Sorry to beat a dead horse here. Should'nt the VD be calculated for the entire length of wire/circuit..including the wiring of the devices or is it understood that the devices(20a recept with 1a loads) can more than likely be wired in #12 but it will be the "homerun" that may need to be adjusted. Just not understanding why part of the run can be #12's..guess it has something to do with the devices????
If a major portion of the run is done with #10 then the VD would be insignificant to each device in #12. Certainly if the devices were daisy chained for another 200 feet that could be an issue.
Think of it this way. By running #10 from the panel to the first device you eliminated most of the voltage drop so now the rest of the circuit can go back to using #12.
