Because not everyone has access to a wiring diagram, or understands it, I have reproduced here the British Standards wiring colours and what colours do which circuit. So if you see a wire your unsure off then check here the circuit and its main colour and tracer which will no doubt make it easier for those who think electrick are a bit of a dark art.
