  • SCOPE

    1 Scope

    1.1 These requirements cover interlocked steel or aluminum armored cables that contain 2, 3, or 4, 14 – 1 AWG insulated circuit conductors with or without grounding conductors and are for use as Type AC Armored Cable in accordance with Article 320 and other applicable parts of the National Electrical Code (NEC), ANSI/NFPA 70.

    1.2 These requirements cover cables for use at potentials of 600 V or less and at temperatures that are not higher than 75°C (167°F) for Type ACTH, or 90°C (194°F) for Types ACHH and ACTHH, depending upon the temperature rating of the insulated conductors used. Cables with aluminum armor are suitable only for use with connectors other than the direct-bearing set-screw type and only in alternating-current circuits.
