Hi All,
I'm trying to replace an old double dimmer switch with a new one.
Problem is, I didn't observe how the old one was wired (doh!) so I'm not sure what to do.
I have two grey cables; each one contains a red wire, a black wire and an unsheathed copper earth-wire.
One cable comes from above, the other from below. I'm assuming the one above leads to the lights, the one below probably leads to the power source.
The earth wires are twisted together and sheathed with a green and yellow plastic tube.
My old dimmer switch was plastic and the switch didn't have an earth, so the twisted earth wire used to connect to the metal box in the wall.
The new switch is a metal one (with a brass finish), so I'm pretty sure the twisted earth wire should now connect to the earth terminal on the switch.
The dimmer units on the switch each have 3 terminals marked with L1, L2 and a wavy line with an arrow through it.
Can anyone assist?
Thanks
Pete
