We are often asked, how frequently do I need to have an electrical test done.
The use of the property will determine the interval between tests. Typically, this is every 5 years. Some commercial buildings, such as cinemas, are recommended for testing every 3 years. When a circuit is designed to its full load current, for example, a 3kw heater, the conductors will run at a temperature of 70 degrees Celsius. If the circuit is overloaded or has experienced fault current during its life, it will have exceeded 70 degrees. This will have affected the insulation surrounding the conductors. Electrical terminations that are loose also generate excessive heat due to the high resistance across the terminals. With routine testing of the insulation surrounding the conductors, issues can be identified before the insulation breaks down and a short circuit or a fire occurs. Faulty electrical circuits and appliances start 36% of all fires in the UK.
Benefits Of Routine Electrical Maintenance.
Legal compliance
From a commercial perspective, not only does routine electrical maintenance comply with the Electricity at Work Act, but nearly all insurance companies will want to see evidence of ongoing electrical maintenance in the event of a claim. Emergency lighting should have a full battery drain test every 12 months, and fire alarms should be tested every 6 months, ensuring that the full system with all devices is tested annually.
Minimal downtime
There is never a good time to turn off the power and disrupt productivity, but there are times when it is crucial to maintain operations and power failure due to a system going down can invariably happens when it has the biggest impact. Apart from additional repair costs, downtime from getting an engineer on site and lead times for procuring the parts required to fix the fault can significantly impact costs and client satisfaction. Regular electrical maintenance can be scheduled outside normal working hours or during quiet periods, minimising the impact on the business and operations.
Cost savings
Fixing potential issues before they arise can have significant financial benefits. Scheduled electrical maintenance using thermal imaging cameras can detect hotspots along electrical circuits at terminations and at distribution fuses without shutting off power. This can then be addressed quickly and at minimal cost. General wear and tear on cables, accessories, and equipment can also be identified early and rectified before they become a shock or fire hazard, a potential insurance claim, or even a loss of business.
