What does this mean? I'm trying to put up a light and have been told there's only 2 wires in the light which means I need a separate earth terminal I bought new chrome light switches, got a so called electrician to change them over, he fiddled about for an hour then said he had to go, he left me with the same light I already had up, didn't even attempt it actually.
The hour was taken up with him changing the light switches from the white to Chrome, but now the light doesn't turn on at all. Never put a light up in my life, I'm going to try, please can you tell me what a seperate earth terminal block is. The instructions say I need one.
Would there already be one or is this something extra I need to buy?
