Fuse distance from Battery

[DarrenE46 10+ year member]

Hey everyone, I need to know the reasoning why 18" is the optimal distance for a fuse to be placed from the battery. The battery is in the back on my car and I was hoping to use a fuse dist. block but it may be about 24" away from the battery, would this be ok, or should I fuse it than go to the fused dist. block. Thanks!

isn't critically important what length it is, just close enough to the battery so the fuse -> battery lead won't short out on anything. If you can secure 24" of wire so you're absolutely sure (really, really sure) that it won't short out on anything metal, that's fine.

IASCA likes 18" maximum.
