What is the purpose of plenum-rated cable in air-handling spaces?

Plenum-rated cable is designed for air-handling spaces exactly because those spaces can spread fire and smoke quickly through the building’s HVAC system. The CMP rating means the jacket and insulation are engineered to limit flame spread and produce minimal smoke and toxic gases, helping contain a fire and protect occupants and ventilation air paths. This safety focus is what makes plenum cable appropriate for spaces used for air distribution. Moisture resistance, RF shielding, and weight aren’t the primary goals of plenum-rated wiring. Moisture-rated cables address damp or outdoor environments; RF shielding concerns interference reduction in coax; and weight is not the driving safety factor here. The essential concept is fire and smoke control in air-handling spaces.
