Rating125 deg C, 600 Vac, Cable flame.
Conductor30 AWG - 9 AWG solid or stranded.
InsulationLabeled or complying with manufacturer's AWM procedure.
AssemblyTwo or more individually insulated conductors or groups 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. A barrier layer, if employed, may be a fibrous wrap serving, or braid; paper; nylon; oriented polyethylene terephthalate; or a thermoplastic-tape wrap. Such a barrier layer would serve to protect the cable during further processing, and would be applied immediately over the twisted assembly of individual conductors or groups of conductors.
Shield36 - 30 AWG tinned or untinned copper applied as a wrap or braid or a wrap of aluminum faced polyester tape. An uninsulated drain wire may be used. The shield may be over one or more of the insulated conductors or applied between the conductor assembly and the optional covering.
