through 362.56, where the
requirements applicable to electrical nonmetallic tubing
apply.
Exception: Conduit fill restrictions shall not apply.
820.113 Installation of Coaxial Cables. Coaxial cables installed in buildings shall be listed.
Exception: Coaxial cables that comply with 800.48 shall not be required to be listed.
820.133 Installation of Coaxial Cables and Equipment.
Beyond the point of grounding, as defined in 820.93, the coaxial cable installation shall comply with
820.133(A) and (B).
(A) Separation from Other Conductors. (1) In Raceways, Cable Trays, and Boxes.
(a) Other Circuits. Coaxial cables shall be permitted
in the same raceway, cable tray, or enclosure with
jacketed cables of any of the following:
(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) Nonconductive and conductive optical fiber cables in compliance with Article 770
(4) Communications circuits in compliance with Article
800
(5) Low-power network-powered broadband
communications circuits in compliance with Article
830
(b) Electric Light, Power, Class J, Non-Power-Limited
Fire Alarm, and Medium-Power Network-Powered
Broadband Communications Circuits. Coaxial cable shall not be placed in any raceway, compartment, outlet box, junction box, or other enclosures with conductors of electric light, power, Class 1, non-power-limited fire alarm, or medium-power network-powered broadband communications circuits.
Exception No. 1: Where all of the conductors of electric light, power, Class 1, non-power-limited fire alarm, and medium-power network-powered broadband communications circuits are separated from all of the coaxial 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 coaxial cable system distribution equipment. The power circuit conductors shall be routed within the enclosure to maintain a minimum 6-mm (0.25-in.) separation from coaxial cables.
(2) Other Applications. Coaxial cable shall be separated at least 50 mm (2 in.) from conductors of any electric light, power, Class 1, non-power-limited fire alarm, or medium-power network-powered broadband communications circuits.
Exception No. I: Where either (1) all of the conductors of electric light, power, Class 1, non-power-limited fire alarm, and medium-power network-powered broadband communications circuits are in a raceway, or in metal- sheathed, metal-clad, nonmetallic-sheathed, Type AC or Type UF cables, or (2) all of the coaxial cables are encased in raceway.
Exception No. 2: Where the coaxial cables are perma- nently separated from the conductors of electric light, power, Class 1, non-power-limited fire alarm, and medium-power network-powered broadband communications circuits by a continuous and firmly fixed nonconductor, such as porcelain tubes or flexible tubing, in addition to the insulation on the wire.
(B) Support of Cables. Raceways shall be used for their intended purpose. Coaxial cables shall not be strapped, taped, or attached by any means to the exterior of any conduit or raceway as a means of support.
Exception: Overhead (aerial) spans of coaxial cables shall be permitted to be attached to the exterior of a raceway-type mast intended for the attachment and support of such cables.
