Electrical Wiring in the Home/House Wiring Issue
I added a light receptacle by tying into a 3 prong plug outlet. When I switched the breaker back on, it buzzed for a second then stopped buzzing. The power was out to the whole circuit. I notice that the ground wire on the new receptacle was touching the black power wire. I separated them but the problem still exists. I tested power from the breaker in question and it still works. What am I missing?
Somewhere in the circuit, some wire or connection burned through to the point where electricity won't pass through it any more. You will need to check all of the wiring on that circuit from the breaker box to the point of the problem. Check the wire nuts. If you have the wires pushed into the backs of any outlets, it would be best to take them out, and wrap the wire around the screws on the sides.
