Cody.

The cca has a higher resistance and watt loss so more voltage drop

[mnrookie]

What about 2/0 CCA compared to 1/0 ofc. The 2/0 CCA is still cheaper per foot and doesn't require extra fuses/terminals as would 2 runs of 1/0 CCA.

[Smoove]

What about "brand X" oversized CCA 5243 higher strand count vs 1/0 ofc? Really I don't wanna see this thread drug out more, but where does oversized CCA fit in here?

[_paralyzed_]

I volunteer to eat the limp biscuit at the end of this circle jerk!

well here is a little math i did....

1 20ft piece of OFC 1/0

500A load, loss of 1V and 500w

2 20ft pieces of CCA 1/0 (so 250a per cable)[this being less money than 1/0 OFC]

250A load x 2 (so 250 per cable), loss of 0.85V and 425w (212.5w per cable)

Tony, is this correct? or is it there more to it than just dividing by 2 when using 2 cables instead of 1?

Here is a price comparison also for the wire I am using for these tests. Each wire is 52" long, but for ease of pricing I am going to go with 4'

(these are considering power and ground hook ups)

1 run 1/0 cca

14.83v/2987w/13.56v

$18.48($2.31 per foot)

$12.80($80 per 50' spool)

2 runs 1/0 cca

15.13v/3175w/14.11v

$36.96($2.31 per foot)

$25.60($80 per 50' spool)

1 run 1/0 ofc

14.95v/3131w/14.02v

$29.12($3.64 per foot)

$27.52($172 per 50' spool)

1 run 2/0 ofc

14.91v/3274w/14.16v

$37.12($4.65 per foot)

$36($225 per 50' spool)

The single run of 2/0 is the most expensive option, just beating out the dual runs of CCA by $0.18, but it also yielded the best result.

Now to the hot topic. 1 run of OFC vs dual runs of CCA.

The dual runs of CCA cost $7.84 more than the single run of OFC and yielded only 44w more but at .09v higher than the single run of OFC.

Price in red is the wire price per foot. Price in blue is the price if a full spool is bought.

If a full spool is purchased, the CCA slightly edges out the OFC, but now you also have to take into consideration that you will need 2 more lugs, AND a set of dual inputs($30). Now that you are having to purchase dual inputs, that make the dual runs of CCA MUCH more expensive than the single run of OFC.

So what really is the best option?

In my personal opinion, the OFC is the better option. Less runs, less work, and less money overall.

who the hell are you buying 1/0 CCA from that sells it for 2.31 a foot? Should be about a dollar less than that.... shipped.

Basing off of Sky High pricing since that is what I am using to test with.

Knu Konceptz is $87.50 plus shipping per spool and $1.95 plus shipping per foot. If I were to order 16' of CCA from KNU, it would come out to $2.29 per foot shipped.

lol and to think I paid 7 dollars a foot for stinger cca to wire my batts locally, didn't want to wait on shipping
