i wonder if anyone can help
i was replacing my old fan with a new one in my utility room,
the old fan has only L & N and didn't require a earth the new fan is exactly the same and was connected from a f.c.u next to fan, so i thought it was easy enough to do myself, but when i checked inside the f.c.u the earth conductor which was connected to the metal back box was live,
the earth conductor is sleeved and L & N are secure in there terminals and i can't trace where the f.c.u is spured from,
can anyone explain what the problem may be and should i call a spark to come out.
Thanks in advance for anyones reply and also what a great website.
