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, Boxes, Enclosures, and
Cable Routing Assemblies.
(a) Low- and Medium-Power Network-Powered Broadband
Communications Circuit Cables. Low- and mediumpower
network-powered broadband communications cables
shall be permitted in the same raceway, cable tray, box, enclosure,
or cable routing assembly.
(b) Low-Power Network-Powered Broadband Communications
Circuit Cables with Optical Fiber Cables and
Other Communications Cables. Low-power networkpowered
broadband communications cables shall be permitted
in the same raceway, cable tray, box, enclosure, or
cable routing assembly with jacketed cables of any of the
following circuits:
(1) Communications circuits in compliance with Parts I
and V of Article 800
(2) Nonconductive and conductive optical fiber cables in
compliance with Parts I and V of Article 770
(3) Community antenna television and radio distribution systems
in compliance with Parts I and V of Article 820
(c) Low-Power Network-Powered Broadband Communications
Circuit Cables with Other Circuits. Low-power
network-powered broadband communications cables shall
be permitted in the same raceway, cable tray, box, enclosure,
or cable routing assembly 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 Parts I and
III of Article 725
(2) Power-limited fire alarm systems in compliance with
Parts I and III of Article 760
(d) Medium-Power Network-Powered Broadband Communications
Circuit Cables with Optical Fiber Cables and
Other Communications Cables. Medium-power networkpowered
broadband communications cables shall not be
permitted in the same raceway, cable tray, box, enclosure,
or cable routing assembly with conductors of any of the
following circuits:
(1) Communications circuits in compliance with Parts I
and V of Article 800
(2) Conductive optical fiber cables in compliance with
Parts I and V of Article 770
(3) Community antenna television and radio distribution systems
in compliance with Parts I and V of Article 820
(e) Medium-Power Network-Powered Broadband Communications
Circuit Cables with Other Circuits. Mediumpower
network-powered broadband communications cables
shall not be permitted in the same raceway, cable tray, box,
enclosure, or cable routing assembly with conductors of
any of the following circuits:
(1) Class 2 and Class 3 remote-control, signaling, and
power-limited circuits in compliance with Parts I and
III of Article 725
(2) Power-limited fire alarm systems in compliance with
Parts I and III of Article 760
(f) Electric Light, Power, Class 1, 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.
