A 200A feeder for an outbuilding uses 500 kcmil USE ungrounded aluminum conductors. The min size copper equipment grounding conductor run w/ the feeder is:
#2
#3
#4
#6
Now my question is since they didn't state any temp requirements I would go to the 60 degree column in 310.16, and find that a 200 A feeder in aluminum would require only a 350 kcmil. So maybe they had to increase size for VD, does that mean I need to increase my copper ground 2 sizes as well making it a #2?
