exting a ring main



turn the mains off!

the easiest way to extend a ring main is to put a new soccket in before an origonal one, move one of the existing cables to this new socket, run a cable from this socket to the next new one and form that to the next one etc , then from the last socket back to the origonal socket that now only has one cable.

this way the ring is not broken and there are no joints (other than in the sockets)
