Can a bad breaker cause a GFCI to trip?
Then, what happens when a GFCI breaker goes bad?
GFCI Breakers can and do go bad, but more than half the time it is moisture somewhere. It doesn't take more than a heavy fog to cause problems. I had a gfi socket do that to me. I had my low volt landscape lights plugged into it and every couple of nights, sometimes 2 weeks would go by, and the gfi would be tripped.
Subsequently, one may also ask, how do I test if a GFCI breaker is bad?
- Push the test button on the GFI breaker.
- Push the switch on the GFI breaker all of the way toward the off position.
- Push the test button again and the breaker should trip.
- Test for power with your voltmeter set on AC volts on the highest scale.
If you want to determine if overloading is really the problem, follow these steps in order.
- Unplug all the appliances connected to the circuit in question.
- Reset the circuit on your fuse box.
- Wait several minutes.
- Plug an appliance back in and turn it on.
- Check to see that your circuit has not tripped.
