What happens when a circuit breaker trips?

When a circuit breaker trips, it automatically disconnects power to prevent damage. This safety mechanism is designed to interrupt the flow of electricity when it detects an overload or short circuit, which could potentially cause overheating, equipment damage, or even fire. By disconnecting the circuit, the breaker protects both the wiring and the connected devices, ensuring that no further current flows until the breaker is reset and the underlying issue is resolved.

In this context, the other options do not accurately describe the function of a tripped circuit breaker. For instance, a permanent shutdown of the circuit does not occur; the breaker can be reset. Continuous flow of electricity occurs only when the breaker is functioning properly and not tripped. Lastly, increasing electrical flow contradicts the very purpose of the breaker, which is to halt excessive current flow to safeguard the system.
