Ground Wire trips GFI for Light - Stray Voltage?

Oct 16, 2014
Marietta, GA
My GFI has one spa light and two pool lights. The spa and one pool light work fine. The second pool light trips the GFI whether there is a bulb in it or not.
I have tested three different GFIs and they all act the same.

The ground wire for the second pool light is connected to a bus that includes the bonding wires.

If I disconnect the ground wire to the second pool light, all lights work without tripping the GFI. I read somewhere that indicates stray voltage.

Where do I go from here?

Cheers, Richard

Replace the light, there is current leakage somewhere in the fixture or cord. That is what a GFCI senses, current going somewhere it shouldn't.
If a light trips the GFCI, it is always safest, and usually the only way to solve the issue. There is no way to repair a pool light.
