Plenum rated cabling is required when used in an open ceiling return air environment. That is when the return air for the hvac units use the space between the ceiling of the first floor and the floor of the second floor as a return air plenum. The way to tell is if the return air vent has a duct attached to it. The duct will run to the air conditioning air handler. This condition IS NOT a plenum rated ceiling. However, if the return air vent does not have a duct, that means the air conditioning air handler is using the air space between floors as a plenum. This condition requires the use of plenum rated cabling. If plenum rated cable is exposed to flame, it does not give off toxic gases as it melts.

Recommended for HVAC
CPVC (Chlorinated Polyvinyl Chloride) is not typically recommended for use in return air plenum spaces due to its potential to release harmful gases when exposed to high temperatures or fire. Building codes often require materials used in plenum spaces to have specific fire-resistance ratings and to be non-combustible. Instead, materials like galvanized steel or specific types of PVC that comply with fire safety standards are preferred for these applications. Always consult local building codes and regulations for specific requirements.
