Just an fyi, when buying a GFIC, they came at human rated, trips at 4-6 milli amp, and at equipment rated, trips at anywhere from 10 - 100 milliamps. Keep this in mind when installing one, I believe your muscles will lock up at around 10 milliamps ( meaning you can’t swim) and it will stop your heart at around 30 milliamps, is this correct Theo?
I will check the notes from my last "Live Electrical Circuits" training (2023) tomorrow and see if that is mentioned.
