Is the nPanel plenum rated?

All of our panels and accessories in metal enclosures are plenum rated for use anywhere in the US and Canada. The exception is Chicago. Chicago requires a sealed enclosure for use in an air plenum.  We do have an approved enclosure for that application but that configuration has not been requested in over a decade.  Also, every space above the ceiling is not an air plenum, only spaces that are used to move return air without the use of an air duct is air plenum space.
