This is the common CSA and UL standard for communications cables. It is the seventh edition of CSA C22.2 No. 214 and the fourth edition of UL 444. This edition of CSA C22.2 No. 214 supersedes the previous editions published in 2002, 1994, 1990, 1988, 1986, and 1984. This UL edition supersedes the previous editions published in 2002, 1994 and 1990.
This Standard applies to 60 to 250 °C single- or multiple-conductor, jacketed or unjacketed, integral or non-integral cables and single or multiple coaxial cables for telephone and other communication circuits such as voice, data, and audio for on-premise customer systems. These cables may contain one or more optical fibre members. For the purpose of this Standard, a coaxial cable or coaxial member conductor is a single conductor with a shield. For the purpose of this Standard, a single- or multiple-conductor unjacketed cable is a cross-connect wire.
This Standard applies to communications cables that are intended primarily for installation in accordance with Section 60 of the Canadian Electrical Code (CEC), Part I, and Article 800 of the National Electrical Code (NEC), ANSI/NFPA 70. These cables are rated for 300 V applications but are not so marked.
See Annex A for a complete list of wire types covered by this Standard and their applicable electrical codes.
This Standard does not apply to communications cords.
In Canada, Type CMUC, cross-connect communications cables, and the -CI circuit integrity markings are not recognized by the Canadian Electrical Code, Part I. In the US, Type CMH is not recognized in the NEC.
If a value for measurement is followed by a value in other units in parentheses, the second value may be only approximate. The first stated value is the requirement.
