Southwires MC-PCS Duo is suitable for use as circuits for branch power distribution in commercial, industrial, institutional and multi-residential buildings as well as power, lighting, control and signal circuits. It works with LED lighting with 0-10V dimming. This cable is constructed with 12 AWG CU Type THHN/THWN power and ground conductors along with a control conductor assembly composed of a 30 mil PVC jacket covering two 16 AWG CU Type TFN control conductors. The phase conductors, ground and control conductor assembly are cabled together and a binder tape bearing the print legend is wrapped around the assembly. Aluminum interlocking armor is applied over the taped assembly. Yellow stripe/blocks are printed on the outside of the armor and the print legend is applied in black print on every 4th yellow stripe/block.

Armored building cable is a collection of plastic-coated insulated wire bundled together and protected by a corrugated metal jacket (called a sheath or cord) that serves as a conduit and provides grounding. Also known as BX cable or metal-clad (MC) cable, armored cable prevents accidental penetration better than NM-B building cable, but it is heavier and harder to handle, rip back, and cut. It is often used in applications where cable will be exposed to mechanical or environmental damage under normal operating conditions, such as power circuits in industrial plants and commercial buildings.Building wire and cable carry electrical current from a power source to a device in a building, such as an outlet or light fixture. Building wire is typically run through conduit, cable trays, or raceways. Building cable consists of multiple strands of wire bundled inside a thermoplastic or metal sheath. Building wire and cable are typically used to run new circuits or extend old circuits inside walls and ceilings in commercial, industrial, and residential properties.
