said by iLearn:It's not because of a short. GFCIs are notorious for false tripping. Simple noise on a circuit can cause one to trip. I can reliably trip a certain GFCI by switching on/off a fan [which is not downstream] few times and the GFCI of the hair drier by plugging/unplugging a shaver maybe 5-6 times in the same outlet.
I just noticed that my GFCI outlet in the bathroom upstairs tripped. That circuit feeds the 2nd bathroom and the powder room as well. That does happens once every few months.
My question is, is this because there is a short somewhere or it happens because there could be too much load on the circuit?
