Is the prime directive of electrical safety design.
At one time there were special breakers that supposedly could detect arcing while current still was under the max amp trip point, and break the circuit. I've been out of circulation too long I guess. I do not know if these breakers were successful and if they still exist.

Fuses are to protect wiring, correct? If that is really so then I have a question posed as an example. Suppose I have a 55 amp converter. It is connected to a bank of batteries with 4 ft of #4 wire. ~180 amps is the max rating for 105C #4 wiring. What would be the point of fusing this wire if a catastrophic failure of the unit only sends a max of 55 amps down the wire?

As a couple of others have said, the battery that the converter is connected to is capable of supplying much more than 55A. I fused my #4 wire with an 80A fuse.

What happens if the converter gets mad, and I mean really REALLY mad at you and throws a hissy fit? A direct short with 4AWG is awful, like battery exploding time. Yeah fuses are a pain but what they may protect against is infinitely worse. Remember, Kelly said Murphy was an optimist...
