I going to extend the ring main into the loft by using junction boxes. I know what you are all thinking that you are not supposed to extend a ring main using junction boxes and why a ring main to the loft. Firstly, I do not have a socket on the landing and I want to run the cable from the landing into a cupboard on the landing and then into the loft and secondly I want more than one socket in the loft. As the ring main? runs conveniently across the landing between the joists then I thought that it would be easy to break into the main there. My question is that with the floorboards up on the landing I'm staring down at three grey cables which I assume one or two are the ring main. How do I know for sure which is the main and not the downstairs lights as I haven't got a socket in sight and I don't want to take up all the floorboards?
