What type of cable is classified as CL2?

The classification of CL2 cable refers to a standard set by the National Fire Protection Association (NFPA) and Underwriters Laboratories (UL) for electrical wiring. CL2 cables are designed for general-purpose use in residential and commercial wiring. This type of cable is suitable for low-voltage applications and is commonly used for audio, video, and data transmission.

CL2 cables are required to have specific ratings to ensure they can safely handle certain electrical loads while minimizing risks such as fire hazards. This is why they are used primarily in building scenarios where standard safety regulations apply.

The focus on general-purpose applications highlights the importance of the cable's design for everyday use within building infrastructures, aligning with its intended purpose without exceeding voltage limitations associated with more specialized cables. The other classifications, such as high voltage or external use, do not apply to CL2 and would typically refer to different categories of wiring, which are structured for different operational environments or requirements.
