electrical - Why does my gas oven trip the GFCI when turned

May 22, 2018 · Removing a GFCI protection on a device that has a small current leak to the frame seems very risky to me. When this leak become larger, say after next cleaning, you might well shock the cleaner with 20 amps without the breaker even triggering. When a device trigger the GFCI, check the device, don't remove the GFCI. – Jeffrey May 22 '18 at 13:32Get price
