ECN February issue out now!

The February issue of ECN is OUT NOW and packed with insights and information on the topics you care about. Read the issue here.  From the Editor Making the headlines recently is an issue that continues to affect tradespeople: tool theft. There are growing concerns surrounding theft and the push for a ban on the sale of second-hand tools. The Trades United van rally in Westminster, which at the time of writing is just days away, is set to make waves. The event aims to urge the government to take stronger action against the increasing problem of tool theft. With a call for tougher laws and better enforcement, tradespeople will unite in protest, staging a ‘go-slow’ convoy to draw attention to the issue. In 2022, On The Tools published a white paper revealing that 78% of tradespeople had fallen victim to tool theft, and 94% of those stolen tools were never recovered. Sadly, the situation hasn’t improved, with 85% of tradespeople still fearing theft daily or weekly. Despite ongoing public concern, tools crucial to trades remain excluded from vital legislation like the Equipment Theft Prevention Act 2023. On The Tools is also championing public engagement by offering a pre-drafted letter to MPs, which can be downloaded from its website. In addition, recent research by Direct Line business insurance reveals that 67% of people support a ban on second-hand tool sales unless the seller can prove ownership. The resale of stolen tools through online marketplaces and car boot sales is a growing issue. Last year, 47% of tradespeople either encountered or were approached by someone trying to sell suspicious tools. Of those, 92% refused to buy and 56% reported the incident. Although last year’s rally received widespread political attention and promises of support, tangible progress remains elusive. With this latest rally, we hope the government will take meaningful steps to address the crisis and better protect tradespeople’s livelihoods. Back to the ECN February issue, this month’s features include Fire, Safety & Security, Power/Renewables/Solar, and Wiring Accessories, and in our interview I discuss driving renewables and shaping a greener future with MCS’ Ian Rippin. Plus, don’t miss out on the chance to win a product bundle worth over £200, courtesy of WISKA UK. I hope you enjoy the issue – see you next month! Carly Weller Group Editor

Update to EAS Qualifications Guide: New standards and categories

To support the release of the latest Electrotechnical Assessment Specification (October 2024), The Electrotechnical Skills Partnership (TESP) has worked with the EAS Management Committee to update the EAS Qualifications Guide. The guide reflects the changes made in the EAS to drive up standards and focus on competence and identifies the acceptable qualifications for each EAS work category. Following the addition of new work categories to cover electric vehicle charging equipment, solar photovoltaic and electrical energy storage system installations, the Qualifications Guide now lists the available qualifications that fall under these categories.  Some of these qualifications have also achieved the ‘Electrician Plus’ kitemark and these are listed on the TESP website as being industry approved in terms of suitable entry requirements, content and assessment, helping to ensure that installations are carried out competently and are safe, high-quality and effective. The TESP website will also host any new qualifications that are approved in the meantime, before the next edition of the EAS and Qualifications Guide is published.  The Level 3 Certificate in Installing, Testing and Ensuring Compliance of Electrical Installations in Dwellings qualification issued by LCL Awards will no longer be acceptable for new applicants to a Certification or Registration Body from 1 January 2026.  Anyone who gains this qualification before January 2026 will be eligible to apply via the EAS Route 4 Older Qualifications. However, TESP is urging any new learners to carefully consider whether they can complete this qualification in time and, if it becomes a rush to try to register on the qualification, they be unfairly disadvantaged as there will be no EAS extension if it is not completed before the 1 January deadline. Other updates made to the EAS Qualifications Guide include updated guidance around insufficient qualifications and qualifications obtained outside the UK. The Qualifications Guide is available on the Electrical Careers website so employers, learners and training providers can access it and receive guidance where required.

Surge protection: A gap in your knowledge is a good thing

DEHN UK’s Robin Earl undertakes a comparison of type 1 surge protection devices and looks at the implications thereof. Not all surge protection devices are created equal – some are more equal than others! The whole purpose of fitting surge protection devices (SPDs) in an electrical installation is to limit the voltage that the sensitive equipment could see, to a level that will not damage the installed equipment. The SPD has a declared voltage protection level (Up) and this value must be below the withstand voltage (Uw) of the installed equipment or appliance. If Up is higher than Uw then damage can still occur, so the SPD needs to be changed or located closer to the end load as there is an additional inductive voltage that appears over cable lengths of 10m or more. 10m rule Referencing BS7671, in regulation 534.4.4.2, we find the 10m rule and this describes the effect of the surge device output voltage Up doubling over this distance, hence the requirements for additional SPDs to ‘knock’ the surge voltage down again to below the withstand level. This then brings up an interesting point about the energy coordination between the SPD and the end load, as it is not just about the voltage let through. There are two types of type 1 SPD, defined by the components within the device. There is the metal oxide varistor (MOV) and there is the spark gap. Let’s have a look at the make-up of each and how they function. First, MOVs are semiconductor devices made of zinc oxide with a ceramic-like structure. When the voltage across an MOV exceeds its rated threshold (clamping voltage), it starts conducting current, effectively diverting the surge current away from sensitive equipment and to the ground. They have a nonlinear voltage-current characteristic, meaning their resistance decreases as the voltage across them increases and are typically used in low to medium-energy surge situations, providing a quick response to transient surges. However, MOVs have limited capacity to handle large surge currents, especially when dealing with repeated or sustained surges. Over time, they may degrade due to the energy absorbed during surges, potentially requiring replacement. The alternative type 1 SPD relies on spark gap technology. These devices are simple, robust and reliable, consisting of two conductive electrodes separated by a small gap filled with a gas or air. When the voltage across the spark gap exceeds a certain threshold (sparkover voltage), the air or gas ionises, causing a spark to jump the gap and creating a low-resistance path for the surge current. Typically, spark gaps provide very fast response times and are capable of handling extremely high surge currents, including those generated by direct lightning strikes. Unlike MOVs, spark gaps have a wave breaking characteristic, meaning their resistance collapses as the voltage across them increases, and they present as a short circuit. Spark gaps are commonly used in high-energy surge situations where the surges are too large for MOVs to handle effectively. This is important as all equipment worth protecting already has an MOV inside as its inherent over voltage control measures. This appears in the standard BS EN 61000-4-5 to determine the voltage that equipment will withstand. As previously explained, all MOVs work in much the same way; they just get bigger to deal with higher energy and current values. The power supply for the screen on your PC has MOVs within it; they smooth over the peak of the surges that appear in the mains supply. All about coordination However, what is very difficult to predict is what happens when you install a MOV-based type 1 SPD with the small MOVs in the power supply. This becomes a coordination of energy issue, and this impacts all SPD installations. In BS7671 we find the following text in 534.4.4.5: ‘SPDs shall be selected and erected such as to provide coordination in operation by reference to the manufacturer’s data’. In, for example, the DEHNshield datasheet, a spark gap-based type 1 SPD in the 941 series family of products, we can see that the SPD offers type 1, type 2 and type 3 energy coordination up to 10m away. So, we could wire the display screen or any other end equipment into the SPD directly and be confident that the output of the DEHNshield will not be so high as to damage that equipment. Essentially, we have energy coordination. So, we declare this information and we also have type 1 SPDs for specific applications like EV charging points – the Emob SPDs – and those SPDs again have energy coordination to 10m but, in addition, less than half a joule of energy is let through. This is critical in those compact installations when short distances between the SPD and the equipment brings energy coordination issues. So, what of the type 1 MOV SPDs? Looking at the datasheets, we do not see either an energy coordination distance or a value of what energy is let through to the end equipment. It is not possible to determine a figure when coordinating the MOV of the SPD to the MOV in the end load. The smoothing action of the MOV does not limit the energy low enough to ensure protection within close cable distances in EV charging points, for example, or in switchgear that has measuring and metering equipment or monitoring devices. Graphic illustration In Fig 1 we see a blue line for the surge current entering the system going to the end equipment. The green line on the left-hand side shows the current through the type 1 MOV SPD, which has taken out the worst of the surge. The red line is the current that does get to the end load. Clearly this can be too much, and the end load can be damaged, especially if the cable distance is within that 10m as there is no energy coordination. Now to the spark gap type 1 SPD on the right-hand side. Again, we see the blue line showing the same surge current into the system and the green line is the current through the SPD; the difference is the red line that shows the current to the end load. This is a far lower current; in fact, so low that even equipment connected to the SPD directly will not see enough energy to damage it. The difference is that the spark gap acts like a binary switch – it is normally open circuit and then, in surge events, it’s a short for the surge current to earth. That small blip in the red line is the dwell time for the SPD turning on and that’s it. It is for this reason that DEHN does not produce MOV-based type 1 SPDs due to the inability to state that energy coordination is possible at all distances and that the number of joules that can be transmitted to the end loads could be way too high. Just to remove any doubt or perceived bias, the commentary above and the graphs are based on actual experiments conducted in a lab to compare the performance of the two types of type 1 SPDs. In both cases, the cable connections were very short and the lightning impulse value was 12.5kA. The outcomes were significantly different. In the MOV test, the varistor representing the end load was destroyed totally and in the spark gap test there was no damage at all to the varistor end load. In these tests, up to 99.4% of the impulse current is diverted to ground due to the action of the spark gap design. So, as previously mentioned, not all surge protection devices are created equal – some are more equal than others!

Compliant emergency lighting

In this article, Chris Anderson, Technical Manager at Ansell Lighting, provides an update on recent changes to emergency lighting legislation and looks at new products that will support easier monitoring and maintenance for customers. Keeping up with evolving regulations and the latest technological advancements is critical for everyone involved in designing, installing and maintaining emergency lighting systems. These systems play a pivotal role in safeguarding lives during power outages and emergencies, and are a core element of safety regulations in public buildings. When it comes to emergency lighting, there are a number of laws and standards that govern its design, installation and maintenance in the UK. These include The Regulatory Reform (Fire Safety) Order 2005, The Health and Safety at Work Act, Building Regulations, The EU Workplace Directive and Fire Safety Regulations. The most recent changes to regulations that have been made include updates to the British Standard BS EN 50172:2004; now known as BS EN 50172:2024. According to BS EN 50172:2024, which applies to emergency escape lighting illumination specification and system testing, emergency lighting systems now require an additional bi-annual test of emergency luminaires on top of pre-existing monthly and annual tests. This revision is to ensure that luminaires are undamaged and that their intended function is not impaired due to the presence of dirt, dust or visible material degradation. With this added testing obligation in mind, now, more than ever, contractors should be focused on specifying products which have automated, self-test functionality, to ease the time burden this additional requirement will have on building operators and facilities managers. As a manufacturer, Ansell Lighting often hears from such groups that ongoing maintenance and compliance checks take up a significant amount of their time, so implementing self-test systems can greatly streamline these processes, reducing labour intensity, any margin for human error, and adding value to the client’s maintenance and operational efficiency. Easy to install and operate, products with intelligent self-test lighting features make the testing process much quicker and easier for users. These products perform tests automatically on a selected date each month and year as required and in compliance with legal regulations. They feature a small LED button on each fitting which indicates regular function or signals a fault, leading to a quicker and more cost-effective testing and maintenance process. Emergency exit signs, emergency exit boxes, emergency downlights, emergency twin spots and emergency bulkheads are all available with this innovative technology. Taking this intelligent testing one step further, light monitoring dashboards are a brand new technology which further ease the process of emergency lighting testing and monitoring. Suitable for use alongside smart lighting systems, they monitor all emergency lighting assets in real time, providing instant alerts if any component fails. This constant vigilance ensures that building occupants are protected, and safety standards are consistently met, whether in a single office or across an entire portfolio of buildings. They also provide a convenient hub from which all lighting data and reports can be accessed and stored, meaning that the status of every emergency lighting device at any time, past or present, within a building or across multiple sites can be viewed easily in one place. In another change to existing regulations, the British Standard BS EN 1838:2013 has also been revised, recommending that Adaptive Emergency Escape Lighting Systems (AEELS) should now be used in all types of buildings. AEELS are highly intuitive, advanced lighting systems that help guide building occupants to safety. Using sensors and monitoring devices, they can detect changes in the environment, harnessing intelligent control technology to automatically modify factors such as escape route direction, the visibility of emergency signage and lighting levels on escape routes dependent on changing conditions. This adaptability makes them particularly effective in complex or high-occupancy buildings, ensuring safe evacuation under dynamic circumstances. Emergency lighting is far more than a box-ticking exercise - it’s a lifesaving measure. As regulations evolve, it is important that everyone involved in the emergency lighting process stays informed and adaptive to new technologies to ensure installations are not only compliant, but also effective. Electrical contractors play a pivotal role in ensuring all lighting systems meet compliance standards while delivering reliable, long-lasting performance. Embracing innovations and staying ahead of the curve will not only improve safety outcomes but also position contractors as trusted, forward-thinking professionals in the industry.
