GFCIs are sensitive - for a reason. I once had a customer when I was an electrician that had an outlet in the dining room that kept tripping (it was protected from a GFCO in the kitchen). Just a bare receptacle, but always tripped the GFCO. Turns out it was under the window that the cat used to look out and see dogs/cats outside and it was marking its territory. Just happened the outlet received the brunt of the marking spray.
Changed out the receptacle and problem cured. The lady wasn’t too happy with the cat, though.
Nothing stinks quite as bad as tom cat spray and this woman didn’t know the cat was spraying the wall? Good grief! She must of had no sense of smell at all!
I bet that room smelled to high heaven of cat spray. We had a woman who had lots of feral cats around. her house smelled so bad it took your breath away when you went in.
Her car smelled, she smelled.
I always avoided going inside her house for any reason. I told the wife I would wait outside, YOU go in.
