Electrical Query

If a socket ring circuit is broken half way will some sockets work, will no sockets work or will all the sockets work? Thanks for any replies.

They should all work, isn't that one of the reasons for having a ring?

I'm not an electrician but if the circuit is broken, logically it must have some effect on the sockets.

Nope, a ring circuit is, as the name implies, a loop from the CU through all the sockets, etc, and back to the CU. If the ring is broken at some point you should still get power to all sockets, but you lose the advantages of the ring circuit.

Main advantage is that as the current travels in both directions to the load, so the cables carry less current. Also, distance from the CU to the load can be shorter than the distance to the last load on a radial circuit, so the power losses in the cable itself are reduced.

If a circuit has been designed as a ring, I'd recommend keeping it that way. Cables may not be up to the extra current of changing this to two radials.

the ring would become 2 radials both fed from one oversize breaker in the consumer unit,this would be illegal and dangerous.
