About the AWG wire table, some time ago I tried to see what was
the relation between the AWG gauge and the wire diameter, and found:

diameter in mils=exp(-0.11592*gauge+5.7832)

where exp(x)=e^x=2.71828^x

For 00, 000, and 0000, use -1, -2, and -3.
This expression is precise for #10 and #30, and gives less than 0.1% of
error for the other gauges. (A regression algorithm can refine the
coefficients for better mean precision, if someone want to try).
Most of the other values of the table can be easily derived from the 
wire diameter, conductivity, and density of the material.
