Key Takeaways for This Prompt
CM cables are standard communications cables suitable for general building use with basic fire resistance
Plenum-rated (CMP) cables are required in air circulation spaces like drop ceilings and HVAC ducts
Plenum cables offer superior fire resistance and emit less smoke and toxic fumes than CM cables
Cable selection must comply with building codes and fire safety regulations based on installation environment

SUMMARY
CM (Communications Multipurpose) cables are standard communications cables for general building use, suitable for walls and floors with minimal fire code restrictions. Plenum-rated (CMP) cables are engineered for plenum spaces like drop ceilings and HVAC areas, featuring fire-resistant jackets that emit minimal smoke and toxic fumes. Key differences include fire resistance levels, usage environments, and cost, with plenum cables being more expensive but required for air-handling spaces to comply with safety regulations.

SUMMARY
CM and plenum-rated cables refer to NEC fire safety standards for communication cables. CM (Communications Multipurpose) cables are basic-rated for general use with least fire resistance. CMP (Communications Multipurpose Plenum) cables have the highest fire and smoke resistance, designed for plenum spaces where air circulation can spread fire and smoke. Plenum spaces include areas above drop ceilings and below raised floors used for HVAC return air, requiring the strictest fire safety compliance.

SUMMARY
CM cables are general-purpose communications cables for non-plenum spaces with basic fire-retardant properties. Plenum-rated (CMP) cables are designed for air circulation spaces like dropped ceilings and raised floors, offering higher fire resistance and low smoke/toxic fume emission. The main differences are fire resistance levels, smoke characteristics, and cost, with plenum cables being more expensive but essential for maintaining air quality and safety in HVAC circulation areas.
