Based on ship weight from Grainger on 100ft, 2/0, 1/0 and 1 gauge wire. The weight per foot on each is:

2/0 = .49
1/0 = .39
1 = .31

So a 10 foot run of each wire won't vary more than about 2 pounds. Not real significant.

True, I checked it - but if you are using #0 welding cable, the weight difference will be significant.



That is welding cable weights.

I'll still take a heavier fine strand wire that weighs 4# per 10 ft than save some weight on a 2.5# per 10 ft inferior wire.
