Having tried to wire in a new dimmer switch and managing to blow the entire switch unit! I am seeking advice from anyone who is competant at doing this. I include all possible details below.
The Room Setup: One single switch feeding 3 wall lights, nothing complicated.
The existing switch wiring: When I remove the case I have, two black wires (neutral) wired together to form a circuit. Two earth wires fed into the metal backplate. And two red wires (live) each feeding into different holes on the back of the switch itself, to form the switched circuit.
The NEW Dimmer: Has 3 sockets on the back, marked up as L1, L2, and earth symbol.
I thought the obvious thing to do was to wire one of the live wires into L1 and the other lived wire into L2. I then wired the existing earth leads into the ground socket. I took the earth strap from the new metal dimmer switch and wired that to the back plate ground point. When I turned on the power it blew the brand new dimmer to smither-reans. What did I do wrong???
