Need advice on Big 3


Recommended Posts

Posted

So I have a dilemma I have a lot of 4 gauge wire sitting in my garage and i can't really afford 0 gauge right now. Would it just be a waste of time and effort to do the big 3 in 4 gauge? Or should I just wait till I can get 0 gauge.

Id wait. It's really not that expensive.

Personally I would wait until I had the cash for 1/0. It would be a complete waist of time to do it now, then do it later. What you can do now is go get a string and measure out how much 1/0 you are going to need. Also figure out where you are going to run it (away from heat and moving parts, etc) But that's just me.

alts up to like 150 amps will work fine with 4 gauge. you only really need to use 0 when you have 200+amp alts

double up your runs and do it in 4ga since you have a bunch of cable laying around. copper is copper.

You could do 2-4 runs of 2ga and wrap the cables in a sleeve or somthing to make it look cleaner. Technically speaking it would be the same as if you had the 1/0 with enough copper..

still dont see why all of you guys are saying to double up 4 gauge or use 0 gauge when OP hasn't even stated how big the alt is.

If he had enough runs it should be fine from an electrical standpoint. copper is copper right?

whats the point if he has a 100 amp alt, to put 300 amp capable wire on it? it makes no difference compared to 4 gauge, other than OP wasting more money on shit he doesn't need to do.

but like i said, we cant say for sure unless OP (hopefully) comes back and states how big his alt is. and if he plans on upgrading it in the future.
