I want to hang a TV on the wall with a single socket behind it. I want to use a 13 amp fused switch supplied from a double socket, that I want to get rid of, but in order to keep the ring main intact i will need to put the 2 live wires, 2 negs and earth from the existing socket into the supply terminals of the fused switch with the load cable going to the single socket behind TV. Will this work?
