I removed the wires at the breaker. The breaker still tripped instantly.
And prior to that, the breaker would not trip and the circuit was still
open so clearly it's at least part of the problem.
It's only about 15" of wire from the breaker to the timer and another 3'
down to the pump so it's easy to replace all that wire if moisture is
I'll know tonight. The breaker is on the UPS truck for delivery.
I don't know your exact situation, but you may not need the 50 amp breaker to be a GFCI. You can put in a regular breaker and change the load breakers to GFCI or change the outlet(s) to GFCI.
It's possible that the insulation on the wire is breaking down and moisture is causing a ground fault. My guess though is a bad GFCI breaker.

IDK what all that breaker powers, but since it's for a pool
sub panel and it's 50A, it sounds like it's
probably a main breaker in the subpanel. If so, it would provide
the GFCI protection for everything at the pool. Without it, he'd
need a GFCI breaker for the pump, a GFCI breaker for lights,
a GFCI breaker or GFCI receptacles, etc. One versus two or more...
As far as I know, the actual disconnecting of the power inside a gfci is do
ne by an old-fashioned relay. The semiconductors are use to sense an imbal
ance between the two wire circuits/conductors that go thru the gfci, and th
en to cause a relay to open the circuit if the unbalance exceeds a certain
