How To Do The Big 3: Tutorial

Recommended Posts

Guest MegaloManiac

well since you are adding wire and not routing it through that box, that fuse doesnt come into play with this wire.

you want to use a fuse on this wire, to prevent fires.

whatever size fuse that the gauge wire will accomodate. 1/0 gauge will accomodate a 300 amp fuse.

a 1/0 guage wire can with stand an easy 250amps of current for bigger lengths. since my length was short(maybe 3-4feet) i went with a 300a fuse even though I only have a 200a alternator. but remember fuse on wire is to protect the wire from catching on fires.

does anyone use circuit brakers???? just wondering dont see many ppl using them. i use 300amp circuit brakers.... for my A.B. VFL 200.1 also. just wondering if anyone else does.

nope. and there is a very good reason why you dont want to use one.

- every time that breakers goes off it degrades and that choice of protection is being less and less reliable every time it goes off.

- a fuse thermally burns up when it has surpassed its limit so you can deem it more reliable than a breaker to do so.

a fuse will be more reliable than a breaker, i rather spend a few a bucks more to keep a stash of extra fuses then to have a breaker that may or may not work when needed

i didnt do it yet. i cant pick up my hc2000's till next month. i have never been able to find a place that actually explained it good enough to where i could vusualize it. this is by far the best explanation/tutorial of how to do it.
