I'm trying to identify the which wires do what under my kitchen floor and it appears that at some time a socket has been removed form the ring main and nothing put in it's place - not even a junction box! just insulation tape around the end of the seperate wires. I 'm sure it's the ring main only all other downstairs sockets work fine even though the ring main is essentially not a ring. Hence the following question:
Will a ring main work if loop is not complete?
