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. 1.2 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. They are rated for 300 V applications but are not so marked. 1.3 This standard does not apply to communications cords. 1.4 In Canada, Type CMUC, cross-connect communications cables, and the "-CI" circuit integrity markings are not recognized by the Canadian Electrical Code, Part I.
