Is table 250.122 used to size a motor circuit EGC even though the OCPD may be considerably larger than the ampacity of the circuit conductors?
For example a 125 amp motor feeder (100 amps*125%) with an dual element time delay fuse providing short circuit and ground fault protection at 175% (218.75 amps) would require a EGC sized according to 125 amps or (218.75 amps next higher), 225 amps?
This would be the difference between using a #8 EGC or a #6 EGC.
