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.
Can a blown fuse be switched back on?
The breakers reset and can be “switched back on”–so there is no need to replace anything. Much of the time, it’s technically inaccurate to refer to a “blown fuse,” so in this article, we’ll offer you some new concepts and vocabulary to describe your various electrical concerns.
Why is blowing a fuse a safety precaution?

What do fuses and circuit breakers look like?

Can a type’s fuse be un-screwed from an adapter?
The Type-S fuse can, however, be un-screwed from the adapter when the fuse has blown and needs to be replaced. S-type fuses are also called rejection-base fuses or tamper-proof fuses because they will reject or prohibit the screwing-in of the wrong-sized fuse.
