[QUOTE="sparky2, post: 50667, member: 3253"] :( If its 1950 cables then its probably VIR and will test OK untill you disturb the fittings, if the ends have perished the rubber insulation will just fall off and expose the bare copper cables, there could be a 14s (about 2.5mm ) earth wire around on the sockets which would be run separately ( ie not t+e ). The sockets would have been changed from 5a/15a or wylex which were around in the 50s, it sounds as though its needs a rewire, what would happen if the householder fitted a flourecent or a dimmer switch which req an earth ? you might find the lighting cables are in 5/8 conduit and the joists are probably notched out so the existing cables could act as drawires. best of luck - Stuart.
