Why is the NEC's lack of reference to UTP or fiber cables significant?

The significance of the NEC's lack of reference to UTP (Unshielded Twisted Pair) or fiber cables lies in the low voltage status of these cable types. The National Electrical Code (NEC) primarily focuses on safety standards for electrical installations, particularly those involving power distribution and high-voltage systems. UTP and fiber optic cables operate at low voltage levels and do not carry electrical current in the same way that traditional wiring does.

This categorization means that these types of cables have different installation requirements and safety considerations. Consequently, their absence in certain sections of the NEC indicates that these low-voltage systems are regulated differently, often falling under separate standards or guidelines rather than the more robust requirements set out for higher voltage wiring systems. Recognizing this distinction helps ensure that installations meet the appropriate safety measures tailored for the type of cabling being used.
