Hi need advice for a pull cord thats completly fallen apart at the house we've just moved in to. Knocked the power off and taped them all up for now and have a replacement switch. My Question is how do I know which set of 3 wires is for the load and which is the line? basically have about 3 inches of wire through a hole in the ceiling and ceiling is plastered so can' easily check it back to the shower... Any help really appreciated.
