I have been assigned a new project for an electrical device for use in a "ceiling tile / suspended ceiling" setting. Does anyone know what UL or NFPA plenum ratings I will need on my enclosure, cable, and connectors. Plenum rated cat-5 cable is available, but I am wondering about the connection at the enclosure which is in an air-handling space. Any help / insight would be greatly appreciated.
