Hello! My first post on this forum. An interesting thing happened last night. While we were sleeping the power went out (which I don't think is unusual in of itself). The interesting part is a GFI socket next to kitchen sink was tripped. My question is: Is it common for a GFI to trip when power goes out or is restored? I'm rationalizing the trip would happen when power is restored and a surge of some sort happened. Yes?
Was there any lightning? Often that will upset things, or a wind storm. If you get a reduced voltage, or brown out, it will often let go of contacts and trip.

A GFCI checks Voltage/Current difference between the hot leg and the neutral. If there is a minute difference between the two (usu. in the mV range) it will cause it to trip. This is not common, but does happen occasionally with power outages and brownouts.
Power outage, tripped GFI?
