Is it acceptable to disconnect a circuit in a panel and splice it to another panel? I was told by an instructor years ago that I need to also transfer, (splice and extend) the neutral for that branch circuit but not the grounding conductor. He said the neutral must terminate in the same panel as the circuit breaker source for that branch circuit. Thank you.

At the moment, I cannot think of anything from 200, 210, or 300.3(B) that would directly say that for a plain jane brch ckt, you must terminate the noodle/egc in same panel as the hot. I think one of the prohibitions for that would a MWBC- other than that drawing a blank.

Not near book right now.

It must so the currents of both conductors (hot and neutral) cancel by passing through the nipple, or at lease same enclosure openings.
 
This concept is contradictory because you could have a switch with just a hot leg and a switch leg in a raceway of unlimited length because the currents cancel yet if you extend the conductor as mentioned in the OP into another panel and back it's a violation. :roll:

Not to sound stupid but.....

What confuses me here is that it (300.3-B) doesn't mention "enclosure" in the language- only raceway, aux gutter, cable tray etc



Found it- 300.20(A):)

I agree, 300.20(A) is one of the main things to watch here.

depends on exactly how things get routed, and possibly if the second panel is supplied by the first panel.
