Wiring methods for air handling spaces.

[jamesl]

NM romex cannot be run in parrallel with air handling runs, like between floor joists in a single family. NM can be run through, or perpendicular to such spaces. Can a NM run enter a space described above and exit in another dirrection, like up into a above wall space?
