Hi all
I'm renovating a room in our house and came across a badly installed socket with a blackened wire running next to a CH pipe in a notch between floorboards. This socket was spurred off the ring final using bare terminal blocks. We have two 32 A RF circuits - one for kitchen and one for the rest of the house. The socket isn't used so I decided to get rid of it.
I was going to remove the wire to the unused socket and replace the blocks with crimps. I tested continuity / resistance between the conductors of the two remaining cables first. All like conductors (L to L, N to N and CPC to CPC) were open circuit which suggests the ring was broken. With the wires separated (and everything unplugged), 5 double sockets that previously worked don't receive power.
All wires are 2.5mm2 and running off a 32A circuit.
I removed the face from a different socket, on the same circuit, in the next room and tested continuity between the conductors at that point and got a low resistance reading - 0.4 ohm.
In summary, I'm 100% confident this is the same RF circuit and:
o At one point like conductors are open circuit
o At another point like conductors give a low resistance.
Having thought about this it seems I have at least two faults to rectify - the ring is broken somewhere and there is a bridge in somewhere else. Is there another explanation or something specific I should be looking for?
For now I've replaced the 32A breaker with a 16A one from the immersion circuit (which we never use).
