Hi there, I have a bathroom mirror that I need to wire in. There is already an outlet from the wall - a white sheath containing 4 wires - 1 brown, 1 yellow/green, 1 black and one white (which has been terminated).
The mirror has a 3 way connecting block with a brown, yellow, and blue wire.
I figured that the brown goes to brown, the yellow to yellow/green and then one end is connected to an earth point on the metal backframe and the blue to black. This leaves the white from the wall terminated.
However this does not work.
Can somebody help me please?
