Ahh, I see where you got your #s now.
going kinda off-topic but..
It's worth noting, tinned copper wire has significantly more resistance for DC. For this reason we have to nearly double the cross-section of speaker wire that most want to sell on ebay if we are using it for DC current.
In AC current it travels primarily through the core of the conductor, but in Direct Current the electrons like travel along the surface of the conductor, hence the tinned part of tinned copper.
This is also why the very best DC cables (Welding cable) you can buy will have way more strands in the cable. Typically like 300-600 strands in large gauge cables. But our AC house wiring is solid wire, cuz it don't care.
So, at lower currents, it's no big deal. But we have to take it into account when we are sizing our wires. And I suppose that if we had bussbars much over a couple feet, we would have to oversize those accordingly too as they are mostly solid conductors.
