    How to earth SWA to external EV charge point

    I am looking at section 722 of 18th edition for EV charge points. Section 722.411.4 imposes restrictions on the earthing arrangements for TN systems.

    Alterations to an installation with a 1980s (?) Wylex board protected by a single external RCD

    Just carried out a pre-work survey (older property and I wanted to check it over) for a client that wants a few extra sockets and other bits and bobs. The installation has a 5-way Wylex board (I’m guessing 1980s - white/cream plastic) which has had RCD protection added externally at some point -...

That time has now come and I...
