Hello all.
I am in the process of refurbing my kitchen and I have and old redundant T&E cable coming out of the wall above one of the cabinets which I think may still be live, despite recently replacing the kitchen switch cable and chopping out the extra single & earth cable which was once a switched line to this redundant cable for the old spotlights which were boxed in above the older pine cabinets before the kitchen was refurbed in about 2011. I chopped this single and earth cable out which ran along with the original red and black T&E switch feed, but I know that there will still be a neutral running through this redundant bit of cable as the lighting circuit has a single core (red) and earth feeding the fluorescent light, along with four single neutrals running into it (one of which will be feeding this redundant cable).
What I know about the single core wiring method is that all the line conductors are fed to the switch with one going to the light in the room along with two single neutral cores running from each fitting to the last on the circuit. Because of the layout of my property, we have a porch built onto the side of our house with lighting for the downstairs toilet and utility area, but because there is no upstairs on this part, I know that one of the 3/4 neutral cores will be carrying this spur to feed the last few lights in the porch area, but the real issue is trying to find which one feeds that redundant T&E cable which will probably be junctioned in one of those old crappy JB’s to these old singles below the bathroom floor which I cannot access at all.
The real question to this is, how can I find out which black single core cable to remove which runs to this redundant cable without trying to trace it back and rip down the ceiling to find it? Will I have to do some kind of testing or is it best to call someone out to help with this? As I am going to be changing the old fluorescent fitting for a modern one soon at some point.
Any advice / help will be much appreciated!
Regards Tom
