Romex in a Conduit

Personally I see no issue with it esp. in the case you pictured. Others may have issue with the listing of the nm cable. I have seen it done hundreds of times and cannot see a problem with it. Conduit is plenty large enough for it.
 
OK,

This is a DIY.

NM is not listed for underground or damp locations.
This NM is heading down a service entrance conduit.

Anything else.
Any code issues with NM inside a conduit?
Underground and Damp is out, per code.

I say NM can pass from a breaker panel, through conduit,
and out to a light, all in one piece of NM.
That is,
No Transition between NM in a conduit, and then NM to the light fixture;
thatis, not required to have THHN in a conduit, into a JB, and NM to the light fixture.
I almost need another picture to show what I mean.

Well I'll just stick my neck an ask about 300.12. Wouldn't the NM be considered non-metallic cable and the cable sheath needs to be continous?

I thought the op was saying the nm was installed in the conduit. I assumed it is not stripped except at the terminations.
 
I'e asked this before, because I always thought it was illegal, and everyone replied that it is fine as the NEC doesn't say that you cannot do it.

In the pic the ground is wrapped counter-clockwise around the mounting screw. Definitely sketchy at best. :)

Conduit fill must be considered , of course. And the grounding method is not code but I don't think you are asking about that.

OK,
the sheath must be continuous until it is inside a JB,
then joints made to transition to THHN for the conduit run,
if a transition is required at all.
And 'that' is the question I have.

Why can't I run NM from the light fixture, straight through to the Panel ?
I think I can, by code.
I can't find a code reason for any restrictions,
but my fellow workers say 'no'.

Well I guess my point was in the pic the cable goes into the cabinet and the cable just sort of dumps into the panel with terminating. If it was just wires 300.12 wouldn't apply but since the cable sheath needs to be continous I thought it has to terminate such as with a NM cable fitting.

What if the NM just punch through a grommet in the cabinet? wouldn't it be similar?

Well is there anything that stops you from bring several NMB cable to a panel and just jamming them through a nipple?... Say I nipple you are using for protection of the cable?

btw, nice egc connection in the pic. i do not mean to imply that you did it.

Jumper,

This is a DIY. Don't even look at his EGC connection, thanks.

Protection is a good idea.
Running from a panel to a dedicated receptical, surface mounted in a garage, imagine that the Romex leaves the panel, up an inclosed wall, across the attic, entered conduit in the garage, down the wall to the Receptical.

I have been told I must transition from Romex, in a JB, and down with THHN.
I maintain that the code allows a continuous run of Romex
from the Breaker Box to the conduit and down to the Receptical.

TwoSkin,
Yes, it would be similar.
The Pic is only a teaser, to spark a discussion. It is a "DIY" thing, pretty bad.

I have another post that may clarify my question.
I thought the pic would help, but maybe it is a distraction.
 
To me, depends on where/how the PVC terminates.
If is just an open-ended section, then, to me 312.5(C) would be the dtermining factor.
If it ends in another cabinet or j box, the 300.12 & 334.30
If underground then 334.12(B) prohibits
