I've got to have the carpet up in the hall next week. While it's up could i run a single cable from the CU on its own MCB from the RCD side of the CU?? That way i would ahve a neutral!! Is this feasible?? ???

Not a single cable no, would be better to make a new box in the wall and run some new twin+earth to it from a new breaker, or alternatively run another twin cable down from an adjacent light fitting with a permanent live.

You must keep the same neutral that is associated with the live otherwise it's not safe and contradicts the regs.

In other words you can't take a neutral from another circuit on it's own, you must take a live and neutral from one existing circuit, or make another.

The colours didn't seem to marry-up with convention. I would take another 2core from the original light to the switch, and from the switch to the outside light. Two blacks together in a terminal block, one red in com and one in L1 on the new switch.

Sorry LS when i said single cable i meant a 'radial' circuit with t+e. I assume a 6amp mcb is correct?

Lec looks like 2 3 core and earth have been run!! The earth in one being cut off.

Would've made that into the neutral that i required but the ceiling has been overboarded and the ceiling rose is below that!!!

Another job for the future!!

[quote author=L.Spark link=1104513609/15#16 date=1104602038]Well I would think it's unlikely theres a neutral there, however this is where it bugs me becasuse if he had a voltage indicator like we all do it would be found out in a few seconds if there's a neutral, but normal house goers just dont have these things Roll Eyes

More fool them.

IMHO, not buying a multimeter when you want to mess with your electrics is like not buying a hammer when you want to bang nails in.

Yes perhaps

Multi-meters are good but they have there limits, and seeing as you could make mistakes if you don't know how to use one, set it wrong and then find the cable's still live.
