Nec 250.122(g)

[erickench]

Okay. NEC 240.21(B)(1) mentions an overcurrent protection device at the termination of the tap itself. Are you saying that the tap EGC is sized according to this OCPD and not the feeder?

The size of the EGC for the tap circuit is based on the upstream OCPD. That would be the OCPD that protects the feeder that the tap conductor is connected to. In many cases this would result in the EGC being larger than the tap conductors and is one of the reasons why the second part of the first sentence of 250.122(A) says that the EGC is never required to be larger than the associated circuit conductors.
