What does “CL2P” refer to in electrical wiring?

CL2P refers to a specific type of cable used in electrical wiring, particularly in low-voltage applications. The designation "CL2P" indicates that the cable is compliant with certain safety standards for communication and signal wiring. Specifically, "CL" stands for Class, with "2" denoting its rating for general-purpose use in walls and ceilings without requiring conduit, while the "P" indicates that it is intended for plenum spaces, which are areas used for air circulation in heating and air conditioning systems.

Using CL2P cable is essential in ensuring that installations meet safety requirements, especially in environments where flammable materials might be present, as it has a higher fire resistance. This makes CL2P cable a critical component in low-voltage systems, such as fire alarms, security systems, and data networks, ensuring both functionality and safety.
