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...

The amp draw won't be forever, the device will fail eventually. I guess I'm just not getting this. I can see the point of a circuit breaker on a 120V circuit cause you can have many devices that can draw more than the wire rating. I can also see protecting inadequately sized wiring (which is common in RV's). But if I have big honking wire, it's not going to melt with a current draw under it's rating. At least I don't think it would but that's why I'm asking.
The fuse is protecting from shorts on a circuit. Worn or cut insulation on a cable. A loose connection sparking.

I always thought fuses protected everything on the circuit, not just the wiring.
