In the 2002 NEC section 210.12 (II) Branch-Circuit rating FPN-4 states a maximum of 3% VD for branch circuits and an overall VD not to excide 5%. In section 215.FPN-2 it states the same thing for feeders.
My question is in what case is the 2% used for either the feeder or the branch circuit. Where in the NEC does it state the difference? Why do we generally use 2% for branch circuits? Why not 2% for feeders and 3% for branch circuits?
