Just called the homeowner. He said the well man came out and determined that the wire coming from the house to the pump, must have had a knick in it, and was shorting out. (We just had a whole day of hard rain here) They stretched a new wire on the ground between the pump and panel and he said it's been working fine. He's going to get the electrician that wired it initially to come out and pull another wire. Since the circuit didn't have a "dead short", it didn't dawn on me it could be the wire:( I guess one leg must have been almost broke into or knicked, but not enough to keep it from coming on, then the constant load made the breaker trip. Never too old to learn. Thanks..
