Does the National Electrical Code (NEC) refer to UTP or fiber cables?

The National Electrical Code (NEC) provides regulations and standards for the safe installation of electrical wiring and equipment. In this context, the NEC mainly addresses high-voltage electrical systems that pose greater safety risks. UTP (Unshielded Twisted Pair) and fiber optic cables are classified as low-voltage communication systems.

Since both UTP and fiber optic cables do not carry high voltage, they typically fall outside the strict regulatory framework set forth by the NEC for electrical installations. Therefore, when considering the role of NEC, it's accurate to say that it does not specifically refer to these types of cable as they are designed for communication rather than power distribution.

This classification allows for different installation practices and guidelines, which are laid out in standards that are more relevant to telecommunications and data networks. Other options might address aspects of safety or usage, but these do not align with the core reasoning behind the NEC's focus on high-voltage systems.
