Which of the following is not allowed to be marked on a CL2P cable?

The option regarding the voltage rating is not allowed to be marked on a CL2P cable. Understanding the restrictions concerning labeling on these types of cables is important for ensuring safety and compliance with codes. CL2P cables are specifically designed for general-purpose communication applications and are used in certain installations according to the National Electrical Code (NEC).

Typically, the markings on CL2P cables include critical safety information such as the manufacturer's name, the current rating, and the serial number, which provide essential traceability and specifications for maintenance and compliance checks. However, a voltage rating is not required to be marked because CL2P cables are intended to be used at low voltage levels and do not need to indicate a specific voltage range. The design and intended applications of CL2P cables revolve around these standards, ensuring they are used safely while minimizing the risk of misuse or confusion with other types of cables, which might have different voltage ratings.
