources, electricians must address the challenge of managing the extra load on electrical grids. The integration of electric vehicle supply equipment (EVSE) and smart panels can help homeowners and businesses optimise their energy consumption while ensuring grid stability. Electricians should be knowledgeable about advanced load management systems and energy storage solutions. By offering building and homeowners comprehensive consultations on the benefits of smart panels and energy-efficient practices, professionals can empower them to make informed decisions about their energy usage. Thinking outside of the (fuse)box An effective marketing and web presence is a powerful tool for electricians to reach and engage with potential clients. The cornerstone of marketing success lies in a well-optimised business website. By deploying keywords and local SEO strategies, electricians can improve their visibility in online searches. Social media platforms, such as YouTube, Instagram and even TikTok, can also facilitate direct interaction with

A CASE IN POINT: KIMBLETECH ELECTRIC Established since 2011, Kimbletech is a family-run renewable energy focused electrical contracting business based in High Wycombe, Buckinghamshire. Founded by Mechanical Engineering Graduate (and self-confessed “renewables nerd”), Chris Sadler, the company is all about passion, personal touches, and ﬁve-star customer experiences. Although Chris originally established the company as the sole electrician, the last decade has seen him develop a team of diligent installers and attentive support staﬀ.

066_PE_NOV23_Layout 1 05/10/2023 16:11 Page 2

Out with the old and in with the ‘renew’ At the beginning of 2022 Chris shifted the company focus into renewable energy, dedicating his time to researching the best existing and emerging innovative technologies. In an ever-advancing world with new scientific discoveries to assist this change, Kimbletech wants to be a driving force that rapidly delivers planet-saving technologies into homes across the UK. As such, it is now equipped with the skills to offer solar, EV charging and smart home installation/maintenance services to customers. Although Chris now oversees a thriving, healthy business, this has not always been the case, as he explains: “It was around 18 months ago that we joined Trade Mastermind and, although I had what I believed was a great idea for the business to branch out into greener services and technologies, like so many company owners, I was struggling to see the wood for the trees. “At this stage we were turning over around £20,000 per month and really struggling to turn a profit. Fast forward to today, and thanks to the help of Trade Mastermind, we’re turning over around £150,000 per month, which is a massive increase. At the same time, we’ve increased from eight staff to 17, and have upgraded from three vans to eight.” He continues: “From a personal perspective, I was able to come off the tools over a year ago, which makes a huge difference when it comes to focusing on running the business and it’s amazing how the company’s growth attracts people – lenders want to give us money, wholesalers want to give us credit, suppliers want to work with us, installers want to work for us, salespeople want to sell for us. Recruiting is

a much easier process. “As an individual, my mindset has completely changed. I make quicker decisions and I’m no longer afraid to step outside of my comfort zone.” A lasting Legacy Kimbletech’s involvement with Trade Mastermind has evolved over time, with Chris and his team now beneﬁtting from the ‘Legacy’ package of support, which involves 1-to-1 coaching sessions, a podcast package, monthly ‘Masterminds’, event access, accounts management, access to future training and marketing support – all of which help to contribute to and improve the skills of the individuals working in the business, along with the business itself. Chris says: “If I had just one piece of advice to share with others who may be struggling to control and/or grow their business, it would be to get yourself a mentor. The initial training that we undertook with Trade Mastermind helped to unlock my potential, but it’s been Joseph and his team that have been instrumental in keeping me on track. They’re also not afraid to tell me the hard truths when I need it. “I’m grateful to be on this journey and to be part of the overall Trade Mastermind legacy.” GET MORE DETAILS ABOUT HOW YOU CAN SIGN UP TO TRADE MASTERMIND BY VISITING: WWW.RDR.LINK/EAW026 WATCH KIMBLETECH’S TESTIMONIAL VIDEO CASE STUDY BY VISITING: WWW.RDR.LINK/EAW027

FIGHTING THE COLD WAR Peter Dumigan, MD of the Hultafors Group UK, oﬀers some pointers to professionals that are looking for work clothes that can brave all elements this winter. hen the weather takes a turn for the worse, it’s time to make sure you suit up with clothes that work as hard as you do – properly designed, sustainable working clothes that have got what it takes to keep you warm and dry whatever you’re doing on-site – inside or out. This winter, workwear choices will be as much inﬂuenced by sustainability as they are for comfort, practicality and protection. Many tradesmen and women are now buying better-quality garments that will not only last longer but

incorporate recycled ﬁbres in the fabric technology which helps to reduce environmental waste. If you’re wet or cold, you’re not going to be working as eﬃciently and comfortably as you could. That’s why wearing layers is the best way to maintain comfort and regulate your body temperature, especially when you’re working in unpredictable or generally inclement weather conditions. A three-layer workwear system – Base-layers, Mid-layers and Outer-layers – will keep you warm and comfortable by transporting moisture away from your skin,

insulating your body, and protecting you from cold, wet and windy weather. All about the Base Whether it’s hot or cold, the key to eﬀective layering is making sure you stay dry, even when you’re working up a sweat. The best way to do just that is through the layer that’s closest to your skin – the Base-layer. These undergarments, including socks, are vital for staying dry and ventilated and the types you wear should ‘wick’ (transport) moisture away from your skin. The range of Base-layer clothes from

Snickers Workwear have seamless comfort and a great ergonomic fit, but different garments’ fabrics, such as those with ‘37.5 technology’, provide different levels of ventilation and warmth depending on how active you are while working and the weather conditions you’re working in. During the colder months of the year, Merino wool is a natural and durable Base-layer choice. While it can absorb around 5% of its own weight in moisture, this type of wool has the added benefit of being naturally odour resistant – and it’s environmentally friendly too. Catching the Mid-drift If your job involves moving back and forth, indoors and outside, or you find yourself constantly switching between physical and stationary tasks in colder conditions, t’s worth paying particular attention to your choice of Mid-layer clothing. Your second – middle – layer is designed for warmth and insulation and to compliment your base-layers. If it’s ergonomically designed for a body-mapping fit, it should trap your body heat in a pocket of warm air around you. That means your Mid-layer needs to fit

well, without being too tight or loose. Ideally, it will be made from a knitted, quilted, fleece, or microfleece materials that provide an airy yet comfortable enclosure. However, if your work is physically demanding, ventilating your body is vital and this is where garment functionality is absolutely crucial. You’ll need ‘Hybrid’ garments that provide insulation combined with ventilation and multiple functionality features like Snickers Workwear’s fleeces, gilets and lightweight jackets which are made from more environmentally friendly fabrics such as recycled polyester. Outer this world If you have to work outside in cold, wet, or windy weather for long periods, work will get even harder. That’s when you’ll definitely want to protect yourself from the elements with your own protective shell – the third weatherproof Outer-layer. Your third layer needs to deliver effective wind and water protection to keep you warm, dry and to ensure the effectiveness of the two inner layers. And as with both Base- and Mid-layers, you’ll want to avoid getting too warm – so insulation combined with ventilation features in your outer garments are absolutely vital. That means that you need jackets designed to be durable and weatherproof which complement the garments’ overall technical functionality. Snickers Workwear’s work jackets are built to be weatherproof enough to keep the elements at bay, and durable enough to withstand the wear and tear of a hard day’s work.

STAY DRY AND MIGHTY There are some key things to consider when dressing for wet weather work: l

For 100% waterproofness and a full day’s high-intensity work, choose a breathable waterproof garment with taped seams for maximum protection and breathability. For 100% waterproofness in low intensity work in pouring rain choose a PU garment with welded seams. For a basic protection against water choose a garment that is water-repellent. The garment will keep you dry if it’s drizzling but still offers breathability. Look for garments that are certified for performance and effectiveness to the certification standard EN 343. Don’t forget that what you wear underneath your outer layer really matters, so think about comfort and breathability features.

Don’t forget about ventilation! The breathability of your clothing layers is just as crucial for your comfort, so make a habit of checking the breathability features of the fabric in the garments you buy to ensure that the fabrics transport sweat away from the skin. Breathability comes in two ways: either the breathability of the fabric itself, such as 37.5 technology sports fabric, or built-in ventilation functionality such as zippers or meshed fabric areas at the sides and back of the garments.

DESTINATION SUSTAINABILITY strong sustainability approach is vital to ensure businesses are doing their bit to effect global change. At Hager, the strategy is focused around three core streams: a) ethics, b) employees and c) environment. While the ultimate motivation has to be enhancing sustainability efforts because it’s the right thing to do, there are other secondary factors. Many customers are now demanding greener solutions as part of their own efforts towards sustainability, and ultimately the eco-credentials of a supplier are now considered alongside cost and quality when it comes to purchasing choices. So, sustainability is good for business and clearly good for the planet – but there’s also a benefit when it comes to company culture. Working for an employer which places a high value on the local community, the

global community, and even future communities, is becoming increasingly attractive – meaning those with effective sustainability plans are more likely to recruit and retain good candidates for vacant roles. This is becoming ever more pertinent as new jobseekers join the workforce: Global Tolerance found almost two-thirds of millennials wanted to work for a company which made a positive impact on the world. So that’s the motivation to do so, but how does a company go about creating effective change and help achieve ambitious targets (like the 78% reduction in greenhouse gas emissions the government is looking to reach by 2035)? Products in practice At Hager UK’s Telford base, all lighting is now LED – achieving an impressive 97% energy saving, supported by the introduction of sensors so lights are only used when necessary. EV chargers have also been installed to help support staff members’ use of electric vehicles, as well as the transition of Hager’s own fleet to plug-in hybrids and EVs. Alternative paint has been introduced which cures at 180˚C, compared to

With sustainability being a core focus for businesses that are environmentally conscious, there is one thing which is abundantly clear: the time to take action is now. The team at Hager UK shares some of the work it has been doing to help make a real difference. the 220˚C heat required by traditional powder coating materials – and insulating the ovens will improve energy use even further. Future increases in reliance on solar power will see Hager’s demand on the grid further reduced by 35%. Other renewable energy solutions plus reductions in water usage (both fresh and waste water) are under discussion. A Group effort This is backed up by the wider Group’s sustainability efforts, including but in no way limited to: sourcing and using materials considerately, achieving industry accreditation where feasible, and working towards improving product life cycles. Yet there’s a recognition that, no matter how effective Hager’s changes are, the scale of the change needed requires all businesses to be on board. It’s this vision which has inspired the launch of the Blue Planet Commitment (BPC). The Commitment not only details the work Hager is doing – and will continue to do – as part of its vision of sustainability; it outlines how the company can work alongside suppliers, contractors and end customers to maximise the positive effects they’re having. After all, sustainability isn’t something a company is able to ‘complete’ and then move on to the next aim. Instead, it’s a longer term journey.

WATT’S THE fuss about lumens? Russell Parr, CEO at PowerLed, explains why adopting lumens as a metric can reduce energy costs, lower CO2 emissions and lead to smarter purchasing decisions. ith the fast-paced evolution of lighting technologies like LEDs, precision in measuring brightness has become paramount. For electrical contractors, understanding the value of using lumens instead of watts is essential.

Why focus on lumens? For decades, wattage has served as the standard marker by which the brightness of a bulb has been judged. Everyone could take for granted that a 100 W bulb was brighter than a 60 W bulb. Wattage, however, is a measure of energy usage not brightness, and today, with the advent of energy-saving solutions like LEDs, it no longer provides accuracy when evaluating brightness. Lumens, on the other hand, is the standard measure of brightness and as such offers a clearer picture of an LED's performance. Industry pioneers, PowerLed, see the shift to lumens over watts as vital in helping electrical contractors and consumers take full advantage of the benefits that the latest LED technologies have to offer, enabling them to achieve ideal lighting conditions while simultaneously improving energy efficiency and sustainability. Illuminating the path forward PowerLed has been developing pioneering lighting solutions since 1995, combining expertise, research and market knowledge to launch innovative new products.

Powerled’s new +Flex LED tape, for example, significantly outperforms basic LED flexitape when comparing the brightness generated to the power used. Similarly, its modern floodlights produce the same luminosity achieved by previous models but with a significantly smaller wattage. Given the company is constantly evolving new products that give greater luminosity per watt, this strengthens PowerLed’s position for using lumens rather than watts when choosing the most efficient lighting solutions. The company’s expertise in power technology and large-scale production has led to the development of innovative, constantly evolving LED solutions with ever-increasing efficiency and reliability. The extensive range of intelligent, commercial LED lighting options feature quality components and next-gen technologies and can be deployed across a broad spectrum of retail, commercial and industrial applications. The PowerLed range of LED power supplies is suitable for both interior and exterior installations and in addition to compact sizes, power factor correction, high efficiency and isolated or non-isolated design, features unique benefits. Its LED drivers are CE approved, comply with UK, EU and international safety certification, and come with warranties of up to five years. Equally important for PowerLed is quality assurance. While some producers have been known to use testing conditions that can exaggerate lifespan, PowerLed carries out extensive testing

74 November 2023 PROFESSIONAL ELECTRICIAN

during the assembly process to ensure accurate lifespans are provided. Moreover, the focus is on warranty, rather than operational hours, giving contractors increased conﬁdence in the products. Staying ahead of the curve For electrical contractors wishing to stay ahead of the curve, understanding the shift from watts to lumens is essential when choosing the right LED lighting solution. With specialists like PowerLed focusing on providing solutions that deliver increasingly more lumens per watt, contractors that adopt the lumens metric will be better positioned to help their own customers.

We put the questions to Gavin Hamilton, Sales & Marketing Director at Hamilton Litestat, to learn more about why the latest additions to the Verve white plastic range will be a sound investment. Hamilton has recently announced two additions to its Verve white plastic range. Tell us more about them. The ever-growing reliance on smart devices within the home, coupled with the demand for versatile living spaces, has fuelled Hamilton’s latest product development initiative, resulting in the introduction of two new additions to the Verve white plastic range.

Enhanced USB charging Hamilton’s new ultra-fast combined USB-A 2.4 A & USB-C 3 A double switched sockets (4.8 A total) provide a faster and more convenient way to simultaneously charge laptops/tablets and mobile devices. This complements the existing ultra-fast dual 2.4 A USB-A (4.8 A total) double switched socket.

WHITE IS JUST RIGHT terminals with clearer markings. Both the standard 100 W and the newly released 250 W LEDITB dimmers feature a soft start up and down feature. This enhances lighting control for a smoother experience and extends lamp life, while their built-in thermal circuit protection safeguards against overheating. With consumer demand for ‘smart’ and convenient products and solutions increasing, what role do sockets with advanced capability and LED dimming technology play in this product mix? Smart homes, although topical, are still out of reach for many. However, with the option of improved charging, and

Expansive LED dimming Hamilton’s new 250W LED 2-Way rotary dimmers offer 2.5 times the dimming capacity of the standard 100 W dimmer in the range. Compatible with a wide range of LED lamps and luminaires, the LEDITB series offers two-way dimming, making it an ideal choice for rooms with two entrances/exits. The increased capacity makes the LEDITB250 ideal for larger spaces with more lighting, or more complex lighting schemes. Are there any features/benefits offered by both products that are particularly unique?

advanced LED dimming technology, homeowners can take a step towards a ‘smarter’ home. This transformation is particularly timely as the modern shift towards remote work has blurred the lines between home and oﬃce. The Verve range has responded by providing enhanced functionality, reﬂecting the dynamic needs of the modern homeowner/worker. With both products forming part of the Verve white plastic range, why is that white plastic is proving a popular choice at this moment in time? Across the industry, the conspicuous surge in demand for white plastic accessories has not gone unnoticed.

076_PE_NOV23_Layout 1 05/10/2023 16:20 Page 77

Intriguingly, the current cost-of-living challenges have led to increased use of white plastic in numerous projects.

KAMM IS ‘MINT’ hino Products is already well known to trade professionals up and down the country. The company has been helping individuals to maximise their vans’ storage capabilities for two decades, having celebrated its 20th anniversary in September of this year. Upholding its strong principles of quality and innovation, Rhino has overhauled its entire roof rack and bar range, built upon the hugely successful KammBar. This latest family of products has been launched as the Kamm Generation.

The Kamm Generation A complete game-changer in terms of design, each of these new products use the same ultra-aerodynamic teardrop shaped bar profile used on the original KammBar. This means that the entire range also benefits from the fast fitting, pre-assembled leg design that allows users to fit the products in record time. One of the strongest roof bar systems on the market, Rhino’s KammBar Fleet has a stylish and practical design that

enhances both the appearance and storage capabilities of any van. The high-tensile alloyed steel bar has the unique teardrop shape that reduces drag and fuel consumption, along with an inorganic zinc topcoat seal, which protects against even the harshest of weather. Ultra-aerodynamic, stylish, and corrosion resistant, the KammBar Pro is the premium roof bar of choice for van users. The anodised aluminium finish delivers the highest possible protection against rust and corrosion, whilst also giving the bar a sleek, modern look to complement your van. The next product to join the Kamm range was the KammRack, benefitting from the ultra-aerodynamic ‘Kamm’ bar profile, making it Rhino’s quietest rack ever. The product also shares the fast-fitting, pre-assembled feet. This, coupled with the ‘click together’ side frames and crosstubes, means it is easy for one person to fit. Filling a ‘black’ hole The development of the Kamm range doesn’t stop there, however, as 2024 will see the launch of the KammRack Black, providing the same stylish roof rack in powder coated black with an aluminium roller, and further complementing today’s modern commercial vehicles. All of the Kamm Generation products are compatible with Rhino’s full range of accessories,

Following last year’s introduction of the Kamm Generation of van accessories from Rhino Products, we catch up with the company’s CEO, Steve Egerton, to find out more about the way installers can benefit from this increasingly well-known range. including the iconic PipeTube Pro. Both the KammRack and KammRack Black are supplied with a strong anodised aluminium rear roller. Complementing the KammBar Fleet and the KammBar Pro, is the upgraded, lightweight yet durable aluminium roller. Lighter than Rhino’s previous rear rollers, the company has managed to substantially reduce the weight of the product without compromising on its strength. Every member of the Kamm family has been refined – even Rhino’s Kamm load stops have had a complete redesign, decreasing wind noise and drag. The company’s most recent release, the MR4 Modular Racking range, is its first internal product to-date. With a whole host of accessories and configurations available, MR4 internal racking systems allow the user to customise their van to their specific needs. The strong, yet lightweight high tensile steel systems come with bespoke fitting kits for every vehicle, providing the quickest and easiest fitting process possible.

‘EPIC’ PROPORTIONS Following the launch of a new App which aims to help both electrical professionals and end user customers to manage prospective jobs in a much easier way, we talk to electrician and inventor, David Evans, to find out more about his ‘Epic’ idea. David, before we talk further about Your Epic Home, tell us more about your background in the electrical industry. I started my electrical industry career after leaving school in the early 2000s and worked as an apprentice for local businesses. After gaining some experience I went on to work on Heathrow’s Terminal 5 and eventually started my own business – Epic Electrical – in 2006, which provided me with the opportunity to work all over the world.

How did the idea for the Your Epic Home concept first come about and what has the development process been like? I’d long wanted to find a solution that could make the process of managing domestic jobs easier, so contractors wouldn’t find themselves bogged down by paperwork and administration. The development process behind Your Epic Home was a bit slower than I’d originally hoped for, mainly because of the time it’s taken to get all sides aligned with terminology and the different processes that need to be done to make the App function correctly.

How does the Your Epic Home concept and App work? The concept is just like an MoT for your car but instead applies to your home. Customers are able to ﬁnd the service they need undertaking within their

property, can choose a date that is suitable to them and will know exactly how much they’re going to pay. They’ll then be able to keep all the certiﬁcation for the property within the App and, should they sell the property in future, they can then transfer the documentation to the new homeowner using a one-time passcode. From a contractor perspective, they’re able to use the App to easily and quickly inﬁll their diaries and have the reassurance that they will get paid out within 5-7 days of the job. This removes any outlay for materials and also means they don’t have to chase the customer for payment or spend the evening undertaking paperwork. Which types of individuals and businesses would the App suit best? For us the App is about ensuring customer safety within their home. It is therefore an ideal solution for homeowners, tenants, landlords, housebuilders and estate agents. We’re also looking at its use within social housing and housing associations.

Are there any costs and subscription fees involved? Currently the App is free to download for both customers and contractors. The only time there is a subscription charge is if someone has more than two properties, but the charges are minimal and increase with the more properties they own.

80 November 2023 PROFESSIONAL ELECTRICIAN

What sort of impact do you hope that the App launch will have on the electrical industry? We’re hoping that the App will have a positive impact, not just across the electrical industry but also throughout other sectors as well. Contractors will have a platform to use that is free and will allow them a quick way to gain work to ﬁll in any gaps in their diary. In turn, the quicker payment process will help their cashﬂow. Additionally, contractors can pick jobs local to them which will help with their overall green footprint.

MAKING A BRACKET PE catches up with the inventor of a new solution that aims to improve the process of securing electrical metal back boxes. he newly developed Box Strap Bracket is speciﬁcally designed to secure electrical metal back boxes, ensuring a safe and eﬃcient installation. The bracket is an alternative to the traditional telescopic bracket, which is also known as ‘caddy strap’, and was invented by an electrician.

The origin of the idea Josh Estrada, the brains behind the product, explains more about where the inspiration came from: “The idea originated after encountering some jobs where I had little-to-no access to the stud work behind the plasterboard due to materials being in the way or an alteration to an existing installation. “The clients in question did not want to use a plastic drylining box (as they’re a combustible material), and the lip of the plastic box prevents the electrical switchgear from sitting ﬂush with the wall.” He continues: “The bracket is fixed from the front of the plasterboard cut-out for a switch or a socket and is fixed on the plasterboard with two drywall screws. This differs from the traditional method that requires you to go behind the wall to install the

telescopic bracket between studs. “It’s that easy to install, we’re confident that experienced users could see their installation times improving significantly over more traditional methods.” Looking specifically at the benefits for electrical contractors, Josh believes there are many, stating: “Firstly, it will put a stop to earth parallel paths during R1+R2 testing, as the metal stud work that is causing the earth parallel paths in a new build installation doesn’t come under an exposed-conductive-part or an extraneous-conductive-part as the bracket can also be installed vertically to avoid having to cut it. This also means there is no requirement to cut the brackets to fit in between studs. “Additionally, contractors don’t have to cut or trim plasterboard that has been ‘overboarded’

over the back boxes by the drylining contractors, as the cables can be left inside the wall and the boxes cut out when the open side of the wall gets closed. Now you simply install the metal boxes without having the stud work exposed.”

Peace of mind Of course, the process of bringing a product of this ilk to the marketplace is one that involves a significant amount of safety testing to ensure it is fit for purpose. To that end, Josh has got his ducks nicely in a row by undertaking proof testing ahead of the product’s launch. He says: “We have some significant certification behind the product and have conducted pull tests to ensure it meets the requisite requirements. The results are freely available on my website for any interested parties to have a look at. “Equally as significant is that fact that Hilti has approved the installation method to be compatible with its CP617 putty pads, so that is great news.” Josh concludes: “It’s amazing to see the product come to life and I’m keen to make sure that it is readily available throughout the whole electrical supply chain network. We’re currently in talks regarding new electrical wholesalers coming on board as distributors and I’ll be demonstrating the product at various trade shows in the future. I’m confident it will prove to be a useful solution for those who use it.” GET MORE PRODUCT AND PURCHASING DETAILS ABOUT THE BOX STRAP BRACKET BY VISITING: WWW.RDR.LINK/EAW035

A VERY WORTHWHILE FLEX-ERCISE Pete (Monty) Monfort, Director at Arena Training Centre and Monty Electrics (along with a little help from his students), reviews the Chauvin Arnoux Digiflex MA400D. received the Chauvin Arnoux Digiflex MA400D by post and when the tiny package arrived by courier I was momentarily left wondering what an earth I had ordered. Upon opening the package I was pleasantly surprised as it revealed a robust palm-sized current tester that will easily fit in my tool bag or pocket. The MA400D is really simple to use. It has two buttons – On/Off – and another button that can hold a measured value or, with a slightly longer press, will put it into maximum value mode allowing a current

reading to be monitored over time and the highest value recorded. The really cool thing about this device is the current reading clamp which is made from a piece of flex. This means you can literally thread it round a cable where a traditional solid clamp meter would have no chance of reaching. I tried this on a few installations and on one example a set of meter tails which had been very tidily bound together with hardly any slack between them was easily measured with the slim flex being threaded between the cables. The flexible loop has a clip to stop it coming undone and a handy little release button to allow it to be disconnected. It is powered by 2 x AAA batteries and the auto-off function should mean that the batteries will last ages. You can also stop the auto-off function, allowing you to install the device,

something that is useful if you want to leave the device monitoring for a longer period of time. One for the Christmas list The MA400D measures AC current from 20mA up to 400 A and there is another model which will measure up to 4,000 A. Don’t worry about sticking your hands into live boards either, as you can safely isolate, install the device and put it into max mode before re-energising and leaving it to measure for a period of time. You can then power down and safely retrieve the value measured. I introduced our apprentices to the MA400D and it took them around 60 seconds to work outs its use, allowing them to carry out a test on a specialist teaching rig in our workshop. With a more than reasonable price tag, its tiny pocket size, ease of use and ﬂexible loop, this should be on everyone’s Christmas list this year.

SMART TECHNOLOGY The Theben iON 102 KNX push-button with integrated temperature sensor.

The ‘Party Barn’ entertainment space by New Land Projects.

EMBRACING THE FUTURE The experts at KNX UK identify some of the latest smart home automation trends and user demands. he concept of a ‘smart home’ is no longer confined to science fiction or high end luxury homes. Home automation has become an integral part of modern living, enhancing convenience, security, and energy efficiency. As electrical professionals, staying abreast of the latest smart home automation trends and understanding the technology, settings and scenes that homeowners desire can help provide superior services to your clients. So, let’s explore some of the features and scenes that homeowners are increasingly requesting to enhance their lifestyle:

Good morning routine Imagine the bathroom heating turns on at 6am. A few moments later the room is at the perfect temperature. At 6:30am the blinds in your bedroom are gently raised. Your favourite news program automatically comes on the TV or radio. Automating your clients’ morning routine can greatly enhance convenience and energy eﬃciency, as well as making sure they start each day energised and well-informed. Comfort adapting thermostats Thermostats have evolved to adapt to temperature preferences and daily routines, ensuring the living space remains consistently comfortable.

Intelligent thermostats learn daily patterns and temperature preferences, then use the data acquired from your interactions with the thermostat to anticipate when you’ll return home, when you’ll be asleep, and when you’ll be away. Over time, these intelligent thermostats become tuned-in to your unique preferences and autonomously fine-tune the temperature settings, guaranteeing comfort without requiring manual intervention. Entertainment scenes Our integrator members say that their clients love the convenience and ‘wow’ factor that entertainment scenes offer. These scenes encompass automation options such as effortlessly dimming the lights, drawing the curtains, and activating the TV and sound system for a captivating movie night. They can also craft an ambient atmosphere with gentle lighting and harmonious music for a memorable dinner party. Picture a 'party' scene that sets the mood with a simple button press, featuring tailored lighting that illuminates the home’s key decor elements and automatically plays a custom playlist. Intelligent energy management An increasing demand for automation settings that optimise energy consumption by adjusting heating, cooling, and lighting based on occupancy and time of day reflects a broader societal shift towards

88 November 2023 PROFESSIONAL ELECTRICIAN

eco-conscious living and sustainability. The advanced systems that our integrators are increasingly installing adjust various parameters such as heating, cooling, and lighting based on factors like occupancy and time of day. Dynamic lighting scenarios Imagine waking up to the gradual emergence of sunlight as your automated blinds open in the morning. Equipped with sensors, automated window blinds adapt throughout the day to maintain an ideal level of natural light, reducing the dependence on artiﬁcial lighting. For instance if the natural light falls below 40%, the automated lighting increases to 60%. This is perfect for darker evenings and overcast days, and for conserving energy during the lighter days of summer. Intelligent integration The ideal smart home ecosystem is one where all devices seamlessly communicate with each other, regardless of their manufacturer or built-in technology. Electrical professionals are increasingly asked to create systems that bring together various brands and protocols to create a cohesive automation experience. To this end, KNX is the only worldwide standard for intelligent home and building controls. Products that work using the KNX language are made by diﬀerent manufacturers and can be

WHAT’S THE MATTER? Stephen Payne, Eltako UK Sales Manager, looks into some of the reasons why ‘Matter’ could change the smart home market. t’s not often that something new comes along that will have such a big impact on the smart home market, in the way that Matter will. Previously called Connected Home Over IP (CHIP), it was designed to bring together tech companies, manufacturers and IoT platforms to give true smart home interoperability. A good number of manufacturers, including Google, Apple, Amazon, ABB, Legrand and Eltako are already on board with this development, with Version 1 of the Matter speciﬁcation launched at the beginning of November 2022. The software is truly Open Source, and the only requirement is to register and consent to the terms and conditions. Manufacturers then need to have their Matter products independently tested and approved to assure complete interoperability.

Professional installation requirement Matter devices can be controlled via both wired switches and Wi-Fi App and will open a whole new world of possibilities for homes to become truly integrated and intelligent. Eltako has initially launched four devices, for switching and dimming lights and controlling blinds. As well as working with Matter, they can be integrated into, and will work with, Apple HomeKit, Google

Home and Amazon (Alexa) with the free Eltako Connect software allowing you to make the conﬁguration. The Eltako modules will need to be professionally installed, which means that UK electricians will be able to install smart controls into properties with the minimum of fuss. Switching devices can be standard UK switches or retractive-switches, which can be purchased from any wholesaler and come in many diﬀerent designs (not just white). In general, once the devices are installed and powered up, you will hear a tone after a few seconds. After scanning the correct QR code supplied, the device is then added to the selected App. You then select a name for the device (for example, ‘Lounge Lights’) from a drop-down box menu or you can type in

90 November 2023 PROFESSIONAL ELECTRICIAN

your own selection. Any updates are downloaded automatically and it should be noted that the software is encrypted and totally secure. Once the devices are integrated to make a system and conﬁgured via your chosen App, they can then be controlled via wall switch, over your smart home App or by voice control. Assisted Living potential Matter will also open many possibilities in the Assisted Living sector, allowing the use of PIR sensors so individuals can see where they are in their home, whether their door is locked at night, if the temperature of the room is correct, and so much more. These things are already possible with Eltako’s wireless devices, but now there will be an alternative wired/Wi-Fi

090_PE_NOV23_Layout 1 05/10/2023 16:27 Page 91

solution, giving installers more choice. There are already over 1,200 devices listed for heating, lighting, blinds, air quality, access control and leak sensors that work with Matter, with some devices requiring professional installation and

others a more plug and play approach. Because Matter is an Open Protocol, you’re not dependent on one single manufacturer, so you can simply pick and choose the products you want from the various existing manufacturers. This will also keep the Matter market competitive, which is good for everyone. For installers and distributors this opens a new and lucrative revenue stream, without the need for investment in expensive commissioning equipment or training. For the homeowner it oﬀers them the capability of smart control without a

high price tag and little or no disruption to their home. You could start with one room or the whole house and take away or add devices as you need. Eltako also oﬀers an open API for anyone who would like to conﬁgure and control the new IP devices from Eltako with their own software. Information on this can be downloaded from our website. Smart homes for everyone It has long been the market’s desire to easily integrate all the smart devices in a home together using one Open Protocol. Matter will help to achieve this ambition, bringing all the devices in a home together and putting the smart home concept within the reach of just about everyone.

DIPPING THE TOE Andy Douglas, MD at Timeguard, examines the benefits of Wi-Fi integrated devices for customers who want smart control without significant expense. o one can deny the attraction of a fully automated, integrated home to deliver top levels of eﬃciency and ease of living. Installers are clamouring to acquire the skills they need to deliver real intelligence in building control, and employers are playing their part in supporting skills development with initiatives like CEDIA’s NextGen. Meanwhile, most of our homes aren’t currently geared up for advanced home automation. High-end integrated control, where devices work in harmony with each other, usually requires rewiring that involves going beyond adding a neutral to the switch outlets and adding signiﬁcant cost to a project. You might imagine that any new build or recent rewiring would already be smart tech-ready, but don’t

bank on it just yet. So, what is the appropriate technology solution for customers who want smart control without the major expense? The answer is good quality Wi-Fi technology, combining reliable products and a consistently reliable third-party control App like TuYa (manufacturers’ own Apps may be limited and might not have the development ﬁnance of a global platform like TuYa to maintain reliability and add new features). A catch-all solution Wi-Fi has proved to be the ideal answer, giving App-based control of devices from within the home or anywhere in the world where you have an internet connection or Wi-Fi signal. Bluetooth, Zigbee etc. have a role in some projects, but it is Wi-Fi that is the catch-all, covering all the bases to give users both close-quarters control and remote access. Popular Wi-Fi controlled devices include high-quality web cams, external lighting, detectors, timers, switches and wall sockets. On/oﬀ, time control, detection ranges etc. can all be controlled remotely via a smartphone from the armchair, on the commute home or at the holiday villa. Users will get feedback on switching status on their App, so they can relax, knowing that any devices

employed at home are continuing to do their job. Integrating other devices Product developers are meeting the demand for inter-working between devices on Wi-Fi networks. Indirect load activation, where the load is physically connected via the switched live, means that another compatible smart device can be triggered wirelessly. The new Timeguard Wi-Fi controlled twin LED floodlights offer this feature so, for instance, someone triggering the PIR detector could cause several other lights around the property – indoors and out – to switch on. Product grouping This is a useful feature for linking lighting circuits together wirelessly if the installer wants devices, such as lights and/or a room heater to switch on/off together at the touch of a button. Product grouping can be easily set-up within the TuYa App by creating a group. Yes, it’s a toe in the water exercise compared to mansions with home cinemas and the like, but end users love the flexibility and control offered by smart home Wi-Fi devices. More to the point, they’re also different and fun to install/set-up. BROWSE TIMEGUARD’S RANGE OF WI-FI CONTROL DEVICES AT: WWW.RDR.LINK/EAW042

LEAK PRACTICE Neil McCarry, Director at NM Controls, explores some of the ways that the latest technology can help to avoid those undetected disasters. s with all KNX installations that I undertake, I’ll always talk about the seamless 'interoperability' between the 500+ manufacturers’ products. Although it’s the back end where most of the clever magic takes place, the front end kit usually steals the stage, showcasing the many fantastic switch and touchscreen options available. A good example of this is the device showcased in my pictures – the Zennio UK Z35 capacitive touch panel – which is deployed in many hotel room settings.

Critical thinking One thing that is not normally in the forefront of discussions are the many devices that are used for the management of critical functions within properties, to provide energy management, safety systems etc. These devices will just sit there in the background waiting for something to happen before jumping into action when called for, automating the required actions within a room/building such as reducing heating 'set-points' or signalling

a water leak, as the featured device is doing here. This water leak detector from MDT technologies GmbH is a very robust device, ideal for installation in areas such as bathrooms and boiler rooms – anywhere that has a requirement for leak detection. A ‘true’ KNX device The MDT SCN-LSEN1.01 has all the required parameters that you would expect, such as 'auto reset' when dry or my preferred option – reset via manual intervention (the maintenance team, for example). We also have 'cyclic’ sending of alarms to ensure this is not missed. When Hitesh Vaghela, who represents MDT technologies GmbH in the UK, first introduced this device to me I was delighted to see that this was a true KNX device powered directly from the KNX bus. With no other components required, such as PSU, it is a very easy addition to the installation – whether it’s a new or retrofit requirement. If you look more closely at the images you’ll see the sensor pre-alarm and the touch panel in its normal state showing the thermostat. The sensor

100 November 2023 PROFESSIONAL ELECTRICIAN

then activates (local red LED indication) and the touch panel indicates via a 'pop up' message that a leak has been detected. This can be cleared from the screen but would re-activate as the sensor is sending the alarm cyclically. Of course, by utilising the Zennio UK ZBMS server we can send an e-mail notification to the maintenance team, so the client is always covered. Visit the NM Controls website at: www.nmcontrols.co.uk

A JOLT FROM THE BLUETOOTH Phil Brown, NVC Lighting’s Director of Product & Marketing, explains how Bluetooth technology is making the most reliable emergency test systems appropriate for an even wider range of projects. mergency lighting is required wherever the public has access to a building or where people are employed and in multi-occupancy facilities such as HMOs, student accommodation and care homes. Unlike most lighting, it’s not just a case of installing the unit and then it’s ‘job done’ as long as it’s working.

The insurance policy Emergency lighting is like an insurance policy. You hope you won’t need it, but it’s there just in case you do, so it must be reliable should the worst happen. This means that it needs to be tested every month with an annual full discharge test, typically for three hours per ﬁtting annually. That’s the law, by the way. There are three levels of emergency testing systems: manual, self-test and addressable self-test. Addressable self-test is the premium solution of these options. This is because testing is fully automated so it’s never omitted and done at zero cost. Testing can be scheduled to take place at an

appropriate time for the building occupants, for example avoiding teaching times in schools and performance times in cinemas. The test results are then automatically sent to the responsible person and put in a file to be checked later, as is the case if manual testing systems are used. Until recently it was hard for an electrician to up-sell a customer to addressable self-test solutions as they required a DALI network. And while these are still the right solution for many larger buildings, for some they’re considered too expensive to install and too difficult to commission. Now, that’s all changed… Easy and profitable installation The latest addressable self-test systems offer the benefits of automation, scheduling, and proactive fault reporting at a lower cost. Using Bluetooth mesh technology, rather than a wired DALI network, and an App on your phone or tablet, up to 42,000 emergency fittings can be linked in a single system. Testing is automatic and carried out to a

prearranged schedule with full test results available via the App, whenever it’s required by the responsible person. This is a solution that an experienced electrician can be confident to install not only relatively easily but also profitably. Addressable self-test was always a great solution – now it is lower cost and easier to install thanks to Bluetooth mesh technology. Addressable self-test systems using Bluetooth can be fitted across NVC Lighting’s wide range of commercial, industrial, and public sector lighting products, both in dedicated emergency fittings (such as exit signs) and in converted fittings, such as panels, battens, and downlights. It’s been a while coming, but finally we now have an addressable self-test emergency lighting system that is as profitable for the electrician to sell as it is for the customer to use.
