Protection from damage would be the only reason I could think of....but THHN pulls much easier.....In other, words never pull NM through conduit. Not that it is not allowed, it's just dumb.

Chad,
Not sure of the CEC Articles, but in the `14 Edition of the NEC,
Article 334.12(B) requires NM to be in conduit to provide "protection
from physical damage".
As **cda** mentioned, the AHJ may have some type of requirement
in their Ordinances.........Recommend that you contact the AHJ in
question and ask for specifics.

Oh Well
The code used to allow "or other approved means". I don't have a copy with me but if that's still the case, then NM isn't required to be in conduit anywhere in the NEC.north star said:

**ICE**, ...possibly this Article ?
From `14 NEC, Article 90.4 - Enforcement:
"This Code is intended to be suitable for mandatory application by government
bodies that exercise legal jurisdiction over electrical installations, including
signalling and communications systems, and for use by insurance inspectors.
The authority having jurisdiction for enforcement of the Code has the
responsibility for making interpretations of the rules, for deciding on the
approval of equipment and materials, and for granting the special permission
contemplated in a number of the rules.
By special permission, the authority having jurisdiction may waive specific
requirements in this Code or permit alternative methods where it is assured
that equivalent objectives can be achieved by establishing and maintaining
effective safety.
This Code may require new products, constructions, or materials that may
not yet be available at the time the Code is adopted..........In such event,
the authority having jurisdiction may permit the use of the products,
constructions, or materials that comply with the most recent previous
edition of this Code adopted by the jurisdiction."
FWIW, ...also "thanks" to **steveray** for his input !

More time, more parts = more money

After Checking with my fellow electrician friends in Skokie Ill. It is STILL code in Chicago as well as many communities to only allow conduit or other metallic clad methods. There are two popular sets of rumors floating around as to why. O ne story says it is still fear from the great Chicago Fire and the other says a strong union influence as conduit is more labor intensive. Either way ou will find very few good electricians who will dispute the fact that metallic clad wiring (Especially conduit) is a far safer and superior wiring method. – Eric Long Apr 25 '14 at 19:09
