What is the correct classification for a cable type used for general purposes?

The classification B, CL2, is indeed the correct answer for a cable type used for general purposes. CL2 cables are designed to carry low voltage and are suitable for in-wall applications, which is essential for general wiring applications in residential or commercial settings. They meet specific safety standards set by the National Fire Protection Association (NFPA) and the National Electrical Code (NEC), making them a reliable choice for transmitting data and power in a manner that minimizes the risk of fire or electrical issues.

CL2 cables are additionally rated for installation in spaces between floors and in walls, which supports their general-purpose designation in various electronic installations. This versatility makes them appropriate for a wide range of applications such as audio, video, and low-voltage lighting systems.

The other classifications correspond to more specialized applications. For instance, CL1 is typically used for general-purpose low-voltage applications but lacks the specific rating that CL2 has for in-wall installations. CL3R is designed for riser-rated applications, suitable for vertical installations between floors, while CL3P refers to a type of cable that offers broader applications but is not confined strictly to general use like CL2. Each of these classifications serves particular roles in specific installations, but for general-purpose use
