We've had loads of rain the past weekend, and now my garage has no power.
I've traced the issue to a GFCI outlet that protects the rest of the circuits in the garage - It keeps tripping.
The Power is run to the garage via an underground conduit, which I believe is standard metal electrical conduit.
I recently pulled new low voltage (ethernet) cable thru secondary conduit that was orignally for Alarm wiring purposes, and noticed that water had infiltrated that conduit. Im assuming the conduit had corroded underground.
Is it possible, if water had infiltrated the conduit that carries the garage power (120vac), that it would cause a continuous ground fault?
I've replaced the GFCI outlet it case it had gone bad, but am experiencing the same behavior.
Thanks for any ideas. I'd prefer to not have to dig up the yard to replace the conduit, but I'm guessing that's where I'm headed.
The garage did have power after the storm - at least for a couple hours. Storm ended around 7pm, and garage had power at least at 830-9pm.
Voltage Testing: Across black (line) and white (neutral) - I get 125 volts, the same I get at the breaker. Across Black and Ground (receptacle box) I get 125v
Across White and Ground, I get 0v.
I think that means I'm safe from any voltage leak. I cannot figure out why it keeps popping though. I've removed the other garage circuits, unplugged the opener and any other loads. I'm wondering if I maybe have another bad GFI outlet. –
