Pump bonding wire tripping gfi

[WINGMAN01]

Hello group,
I recently got a Inteliflo VS and installed a GFI(previous pump was not connected to GFI).

Everything works fine until I connect the bonding wire to either the copper plumbing or to nearby underground conduit.

This causes the GFI to trip. The original pump did not have a bonding wire connected or a GFI and I'm trying to make the pool safer by adding the bonding wire.

I don't see why this would be happening, for now I've disconnected the bonding wire so I can still run my pump.

Anyone else come across this issue? Any thoughts?

Some GFIs don't work with Variable Speed pumps. Pentair makes a GFI designed to work with the IntelliFlo.

There might be some sort of ground fault issue. If the new GFI still trips, you might want to get an electrician to check the system.

Also, the entire pool should be bonded. Are you saying that the pool was not originally bonded?

Thanks James,
The Pentair 2 pole GFI is actually the one I purchased. I wouldn't think the bonding wire would cause the GFI tripping
The only thing I need to check when I get home in the am is that I might have connected the neutral load from the GFI(the center connector on GFI that says load neutral) to the ground connector inside the VS terminal box instead of the VS ground to the grounding bus inside the subpanel. This might cause it I guess.

Double check that the wiring is correct. If it is and the GFI still trips, it would probably be best to get an electrician. Ground faults can be difficult to diagnose. It also sounds like the bonding should be checked to make sure that it is done correctly.

Thanks James, I will check it in the morning. There is no bonding grid as it is an older pool but I thinking bonding to the copper pipes is better than nothing at all
Hopefully I saved the gfi instruction, I can't remember if the inteliflo only has 2 lines and a ground then where was I suppose to connect the GFI's load neutral to? I should have hired an electrician
