Friend of mine asked me to replace bedroom receptacles in the house that he just bought. Everything was working fine for a few days and then GFCI installed in the basement by the previous owner had tripped and I wasn't able to reset it since. Of course, he blames me. I checked all wiring, receptacles, switches, etc., There were no obvious short circuits and visible damaged wiring. After I had bypassed GFCI (for testing purposes only). everything started to work fine. GFCI is 2-pole, 20 A. The breaker upstream is 30 A. The breaker upstream is labeled as "Basement/Kitchen", but it supplies power through the GFCI in question only to the basement lights and lights and receptacles (the ones that I replaced) in the bedrooms on the second floor. Kitchen and bathrooms have their own GFCIs that work fine.
The house wiring is very peculiar: mislabeled breakers, receptacles a few feet from each other are connected to different breakers, the wires in one receptacle look ancient, the wiring in the receptacle next to it look new, etc.,
What should I do at this point: to replace GFCI and see what happens or to tell my friend to call an electrician
