Insulated ConductorLabeled or complying with manufacturer's AWM procedure.
AssemblyTwo or more individually insulated conductors or groups of insulated conductors cabled together to form a round cable. A flat or oval cable may also be constructed with not more than three rows of single conductors or groups of conductors. The length of lay of the twisted conductors or groups is not specified.
