Default Big 3 question

I am using 4ga wire for the big 3 upgrade. I am ordering 20 feet. What size fuse would go well with a 4 gauge wire. The big 3 guide says to use a fuse that will work with the wire, not the alt's power.

Thanks

Yea make sure you check their ebay store too. They sometimes will have cheaper shipping from their ebay store than their regular site. I was able to catch some flate rate shipping on their ebay store for like $5

Yeah I noticed that, they have a flat rate of $5 or most stuff. Should 20 feet be enough for the big 3?

20 Ft 4ga wire
Battery terminal adapter (I already have the +)
5 - 4ga ring terminals

Right?

I'd also throw some plastic conduit on that wire and heat shrink the ends to make it more engine compartment safe.

As for the 150 amp fuse for the ALT wire I personally like to use ANL fuses for that.
