What happens here

Before beginning the installation, it is crucial to test the circuit breaker to ensure it is functioning correctly. Take the new Square D QOB bolt-on circuit breaker and turn its toggle to the 'ON' position. Then, using a screwdriver, apply a firm impact to the load side terminal of the breaker.
