Sorry Dan I missed one of your post where you had worked the problem using "Volts" Is the Volts program Mac compatible?
My conclusion:
DiverDan's "Volts" program came up with 2.93% VD or 7.032v.
Using NEC Table 8 and simple VD formula I came up with 2.62% VD or 6.3v.
So the difference is 0.732v.
I assume we both used 240v. as the voltage.
I think we can live with these differences.
Thanks Dan for your insight.
