Final answer:
When operating circuit breakers, it is important to check that they re-set properly. To do so, you can intentionally trip the circuit breaker and then attempt to reset it. If it successfully restores power to the circuit, then it is operating correctly.
Step-by-step explanation:
When operating circuit breakers, it is important to check that they re-set properly. Circuit breakers are devices that protect circuits from overloads and short circuits by interrupting the flow of current. They have a switch that can be manually reset after tripping. To check if a circuit breaker resets properly, you can intentionally trip it and then attempt to reset it. If it successfully restores power to the circuit, then it is operating correctly.
