how to test circuit breakers with the circuit breaker

Troubleshooting Ground Fault Circuit Breaker Testing

Troubleshooting a ground fault circuit interrupt, or GFI, breaker is pretty straightforward. Troubleshooting the circuit itself can be quite time-consuming. The GFI breaker is designed with a test button incorporated into the breaker itself. Pushing the test button should trip the breaker.

Click on the circuit breaker to release the switch. A bimetallic strip design works on the same principle, except that instead of energizing an electromagnet, the high current bends a thin strip to move the linkage. Some circuit breakers use an explosive charge to throw the switch. When current rises above a certain level, it ignites explosive material, which drives a piston to open
