Adhering to building codes, plenum cables necessitate a low-smoke, flame-retardant jacket aligned with standards like NFPA 90A and 90B. This jacket must self-extinguish during fires and avoid emitting toxic fumes that could disperse via the air handling system. In contrast, non-plenum cables serve areas with lower fire safety criteria, often within walls or conduits, exempt from stringent flame-retardant mandates.
