A cable marked CL2 is best described as which type of cable?

• A. Shielded twisted-pair
• B. A coaxial cable
• C. Power-limited Class 2 or 3 cable for general-purpose use except in environmental plenums, risers, and other environmental air spaces. Resistant to the spread of fire.
• D. Fiber optic cable

Answer: (C)

A cable labeled CL2 is a low‑voltage, power‑limited cable rated for general‑purpose use in ordinary indoor spaces. It is designed to resist the spread of fire, but it is not suitable for environmental air spaces such as plenums and risers. In other words, CL2 describes the insulation and fire‑rating characteristics of the cable, not a specific shield or conductor type, and it indicates it’s appropriate for typical interior wiring needs where powerful sheathing limits are required. Shielded twisted‑pair, coaxial, and fiber optic cables describe different constructions or media, while CL2 specifies a fire‑rating and usage category for low‑voltage circuits.
