Im going to install a metal double socket onto my garage wall. Because its metal do i also need to earth the back mounting plate on the socket.
If so, does the earth cable have to be of a certain type. i've some spare arctic flex cable i used for an outdoor light and have stripped it down to get the earth cable out, is that ok to use for earthing the back plate?
many Thanks
James
