    Underground wire

    I sent 277v to a lighting circuit and left the numeral and ecg disconnected and the lights work. 12v from the pole to earth and can't find the splice point how is it working???

    Very dangerously.

    You need to describe your entire installation. A drawing would help.

    The fixtures are finding a path for current flow thru the faulted wires, to earth and back to the transformer. Disconnect all the wires and have someone do a fault locate for you. Has this suddenly happened, say after the new fence was put in?

    Couple of questions for clarity.

    Why were you called in to troubleshoot?

    Is it possible these are 480V lights?

    Fun stuff. Bet no one has an as built. My last parking troubleshoot wound up in a buried ground box that no one knew about. The only thing I know to do is start isolating connections till you find the bad junction or wire.

    I'm going to use a wire tracer but wanted to see if anyone could explain how the light is working with no return to the panel
