Subj.758 Section 4 Page 4400 Issued:1989-11-16
Style 4400 Multiple-conductor cable using non-integral jacket

Rating60 deg C, Voltage not specified, Horizontal flame.
Conductor30 AWG - 14 AWG solid or stranded round
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.
ShieldOptional - 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.
