Good day
I have a little problem with my ground fault always tripping.

I have an above ground pool with a 1hp pump. I have a wire in a
conduit to the pump. The wire is 14/2 and is about 100 ft from the
panel. The pump will run for about 3 to 4 hours and then the breaker
will trip. I have metered the wire and there are no grounds or
shorts. The only thing that I can think of is maybe the size of the
wire. I did unfortunately run the pump before with out any protection
and the breaker never tripped.
Any suggestions on what might be the problem
Thanks

Kill power and look for crud/dirt in all involved
junction boxes.

Ok I waited around for a couple of hours until the pump tripped the
breaker (15 amp ground fault) . I checked both the hot and neutral
side of the plug for a ground and nothing (my meter goes to 3 million
ohms).
There are no junctions between the breaker and the pump. This is a
new pump only 3 weeks old (1 hp). The one from last year sized up
(bearings got wet) I could not get it going this season and even the
old pump did it last year about half way through the season. Any
other suggestions guys
Thanks


Think of the pool as one plate of a capacitor to ground - may be no DC
path to ground but that doesn't mean there isn't some leakage from the
pump to the water - through the water to the pool - across the pool
membrane to ground. AC only circuit.

Check the resistance between hot and neutral to the water.
