just have to play the devils advocate here...
358.22 - 'cables shall be permitted to be installed where such use is permitted bythe respective cable articles.'
Art. 334
334.15(B) Protection from Physical Damage -
NM is permitted in a raceway system to protect it from physical damage...
However... where protection from physical damage is not the issue - how do you comply with 334.30? ....Securing & Supporting every 4-1/2 ft. and within 12" of every cabinet, box....
312.5(C) - Cabinet... - 'where cable is used, each cable shall be secured to the cabinet....'
How are these requirements achieved when using a raceway system?
again, just play the advocate and using previous arguments against NM in conduit.
This seems to be one of those arguments that have advocates on both sides of the issue.
Personally, as an electrician I do not install NM in conduit systems; as an inspector I don't get overly excited about someone doing so...I do give the electricians a heads-up that many jurisdictions in the area do not permit NM in conduit.
