Default single conductor between panels

I was reading another thread, which is now closed, and @99cents made a good point. I had a follow up question, but obviously can't, so hence this thread.

All this talk of portable generators, neutrals, bonds and such got me thinking...

If you're wiring a small gen panel, and you've nippled between that and the main. And you need to extend some ccts, to bring into gen panel. Skinning the sheathing on nmd and extending it to reach new breakers, is a violation - as you should be using single conductor?

Whether it's a chase or close nipple, it's still a raceway, no?

Yes, still a raceway and technically a violation.

I’ve heard many guys argue that short sections of raceway are not considered a raceway but I have never seen a code that says that.

There is a code that exempts conduit fill rules for short, incomplete sections of raceway that are being used for mechanical protection. 12-910(2)

And your also breaking the most misunderstood code in the book, 12-3032(1), using a panel as a junction box for conductors feeding through to other apparatus.

(This is the code that many use for the “no joints allowed in a panel” argument)

I know a guy who knows a guy who stripped out some BX today and stuffed it down a pipe. It may or may not have been about twenty feet. What a hack.

Good point.

Couldn't see the forest for the trees on that one.

Agree...sounds like a plumber i.e., “Canadian Electrician”

(…lectricien Canadien)

In the thread that was closed, the guy used #3 NMD between the meter and the panel. That's not bending a rule, it's breaking it.

I use them fairly regularly and just did on Friday. Job got inspected and passed no problem. Mine were not 20', but are usually stubs from the drop ceiling. My last one was only a couple of feet, but regardless the same situation.

I have also done the same thing using an Octo box or 4 11/16 box, never been called on that either. Maybe it is like the flush / surface plates; some things are less important then others.

Cheers
