What would likely happen if a circuit breaker fails to operate correctly?

When a circuit breaker fails to operate correctly, it can lead to a significant risk of potential damage to electrical systems or equipment. The primary function of a circuit breaker is to interrupt the flow of electricity in the event of an overload or a short circuit, thereby preventing excessive current from damaging conductors, devices, or even starting a fire. If the circuit breaker does not function as intended, the overcurrent can lead to overheating, equipment failure, or in extreme cases, catastrophic events such as electrical fires. This makes it essential for circuit breakers to operate properly, as their failure can result in severe consequences for the safety and integrity of the electrical system.
