I am running temporary lighting in a hallway ceiling for surface mounted light fixtures in a hospital in nyc. The ceiling is temporary and the lights are temporary scheduled for future demo. All splices will be accessible is there any reason I cant use romex.

Section 590.4(B) (6/4/2014)
Q: Question regarding Article 590 Temporary Installations
590.4(B) the term "cable assemblies" is used to describe acceptable material that can be run exposed, what is meant by "cable assemblies?, is this NM cable that they are taking about?
A: Yes, NM is one type of a Cable Assembly. Refer to definitions in Article 334 and Subsections 590.4(B) and (C).
The use of Romex for temporary lighting leads me to believe that the light sockets are of the type that pierces the insulation.
According to the NYC Electrical Code Amendments, non-metallic cable is not permitted in non-residential buildings. There are no exceptions in the code for it being temporary use.
That is what I am being told. But if thats the case I need to replace 18 floors of temp lighting stringers that were already approved. Replaced with flourescent light fixtures and mc if they dont allow any nm cable. Does not make sense
My guess is that it doesn't make sense because the information is incorrect. Who is telling
The construction agency between the state and the GC. He quoted 334.10 (5) nystate nec and 334.12(A)(2). I feel that code is for permanent construction. I can do whatever they want just feel i should get paid for change.

NM cable is used everyday for temporary installations in all types of construction in NYC. 590.4(C) overrides many of the Article 334 provisions for NM cable. This is from the NYC dept. of buildings:
