(1) In Raceways, Cable Trays, Boxes, Cables, Enclosures, and Cable Routing Assemblies
(a) Other Circuits. Communications cables shall be permitted in the same raceway, cable tray, box, enclosure, or cable routing assembly with cables of any of the following:
- Class 2 and Class 3 remote-control, signaling, and power-limited circuits in compliance with Article 645 or Parts I and III of Article 725
- Power-limited fire alarm systems in compliance with Parts I and III of Article 760
- Nonconductive and conductive optical fiber cables in compliance with Parts I and V of Article 770
- Community antenna television and radio distribution systems in compliance with Parts I and V of Article 820
- Low-power network-powered broadband communications circuits in compliance with Parts I and V of Article 830
(b) Class 2 and Class 3 Circuits. Class 1 circuits shall not be run in the same cable with communications circuits. Class 2 and Class 3 circuit conductors shall be permitted in the same listed communications cable with communications circuits.
(c) Electric Light, Power, Class 1, Non—Power-Limited Fire Alarm, and Medium-Power Network-Powered Broadband Communications Circuits in Raceways, Compartments, and Boxes. Communications conductors shall not be placed in any raceway, compartment, outlet box, junction box, or similar fitting with conductors of electric light, power, Class 1, non-power-limited fire alarm, or medium-power network-powered broadband communications circuits.
Exception No. 1: Section 805.133(A)(1)(c) shall not apply if 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 conductors of communications circuits by a permanent barrier or listed divider.
Exception No. 2: Power conductors in outlet boxes, junction boxes, or similar fittings or compartments where such conductors are introduced solely for power supply to communications equipment. The power circuit conductors shall be routed within the enclosure to maintain a minimum of 6 mm (1/4 in.) separation from the communications circuit conductors.
Exception No. 3: As permitted by 620.36.
(2) Other Applications
Communications wires and cables 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. 1: Section 805.133(A)(2) shall not apply where either (1) all of the conductors of the 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 conductors of communications circuits are encased in raceway.
Exception No. 2: Section 805.133(A)(2) shall not apply where the communications wires and cables are permanently 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.
