I have a few possible explanations myself, all of which are unlikely. So I?d like to ask for opinions.
About a week ago, while flipping the switch to turn on an item plugged into a kitchen SA circuit, I received a shock. I think that I felt the shock only in my hand, but these sorts of unexpected events do not always make you a keen observer of details. I pulled my hand away, and cursed myself for having touched the switch with wet hands. Then I asked myself why the GFCI did not trip.
The receptacle in question was fed downstream from a GFCI receptacle that I paid an electrician to install about a year ago. The house is 60+ years old, and many receptacles do not have EGCs connected. I have not opened this one, or the upstream GFCI receptacle, to discover whether either has an EGC connected.
I went to the ?Big Blue store,? and bought a plug-in GFCI tester. Plugging it in to the receptacle in question, I saw two yellow lights (i.e., correct wiring). Then I hit the test button, and the GFCI receptacle tripped.
So I still wonder why this GFCI did not trip during the time I was feeling the shock. I also wonder whether it would trip, if there were a future need.
Any ideas (before I list my unlikely ones)?
