I'm renovating a bedroom in our house and went to replace the light switch after doing all the electrical outlets.
The old light switch was a 2 wire, a black and a brownish colour. On the new switch there was 2 screws on one side and 1 on the other and a ground. Then there were 2 holes at the top and at the bottom. So I put the black into the hole at the top then other into the hole on the same side at the bottom. Then tested but it flipped the breaker. When try to eject the wires from the switch, I broke the switch so went and got another.. this time a simple 2 wire one.
I checked online, found that both wires were probably live as it was the only switch for the light. After connecting wires, tested it again and it brew the breaker again!
So I resigned to putting the old switch back in the way it was before I started messing with it. Tested again, and it blew the breaker again! I changed the wires around in case I got it wrong, still same result.
Anyone got any idea what might be going on??
Any help would be much appreciated!
