Prevent hazards with the KT1700 single pole tester

In recent years, there has been increasing concern in the industry regarding PEN faults, a specific type of network fault with potentially lethal consequences. Whilst the rise in PEN faults is being acknowledged and investigated, it’s important to note that these are not the only way that hazardous situations - including touch voltage and diverted current flow - are created. In particular, there has been an increasing number of incidents where engineers have come into contact with live metallic parts (e.g. metal casings or equipment) during installation or maintenance activities. These contacts can and have led to fatalities. Touch voltages and diverted currents Touch voltages: This occurs when there is a fault in the system that results in no return path for current (i.e. due to a broken or disconnected earth or neutral, combined with other faulty wiring). As a result, metallic parts (such as a distribution board, boilers, or control panel) that are connected to the electrical earth could be raised to a dangerous potential. Diverted current: This is a more complex fault, where the current may flow through unintended paths (e.g. through earth or neutral conductors). Even though the circuit might appear to be functioning normally, diverted current can present serious dangers. Issues with current safe isolation procedures The current safe isolation procedures in place often do not specifically account for or test for touch voltages and diverted current. Even though the best industry practices for safe isolation and proving dead are followed, these two specific hazards are often overlooked. The proving dead process usually involves opening enclosures or testing electrical terminals to confirm that the equipment is not live. However, this step can be potentially lethal if there is already a touch voltage present. Test before touch: The missing step The concept of ‘Test Before Touch’ is well established and often taught to engineers. However, it’s usually focused on high-voltage equipment and not before entering or touching low-voltage equipment like distribution boards, control panels, pipework, and appliance casings (e.g. boilers or motor casings). In practice, engineers may not always adhere to this guideline, especially when handling parts of the installation that seem to be disconnected or 'dead'; they may neglect to check if there is a touch voltage or diverted current present. The KT1700 for hazard detection When it comes to electrical safety, you should not be guessing. The KT1700 single pole contact voltage tester from Kewtech is your first line of defence against hidden electrical hazards on metalwork and equipment. Make direct contact with metal enclosures, distribution boards, earth bonding, and pipework before you go near them and get a clear, instant warning if hazardous voltages are present. That’s real peace of mind before you touch. Unlike non-contact voltage testers, the KT1700 contact voltage tester delivers reliable voltage and live phase detection, helping you identify increasing network hazards such as PEN faults, diverted neutrals, phenolic breakdown, and touch voltages early.

Greenwich subway lighting upgraded with Acrospire LED system

British LED lighting manufacturer Acrospire has completed an LED lighting upgrade across 12 pedestrian subways in the Royal Borough of Greenwich, improving visibility and supporting safer public spaces. Delivered in partnership with Greenwich Council and contractor FM Conway, the project replaced ageing lighting installations that had resulted in inconsistent illumination and reduced visibility. The scheme was supported by funding from the Mayor's Energy Efficiency Fund (MEEF). Acrospire carried out lighting surveys and designed bespoke schemes for each location using its VandaWay lighting system. Instead of traditional ceiling-mounted luminaires, the fittings were installed along the upper edges of subway walls and, where appropriate, on railings. The company says this provides more consistent illumination across both walls and walkways, improving visibility while reducing shadowed areas. The lighting designs also accounted for changes between daylight and night-time conditions, with illumination levels tailored to support visibility when entering and leaving each subway. Lighting design tailored to each location According to Acrospire, Bryan Close Subway achieved daytime illuminance levels of more than 300 lux, while night-time lighting was reduced to minimise glare without affecting visibility. At Waterlily Walk, where the subway runs alongside a waterway, the lighting was designed to minimise light spill into the surrounding environment. Ranjit Reehal, Area Sales Manager at Acrospire, comments, "Subways present a unique challenge. It’s not just about lighting the space; it’s about how people feel moving through it. "By improving visibility and removing dark spots, you create an environment where people can see clearly ahead of them, and that has a real impact on confidence and safety." The installation uses vandal-resistant luminaires designed for public environments, with the aim of reducing maintenance requirements and improving long-term reliability. Alongside improving visibility, the move to LED lighting is expected to reduce energy consumption and support the council's wider carbon reduction objectives. For more from Acrospire, click here.

Smart HVAC: From reactive to intelligent

In this exclusive article for ECN, Sadiq Sayed, SVP Digital Energy Software Business at Schneider Electric, explores how AI-powered HVAC optimisation is transforming commercial buildings from reactive, fixed systems into intelligent, self-tuning assets that cut energy waste and improve performance: Commercial buildings rely on HVAC to keep occupants comfortable and air quality on spec. For electrical contractors, the pressure point is delivery: tighter energy targets, tougher compliance expectations, and more variable loads mean clients want upgrades that can be installed cleanly, commissioned faster, and proven in operation, without ripping and replacing whole systems. That’s where data‑driven HVAC optimisation comes in. Using existing BMS signals, added metering and sensors where needed, plus analytics/AI and digital twins, contractors can help shift sites from fixed schedules and reactive call‑outs to continuous, predictive performance. Done well, it cuts energy and carbon, flags faults earlier, improves uptime, and reduces repeat visits - all while keeping comfort steady. A new generation of intelligent HVAC systems Traditional approaches to HVAC management are no longer enough. Most commercial buildings still operate on fixed schedules and static setpoints, with little consideration for real-time occupancy, weather fluctuations, or equipment health. Over 30% of HVAC consumption is estimated to be unnecessary, resulting in wasted energy and missed opportunities for optimisation. At the same time, facility teams are being asked to do more with less. The building technology skills gap is widening, regulations are tightening, and there is an increased need for more flexible spaces in line with changing business needs. In this context, AI-powered HVAC optimisation is not just a technological upgrade; it’s non-negotiable. AI optimisation for HVAC systems AI brings a new level of intelligence to HVAC operations. By continuously analysing data from sensors, weather feeds, occupancy patterns, and asset health, AI algorithms can predict and adjust system behaviour in real time. They learn the unique rhythms of each building, predicting demand and proactively adjusting setpoints, ventilation rates, and equipment operation. Over time, the AI engine refines its models, learning from every data point to optimise performance. This optimising shift from reactive to adaptive is transformative; buildings become living systems, continuously tuning themselves for efficiency, comfort, and resilience, without constant human oversight. The technology foundation for AI-powered HVAC optimisation AI-powered HVAC optimisation is built on a comprehensive technology stack. At the core are building management systems (BMS), which serve as the nerve centre, aggregating data from HVAC equipment, sensors, smart meters, and other building systems. This foundation enables centralised control and monitoring and is essential for AI integration. Digital twins, or virtual replicas of buildings, are continuously updated with real-world data. AI models simulate HVAC operations within the digital twin, allowing facility managers to test scenarios, predict outcomes, and identify optimal parameters, without impacting actual operations. Digital twins are invaluable for risk-free experimentation and long-term planning. Real-time data integration is another critical component. AI engines ingest data from a wide range of sources, and this continuous data flow enables real-time decision-making, fault detection, and predictive maintenance. Hybrid architectures that combine the strengths of cloud and edge computing are becoming more common. Cloud AI handles large-scale data aggregation and complex analytics, while edge AI delivers real-time responsiveness at the device level. This balance ensures both portfolio-wide optimisation and immediate, local control. Finally, intuitive dashboards and mobile apps empower facility teams with actionable insights, alerts, and performance metrics. Automated work orders, fault diagnostics, and energy analytics streamline operations and simplify maintenance, making advanced HVAC management accessible to teams of all sizes. The path to AI-driven HVAC optimisation The first step is a site audit: what plant is in place, what controls strategy is being used, how is the BMS set up, and where might the electrical infrastructure limit performance (switchgear capacity, harmonics, power quality, protection, and resilience requirements). A structured survey of HVAC assets, energy use, and operating constraints helps pinpoint where controls upgrades, metering, and integration will deliver the quickest wins. Next comes the data layer. AI only performs as well as the signals you feed it, so it’s about getting the basics right: reliable sensor inputs, sub‑metering where it’s missing, consistent naming/tagging, time sync, and clear comms paths from field devices to the BMS/SCADA. For contractors, this is often the make-or-break scope because it’s the part that determines whether optimisation is actually measurable and maintainable. Platform selection matters too. Look for solutions that work with open protocols (e.g. BACnet/Modbus), support hybrid edge/cloud deployment, and can scale from one building to an estate without locking the client into a single vendor or forcing a controls rip-out. Deployment should be treated like a commissioning project, not an “IT install”. Integration, functional testing, alarm rationalisation, and trend verification are essential, alongside practical handover so on-site teams can use the dashboards and act on recommendations. Finally, optimisation is iterative. Ongoing monitoring, periodic recommissioning, and parameter tuning keep performance on track as seasons, occupancy, and equipment condition change - turning the initial upgrade into sustained energy, carbon, and reliability gains.

Survey examines electric van adoption amongst UK SMEs

Nearly one third of UK SMEs and sole traders that rely on vans have already added electric vehicles to their fleets, according to new research from Tempcover, a temporary business van insurance company. The survey of 500 UK sole traders and SMEs found that 30% have already adopted electric vans. A further 27% plan to make the switch within the next 12 months, while 31% are considering doing so over the following one to five years. However, some businesses remain undecided. 9% have yet to decide whether to switch, 5% are considering the move without a defined timeframe, 4% are not currently considering electric vans, and a further 4% say they do not intend to adopt them. Amongst businesses that have not yet transitioned, concerns about driving range remain the most commonly cited barrier, identified by 39% of respondents. High upfront purchase costs (29%) and limited charging infrastructure (28%) were also frequently highlighted. The survey also found that 55% of respondents who have not switched believe current electric vans do not yet meet the needs of their business, while 70% have concerns about their suitability for regular high-mileage or long-distance work. Businesses weigh practical and financial considerations The findings suggest many SMEs are taking a cautious approach to fleet electrification. More than half (56%) of businesses that have not yet adopted electric vans say they would be more likely to do so if competitors made the move first, whilst 52% do not feel sufficiently informed to make a decision. Despite these reservations, 63% expect future government policy and changes in vehicle manufacturing to influence their fleet choices towards electric vehicles. Claire Wills-McKissick, Temporary Business Van Insurance Expert at Tempcover, says, "The transition to electric vans is a process that requires careful planning. This is particularly significant for small businesses, where upgrading a fleet is often a major investment. "The data shows that around a third have already integrated electric vehicles into their setups, whilst others are taking time to assess what works best for their day-to-day operations. "Given the scale of the decision, it seems businesses are focused on ensuring cost, capability, and operational infrastructure are firmly in place before committing."
