14E-8-840 Premises-powered broadband communications systems.
The provisions of Article 840 of NFPA 70 are adopted by reference with the following modifications:
1.   Revise 840.2 To insert the following language after the definition of "Network Terminal":
"Nominal Current. The designated current per conductor as specified by equipment design.
Informational Note: One example of nominal current is 4-pair Power over Ethernet (PoE) applications based on IEEE 802.3-2015, IEEE Standard for Ethernet, that supplies current over 2 or 4 twisted pairs. The nominal current for 60-watt PoE power-sourcing equipment is 0.3 amperes per conductor, where the current in one conductor can be 0.36 amperes and another conductor can be 0.24 amperes."
2.   Revise 840.160 to read:
"Powering Circuits. Communications cables, in addition to carrying the communications circuit, shall also be permitted to carry circuits for powering communications equipment. Installations of listed communications cables shall comply with 725.144 where listed communications cables are used in place of Class 2 and Class 3 cables.
Exception: Compliance with 725.144 shall not be required for installations of listed 4-pair communications cables where the nominal current does not exceed 0.3 amperes in any conductor."
