Communications Cable
 

Guide Information for Electrical Equipment for Use in Ordinary Locations


USE AND INSTALLATION
This category covers communications cable which is a single conductor coaxial cable or a multiple conductor jacketed cable for telephone and other communications circuits for use as described in Article 800 of ANSI/NFPA 70, "National Electrical Code" (NEC).

This cable is used as wiring from a protector to a telephone or other communications equipment within a building, and for use as interconnecting wiring between parts of a communications system.

Except for special locations specifically required by the NEC, communications cable, in general, is not required to be installed in conduit or raceway.

This category does not cover fire-resistive cable intended for installation in electrical circuit integrity systems (see Electrical Circuit Integrity Systems (FHIT) and Fire-resistive Cable. (FHJR)).

PRODUCT MARKINGS
Communications cable is identified by marking on the surface of the jacket or on a marker tape under the jacket. This marking includes one of the following Type designations:

CM — Indicates cable intended for general use within buildings in accordance with Section 800.154(E)(1) of the NEC. This cable does not spread flame to the top of the tray in the Vertical-Tray Flame Test in UL 1685, "Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables."

CMG — Indicates cable for general use within buildings in accordance with Section 800.154(E)(1) of the NEC. The damage height of this cable does not exceed 4 ft 11 in. when tested in accordance with the CSA FT4 Vertical-Tray Flame Test in UL 1685.

CMP — Indicates cable intended for use within buildings in ducts or plenums or other spaces used for environmental air in accordance with Section 800.154(A) of the NEC. This cable exhibits a maximum peak optical density of 0.5, a maximum average optical density of 0.15, and a maximum flame spread distance of 5 ft, when tested per ANSI/NFPA 262, "Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces."

CMR — Indicates cable intended for use within buildings in vertical shafts in accordance with Section 800.154(B) of the NEC. The flame propagation height of this cable is less than 12 ft when tested per UL 1666, "Test for Flame Propagation Height of Electrical and Optical-Fiber Cables Installed Vertically in Shafts."

CMUC — Indicates cable for undercarpet use in accordance with Section 800.154(E)(6) of the NEC. This cable complies with the VW-1 Flame Test requirements in UL 1581, "Reference Standard for Electrical Wires, Cables, and Flexible Cords."

CMX — Indicates cable intended for use within buildings (1) where the wire or cable is enclosed in raceway or noncombustible tubing, or (2) in nonconcealed spaces where the exposed length of wire or cable does not exceed 10 ft, or (3) in one- or two-family or multifamily dwellings when the cable diameter is less than 0.25 in., in accordance with Section 800.154(E) of the NEC. Type CMX cable may be marked "Outdoor" to indicate its suitability for installation outdoors on dwellings. This cable complies with the VW-1 Flame Test requirements in UL 1581.

Cable that contains one or more optical fiber members has the suffix "-OF" added to the above.

Cable that complies with the Limited Smoke Requirements specified in UL 1685 is surface marked with the suffix "-LS" or “ST1”.

Cable where it has been determined that all of the combustible materials used in the construction (e.g., insulation, fillers, jackets) are halogen-free in accordance with UL 2885, "Outline of Investigation for Acid Gas, Acidity and Conductivity of Combusted Materials and Assessment of Halogens," may be surface marked with the suffix "-HF."

Cable that may be surface printed with the suffix "-HF" and that also complies with the requirements for low smoke when tested in accordance with IEC 61034-2, "Measurement of Smoke Density of Cables Burning Under Defined Conditions - Part 2: Test Procedure and Requirements," may be surface marked with the suffix "-LSHF."

Cable marked "Shielded" contains one or more electromagnetic shields.

Cable marked "CI (max voltage ____)" is suitable for use as circuit-integrity cable at the maximum voltage to ground indicated, in accordance with Section 800.179(G) of the NEC and is intended for use in free air. Circuit integrity (CI) cable is only permitted to be installed in a raceway where specifically certified and marked as part of an electrical circuit integrity system (see Electrical Circuit Integrity Systems (FHIT)).

 

Communications wire is a single wire or unjacketed multi-conductor assembly of these wires that is intended for use in distributing frames and in cross-connect arrays in accordance with Section 800.154(C) of the NEC. This wire or assembly is marked "cross-connect wire."

Cable that complies with the cable heating test is permitted to be surface marked "-LP" (XXA), where "XX" is 0.5, 0.6, 0.7, 0.8, 0.9 or 1.0 to designate the current rating that each conductor in the cable is permitted to carry in large or undetermined bundles. This rating is optional, and cable marked "-LP" is permitted to be installed in accordance with standard ampacity tables based on the AWG size, temperature ratings and bundle size, even though the current may be higher than the LP rating of the cable.
