What happens when a breaker blows?

What does blew a breaker mean?

Instructions

What happens when fuse blows?

Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead.

Can a breaker go bad and not trip?

How many times can a breaker trip?

With 100 amp or less breakers they are tested to be operated 6000 times at rated current and 4000 without current, that is 10,000 operations, most likely they will never see that many operation unless the breaker is being used as a switch and in the right scenario, so highly unlikely this will be exceeded.
