Grounding Tapped Circuits

[maallen]

How are equipment grounding conductors to be sized for tap conductor ciruits? Same size as the tap conductors or by table 250.122 based on the upstream OCPD?

Yes, by 250.122 and the size of the OCPD protecting the feeder being tapped.

May I add that they do not have to be larger than the tap conductor itself.

250.122 (A) and (G) would be the applicable code sections.
