Hi,
Iwire-I beleive it is disallowed in other sections...as pointed out in this post..

It is not 'disallowed' it is permitted per 725.52(A) if you do not want to follow 725.52(A) you can choose to follow 725.52(B).

Quote
725.52 Wiring Methods and Materials on Load Side of the Class 2 or Class 3 Power Source.

Class 2 and Class 3 circuits on the load side of the power source shall be permitted to be installed using wiring methods and materials in accordance with either 725.52(A) or (B).

If you chose to use 725.52(B) then, and only then do you need to look at 725.71 at all.

So in your opinion I can not run class 2 or 3 circuits in EMT or MC? (Both are chapter 3 wiring methods)

That would be a real problem in a commercial and industrial jobs. [Linked Image]
