After figuring the voltage drop for a particular circuit, if the conductors are required to be upsized, is the EGC ALWAYS required to be up sized?
I know the EGC is based off of the rating of the OCPD and not the area as in 250.66, so how would you know which size to go with? Would it be wise to match the EGC with the new upsized feeder?
Thanks!
