The Fix: Make sure the faulty device is unplugged and there is no damage to the outlet. First, test the circuit. Then check for any damage on or around the electrical panel. If you see any damage, call an electrician before doing anything else with it. If there is none, flip the breaker switch back to its operating position.

What causes a circuit breaker to blow a fuse?

Any faulty wiring or connected parts risk a power fault (surge), which trips a circuit (or blows a fuse). So, again, the problem is not that the circuit breaker (or fuse) didn’t do its job but rather that there was faulty equipment.
