[RE-wrenches] Fuses for battery busbars

[Tyrone Houck]

I think I found what I was picturing...has anyone used Marine Rated Battery
Fuses/terminal fuses in a battery combiner situation? Or would I be better
off just bolting a class T fuse in between my lug and busbar.. the class T
almost seems stronger but with more exposed metal..
This application isn't specific to a certain busbar but for discussion sake
picture 4 batteries landing on a MNBCB 1000/2000
