V. Installation Methods Within Buildings

830.110 Raceways for Low- and Medium-Power Net- work-Powered Broadband Communications Cables.

Where low- and medium-power network-powered broadband communications cables are installed in a raceway, the raceway shall be of a type permitted in Chapter 3 and installed in accordance with Chapter 3.

Exception: Conduit fill restrictions shall not apply to low-power network-powered broadband communications cables.

830.133 Installation of Network-Powered Broadband Communications Cables and Equipment. Cable and equipment installations within buildings shall comply with 830.133(A) through (C), as applicable.

(A) Separation of Conductors.

(1) In Raceways, Cable Trays, and Enclosures.

(a) Low- and Medium-Power Network-Powered Broadband Communications Circuit Cables. Low- and medium-power network-powered broadband communications cables shall be permitted in the same raceway, cable tray, or enclosure.

(b) Low-Power Network-Powered Broadband Communications Circuit Cables. Low-power network- powered broadband communications cables shall be permitted in the same raceway, cable tray, or enclosure with jacketed cables of any of the following circuits:

(1) Class 2 and Class 3 remote-control, signaling, and power-limited circuits in compliance with Article

725

(2) Power-limited fire alarm systems in compliance with

Article 760

(3) Communications circuits in compliance with Article

800

(4) Nonconductive and conductive optical fiber cables in compliance with Article 770

(5) Community antenna television and radio distribution systems in compliance with Article 820

(c) Medium-Power Network-Powered Broadband Com munications Circuit Cables. Medium-power network- powered broadband communications cables shall not be permitted in the same raceway, cable tray, or enclosure with conductors of any of the following circuits:

(1) Class 2 and Class 3 remote-control, signaling, and power-limited circuits in compliance with Article

725

(2) Power-limited fire alarm systems in compliance with

Article 760

(3) Communications circuits in compliance with Article

800

(4) Conductive optical fiber cables in compliance with

Article 770

(5) Community antenna television and radio distribution systems in compliance with Article 820

(d) Electric Light, Power, Class J, Non-Powered Broadband Communications Circuit Cables. Network- powered broadband communications cable shall not be placed in any raceway, cable tray, compartment, outlet box, junction box, or similar fittings with conductors of electric light, power, Class 1, or non-power-limited fire alarm circuit cables.

Exception No. 1: Where all of the conductors of electric light, power, Class 1, non-power-limited fire alarm circuits are separated from all of the network-powered broadband communications cables by a permanent barrier or listed divider.

Exception No. 2: Power circuit conductors in outlet boxes, junction boxes, or similar fittings or compartments where such conductors are introduced

solely for power supply to the network-powered broadband communications system distribution equipment. The power circuit conductors shall be routed within the enclosure to maintain a minimum 6-mm (0.25-in.) separation from network-powered broadband communications cables.

(2) Other Applications. Network-powered broadband communications cable shall be separated at least 50 mm (2 in.) from conductors of any electric light, power, Class 1, and non-power-limited fire alarm circuits.

Exception No. J: Where either (I) all of the conductors of electric light, power, Class J, and non-power-limited fire alarm circuits are
