I plugged an electric drill into a subterranean vault outlet and the outlet and 3 overhead lights stopped working? I tested the outlet and got nothing volts at the pigtail....
I tested the outlet and got nothing volts at the pigtail. The breaker was not tripped but I flipped it to be sure. Any design?
Answers: If the outlet and the 3 lights are the only things on that breaker after it would be my guess that your breaker is bad.
If within are other outlets or lights on the same breaker and they work after the breaker is okay and you have a different problem.
Sounds resembling you could have burned a rope with an overload from the drill and everything on that circuit long-gone the point of the outlet will not work until the burned wire is repaired/replaced.
Take the outlet cover sour and look for signs of a short. Look for black burn marks... pitts surrounded by the metal of the box (if it is metal)... or melted insulation... or any two wires touching short insulation between them.
If none of that is the evident answer... you have to save going back toward the breaker box until you find something to be exact not as it should be. Sometimes these type of problems can be very difficult to identify and pinpoint.
If adjectives else fails phone in an electrician. He will enjoy the test equipment to diagnose the circuit and identify the problem, but that will not be cheap.
GOOD LUCK!
try checking ur fuse box or see if u over heated a line my drill always does that
