[QUOTE="adulbrich, post: 8767289, member: 661255"] [ATTACH type="full" alt="33001"]33001[/ATTACH] Google says 4/0 can carry 310 amps. Although, I don't trust those numbers. IIRC, 1/0 oversized car audio OFC wire is rated for 300A. So, I'd say reasonably, it should be good for 500-600ish amps. 10k watts, let's say 70% efficiency. 10,000/.7= ~14,280A draw on electrical system. 500A safe bet per run, and you should be good with 3 runs. Although, if you know the current rating from the manufacturer, I could do some better math. I ran 4 runs of Sky High 2/0 OFC when I had quad alts, 32 batteries, and four Vital Power 7k's @.5 nominal. My voltage drop was minimal. That being said, You would probably be ok with 2 runs. I definitely recommend dedicated ground runs as well. That's a lot of current to run through the vehicle body. [/QUOTE]
