Which statement about CL2 and CL3 cables is true?

• A. CL2 and CL3 are suitable for general purpose use, not risers, ducts, or plenums.
• B. CL2 and CL3 are plenum cables.
• C. CL3 cables are rated up to 150 volts and CL2 up to 300 volts.
• D. CL2P and CL3P are used for riser applications.

Answer: (A)

CL2 and CL3 describe general-purpose, in-wall low-voltage cables used for standard interior wiring. They’re not meant for spaces that require special fire-rated behavior like plenums or risers. For those spaces you use plenum-rated cables (CL2P or CL3P) or riser-rated versions (CL2R or CL3R). So the statement that CL2 and CL3 are suitable for general purpose use, not risers, ducts, or plenums, is the correct one. The other options mix up where the P-rated cables belong or how these ratings apply.
