Ok, *hopefully* one last question on fusing. I will have 200a terminal fuses on each battery, currently I will have 1AWG wire from house battery to 1/B/2 switch, and 4AWG from backup battery (it's what I have at this point, but will eventually upgrade to 1AWG). Will add echo charger connected at switch 1 & 2 posts per suggestion.
Starter cable will run from Common post on switch, currently 4AWG, also to be upgraded to 1AWG. AM I good to connect the starter cable without an addition fuse, on the assumption that the terminal fuses will protect the circuit from battery to starter in case of a short? I'm struggling with determining which fuse type to use and how to mount if I DO fuse the starter cable.
Bumping back up on inquiry regarding fusing the starter cable at the 1/2/B switch.
