I am having a weird electrical issue in my living room. There are two circuits for living room receptacles. Receptacles in the west side are in circuit 1 and ones in the east side are in circuit 2.
I bought a used power conditioner and hooked it up to a receptacle in circuit 1. Then after a couple of seconds, the breaker tripped. If I hooked it up to a receptacle in circuit 2, it was OK. I unplugged everything in circuit 1 and hooked up the power conditioner. Same thing --- breaker tripped. So, I don't think it is overload issue. Before I hooked up the power conditioner, I didn't have any issues in receptacles either in circuit 1 or 2. Can any one have an idea where I should look at?
