With reference to the above post and diagram - which ive found very helpful;
I have 3 grey wires hanging from a ceiling, each of which has 3 cables within it; red, black and earth (also black but different casing - and all 3 wound together).
Im trying to replace a ceiling rose / light,etc, but am unsure how to tell which cable is which. ie: a)cable from previous light in chain, b)cable to next light, c)cable to switch.
Is there any easy way to tell them apart please?
*note, the building is an old concrete structure with no access to cables other that at the rose / switch / fuse box, etc.
Thank you.
