My Christmas lights keep tripping my GFI in the rain.
I've got one of those Light Show boxes with 6 different sections of lights plugged into it. When I have all 6 sections plugged in, the GFI trips immediately. However, if I try them one at a time, the GFI doesn't trip.
If there was a ground fault in any of the sections, wouldn't it always trip the GFI? What am I missing? How do I debug this problem?
Can "high instantaneous current" also trip the GFI?
