If it were NOT allowed, cable assemblies (which includes Romex) would not be explicitly mentioned in Chapter 9 note (9).Originally posted by bennie:
Hurk: You are more descriptive than I, but we resolved the issue. I hope the inspectors who oppose will change their perception.

...Why not run THHN conductors instead of NM cable?
A coil of Romex is easier to handle in many cases. IMO, the sheath also provides an added measure of abrasion protection an individual conductor pull would not have.
When runing EMT to protect cable from physical damage, can it be a complete run say from box to box of more than one full length of EMT?
Why not? I've never had a problem with it with metal boxes. Plastic I'd not go over 10' unbonded, but the code words here are vague.
How do you make the connections? Do you use EMT fittings?
If going into a [metal] box, yes.
Do you use NM connectors and not complete the raceway to the boxes
Halex makes a connector for this purpose.
, if so how do you bond the raceway if it is metallic? How would you conform to 334.30?
Flip the page to 334.30(B)(1) Fishing through pipe is fishing between "access points"
IF you do not complete the metallic raceway to the boxes, what happens to the ground fault current on the raceway/EGC of the NM cable?
Here the code is somewhat squishy using a term like "short runs" for what's allowable in ungrounded protective metallic raceway. What is short? I dunno, could vary by AHJ. My general rule of thumb has been if its more than one standard 10' length, then j-box it at the ends and bond. Halex has a press on insulation sleeve for EMT ends in 1/2 and 3/4 that is useful when sleeving strictly for protection. With rigid, I'll screw on a plastic bushing. With EMT, I'd think a connector and bushing would be in order if not using something like the Halex insulator.
