GFI tripping

[kenmac]

Ok. I've got an issue with a GFI breaker triping that feeds an outdoor water garden. I have tried several things that I feel has isolated every link in the system and it still trips...some times. It may go a week just fine or just a few hours.

We have a few GFI breakers for indoor bath rooms. Off one of these GFI breaker circuits, the line feeds the pond pump.

1 I replaced the pump that had worked fine for over a year, still triped
2 Pluged an extension cord into a garage GFI recptical, still triped
3 Changed wires in main breaker panel from GFI #1 to GFI #2, still triped

So the entire original run, breaker/wire/out door recptical and pump have been replaced with new or as with the breaker just switched. The wire being eliminated via an extension cord may not be a good test. The pump is a utility pump used to pump out a wet basement and maybe the small GFI recpt in the garage could not handel the load? So maybe I need to run a new pc of romex to a new recpt by the pond. This is no easy task because the wires are in a wall!

Any ideas?

I only use these things when I have to. I wired the bathroom exhaust fan
through a GFI.sometimes it would trip sometimes it was fine. I found out that it was sensing feed back from the electrical motor on the exhaust fan & would trip at times I re- wired the fan & bpassed the GFI. Yours mabe sensing electrical feed back from your pump motor

Bird,

I will try a clean job. As far as other coments about over heating. It has trip with just a few mins of time. So not likely

i've had the same problem: my pump house has 2 separate circuits: one 240V for a pump: and a totally separate 120V line for another pump and lights: i use one of the in line GFCI boxes to put power to tools when i'm working on something in or near the pump house: and it will kick when the all sorts of things happen: like the 120V pump kickin on, or sometimes when i turn the light on: and those aren't even hooked to the GFCI box.
