if you still have power at the outlet even after turning off the main
breaker, have your electrician unplug the power company meter. if you
still have power it's coming from the neighbor's house.

I have only 1 circuit breaker panel. I was tiling and need to shut off
the power to my counter outlet. I turned off every breaker but still
had power. How is this possible? Can a breaker fail and continue to
supply power to an outlet when powered off?
