Are you sure that those lights are line voltage?I was working on a fish pond where something was tripping the GFI. This GFI was protecting the underwater lights, a fountain pump and some landscape lights around the pond. I found the problem to be the fountain pump.
My first question was: Is this a 10uA problem or a 20A problem? I used my ohm meter and got a very low reading from the 3 pond lights in parallel.
I wanted to simply bypass the GFI to see if the 20A breaker would trip but feared I'd electrocute thousands of dollars worth of fish if there was a flooded light.
It seems that a 60Hz ohm meter (if there is such a thing) would quickly tell you whether you are looking at a light filament, motor winding, or a real short.
Anybody know of a device or technique to deal with these questions?
Normally those are low voltage look for a transformer that may be feeding those lights.
