I am working on an older fountain and installed a gfi to protect the pump and 3 lights. The lights are 120 75w spots, dry. The pump is a small 1/10th hp. This is all on a single 20 amp approx 70 feet away.
My problem is that the gfi randomly tripped and now won't reset.
There are no short in any of the wiring.
Any sugg would be appreciated.
