Do I have a under ground line running to the garage from house that leaking power to the ground?
High electric bill. Only way to cut power to garage is to pull main fuse breaker. In one of 2 fuse boxes in the basement. With the main big square fuse breaker pulled, the garage power goes out. Sooo, went to garage with a hot extention cord from elsewhere, hooked the hot on the extension cord to a wire on a 60 watt bulb socket. Touched other wire to the return on the bulb, lit okay. When I try to touch the non hot wire on the bulb to any wire in the garage (disconnected to box) the hot, return, or neutral, The bulb doesn't light, just blows breaker on good hot wire from elsewhere. Why???? shouldn't the bulb just light if the line is leaking into the ground? It flashes for a second, then extension cord breaker trips.
@timmytaurus,
you could have a current carrying wire black or white crossed/touching a bare/ground wire somewhere, I think the reason your breaker on the extension cord is tripped would be once you hook the black wire it would be sent to the ground (ground fault) and this causes your electricity to draw to many amps/ oversupplying electricity to the ground. buy a cheap multi/voltmeter and continuity test the black to white and black to ground to see if they are crossed. the white/neutral wires are connected in a panel, unless it is a subpanel
