I installed a hallmark 2 wire to replace my dead goulds/frankin, and replaced almost every part of the system, like tank, pressure switch, wire that goes from the pump up to the ground, safety rope etc etc.
One day I got the bright idea to install a squareD 20 amp 2 pole GFCI breaker, ya know, to be safe. The system is already grounded and bonded as well as any could be, but I decided "why not add a helmet protector protector protector". Whole thing worked well until today, adding power instantly trips the GFI.
So I took the feed off of the breaker and rang out the resistance on the feed wires going to the pump, and the reading is around the same if not lower than when I installed it. I expected to see something sticking out like a sore thumb but I didnt get that. So, maybe something internally changed within the hallmark pump. Beats me. I took out the gfi breaker and put the conventional breaker back and it works just fine.
Most of the pump guys say no way to GFI breaker on deep well pumps... So does code require this component that doesnt protect against much as installed? Maybe I read the NEC wrong. I already have more good ground points for this setup than I do for any other appliance.
