You either miswired it or you have the wires touching each other. Pull the outlet back out and check it. The green wire goes to the ground screw. The white wire normally goes to the outlets on the same side as the ground wire. The black wire normally goes on the other side. Are all of the screws tightened down?
question about installation of 20 amp wall plug
I bought a replacement wall plug that is rated 20 amps. I installed it from a 15 amp circuit breaker, in the add it said it was ok to use in 15 or 20 amp. I pluged in a cheap intergraded amp to it and it and my speakers started popping and the amp started to smoke, I unplugged it right away. Was I wrong to assume that it would be ok coming from a 15 amp circuit, can anyone tell me what I did wrong, thanks
