There are many quirks in life that I find interesting, but since finding employment in trade publishing one that has become increasingly apparent is the esteem that other professions are held, in comparison to the core trades, especially when it comes to potential customers asking for preferential pricing or ‘mate’s rates’.
Indeed, the old adage that everyone should know a good electrician, plumber or builder springs to mind here, and even better if they happen to be a family member or a personal friend Not only is a skilled professional just a phone call away, but better still you can get a nice discount purely from your association
New research suggests that not only is this outdated attitude still prevalent, it’s on the rise, with trade workers being asked nine times a month on average by friends or family for free labour or advice.
Although the majority (rightly) would not do the job unless they were paid, research reveals workers give up over a week of their time on average every month, free of charge
Eager to please, a quarter (25%) offer ‘mate’s rates’ as they feel guilty not doing it and 68% say they feel pressure to, even though they don’t want to (23%) On average, those who do cheap work for friends and family believe they lose out on around £1,400 a year
As a result, workers are hit by two different losses – time AND money
However, 39% admit they make up excuses, such as being “too busy”, to get out of doing free work for friends Almost a quarter (22%) have pretended they have an emergency to deal with, while 1 in 5 (21%) fake illness to get out of doing jobs they will not be paid for.
In the case of self-employed trade business owners, they don’t get paid holidays, annual leave, sick pay, or receive industry perks. Instead, in a good number of cases, they have to graft for every penny to make ends meet and to afford themselves the time off work that so many
of us ‘employed’ individuals have the luxury of being able to simply book in on a calendar or spreadsheet
And why should trades professionals be expected to support friends and family who, in a lot of circumstances, may be in a better position as an employeee of a firm?
Of course, the electrical industry in particular, is one that has a generous spirit throughout its core and there will doubtless have been lots of occasions where many of you reading this column will have put your skills to good use as a favour for someone, or taken on the odd job at a discounted rate
That’s your right to do so, but it’s the weight of expectation that’s the killer Will it stop at just one job/favour, and will you be paid accordingly next time you’re called upon?
Of course, it shouldn’t have to come to this – especially if said individuals know you well enough to understand that you have a business to run, and appreciate that they are fortunate as it is, to be abl to call on a skilled professional who will likely fit them in at a moment’s notice.
Sometimes a bit of straight talking is what’s required, as difficult as that may be.
Educate them on the costs involved when you’re running a business and explain that you’re putting all your profit back into your company so that you can ensure you have a business that is profitable and a life that is representative of that If they won’t accept that explanation, it’s probably time to take a look at your friendship group!
After all, if you were asking the same of a family member or friend who works as a doctor, dentist, lawyer or architect, you can guess what the response will be!
Have a good month and enjoy the issue.

TESP provides EAS Qualifications
Guide update
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 1st January 2026
Other updates made to the EAS Qualifications Guide include updated guidance around insufficient qualifications and qualifications obtained outside the UK
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 1st January deadline

Landmark amendment to Payment Practices approved
Following consistent advocacy by ECA, the amendment to Reporting on Payment Practices and Performance Regulations has been approved, representing a long-awaited win for ECA Members and the wider construction industry.
This amendment will enhance transparency in retention procedures with qualifying businesses obligated to publicly disclose details on their payment practices From 1st March, when the changes come into effect, large businesses will be required to report the following metrics:
l the percentage ratio of the amount of retention that is withheld from the company by its clients, which the company holds back from its suppliers
l the percentage ratio of the amount of retention that the company withheld from the total value of payments made to suppliers as a proportion of the amount paid to suppliers during the reporting period
This overdue reform addresses a critical issue in the construction sector: late payments, which disproportionately affect small businesses with limited financial reserves These metrics will directly benefit small and medium enterprises by providing better information about a company’s retention payment practices This increased transparency is expected to incentivise large businesses to adopt fairer payment practices
Rob Driscoll, ECA Director of Legal & Business, said: “Both the Commons and the Lords approved another significant
milestone in the fight for fairer payment on behalf of ECA Members At first, making large firms report on their retentions may not seem much, but it will expose the size and nature of the problem of retentions abuse, allowing us to pave the way for an industry and government agreed solution
“We’ve been working towards these steps for a long time, which includes liaising with ECA’s equivalent in Australia and New Zealand for inspiration to motivate reform in the UK.”

ESPIRE TO BE BETTER WITH ESP ALARM RAnge
We discover more about how ESP is set to ignite the fire and CO alarm market with its latest launch.
Already an established and respected player in the UK fire protection and security industry, ESP is continually looking at ways to improve and develop its existing product offer
The result of its most significant new product development programme to date sees the company enter the fire and safety alarm market and introduce a new name to the sector, with the launch of Espire
Espire is a comprehensive range of high performance fire and CO alarm products that has at its core quality, reliability and innovation Sitting as a separate brand under ESP’s growing product portfolio, Espire will benefit from the expertise that the team at ESP has garnered from over more than 25 years’ operating in the fire protection and security sector
Safety a priority
With a product category that plays a crucial role in safety, it’s imperative that the products are of the highest quality, have undergone rigorous testing procedures and comply with all the relevant standards ESP has invested significantly to create a range of products to meet these exacting requirements.
The full Espire collection has been developed from scratch The project underwent a thorough design process,
involving extensive research, prototyping, and detailed refinement. To maintain strict quality control measures and product consistency, the factory is subject to rigorous internal audits and measures It utilises state-of-the-art testing and manufacturing equipment alongside a highly experienced team
Compliance and sustainability
The range will help installers meet the recommendations of BS5839-6: Code of Practice for the Design, Installation, Commissioning and Maintenance of Fire Detection and Fire Alarm Systems in Domestic Premises, and BS EN 50292: Electrical apparatus for the detection of carbon monoxide in domestic premises –Guide on the selection, installation, use and maintenance
All Espire products have undergone a meticulous design, development and manufacturing process at the dedicated factory As part of this, all alarms have been tested by third party test houses and certified by LPCB (Loss Prevention Certification Board) and TUV, to meet the relevant product standards – BS EN 14604 for smoke alarms: BS 5446-2 for heat alarms and BS EN 50291-1 for CO alarms.
Each alarm is tested a minimum of four times on the production line including the sensor, sounder, interface and functional
tests, concluding with a final assembly test. All products subsequently come with a five-year warranty.
ESP has taken a proactive stance on sustainability by integrating, where possible, eco-friendly materials and energy-efficient designs The company has used recyclable packaging material across the entire range, opting for eco-friendly, brown card packaging that is fully recyclable and 100% biodegradable

“PAST LESSONS CAN SHAPE THE FUTURE”
Mike Stark, SELECT President, looks at the reasons why public safety has been a recurring theme in the history of Edinburgh-based SELECT.
In order to look forward and plan efficiently, it is prudent to look back and consider how the voices of the past can inform and influence the direction of the future This strategy would seem particularly prudent as SELECT currently celebrates its 125th year empowering electricians and electrical businesses across Scotland.
As part of its celebrations, the association is preparing to publish an in-depth timeline which traces its roots back to the turn of the 20th century
As well as representing a mammoth task of research, this fascinating look back at our history uncovers a recurring theme that is still just as relevant – the ambition of the electrical industry in Scotland to keep its customers and wider society safe. Although much has changed along the way, there’s plenty we can learn from the past as modern electricians still face many of the issues raised by their forebears – not least a lack of skilled labour, late payments and unqualified/dangerous tradespeople
Our institution came into being when contactors in Glasgow, faced by the
encroachment of untrained competition, formed the Electrical Contractors’ Association of Scotland in November 1900 and in doing so became the world’s first body for the electrical sector
Expansion across the country
The association quickly flourished, attracting 250 member companies and expanding across Scotland as separate branches were established in the following years Annual subscription was two guineas; equivalent to £200 today
By 1917, it was facing for the first time an issue which is still at the forefront of our activities – the need for the registration of electrical businesses to ensure quality and the highest safety standards. As the timeline reveals, the association’s request for regulation was declined by the UK government, which said that “winning the war was its main concern”
Undeterred, it formed a Propaganda Committee in 1924 to make sure its voice was heard in the corridors of power and continued to raise its profile throughout the 1930s with activities such as discounting
electric lamps for collieries and supplying the lighting for the six-month Empire Exhibition in Glasgow in 1938
In 1939, as the clouds of war gathered once again, the association returned to Parliament to plead the issue of compulsory registration to keep the public safe from rogue operators – but once again, its appeal was dismissed on the grounds of lack of parliamentary time
More than 80 years later, after a name change and much economic and societal shift, the issue of regulation still shines as brightly as ever, and SELECT will continue to lead the campaign for protection of title as our timeline extends long after the 125th party is over
This year will be one of celebration for SELECT, but the association’s focus will remain where it always has been – on the interests of its members and the safety of their customers and wider society
COMMENT
How will mega trends, such as climate change, energy transition and efficiency, and digitalisation, impact the electrical industry in 2025? David Williams, Schneider Electric’s Vice President, Transactional Business for UK&I, predicts his top three trends.
TRENDS LIKE THESE
y g g p
The rapid evolution of technology has led to a growing skills shortage in the electrical industry, impacting productivity and growth And with an estimated 20% of the workforce in the UK (6 5 million people) set to be significantly under skilled for their jobs by 2030, the expertise of engineers will be crucial
We’ll see advances in technology making training more accessible to a wider range of people wanting to upskill in the face of increasing digitisation across the industry
AI, social media and QR-codes will all be used to make educational assets and courses available to those who may be less IT-savvy, delivering training in a way that best suits their needs
I also expect there will be more opportunities for people wanting to join the electrical industry through apprenticeship schemes and career change programmes to develop the new talent we need to recruit as the industry evolves and demand increases
p j
Customers recognise the need to modernise outdated electrical infrastructure to improve energy efficiency, reduce waste, and help them meet their sustainability goals
Budget constraints will make retrofits the preferred choice for many in the next 12 months For contractors it will be important to address customers’ urgent needs to deliver increased energy efficiency but also think about the longer-term benefits of the equipment selected and the potential return on investment over time
3. New regulations will make active safety more of a priority
UK wiring regulations are being updated to improve safety and energy efficiency
These updates include the Arc Fault Detection Devices (AFDDs) to prevent electrical hazards and changes to Part L, which focus on energy efficiency in buildings As a result, there's growing demand for smart, connected solutions that help monitor energy use, manage
y This will be specific to certain installations such as high-rise residential buildings, houses with multiple occupancy, purpose-built student accommodation, care homes, and facilities that house irreplaceable goods.
The emphasis on safety for high-occupancy and high-value buildings signals an industry shift towards adopting advanced fault detection solutions, likely impacting both new projects and retrofitting initiatives
Customers will be looking for increased reliability, resilience, and longevity so there will be increased opportunity to deliver a more preventative approach to fault detection. This will help customers to better anticipate what may go wrong and reduce downtime, limiting the impact on their business
SAFE ISOLATION: HIDDEN THREATS
Before I start, let me first clarify that I fully support the practice of safe isolation, actively promote its use, and advocate for continuous improvement in its application
This article contains my own thoughts and opinions, based on real-world experiences, and is designed to be thought-provoking and to create opportunities for further discussion around the subject area
Hidden risks
It’s well established that safe isolation is an essential practice in the electrical industry, designed to protect engineers and others from potential hazards
However, while safe isolation enhances safety in most situations, it presents its own unique challenges and risks during specific testing scenarios, such as live testing of Ze (earth loop impedance), PFC (prospective fault current), and PFCC (prospective fault current at consumer units), as well as when using locking-off kits
We’ve all experienced it – locking off a distribution board (DB) or consumer unit (CU), only to find the locking-off kit
swinging back and forth as you prepare to remove the cover This seemingly minor issue can, however, have significant safety implications
When the cover is removed, the conditions behind it are often unknown Shrouds may not be securely in place, terminations could be loose, or other faults may exist In these situations, a swinging lock-off device and padlock, especially on a three-phase (TPN) DB, can become hazardous
In the worst-case scenario, the lock-off kit could come into contact with one or more phases, creating a short circuit Similarly, the cover itself could become energised if it makes contact with a phase via the lock-off kit To mitigate these risks, extreme caution must be exercised when removing the cover with a lock-off device in place.
My advice in this scenario is to remove the cover first, then install the locking-off device to minimise the risk of contact with live parts
Safe isolation and testing Ze
When testing Ze or ZDB (distribution board impedance), it’s necessary to isolate the installation to eliminate parallel paths
Damion Evans, owner of Ex Forces Electrician, shares his thoughts on some of the hidden dangers that can be associated with safe isolation when carrying out live testing of Ze, PFC and PFCC.
“When the cover is removed, the conditions behind it are often unknown...”
and ensure accurate test results However, this isolation increases the risk of electric shock during the testing process, requiring engineers to take extra care. The presence of locking-off kits during testing can introduce additional risks Lock-off devices and padlocks can obstruct safe access to terminals on the incoming side of the main switch, increasing the likelihood of accidental short circuits
Conducting a risk assessment
It is crucial to assess the risks associated with using locking-off kits during live testing. If you determine that the locking-off device presents a greater danger during testing, it is reasonable to temporarily remove it You should then replace the lock-off device immediately after completing the tests When performing these tests, you are typically in direct control of the area, standing directly in front of the main
switch This makes it highly unlikely that someone would re-energise the installation without your knowledge In such scenarios, isolation combined with other control measures – such as barriers – can provide adequate safety
Industry guidance
Guidance Note 3 (GN3) includes an image of a lock-off device in use (pictured, right)
A
However, the accompanying text does not explicitly require a lock-off kit
It states: “With the main switch open or with all circuits isolated ”
Similarly, BS 7671 defines isolation as:
“A function intended to make dead for reasons of safety all or a discrete section of the electrical installation by separating the electrical installation, or section thereof, from every source of electrical energy ”
This definition highlights that isolation can be achieved without a lock-off kit in specific circumstances, provided the risks are managed appropriately
A logical approach to safety
If your safety equipment – such as a lock-off device – creates additional hazards during testing, it is safer to temporarily remove it You should, however, ensure the equipment is replaced immediately after completing the tests
Safety must always take precedence, and a logical, risk-based approach is key to preventing incidents By addressing these hidden dangers and carefully
assessing the risks, we can continue to use safe isolation effectively while adapting our practices to maintain safety during live testing
Let’s not forget, although safe isolation is a vitally important industry practice, it’s not always a one-size-fits-all solution!
THE DYNAMIC DUO
As the first housing association in England to attain the Zzeus Level 3 NVQ in Fire Alarm Systems, Paul Hadfield and Steve Heap from The Guinness Partnership share their insights on why the correct training is vital in ensuring the highest standards of fire safety.

Prioritising fire safety
The Guinness Partnership was founded over 130 years ago and is one of the largest affordable housing providers in England Guinness is committed to improving the lives of individuals by providing as many high-quality affordable homes as possible, and the housing services that residents most need It serves nearly 160,000 residents across the country, in nearly 70,000 homes
Having attained the Zzeus Level 3 NVQ in Fire Alarm Systems, Paul is keen to highlight the immediate benefits, stating: “Firstly, it’s great for us to promote that we have achieved one of the highest fire alarm qualifications on offer
“Secondly, it’s a real feather in our cap that we’re the first company in the social housing sector to achieve the NVQ, further demonstrating Guinness’
continued commitment to professional growth and safety.”
Enhancing skills and expertise through expert training
For Paul and Steve, achieving the NVQ is simply the beginning, rather than the end, of a longer journey
“It’s not just about the qualification It’s about setting a standard and proving that Guinness can lead the way in fire safety,” says Steve.
This is underpinned by an ongoing commitment to professional development within the team and Guinness as a company Indeed, Paul and Steve’s experiences highlight the dedication to continuous learning and staying ahead in a dynamic field
The company places significant importance on maintaining industry
relevant qualifications, with regular in-house training and CPD sessions a staple of its professional development strategy
Furthermore, Guinness’ Investors in People Gold accreditation reflects a focus on workforce development, with funding allocated for qualifications that enhance skills and instil confidence in clients.
The NVQ pathway
The latest landmark in Paul and Steve’s professional journey was the decision to pursue the Zzeus NVQ Level 3 Diploma in Fire Safety Systems, with both agreeing that it will help them to stay ahead of the curve and to be in a strong position to meet the requirements, if and when legislation and regulations are tightened further in the future
This NVQ builds upon the duo’s previous training, such as the modules they completed with various providers, including FSTA and Zzeus, while their decision to enrol was further influenced by their commitment to staying current with industry standards and remaining ahead of the curve.
Reflections on the Zzeus Level 3 NVQ
The journey to attaining an NVQ in fire safety is as much about practical experience as it is about theoretical knowledge
The NVQ process which the pair completed this year, involved collating evidence, including qualifications, job
examples, and video demonstrations of key tasks like fire alarm testing and safe isolation Steve and Paul found the process very straightforward, particularly using the online portal for uploading evidence
As Steve explains, a highlight of the process was the site visit from their assessor, Dr Tom Brookes (otherwise known to PE readers as ‘Dr Zzeus’): “It was really good to show him what we do in person after communicating lots originally via the portal and emails ”
Thoughts on the Zzeus four-day course in BS 5839-1
Paul and Steve both also attended a four-day course with Zzeus in mid-2024, which they found comprehensive and engaging with Paul describing it as “refreshing”, adding that it provided a strong foundation while complementing their existing knowledge
Their course was packed with interactive learning and practical exercises Days were well-structured, with a balanced mix of focused teaching, quick breaks, and engaging discussions
The emphasis wasn’t on rote learning but on sharing real-world experiences, particularly from the instructors, Buddy (Squires) and Tom, who brought a wealth of industry knowledge to the table
Steve remarked: “You're not just getting knowledge from books It's people talking and sharing their experiences That, for me, is a big part of learning ”
Paul agreed, highlighting the value of
smaller class sizes: “The setup was great
The class wasn't too big – just enough to ensure quality over quantity ”
He contrasted this with other training providers, where large class sizes can often dilute the personal experience and interaction.
Both achieved impressive scores, a testament to the effectiveness of the training structure
Compliance and confidence
Beyond personal achievement, Steve and Paul demonstrated the importance of training in the context of fire safety
“Post the Grenfell fire tragedy, there’s heightened focus on fire safety. Training ensures we deliver systems that keep residents safe,” Steve explains
By working for an organisation that is committed to professional development, they have the resources and support to pursue such qualifications, ensuring their work meets the highest standards
Their experience also demonstrates the value of ongoing learning, with Steve reflecting on the significance of choosing the NVQ pathway: "It’s not just about meeting today’s demands, but preparing for tomorrow’s challenges
“Staying ahead ensures we continue to deliver exceptional service to the Guinness Partnership "
Advice for aspiring professionals
For smaller companies or independent engineers, the time and financial commitment can be significant, but the rewards are undeniable
“It’s an investment in safety and credibility,” Paul points out
Steve adds: “Any training that increases our knowledge and confidence is worth pursuing ”
Their journey, from classroom training to on-site assessments, exemplifies how Zzeus Training empowers professionals to excel in fire safety.
For those considering an NVQ in fire safety, Steve and Paul’s story serves as both inspiration and a practical guide
The team at Hager explain why the brand’s Type B HP RCDs are essential for modern heat pump applications.
PRIME THE PUM
The electrical industry is experiencing rapid technological advancements and growing regulatory complexities, especially with the push towards renewable energy solutions such as air source heat pumps (ASHPs)
With the increasing adoption of these systems, ensuring safety and compliance in electrical installations has never been more critical. At the forefront of addressing these challenges is Hager’s innovative Type B HP RCD (RCCB), a device specifically designed to meet the unique demands of heat pump applications
The necessity of Type B RCDs in heat pump installations
Air source heat pumps operate differently from traditional electrical systems These devices often utilise inverter driven compressors to convert AC power into DC and back again, generating high frequency currents during the AC-DC switching process These currents can include smooth DC and high-frequency residual currents that exceed the capabilities of standard RCDs
Type B RCDs are uniquely suited to handle this complexity, as they detect and protect against AC, pulsating DC, and smooth DC residual currents. For heat pump installations, this capability is crucial Without appropriate protection, RCDs can become magnetised in the presence of DC components, compromising their functionality This phenomenon, known as RCD blinding, leaves the system unable to detect earth faults, significantly increasing the risk of electric shock
Hager’s Type B HP RCDs the standard Type B capabilities These devices are specifically engineered to function at frequencies greater than 20 kHz, ensuring a minimum tripping threshold of 150 mA for frequencies above 1 kHz
This precision is critical for addressing the unique safety challenges posed by modern heat pump installations

You ask: WHEN I’M TESTING RCDS, I REALLY LIKE THE CONVENIENCE OF AUTOMATIC TESTING BUT NOW THAT THE REQUIREMENTS HAVE CHANGED, I FIND IT ANNOYING TO HAVE TO GO THROUGH THE FULL SEQUENCE OF TESTS EVERY TIME WHEN I ONLY NEED SOME OF THEM. IS THERE ANYTHING THAT CAN BE DONE ABOUT THIS?
Megger says:
There is if you ’ re using the new Megger MFT-X1 multifunction installation tester This has an RCD test configurator that lets you choose which tests are included in the automatic sequence The tests available are 0 5 x I, 1 x I and 5 x I at 0º and 180º, and also a ramp test With the configurator, which is very easy to use, you can set up your own automatic test sequence. The 1 x I test always has to be included, but you can choose to include or omit any of the other tests to suit your own requirements Never again will you have to waste time while the instrument carries out tests you don’t want! By the way, this is only one of the ways the MFT-X1 saves you time and trouble For example, how about loop tests on ‘quiet’ circuits in as little as seven seconds?

Why do Emergency Lighting Batteries Last a Minimum of Three Hours?
ways f e al I’v
I’ve always been a fan of the underdog—the Spock to Captain Kirk or the Samwise to Frodo. Emergency lighting is the silent hero in building safety: always there but often overlooked until needed. When the power goes out, these luminaires kick in, providing essential illumination. But just as I wonder why Spock has pointy ears, you might ask why UK law requires batteries in emergency luminaires to last at least three hours.

Let’s start with the regs. The three-hour minimum aligns with UK fire safety standards governing emergency lighting, such as BS 52661. This ensures that even in large or complex buildings, all occupants can evacuate safely. In high-rise structures or facilities with vulnerable individuals—such as hospitals or care homes— evacuations take longer, and three hours provide a necessary buffer.

But it’s not just about getting people out. Emergency lighting supports Emergency Services, providing reliable illumination to navigate, rescue, and manage emergencies effectively. Whether extinguishing fires or aiding trapped individuals, the three-hour minimum ensures they can operate without the hazard of complete darkness. Not to mention, power outages may extend beyond evacuations. Occupants may need to shelter in place, requiring continued lighting for reassurance and visibility.

So, why not make batteries last longer? While possible, it would increase battery size, maintenance demands, and expense—without significant added safety benefits for typical scenarios. The three-hour rule reflects a careful balance of practicality, safety, and cost. I like to think that’s the kind of logical thinking Spock would get behind.

When considering the electrical design for a proper ty, whether it is a new build or a retrofit installation, the location of the wiring accessories and equipment must be considered in relation to Building Regulations along with BS 7671
The placement of the downlight and cable within a ceiling must take into consideration the location of any structural joists and beams. Under Approved Document A (Structure) it is not permissible to remove par ts of the joists, as shown in these pictures, as this would exceed the maximum notch depth
This type of installation has been carried out without correct planning to ensure that the downlights are positioned in between the joists Clashes with joists should not be an unexpected occurrence if a sur vey of the ceiling void has been carried out
Whenever such a clash happens the installer should re -mark the lighting layout to miss the joists, not just blindly carr y on with the installation Just because it can be made to fit does not mean it will
comply with Building Regulations and BS 7671
Apar t from the highlighted structural issues, there is an increased risk of the spread of fire with contact between the downlight and the timber sur faces.
During periodic inspection and testing, this downlight installation was discovered when a sample inspection was being carried out This would now require fur ther investigation and an increased sample size as there will almost cer tainly be similar installations of downlights
Therefore, the classification code would be a C2, Potentially dangerous, urgent remedial action required due to the risk of fire and lack of compliance with Building Regulations

Click Scolmore looks at considerations to bear in mind for the selection and erection of electrical accessories in those locations that are subject to mechanical impact.
MAXIMUM IMPACT
Asuitable for the location in which it is to be installed (132 5 1), and installed in accordance with the manufacturer’s instructions (134 1 1) and erected such that it is not compromised (134 1 2)
IK codes
BS EN 62262: 2002+A1:2021 Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK code), is a standard which ‘ refers to the classification of the degrees of protection provided by enclosures against external mechanical impacts ’
Table 1 in this standard details the codes for the impact energy (in joules) that the equipment is capable of withstanding
Whilst Appendix 5 of BS 7671 doesn’t reference IK codes (it references ‘low’, ‘medium’ and ‘high’ severity of impact), there are a number of regulations within the standard which make specific
references to BS EN 62262, including for example, Regulation 708 512 2 1 3, 709 512 2 1 4, and 712 512
Design considerations
When designing an installation, it’s important that the designer gives careful thought to the nature of the activity and conditions likely to be found in the installation
Where there is a likelihood of a risk of impact designers, amongst other things, should select products capable of withstanding such impact Whilst there are only a few regulations detailing specific parts of an installation requiring a minimum energy withstand (IK code), there is a more general need to ensure that any installed equipment is suitable.
Installation
There is a duty on installers to ensure that they install any equipment in accordance with the guidance issued by the manufacturers of a product
More than this however, they should also ensure that their activities do not compromise the product itself, which can be caused by excessive force, incorrect location, poor fixing and the like
Examples
Consider the following cases:
a) A campsite has supplies available for various tent plots Regulation 708 512 2 1 3 is very clear, and because
of the increased risks associated with persons being in contact with Earth, installed equipment must have a minimum resistance to impact of IK08 (5 J)
b) A small industrial unit has a series of wall-mounted, surface wired accessories. In this instance there is no minimum declared IK value, however the general principles apply; that is to take account of the environmental conditions which apply As such, a designer would likely select metallic outlets
Conclusion
It is important that both designers and installers take due account of the likelihood of impact when selecting and installing suitable products for those installations which have a harsher environment Additionally, certain special locations detail specific minimum impact requirements

THE EVOLUTION OF EARTH FAULT LOOP IMPEDANCE TESTS
Most technical support questions received by manufacturers of test and measuring instruments generally concern issues related to Earth Loop Impedance test results
More specifically, the variations in readings obtained with successive measurements,
comparisons between different test instruments, or readings that are an issue, such as just outside of the permitted minimum value for a particular installation
Why is loop testing important?
For a protective device in an electrical installation to operate within the maximum permitted time detailed on Table 41 1 of
Julian Grant, General Manager of Chauvin Arnoux UK,
recounts how loop tests have evolved over the last 40 years and explains the inherent measurement variability that has occurred along the way.
BS 7671, the earth fault loop impedance (Zs) for the circuit must not exceed the maximum earth fault loop impedance values for the protective device given in Tables 41 2 to 41 4
The earth fault loop path typically consists of the external impedance (Ze) and the resistance of the phase and protective conductors (R1 + R2) If the total
This is an issue which has been made worse over the years as loop testers have had to deal with testing on RCD or RCBO protected circuits without tripping them, and on installations with more electrical noise and harmonic currents than ever before
Back in the day 35 years ago, a loop tester would basically perform a high current test by applying a 10 Ω load to the supply being tested and then measure the voltage drop across it
It could then calculate the resistance of the loop and display it These tests were generally performed for two half-cycles of the mains supply, and with a test current of around 23 A, loop testers were able to produce fairly accurate results.
Since then, installation equipment and products have evolved, and loop testers today are very different instruments
Instead of high test-currents, the introduction of RCDs and a desire to keep products small, lightweight and able to perform large numbers of tests without going into thermal overload, pushed manufacturers to utilise test currents
below 15 mA and/or test durations that are so fast the RCD does not have time to react.
Even the high current loop tests in most products today only operate at a few amps, rather than the 23 A used in the past, due to the need to reduce circuit size, costs and heat dissipation. This was something that became even more necessary with the need to fit the loop testing circuit into a multifunction tester as the popularity of MFTs increased
Using smaller test currents makes it much more difficult to obtain reliable measurements and increases the susceptibility of those measurements to the effects of electrical noise and harmonics, all of which reduces the accuracy of the results.
This required manufactures to develop ever more sophisticated measurement techniques, resulting in different test methodologies from different manufacturers, leading to slightly different measurement results
The level of potential variability in a loop test is published in the specifications of the test instrument’s user guide, however, such things often go unread and unfortunately for many there is a natural inclination to take what is on the display as the definitive test result
Specifications and their effects
Some typical loop test specifications and the variability of result they can give on a 0 35 Ω loop are shown in the table (below)
The products are not identified, but they are all popular brand MFTs currently available in the UK and these figures are taken directly from the manufacturer’s published specifications.
Apart from the accuracy % of reading, the number of digits represents variability of the least significant digit on the display
Accordingly, ±5 digits on a 0 01 Ω resolution range means the reading can be out by an additional ±0 05 Ω And a loop with an impedance of 0 35 Ω, measured on a product with 0.01 Ω resolution and an accuracy of ±5% ±5 digits, could be displayed anywhere between 0 28 Ω and 0 42 Ω which equates to ±20%
Similarly, a 0 10 Ω loop impedance measured on the same product could be displayed as 0 05 Ω or 0 15 Ω, an error of ±50%
Avoid all doubt
To avoid any doubt, always try to use an instrument where the expected loop test values for the installation under test are well within the range and limits of the instrument
Some MFTs available today, including the Chauvin Arnoux CA6117, incorporate a 0 001 Ω resolution loop test range which would be a benefit
If your product measurement accuracy is inadequate for the job in hand, other methods of assessing the circuit’s characteristics might be more appropriate, such as using a calculated or enquired value for Ze
Awareness of the precise measurement capability of your equipment, and the need to understand if the variability in readings mean the loop test range is suitable or not for the job in hand, are essential to ensure accurate results. If you don’t know already, look in the specifications section of the user guide or contact the manufacturer

An SPD is a protective device that is installed to safeguard electrical systems, including the consumer unit, wiring and associated components, from power surges, which are referred to as transient overvoltages
It also provides protection for sensitive electronic devices connected to the system, such as computers, televisions, washing machines, as well as safety circuits like fire detection systems and emergency lighting Electronics with delicate circuitry are particularly susceptible to damage caused by these transient overvoltages.
What are transient overvoltages?
Transient overvoltages are brief electrical surges that happen when energy, previously stored or introduced by other methods, is suddenly discharged These overvoltages can arise from both natural events (lightning strikes) and human activities.
Man-made transients are generated by the switching of motors, transformers and certain types of lighting In the past, this was not a common issue in residential installations
However, with the rise of modern technologies such as electric vehicle chargers, air and ground-source heat pumps and speed-controlled washing machines, the likelihood of transients occurring in domestic installations has significantly increased
Natural transient overvoltages are typically caused by indirect lightning strikes, often resulting from a direct strike on a nearby overhead power or telephone line As a result, the transient overvoltage can travel along the
overhead lines and the distributor’s network, potentially leading to severe damage to the electrical installation and equipment connected to it
What are the different types of SPDs? SPDs provide different functions and are classified as Type 1, Type 2 and Type 3 devices
Fig 1: Example of a Type 1 SPD
Fig 2: Example of a Type 2 SPD
Surge Protective Devices (SPDs) safeguard electrical components from power surges
Type 1
Type 1 SPDs should be installed at the origin of the electrical installation located in or adjacent to the main distribution board
These devices deal with direct lightning strikes and are also used where structures have Lightning Protection Systems (LPS)
Type 1 SPDs, as shown in Fig 1, are used at the origin of an installation and in lines to or from structures originating beyond the area of protection afforded by the fitted LPS Also known as equipotential bonding SPDs, Type 1 SPDs prevent dangerous sparking, averting fire or shock risks. It is important to note that LPS with only Type 1 SPDs fitted won’t protect sensitive equipment against failure However, Type 1/2 combined units overcome this
Type 2
Type 2 SPDs may be installed if the structure does not have an LPS fitted or does not require protection against direct lightning, see Fig 2
Type 2 SPDs are used for indirect lightning effects and are known as surge arrestors Where required, these may be installed at the origin, as well as at additional sub-distribution boards This allows sensitive equipment within the
installation to be adequately protected. Type 2 SPDs shall be coordinated with any Type 1 SPDs installed at origin
Type 3
Type 3 SPDs shall be installed close to any sensitive equipment that requires protection, such as data/server racks and cabinets, see Fig 3. Type 3 SPDs shall be coordinated with Type 1 and/or Type 2 SPDs installed at the origin
Regulation 443 4 1 requires that protection against transient overvoltages shall be provided where the consequence caused by overvoltage could result in:
l serious injury to, or loss of human life or
l significant financial loss or data loss
For all other cases, SPDs shall be fitted to protect against transient overvoltages unless the installation owner declines such protection and wishes to accept the risk of damage to both wiring and equipment as being tolerable
Where the owner has declined SPD protection, it is important to record your recommendations for the protection against overvoltage This can be done by
using the NAPIT SPD Risk Declaration form, see Fig 4
Conclusion
The decision to install SPDs ultimately lies with the customer, but they should be provided with clear information to make an informed choice about whether to install SPDs or not This decision should consider safety risk factors and include a cost comparison, taking into account the cost of the SPDs.
This cost should be weighed against the value of the electrical installation and the equipment connected to it, such as computers, TVs and essential devices like smoke detectors and boiler controls
“The decision to install SPDs ultimately lies with the customer, but they should be provided with clear information to make an informed choice about whether to install SPDs or not.”

Dr. Zzeus
IN THIS REGULAR COLUMN, DR. TOM BROOKES, MD AT ZZEUS TRAINING AND CHAIRMAN OF THE FSA, ANSWERS YOUR QUESTIONS RELATED TO FIRE SAFETY. IN THIS MONTH’S EDITION HE PROVIDES ADVICE TO THOSE WHO MAY BE EXPECTING A VISIT FROM A BAFE AUDITOR AT SOME POINT IN THE FUTURE.
I have recently signed up for the BAFE SP203 Scheme for fire alarm maintenance. What can I expect from the auditor?
Firstly, do not panic about the assessment; most auditors are not coming to try to trip you up or crucify you. Their visit is to document what you do and check you meet the BS 5839-1 standard of work and comply with the BAFE SP203-1 scheme
Hopefully, by now, you have studied the BAFE scheme document (freely available from BAFE) and are conversant with BS 5839-1:2017 (2025 version due by the end of April)
Section 6 of the standard covers maintenance, however you also need good knowledge of the rest of the standard For example, if you’re on a maintenance visit, how would you know if the system category is an L2 if you don’t have the required design knowledge?
Here’s a few pointers to help you prepare for the process:
1. Before the audit
Prepare yourself ! The auditor will let you know what items they need to see, including:
l Maintenance procedures and schedules
l Records of recent maintenance work
l Evidence of staff training and qualifications
Make sure your paperwork is complete, up-to-date, and easy to access.
2. What happens during the audit?
The auditor will look at several key areas to check that you’re doing everything properly These include:
a) Maintenance processes
l Routine checks: They’ll check that you’re following the proper procedures for regular maintenance, like inspecting, testing, and cleaning fire alarm systems.
l Fixing problems: They’ll want to see how you handle faults or repairs, including how quickly you respond to urgent issues
b) Recent work
The auditor will review a sample of your maintenance jobs, including:
l Maintenance reports: Do your records show what you checked, what you found, and what you fixed?
l Compliance: Are your checks in line with the rules, such as those in BS 5839-1?
c) Tools and equipment
They’ll check that your tools and testing equipment:
l Are suitable for the job
l Have been calibrated and are in good working order
d) Your staff
They’ll assess if your team members are qualified and trained for their roles
Expect them to ask for proof of training, qualifications, or any updates to their skills.
e) Reports and communication
The auditor will ensure you give clients clear, professional reports after maintenance visits They’ll also check how you handle problems, recommend fixes, or suggest system upgrades
3. Checking your records
The auditor will look at how you keep track of your work:
l Schedules: Are you maintaining systems at the correct intervals (e g , every six months)?
l Client logbooks: Are these appropriately updated during visits?
l Faults/repairs: Are problems logged and fixed promptly, with clear records?
4 KEY THINGS TO FOCUS ON
1. Stick to the rules in BS 5839-1 for maintenance
2. Keep detailed and accurate records of all work.
3. Ensure your team is adequately trained and has the right tools
4 Communicate clearly with your clients, especially about problems or recommendations.
l Certificates: Are you providing proper paperwork to clients, like maintenance certificates?
4. Quality management
The auditor will check your processes for planning maintenance, dealing with complaints, and ensuring everything runs smoothly They’ll also want to see how you improve over time, like learning from mistakes or updating your procedures.
5 Site visits
The auditor will want to see a maintenance visit or review how you recently handled one They’ll examine how well your team follows procedures and interacts with the client
6. Feedback after the audit
l What’s good: The auditor will tell you what you’re doing well.
l What needs fixing: They’ll point out any problems, which might be:
l Minor: Small issues you need to address but don’t stop you from passing
l Major: Serious issues that need fixing quickly to keep your certification
7. Once the audit is complete If you meet all the requirements, you’ll either get or keep your BAFE SP203-1 certification for maintenance If there are issues, you’ll need to fix them and show the auditor evidence of the changes.
Top tip: If you are not happy with something the auditor says, or you think they are wrong, ask them to show you in BS 5839-1 and/or in the BAFE scheme document; no one is infallible It is very easy for someone (the auditor, you, or I) to miss something in the heat of the moment on a busy job And remember variations, if you cannot fully adhere to the standard

I’ve heard industr y apprenticeships now include ‘green’ skills.
What exactly will apprentices be learning?
To reflect the fact that much low carbon technology installation needs the core skills of an electrician, both the Installation & Maintenance Electrician and the Domestic Electrician apprenticeships now feature elements of low carbon learning
This means your recent, or next, apprentice will be learning about this in college, and it will form part of their End Point Assessment
This type of learning provides a great foundation from which they can move on to further upskilling, to gain qualifications in relevant low carbon technologies once they complete their apprenticeship
During the apprenticeship, they’ll develop an understanding of technologies such as electric vehicle charging equipment (EVCE), solar photovoltaic (PV) panels and electric energy storage Domestic Electrician apprentices will also learn about heat pumps and micro wind turbines for residential dwellings
During their End Point Assessment, to assure occupational competence, they’ll encounter aspects of these new technology areas alongside their wider electrical installation evaluation, to test what they’ve learnt during their apprenticeship
If your business doesn’t currently install these technologies, you can still access the apprenticeship and benefit from an introduction to these areas
For the Installation & Maintenance Electrician apprenticeship, the new updates are relevant to those who were registered after September 2023. Apprentices who started before this will be eligible to undertake upskilling qualifications in solar PV, EVCE and electric energy storage following apprenticeship completion
It’s worth checking out TESP’s Electrician Plus campaign for the approved qualifications, aligned to the forthcoming new work categories in the Electrotechnical Assessment Specification
With apprentices building their low carbon skills, it’s a stepping stone to full competence and taking advantage of future business opportunities in these growing technologies

HAPPY CHUMP DAY
Having launched his brand new innovation to much fan-fare at the end of January, we put the questions to Kieran Pye, the inventor of CHUMPFix, to find out more about the product and the benefits it can offer to electrical professionals.
QHow easy is it to fit the CHUMPFix and why is it faster than usual methods?
It’s much easier than plugs and screws –you simply drive the screws through the plasterboard and into the CHUMPFix As there’s no need to drill or install plugs, every time you use the CHUMPFix you’ll essentially be saving time It works perfectly with lathe and plaster but it may be the case that you need to use longer screws as the plaster in these walls can be very thick
QWhere can CHUMPFix be used?
CHUMPFix can be used to fix most surface-mounted fittings, such as pendants, smoke alarms, chandeliers, ceiling light fittings, wall light fittings, pull cord switches, surface-mounted sockets (both metal and plastic), fire call points, surface-mounted switches, as well as many others The unit can also be used to complete plasterboard repairs
A common application that we’re finding from the product is electricians using it to change a pendant to a decorative light fitting (in a new build
home, for example) Customers have commented at how shocked they are by the speed of the work and cleanliness involved, with next to no dust This offers a massive time saving on both the work and the making good
As the product gains traction, we’re having new applications presented to us all the time, including securing a light through a Victorian ceiling rose, attaching bulkhead lights to ceiling tiles, fitting
radiators and securing a smoke alarm over a 75 mm hole in the ceiling.
QHow tough is the CHUMPFix?
The CHUMPFix is designed to hold a whole array of fittings to plasterboard walls and ceilings The handle is designed to be strong so it can withstand multiple bends and will not pull though the CHUMPFix during installation
QHow many CHUMPFixs are contained in a packet and what colours are available?
There are five CHUMPFixs in each packet The product is currently only available in green
QWhat size screws are best for use in CHUMPFix and how many screws do you get?
We supply 4 mm screws to provide the best balance between installation and strength of fixing There are ten screws in each pack of CHUMPFix which will allow for two screws for each CHUMPFix
QWhat material is CHUMPFix made of ?
CHUMPFix is made of nylon as this is tougher than the usual polypropylene that most wall fixings, including yellow, red and brown plugs, are made from. This makes the fixing stronger while keeping the CHUMPFix thin and easy to use
QCan
CHUMPFix be used more than once?
Yes There are many holes in the CHUMPFix and each hole should only be used once To hold the plate for a second use the second square hole can be used with a piece of wire, or the handle can be pushed out of the hole during first use
QIs
CHUMPFix recyclable as a product, and is the packaging also recyclable?
CHUMPFix is made out of nylon, which is a tough plastic that can be recycled at most household waste facilities It should not be placed in domestic recycling collection bins We’ve made the packaging primarily out of cardboard, which is easily recyclable
QWhat
plans do you have to raise awareness further this year?
We’ve already booked into the ELEX trade show at Alexandra Palace later this month (stand E202) and we’ll be announcing
POSITIVE FEEDBACK FROM ELECTRICIANS
The initial response to the launch of CHUMPFix has been overwhelmingly positive from electricians:
“I needed that last week, where do I get them from?”
“What a brilliant idea!”
“Love the product – this has the potential to be a game-changer”
“Looks like a great solution to a common problem I’d definitely like a few in my toolbox”
“I need some of these!”
“I could have used that for a radiator I’ve just fitted I made a mess of the wall when fitting it, which I would have avoided with this product” (from a plumber)
further events in the near future
QWhere
can electricians purchase CHUMPFix from?
We’ve already secured some distribution through electrical wholesaler stockists, so make sure you ask your local wholesaler about the product We’ll also have more updates and stockists to share over the next few months
If you can’t access the product through your wholesaler, it can be purchased through our online shop –https://chumptools.com/shop

SEEK COMPENSATION
Paul Foulkes, UK Country Manager at Theben, explains why you and your customers can say goodbye to LED flicker and afterglow with the use of a handy new device.
Have you found yourself navigating the nuances of LED technology? While LEDs bring incredible energy efficiency and longevity, they also present unique challenges, especially when paired with dimmers From flickering to persistent afterglow, these issues can leave even the most seasoned professionals scratching their heads.
Enter Theben’s Compensation Module LED, the unsung hero that solves these common LED lighting headaches
Designed to complement dimmer systems such as the Theben DIMAX series, this compact yet powerful device tackles one of the most frustrating problems electricians face: LEDs that refuse to fully turn off or flicker unexpectedly due to residual currents.
The problem: Residual power and its overall effects
The transition to LED lighting has revolutionised energy consumption, but it hasn’t been without its quirks Unlike traditional incandescent bulbs, LEDs require only a small amount of power to emit light This sensitivity means that even
tiny residual currents in a circuit can cause LEDs to glow faintly or flicker when they should be off
For electricians, these complaints can become a frequent call-back issue, impacting customer satisfaction and costing valuable time
The Theben Compensation Module LED is designed to eliminate this frustration. Connected in parallel to the consumer, the module neutralises residual currents, ensuring LEDs remain off when they should be, and shine consistently when they’re on
Case study: Pancho Electrical
When Adam Pancho of Pancho Electrical faced flickering issues with a high-spec installation, we sent him the Compensation Module, knowing it would be the answer to his woes.
Adam explains: “We installed 5 x 35 mm GU10 LED lamps (3 W, 240 V, 2700 K, CRI 96+) on a dimmable circuit Despite meeting the specifications, the lights exhibited flickering and wouldn’t fully turn off
“Once we fitted Theben’s Compensation Module, the issue was resolved instantly It’s a small addition, but
it made a big difference.”
This is a common scenario Dimmable LEDs are often sensitive to fluctuations in the circuit, particularly when only a few lamps are connected By stabilising the current, Theben’s Compensation Module ensures a flawless performance, transforming a tricky situation into a seamless solution
A must-have in every electrician’s toolkit
With LEDs becoming the lighting standard, electricians need tools that keep up with evolving technology The Theben Compensation Module LED is a small investment that delivers big returns –solving frustrating issues, enhancing the client experience, and protecting your reputation as a trusted professional
Whether you’re installing LEDs in a residential setting or troubleshooting an existing circuit, don’t let flickering or afterglow dim your client’s opinion of your work

TRUE COLOURS
Mark Paul, Global Director of Sales at IRISS, suppliers of the Safe-Connect range of thermochromic indicators, looks at why the use of colour change technology can help to keep electrical systems and operatives safe and sound.
Picture this: you’ve just completed an inspection at a bustling site
Everything appears to be in good working order But beneath the surface, trouble could be brewing – a cable running hotter than it should, a terminal on the verge of failure, or a connection slowly degrading under stress. These overtemperature risks are invisible to the naked eye, lying dormant until they erupt into costly failures, unexpected downtime, or even dangerous accidents
For electricians, this scenario is all too familiar But what if there were a simple way to make these invisible threats impossible to miss?
That’s precisely what thermochromic overtemperature indicators offer. These innovative devices – available as clips, labels, and wraps – are applied directly to electrical equipment such as cables, terminals, and connections
When the temperature exceeds a critical threshold, the material undergoes a permanent colour change – in the case of Thermo Clips, shifting from purple to
pink This stark visual transformation provides an immediate and unmistakable warning of overheating
Even after the equipment cools, the colour remains permanently altered, serving as a lasting record of the event No advanced tools or technical training are needed; a quick glance is all it takes to pinpoint the problem area.
How does it work?
The magic of thermochromic indicators lies in their unique chemical composition
The molecular structure of the thermochromic material alters when it reaches a specific temperature threshold, which in turn changes the wavelengths of light it absorbs and reflects. This results in a vivid and permanent colour shift, making the problem areas stand out immediately
Unlike digital monitoring systems, thermochromic indicators require no external power source, wiring, or complex setup They operate passively, relying solely on temperature changes to trigger their colour shift This makes them incredibly reliable and easy to install
Whether you’re working with highvoltage switchgear or low-voltage distribution boards, these indicators can be deployed in seconds, providing continuous monitoring without the need for periodic recalibration or maintenance
Filling the gaps in routine inspections
While infrared (IR) thermography and other diagnostic tools remain essential for
electrical system inspections, their effectiveness is inherently limited by their periodic nature
IR inspections offer a valuable snapshot of an asset’s condition but only capture data at the moment of the inspection Between these scheduled checks, transient or intermittent overtemperature events often go unnoticed, leaving systems vulnerable to undetected risks.
Thermochromic indicators bridge this gap by providing round-the-clock monitoring Their passive, always-on nature means that they’re constantly
“When the temperature exceeds a critical threshold, the material undergoes a permanent colour change...”
watching for temperature anomalies, ready to alert you the moment a threshold is breached This complements traditional inspection methods, adding an additional layer of safety and reliability to your maintenance routine
Many electrical system applications
Thermochromic overtemperature indicators can be applied to virtually any electrical system component:
Cables and connectors
These are often the first points of failure in an overtemperature event, especially in high-current applications Thermo Clips and Thermo Wraps provide a simple way to monitor these critical areas.
Transformers and motors
Continuous operation under heavy loads can lead to dangerous overheating Thermochromic labels or Thermo Paint applied to these components offer a clear, visual warning before damage occurs
Control panels and enclosures
In busy industrial environments, overheating within control panels can lead to costly malfunctions External thermochromic indicators make it easy for operators to identify any hotspots without making physical contact
Busbars and terminals
These critical junction points are prone to thermal stress, especially in ageing systems. Thermochromic indicators applied here provide early warnings, giving you plenty of time to address the issue and reduce the risk of failure or fire
Empowering everyone on-site
One of the standout features of thermochromic indicators is their accessibility Unlike diagnostic tools like IR and ultrasound, which require specialised
training to operate and interpret the results, thermochromic indicators are simple to understand
A shift in colour is a universal warning sign, easily recognisable by any team member, no matter how experienced. This simplification of overtemperature monitoring means more eyes on potential issues and faster responses to emerging problems
By turning routine walk-throughs into effective monitoring activities, thermochromic indicators foster a culture of proactive maintenance Operators can spot potential problems during their daily rounds, prompting immediate investigation and preventing minor issues from escalating into major failures.
Safety, reliability and sustainability?
In addition to improving safety and reliability, thermochromic indicators align perfectly with modern sustainability goals Their passive operation means they consume no power, contributing to reduced energy usage across the facility They detect overtemperature events from loose connections, reducing energy wastage. Moreover, their durability ensures they remain effective for years, minimising waste and the need for replacements
By preventing equipment failures and unplanned downtime, thermochromic indicators also reduce the environmental and financial costs associated with emergency repairs and extended outages In a world increasingly focused on sustainable practices, electricians are embracing the fact that these indicators provide a practical, low-impact solution for enhancing industrial safety and efficiency
A game-changer
for electricians
For electricians, thermochromic overtemperature indicators represent a eap forward in electrical system maintenance They’re simple, effective, and affordable, offering a practical way to detect hidden risks before they escalate.
Whether you’re responsible for maintaining critical infrastructure or managing the day-to-day operations of an industrial site, these indicators empower you to stay ahead of potential failures with just your eyes
Think of them as an early warning system that never sleeps By making
overtemperature risks visible and impossible to ignore, thermochromic indicators help you improve safety, reduce downtime, and enhance the reliability of your electrical systems
In an industry where time is money and safety is paramount, this technology is poised to become an indispensable part of every electrician’s toolkit

complement or contrast with surrounding materials, depending on your preference
ROBUS customised the ZIIGNA luminaires for the Visitor Centre by selecting the following features:
Style: Suspended fittings were chosen because of the sloped ceiling and the overall function of the area called for uniform light
Size: A variety of custom-length modules were linked to create abstract angles, from 1 2 m - 2 0 m
Lumens: A variety of lumen outputs were used
Lighting direction: Down only
Extrusion colour: All black – it’s their brand colour after all!
Colour temperature: 4000K neutral white.
Dimming: No dimming required Emergency: No emergency required as they also installed AVIOR emergency downlights
Sensor: No sensors required
Whether the goal is to create a soft, ambient glow or vibrant, task-oriented lighting, ZIIGNA’s multiple-lumen packages and dimming options provide precise control over intensity This ensures that the right ambience is achieved for the different areas and activities of the Visitor Centre, all while maintaining visual comfort and reducing glare through its wide panel design.
Personalise any space
The Visitor Centre serves as an ideal backdrop for demonstrating ZIIGNA's ability to elevate a space’s aesthetic and functionality By empowering lighting designers to configure ZIIGNA in many
unique ways, the possibilities for personalisation are endless The beauty of ZIIGNA is that its technical adaptability ensures your lighting is always in harmony with the space For ROBUS, ZIIGNA is a fantastic way to guide the flow of the visitor experience

Luceco’s lighting provides food for thought
Luceco was recently asked to provide a comprehensive lighting solution at the new premises of Newberry International Produce in Hazel Park, Ledbury, to completely redevelop the space with the help of Adi Group
The new state of the art facility boasts full end-to-end automation to ensure flexibility and efficiency, providing specialist frozen goods including packaged fruit and smoothie mixes to suppliers
Sustainability was a key factor throughout the redesign process, including lighting design and installation
Working with Adi Group, Luceco created a sustainable LED lighting solution that included its Contour luminaires,
Platinum pendants and Darklights, and Ceres high bays. The lighting installation was then carried out by Adi Group
Lighting was required in various areas of the building, including office and circulation spaces, warehouses, and storage rooms. In the office spaces, Luceco’s Contour luminaires were used to create attractively lit environments whilst offering occupant friendly lighting
The Contour lighting range consists of connectable modules that can be surface mounted, suspended or recessed, forming highly effective, contemporary, decorative illumination
Platinum Pendants and Darklights were used to accompany the suspended Contour luminaires, offering a recessed
high performance low glare downlight with unique swing tab design that allows for quick and easy installation
In the warehouse and storage circulation areas, Luceco chose to use its Ceres high bays and Climate Extra IP65 linear luminaires. Ceres high bays are surface or suspension mounted high level luminaires, with an IK10 rating and over 100,000 hours of operational life, making it the ideal lighting solution for industrial and warehousing applications

ELECTRORAD
Accorto Intelligent Radiators
The Accorto by Electrorad is not only an exceptionally intelligent aluminium radiator, its heating control is designed for student accommodation, hotels and properties where landlords or property managers may want to set limits on energy usage. This ability to manage costs and avoid excessive heating caused by over-zealous users is a game-changer. The Accorto has three clever functions which will help control the radiators:
1. Constant set back – this enables the radiators to be set, locked and, more importantly, unlocked by the App alone The property manager can also opt to put the radiator into a constant setback and lock it, which then allows the “one button boost” function to be active, providing a boost of 23°C for 45 mins before returning to setback
2 Occupancy sensing and temperature reductions – the Accorto uses microwave sensing to detect presence in a room, but rather than switch off immediately it reduces the temperature over a period of time, ensuring that any low levels of activity are not mistaken for an empty room
3. Landlord Lock function – once you've picked your preferred operational mode you can lock those settings in and be rest assured that they cannot be unlocked without the App access
