🔌 Enhancing Electrical Safety with Siemens QF120A Ground Circuit Interrupter Review

better than qf120, this qf120a has screws for load and neutral. expected. Local test button and simulated fault with GFCI tester on non-GFCI sockets correctly trigger the switch

The only circuit breakers available locally were combination earth and arc fault circuit breakers, which I don't need in a workshop.

Last week one for my garage door (that's the one plug in the house) kept tripping when the temp went over 100F. After the 3rd reset in a row I plugged an extension cord into the door opener. Guess he didn't turn that switch off for a week, on days with temperatures over 100°. When I went to my local hardware stores, yes several stores, I couldn't find the…
