Anyone have any experience with unexplainable gfi tripping?
Brief history. Bought house and inherited pool. Equipment was fine for last 9 years. Last season had lights on one day for a few hrs and GFI tripped for first time ever. would not stay on more than 10 seconds after each reset. I opened first electric box in circuit path and disconnected light closest to panel. Reset GFI and far light came on and stayed on. I isolated problem to first light. Pulled light from niche and opened. interior was bone dry. I figured water got past insulation in cable and light was toast. Time for new lights.
Just installed 2 intellibrite 5G LED's and wired them up. Dang GFI tripped immediately. I thought to myself this cant be happening so I disconnect first light and reset GFI. The new far light comes on and stays on. Same scenario as original problem. I reconnect first light and gfi trips immediately. looks like I may have a defective light. Lets see, so I disconnect all wires going to second light and only wire up bad light to GFI. The bad light (or so I thought) comes on and stays on. Now I'm scratching my head. Each light comes on and stays on when wired to GFI individually but when both lights are connected the GFI trips.
I don't get it. It just doesn't make any sense to me.
As an afterthought I may have not needed new lights as I didn't diagnose any further with the original problem once I isolated the problem to the first light.
