When is it necessary in a socket to run an earth from the socekt earth terminal to the metal mounting box. I thought it was only when the actual socket fitting was metal?
I have just wired all of my new plastic sockets without this earth connection to mounting box, but have just read that if using metal mounting boxes they should have an earth run to them regardless of plastic socket fitting.
Can someone put me straight please?
