I just found myself having to reattach a bathroom light fitting to the ceiling (which, following a failed fat roof, was reboarded and replastered yesterday by someone who can do it better than me, ie properly!).
Although the light worked fine beforehand, I can't quite get my head round it - just for my peace of mind, can someone explain it to me s-l-o-w-l-y?
There were originally two incoming T&E cables; one was the circuit feed, the other the switch cable - so far so good. However, the two lives were patched together in a terminal block, and the two neutrals were connected to the lightbulb in the (metal) ceiling fitting. The earth cables were just twisted together, unsheathed, and stuffed into the ceiling void; and not connected to the earth clamp on the light fitting.
Was this arrangement as potentially lethal as I think it was (especially given that the ceiling void was recently full of rainwater...?
Thanks David
