I've been working on a solar system and 2000w inverter install. Lots of wiring. Lots of heavy duty cables (inverter to batteries). I've also got a battery monitor set up which uses heavy duty cabli...

I do have catastrophic failure fuses on the positive post of each of my twin battery banks. I have had one of them blow. Mine are 350 amps each.
Thanks Pianotuna for letting me know I'm not alone in my thinking! I think I will put a 300 amp fuse on each of my 3 coach batteries.
Then, as a test, I'll disconnect my chassis battery and use my Emergency Switch (to start the engine with my coach batteries) and verify that none of them blow. If the draw from each battery is equal, then I'm guessing the cranking amps they would see would be probably in the 500-800 total (~200-280 amp) range. Hmmm...maybe I'll look for 350 amp fuses just to give myself a little extra margin.
