Type MC Cables – Uses Not Permitted:

Where exposed to destructive corrosive conditions unless the metallic sheath is suitable for the conditions or is protected by material suitable for the conditions

Type MC cables have 2 or more solid or stranded copper conductors in sizes 18 AWG and larger.

The construction of Kaf-Tech's 600 Volt MC cable consists of copper circuit and grounding conductors covered with thermoplastic insulation, an overall polypropylene cable assembly tape and an outer galvanized steel or aluminum interlocked armor.

The armor of interlocked Type MC cable is not an equipment grounding means. Type MC cable will include one or more bare or green grounding conductors.

Type MC cable should be cut with an armored cable rotary cutter. Rotary cutters have many advantages over other methods. Nicking and cutting of the conductors is eliminated and the cuts can be made quickly and safely.

In addition to our standard MC products, Kaf-Tech offers lightweight steel MC TUFF® and other MC cables in a variety of specialty configurations, most featuring the time saving Color-Trak® ID System. These specialty cables are designed for applications such as fire alarm circuits, direct burial or modular office furniture. This section describes the different varieties of MC cable offered by Kaf-Tech.
