circuits always have the line in going to the switch first NEVER to th light fitting. In the UK we use loop in loop out method and the devic is switched from the loop in the ceiling rose to the switch and back t the device. IE in Ireland the light fitting is dead until the switch i "on" so only two wires to each fitting/device. I am not an electrician (obviously) but what are the implications a the Irish follow EEC rules. Is the UK system outside EEC regulations?
