Hi, to give you a quick break down of my situation. I have a converted bungalow that has several generations of wiring and I'm currently trying to add an additional socket (via a junction box) to be located in a loft onto a ring main.
Thankfully in my loft I have plenty of 2.5mm twin and earth running in there, however I'm unsure of which is the ring main. My question is, Is there a way to identify cables externally without breaking into the cable or having a socket to use a voltmeter since all the cable disappears under the floor boards. Essentially I just have a middle of a cable and I was going to switch each ring off at the circuit breaker and see which cable dies and label them up, however after searching online a clamp meter looks like it might work, is this the right way of thinking or is the only way to cut into them when their dead?
Now I have thought about the possibility of them being spurs but I would check the ring continuity once I have cut into the cable but at least this would help me in knowing which cable to trace.
Thanks in advanced (and a air high five)
