We have electricians who want to run control wire from a device back to the control panel by taking conduit up to an interstitial space then free-air running it back above a control panel and dropping it in conduit to the panel. The interstitial space is technically not a plenum as while it has Make Up Air units, they are piped to the outside and to the occupied space. There are exhaust fans on this level though. Do I need plenum cable or would riser cable work here.
I get the feeling that this is a gray area and it would depend on how your inspector is feeling that day.
