Which statement about CL2P and CL3P cables is true?

• A. They are general-purpose cables.
• B. They are plenum cables.
• C. They are for high-voltage applications.
• D. They are used for riser applications.

Answer: (B)

CL2P and CL3P describe low-voltage, power-limited cables with a plenum-rated jacket. The “P” stands for plenum, meaning these cables are designed for use in air‑handling spaces such as above ceilings or inside HVAC plenum ducts, where they must meet strict flame and smoke requirements. This is why they’re specifically associated with plenum installations. They’re not general-purpose cables, and they’re not intended for high‑voltage applications. Riser use would require different ratings (riser-specific cables), so the plenum designation is the key factor. Thus, the true statement is that they are plenum cables.
