At one point, I was under the impression that the use of NM Cable (Romex) could be used to provide temporary branch circuitry for commerical construction.

However, at this point, I am second guessing this. Having looked at the Code book, I found no clear definition that NM Cable (Romex) could or could not be installed as a temporary power conductor.

Thanks,

Trevor
 
NM is fine for temporary branch circuits.

590.4(C)

(C) Branch Circuits. All branch circuits shall originate in an approved power outlet or panelboard. Conductors shall be permitted within cable assemblies or within multiconductor cord or cable of a type identified in Table 400.4 for hard usage or extra-hard usage. Conductors shall be protected from overcurrent as provided in 240.4, 240.5, and 240.100. For the purposes of this section, Type NM and Type NMC cables shall be permitted to be used in any dwelling, building, or structure without any height limitation or limitation by building construction type and without concealment within walls, floors, or ceilings.
