Im currently looking to put up a new outside light. Now the house is very old so wiring is not brilliant. There used to be an outside light which someone has removed but the cable remains.
The question really is what way do i have to protect twin & earth outside?
Is 20mm or oval conduit suitable? If so how is best to terminate it at the fittings as lights dont really have a way of fittings a gland light you into a junction box?
