Wiring from different Panels In Same Raceway

[Alwayslearningelec]

The specs always prohibits this but I was curious if it was a code thing as well. Thank you................

No, it's not a code thing.

Is it common practice for guys to combines wires from different panels in same conduit ?

It's not particularly common practice but if it's a convenient solution it's allowed, see 300.3(C)

For me, doing resi battery backup, it's a frequent and inevitable consequence of moving a subset of existing loads onto a backup panel.

I'm sure commercial practice is different. The code doesn't care though.

I one had an install that needed 120v and 277v outlets on the underside of a member so I ran one pipe for both systems.
