Thereof, what happens if you overload a circuit?
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.
Secondly, how do I fix an overloaded circuit? The immediate solution to an overload is simple: Shift some plug-in devices from the overloaded circuit to another general-purpose circuit. Then flip the circuit breaker back on or replace the fuse and turn stuff back on. In practice, however, it isn't so easy to know that you've found a good, long-term solution.
