Lets talk power wire!

CCA Wins hands down, here is why.. Lets say you have a huge power bracket you need to reach.. say 800AMPs. (Prices from KNU)

250A for CCA --- 300A for OFC

CCA $87.50 50FT --- OFC $187.50 50FT

4 Runs of CCA 1000AMP capacity total cost $350 --- 3 Runs of OFC 900AMP capacity total cost $562.50

Not to mention the lower voltage drop from running parallel fuses...

Then factor in the voltage drop from running CCA...

Minimal at best, if not completely unnoticeable.. KNU wire is the equivilant of 00AWG. and 00 OFC has an ohms per meter of .000255

If you ran a full 50 foot line your resistance would only be .004ohms.

CCA is not that much higher.

But if your saying $200 dollars and a lower total current capacity justifies (MAYBE) seeing .01V higher voltage, ******* go for it. The pros do, but for every day Joe, and even mid range guys, no, its not worth it imo

How very scientific.

Did you bother to click the link posted earlier in this thread? Notice the power delivered difference, not exactly negligible in my opinion.

Here's a little info I found that I thought was interesting. Notice the heat difference and the clamped power.

I blame science, or Raptor Jesus

Also, CCA is corroded more easily, especial in wet environment

There is a reason ofc is more expensive. It's not all about current. That's like saying amps should only be priced based on wattage.

Because the price of copper > aluminum? lol

I'm just interested in knowing if I should spend the extra money since I only plan on running around 1000 watts total.

I'm not gonna read through the thread to see what everyone else said. But, if you're only running 1kW and DON'T want to upgrade ever, you only need 4 gauge, preferably OFC. If you do think you might upgrade you'll likely be fine with CCA 1/0, because that can still support a current of 250a on an average length run.
