Technical data and wire gauge charts. 

Note: I got the following information from a variety of sources.  I have not personally verified the data shown.

AWG Size	Insulation Thickness	Diameter	Approx. Weight
6	65 mils	0.333 in.	116 lbs./1000'
4	65 mils	0.360 in.	158 lbs./1000'
2	60 mils	0.440 in.	244 lbs./1000'
1	60 mils	0.480 in.	304 lbs./1000'
1/0	65 mils	0.520 in.	370 lbs./1000'
2/0	65 mils	0.570 in.	458 lbs./1000'
3/0	78 mils	0.660 in.	586 lbs./1000'
4/0	78 mils	0.740 in.	779 lbs./1000'

 

Allowable Amperage of Conductors for Under 50V (Per SAE J-378)
Note: Since most wire is rated at 85°C use the 80°C values.
