From the 31st December 2015, all UK domestic consumer units (fuseboxes, to some people!) which are installed by Currelec and all other Part P Electricians, must be made of non-combustible material (in other words, Metal). We’ve had wood & Bakelite back in the day, followed by some metal ones. Back then, the same people who are getting rid of plastic now, insisted plastic would be better than metal as it’s non-conductive. Now, due to some fires inside consumer units (perhaps due to the installer not tightening screws properly?), we’re back with metal…. Wonder how long it will be before someone suggests Bakelite again…? For more information, check The Institution of Engineering & Technology’s website.
