Circuit neutrals for a gen panel

[LarryFine]

I'll probably just pull new circuits from the TS to the sub where I'll splice the ungrounded and grounded conductors in the usual and proper manner and, if allowable, just terminate the grounds on the sub's equipment ground bar. How about that?

Absolutely. If this panel is basically a sub-panel with a pair of interlocked mains, and has a neutral bus, then yes, wire the circuits into it as uaual.

Thanks Larry,

The sub in my post is in addition to the TS, that's where the circuits the HO wants on the generator are. Of course in the TS I'll treat it as a sub panel, but what do you think about me terminating the grounds to the ground bar (Instead of wire nutting them all together) in the sub panel which will now act as a j-box for these circuits.

Grounding or grounded conductors?

If grounded, you would be paralleling the conductors, and it is strongly implied in Section 310.4(A) that such is not permitted for small conductors.

If grounding, it is accepted and often required to parallel those conductors, and it is fine. We all do it all the time.

Hey Volta, Thanks for the reply. I meant the grounding conductors would go to the ground bar, I more or less tried to clarify that an earlier post.

Either method is fine, as long as the common (feeder) EGC is at least as large as that required for the largest circuit or the feeder, whichever is larger.
