one egc for 2 or more circuits

[Danpc1979]

I came across a 6 awg egc terminated on a grounding bus in a 12by12by6 inch junction box that had 23 circuits rated 20 amps each circuit.All the 12AWG egc were terminated on the grounding bus in the 12by 12by 6 inch jucntion box with one 6AWG egc going back to the panel with those 23 cicuits. Was this a violation of code?

No, it is more than the code requires. It could have been a single 12 AWG back to the panel or assuming metal raceways the NEC does not require any wire EGC back to the panel.

While I agree with Bob's (iwire) fundamental answer; i.e., nothing was inherently wrong with the EGC setup, may we assume all the circuit conductors, including grounded and ungrounded and the EGC, were enclosed in a common raceway? Was this actually a classified (hazardous) location application? Were any of the circuits multi-wire branch circuits?

one EGC for 2 or more circuits

Thanks for posting those code requirements iwire and rbalex.The raceway was common with all circuits.no classified locations and no mutiwire branch circuit.
