I had such a faulty GFCI on the hot tub. It would trip at random

it did, now it's been a year and the spa never trips.

My system is a regular 110V 15A spa.

You may have had a GFCI with a trip level close to the 4 ma lower
leakage limit than the 6 ma upper limit.

There's some pretty good "hands on" stuff about GFCIs he
