(4) Type BLX less than 10 mm (3/8 in.) in diameter in one-and two-family dwellings

(5) Types BMU and BLU entering the building from outside and run in rigid metal conduit (RMC) or intermediate metal conduit (IMC) where the conduit is connected by a bonding conductor or grounding electrode conductor in accordance with 830.100(B)

Informational Note: This provision limits the length of Type BLX cable to 15.2 m (50 ft), while 830.90(B) requires that the primary protector, or NIU with integral protection, be located as close as practicable to the point at which the cable enters the building. Therefore, in installations requiring a primary protector, or NIU with integral protection, Type BLX cable may not be permitted to extend 15.2 m (50 ft) into the building if it is practicable to place the primary protector closer than 15.2 m (50 ft) to the entrance point.

(6) A maximum length of 15.2 m (50 ft), within the building, of Type BLX cable entering the building from outside and terminating at an NIU or a primary protection location.”

Informational Note No. 1: Part V of Article 830 covers installation methods within buildings. This table covers the applications of listed network-powered broadband communications cables in buildings. The definition of Point of Entrance is in 830.2.

Informational Note No. 2: For information on the restrictions to the installation of network-powered broadband communications cables in ducts specifically fabricated for environmental air, see 830.113(B).”

(Added Coun. J. 9-6-17, p. 55278, Art. I, § 1)

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.”
