Got a service call while at a supply house. Older man said that his pump (1 HP 120 VAC Hayward) had tripped his GFI and wouldn't reset. So he changed the GFI and it still tripped. Okay, I figured that he installed it incorrectly. Got to his house and it was a dedicated 15 amp circuit with the GFI wired correctly. PVC pipe from the panel, to a switch, then to the box for the GFI. Here's what transpired: changed GFI, still tripping. (Initial start current 17.5 amps (for about half a second), then settles down to 10.8). Ran temp 14/2 from panel to GFI, still trips. GFI in garage runs pump without tripping. Gremlins or...? Thanks, petey.
