Insulated ConductorComplying with manufacturer's AWM Procedure. The designations of all styles of individual conductors used in making up the cable assembly shall be available.
AssemblyTwo or more individually insulated conductors or group of insulated conductors cabled together. All conductors in any group twisted together. If more than one group is used, groups shall also be twisted together. The length of lay of the twisted conductors or groups is not specified. Fillers may be used in a cable but are not required. A barrier layer, if employed, may be a fibrous wrap serving; braid; paper; nylon; oriented polyethylene terephthalate; or a thermoplastic jacket (4 mil at any point) or tape wrap. Such a barrier layer would serve to protect the cable during further processing and would be applied over the twisted assembly of individual conductors or groups of conductors.
CoveringOptional. A nominal 15 mil extruded PVC or extruded XLPE covering may be provided over the conductor assembly.
