What happens when a breaker is overloaded?

Electrical circuits are designed to handle a limited amount of electricity. An overload occurs when you draw more electricity than a circuit can safely handle. … If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire.
