[QUOTE="wmk0002, post: 487818, member: 13975"] If it were me, I would size my main accessory fuse (that leads to the bus or whatever) based on the primary wire gauge allowable. You should be individually fusing anything downstream of that so everything and its smaller wires will have protection there. The main fuse is mainly to keep that primary wire from the battery from burning up. I just say size it a good bit bigger than you think so if you ever add on even more accessories down the road you don't have to change that fuse out (assuming it a fixed amp fuse) - just add accessories with correct wire size and fuse as you go and leave the wiring off the battery alone.
