Re: how big of fuse between amp and battery
Fuses are there for the protection of wires, to avoid a fire. They are not there for the amp. So, depending on what wire you have, will decide what fuse you run inline. If it's ofc 1/0, get a 300a fuse. If it's CCA 1/0, get a 250a fuse. If it's 4 gauge OFC, get a 150a fuse. If it's 4 gauge CCA, get a 100a fuse.
The fuses in the distribution block are there for the wires after the distribution block. Follow the same rule of thumb for that. If you're running any 8 gauge, usually good for around 60-70a.
