UL 444 BULLETIN

Abstract

This standard applies to 60 &#8211; 250&#186;C single- or multiple-conductor jacketed or unjacketed, integral or nonintegral 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 are not prohibited from containing 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. <br>This standard applies to communications cables that are intended primarily for installation in accordance with Section 60 of the <em>Canadian Electrical Code</em> (CEC), Part I, and Article 800 of the <em>National Electrical Code</em> (NEC), ANSI/NFPA 70. They are rated for 300 V applications but are not so marked. <br>Note: See <em>Appendix A for a complete list of wire types covered by this Standard and the specific electrical codes for which they are intended.</em> <br>This standard does not apply to communications cords. <br>In Canada,&#160;<u>the Type "-LP"</u> and the <u>Type</u> "-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. <br>If a value for measurement is followed by a value in other units in parenthesis, the second value may be only approximate. The first stated value is the requirement.
