A wire can get chaffed or pinched anywhere between the source and the load. That's the purpose of having protection as close to the source as possible. Fuse size also becomes critical because if you over fuse a given size wire and there is a problem, you want the fuse to blow before the wire has time to overheat to the point of burning insulation and possible causing a fire.
