GENERAL

This category covers fittings for use with metal-clad cable, Type MC, employing (a) interlocking aluminum or steel tape, (b) interlocking aluminum or steel armor ground cable, (c) smooth aluminum tube, or (c) corrugated aluminum or copper tube. The interlocking aluminum or steel armor ground cable is intended for use as a ground and is marked "Armor is equipment grounding path component." This product is intended for installation and use in accordance with the following information and the limitations specified in Metal-clad Cable (PJAZ).

Male threaded fittings provided with or without a locknut and intended for securement to boxes with threaded entries or fittings with internal female threads (e.g., hubs, conduit bodies, couplings) are provided on the smallest unit shipping carton with installation guidance to install into a box with a threaded entry or hub. See PRODUCT/CARTON MARKINGS below for additional information.

Nipples have only been investigated for use with locknuts.

Connector Selection — Connectors are intended to be selected in accordance with the size and type of cable for which they are designated. Bronze connectors are intended for use only with cable employing corrugated copper tube. Aluminum connectors are intended for use only with cable employing corrugated aluminum, interlocking aluminum or smooth aluminum tube, unless marked otherwise on the carton (see PRODUCT/CARTON MARKINGS below).

Use in Concrete — Fittings made of aluminum are not considered suitable for use in concrete or cinder fill unless protected with asphalt paint or the equivalent. Fittings suitable for use in concrete are identified by a marking on the carton.

Grounding — Metal-clad-cable connector and cable combinations in the following table are suitable for grounding for use in circuits over and under 250 V and where installed in accordance with ANSI/NFPA 70, "National Electrical Code."

Cable Connector Type
Interlocking aluminum or steel armor ground cable MCIA
Corrugated aluminum or copper tube MCC
Smooth aluminum tube MCS

Connector types are specifically identified on the manufacturer's product or on the smallest unit container in which the product is packaged.

Dry and Wet Locations — Nonmetallic parts, such as glands or seals, are suitable for use at a temperature of 90°C in dry and wet locations. The fittings are suitable for use in dry or wet locations unless marked otherwise (see PRODUCT/CARTON MARKINGS below).

Use with Armored Cable — Metal-clad-cable connectors also suitable for use with armored cable, Type AC, are so marked on the device or carton. Certified armored cable, Type AC, is covered under Armored Cable Connectors, Type AC (AWSX).

Use with Flexible Metal Conduit — Metal-clad-cable connectors also suitable for use with flexible metal conduit, Types FMC, RWFMC and XRWFMC, are so marked on the device or carton. Certified flexible metal conduit connectors, Types FMC, RWFMC and XRWFMC, are covered under Conduit Fittings (DWTT).

Reusability — Connectors have not been investigated for reusability. Reusability should be determined by the installer and the Authority Having Jurisdiction.

See INSTALLATION REQUIREMENTS, Enclosure Types under Electrical Equipment for Use in Ordinary Locations (AALZ) for further information.

PRODUCT/CARTON MARKINGS

Metal-clad-cable fittings or the smallest unit shipping cartons are marked with (1) the range of cable diameters and the type of cable sheath (corrugated, interlocking or smooth), (2) the material of the sheath (aluminum, copper or steel) for which they have been investigated, (3) "Concrete-tight" if suitable for use in poured concrete, (4) "For Type AC Cable" (or equivalent wording) if suitable for that use, and (5) "For FE or AL (unless for use with both) FMC, RWFMC or XRWFMC" (or equivalent wording). See the following table for additional carton markings. Metal-clad-cable fittings suitable for use only in dry locations are marked "Dry Locations" on the device and smallest unit carton.

Type of Metal-clad Cable Abbreviation
Metal-clad interlocking armor cable MCI
Metal-clad interlocking armor ground cable MCI-A
Metal-clad continuous smooth sheath armor cable MCS
Metal-clad continuous corrugated sheath armor cable MCC
Metal-clad continuous corrugated sheath armor cable, flat FLAT

Male fittings not provided with a locknut, intended for securement to a threaded hub, are marked on the smallest unit shipping carton, "For securement to a threaded hub only," or the equivalent.

Male fittings provided with a locknut, also intended for securement to boxes with threaded entries, hubs or fittings with internal female threads (e.g., conduit bodies, couplings), are marked on the smallest unit shipping carton, "For securement to a threaded hub," or the equivalent.

Fittings suitable for use in poured concrete or where exposed to rain are so indicated on the device or carton. The terms "Rain-Tight," "Wet Location" or the equivalent on the carton, indicates suitability for use where directly exposed to rain. The term "Concrete-Tight" or equivalent on the carton indicates suitability for use in poured concrete.
