A number of years back, I installed a sub panel in my basement. It runs some 240V AC loads and provides a few circuits. Those circuits are in my basement, one dedicated for the sump pump, one dedicated for the dehumidifier.
The dehumidifier, as a non critical load, is on a gfci since I figure it's on the ground and in case of a flood, I'd like it to trip there asa first line of defense. The gfci and dehumidifier work perfect.
I have another circuit fed from my main panel, which is for other basement outlets. The first outlet in the line is a gfci. Recently the GFCI has been tripping, and my wife has correlated it to when the dehumidifier comes on.
There is no chance of a shared neutral, it doesn't happen any other time, so I assume the one gfci is bad. Any ideas why this would happen? Not only is it two different circuits, but one is actually off a subpanel. I'm tempted to swap the tripping GFCI to a regular outlet, but I'd rather not.
I did have a fluorescent light on a different circuit, which would trip a GFCI outlet on the SAME circuit. I plugged the light in via a surge protector and it has not happened since. I guess it needed the filter. Perhaps it's something like that for the dehumidifier? Even if so, it's different circuits this time, so any startup noise issues would need to resonate all the way to the main panel somehow...
Thanks!
