(OP)
I would like to know if all of the cable sizing tables in NEC 2005 are based on the Neher-McGrath method.

Thank you

RE: Neher-McGrath

Yes, in general.  

RE: Neher-McGrath

The program AmCalc is based in the Neher-McGrath method.

By inspection of the result in the enclose table, we could conclude that the values from the NEC ampacity table and the calc using the Neher-McGrath method have insignificant deviations.
