Re: what is the point of more runs of 1/0
Depends on length of wire. A 20 foot run of 1/0
is good for 120A to 200A give or take which chart you look at.
You decrease that run the amperage goes up.
IMHO it would be a waste of resources if you did two runs of 4/0. The amount of gain you may see (depending on location of batteries) would be minimal as you can't increase the current capacity of the alt by running 4/0 vs 1/0.
Even 4/0 IMHO would be WAY overkill.
IMHO size the
run appropriately to the size of your alt. One run of 2/0 should be plenty for 250A.
Now if you're running wire in between batteries size the wire based upon your estimated MAX current draw (be it either max output of alt or max system current draw. So say your connecting a front battery to a rear bank. The alt to front battery should be sized according to the length of the run and current required. Usually less then 3 feet which means 1/0 should be more then plenty @ 250A max output. 2/0-4/0 here would be a waste.
Over on DIYMA we had a thoughtful discussion about the Big 3 and Why its so accepted as gospel and automatically suggested if one has dimming issues. The topic was about stock setups (stock alternator) and why one would replace the power run from the alt to battery. Even though from the factory (on newer vehicles) this wire run is sized correctly to the power output of the alt. Basically the premise is people seem to think this somehow increases the power output of the alt when in all honesty your not gaining much of anything from this wire run. The whole issue of dimming or even VD comes down to grounds.
