Holy Toledo, Diver! I'm almost sorry i asked what formula you use! [Linked Image] Except that it's good to know it exists and who to go to if i really want to know! Still, i think i'll stick with my Uglies book for now.

Nevertheless, since i sent you my distances in my last post, did you calculate my voltage drop? I'm curious to see if we match up.. Also, still not sure if you think i should calculate my cmils for each conductor (aluminum and copper) using the total distance involved or whether i should calculate the size of each based only on the distance that conductor runs.
