My living room dimmer lights did not work properly so I decided to open the switch box to check the wires. It is a 2 gang 1 way switch. When I opened it, there were four red wires and one yeallow/green (I guess it is earth?)
For some stupid reasons I mixed up all the wires and I tried to reconnect it. Sofar I've managed to identify 2 red wires to the lights, and one red live wire from supply. The other red one I have no idea what that is since it does not have any power (I tried to connect it to the light wire and it did not work). This one was the one that connected to C on one side, and lenghthened to C on the other side. Since I didnt know what it was and it didn't have any power, I taped it up, connect one light wire to L1, one supply live wire to C. When I turned on our main switch, the light in the living room is fine (only one of them working since I could find only one live suppl wire). However I now realised there are no lights whatsoever in the kitchen. Outlets are still fine.
Anyone has any idea where I've gone wrong?
Am I correct in saying there should be 2 live wires from supply and 2 wire to bulbs? Did I somehow managed to break one live wire, hence break the rest of the light circuit?
I'll call an electrician next week but in the meantime any pointer is much appreciated.
