Oops, I just realized pressing "tab" key posts the comment. Sorry about the previous incomplete message.
So if there's only 1 GFCI in the garage, and 1 GFCI in the kitchen (on the countertop), does that kind of hint they're improperly on the same circuit despite the separate breaker labels in the service panel? The GFCIs didn't affect any other outlets either in the kitchen or garage.
What bothers me is someone tripping the garage GFCI, which in turns trips the kitchen counter GFCI where the crock pot has been running with the evening's beef stew. Resetting the garage GFCI is forgotten, as it doesn't affect any other outlets, so the kitchen GFCI remains without power all day and brews a poisonous meal.
It just doesn't seem right. So I'm grappling with how to report this condition and will keep following this thread so I can convey your perspectives to my colleagues at our regular association meeting. Thanks!
