Large inverter wiring? Low voltage, yes; low energy, no.

No, but if you saw how inexpensive they are (ebay: search "200a breaker" and skip the typical ones we usually use),you might reconsider. That's why it's not a no-brainer for me.

My recommendation is go with the breaker. If you go with a fuse type, best to keep at least one or two spares on hand. Blowing a fuse without a spare on hand can be a "good day" breaker (pun intended)

These are the exact same breakers used in Ranger boats, maybe at a little different amperage, there are 3 of them feeding 3 terminal blocks mounted in the most difficult places to get to

Never seen such an expensive boat with such a junk wiring system in my life.
Not saying the breaker is junk, just the way the boat was wired.
