I have three outlets in a room that are not on the same circuit as the rest of the outlets in two rooms. I have most of the circuits in the house mapped and identified on two breaker panels. The circuits for that most of that floor (the second story) are on the sub-panel.
But - two of the three outlets I'm having trouble with that are on the same wall are on a breaker on the main panel, and I was able to find the circuit and shut them off. However, the third outlet is a real problem. I used a circuit finder, that led to the wrong breaker. I tried flipping breakers with a radio on and it turned off for one of the breakers on the main and one on the sub-panels independently. But even when the outlet didn't "work" (the radio turned off), the wires still showed live.
In a fit of desperation, I put on a glove and cut the wire with a wire stripper. Little puff of smoke, some lights turned off, and one of the breakers flipped. But the wires are still live! Why? What can I do? The wire goes into a wall and I can't follow it to the breaker. Help!
