One of the most notable references is NEC Article 110.3(B), which states:
Do you agree to 1103(B)? Y/N
So what don't you understand? Let's look at the title of the title of the articular (your word) you mentioned.
Nonmetallic-Sheathed Cable: Types NM,
NMC, and NMS
I. General
334.1 Scope. This article covers the use, installation, and
construction specifications of nonmetallic-sheathed cable.

Anything in the instructions say that NM cable cannot be installed in raceways?

There is no instruction or rule that says you can not use non metallic sheathed cable in conduit. The only concern becomes if the conduit would be considered wet/damp.
To say that it can not, would be to ignore the protection requirements of 334.15
Your quoting of 110.3 without some kind of UL (or related lab) document or install instruction makes it a loaded question to which you are not correct.

Now show me the listing testing analysis/data and instructions for use and installation for conduit and raceways.
Please if you would...

And to further drive home the point, if you refer to product code UL PWVX, it clearly states, "This category covers Types NM-B and NMC-B nonmetallic-sheathed cable, rated 600 V, intended for use in accordance with Article 334 of ANSI/NFPA 70, "National Electrical Code" (NEC), and certified in copper sizes 14 to 2 AWG inclusive and aluminum or copper-clad aluminum sizes 12 to 2 AWG inclusive."
That would indicate that there can be a time where conduit is required to be used to meet the requirements of 334.15 and that it would be permitted by UL's use consideration.

If you are interested in diving further into the testing of NM cable you can purchase UL 719 and read their testing of NM cable.

Look at Chapter 9 Tables, Table 1 "says conductors and CABLES". It even tells you how to calculate a cable in a raceway in note #9.
I already have.
358.22
You show us where article 334 prohibits it.
I'll ask too, if you didn't want the correct answer why did you ask the question?

"There is no instruction or rule that says you can not use non metallic sheathed cable in conduit."
Correct...
However in order to use it in the application Conduit or Raceway, the MFG must authorize the application use in the listing.
It is their product is it not!?
You cannot use Romex in a commercial Building...
WHY...it's not listed for use in Conduit or Raceways.
The MFG dictates how their product shall be used in their Approved listing and if you deviate from those instructions then YOU the user except liability for improper use and installation/s.
What does NEC say...
One of the most notable references is NEC Article 110.3(B), which states:
"Installation and Use." Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.
So if you want to Prove me wrong...
Simply show me any Romex MFG listing that shows testing & analysis data, installation instructions providing the application installation in Conduit/Raceway you choose!
I just need the MFG blessing because that's what the NEC wants!
Agreed?!?!?

You've got it backwards. The NEC permits it to be installed in a raceway. The manufacturer would need to PROHIBIT it from being used in a raceway. Show us a manufacturer who prohibits it.

The NEC doesn't directly prohibit it, it is however indirectly prohibited by the MFG listing!!
Your continuing reference top 110.3
The once again, show us where article 334 forbids it.
Then show us that in the manufacturers own white papers or specs.

NEC never uses the word ROMEX which is a type of NMC, now the installation and use application defaults to the listing.
You all need to read my statement carefully...you're NOT!

Modern NM cable is NM-B not NMC.
So basically you came here wanting us to agree with your incorrect understanding of the applicable code articles.
We have asked you to substantiate your claims which you can not do. The best you can come up with is "The NEC doesn't directly prohibit it, it is however indirectly prohibited by the MFG listing!!" So show us where you're seeing this.
