12/2 Stranded Copper MC Cable W/ Ground is a heavy-duty 600V Metal-Clad (MC) building wire engineered for fast, reliable branch circuit wiring in commercial, industrial, institutional, and multi-residential structures. Constructed with two flexible 12 AWG stranded soft-drawn bare copper conductors, an insulated 12 AWG green ground wire, THHN/THWN-2 insulation, protective binder tape, and an overall aluminum interlocked armor, it delivers exceptional crush resistance and physical protection while drastically reducing labor costs compared to traditional pipe-and-wire installations.
Labor-Saving Metal-Clad Design: Pre-armored assembly eliminates the time-consuming process of pulling individual conductors through conduit, lowering jobsite labor costs and accelerating project timelines.
High-Flex Stranded Copper: Built with Class B stranded bare copper conductors to provide superior flexibility, easier pulls, and smooth terminations inside junction boxes and panel boards.
Dual-Rated THHN/THWN-2 Insulation: High-dielectric PVC insulation with a clear nylon outer skin provides superior heat, flame, moisture, and gasoline/oil resistance rated for 90°C dry applications.
Lightweight Aluminum Interlocked Armor: Tough interlocked aluminum armor (AIA) shields internal conductors from physical damage, crushing, and abrasion while maintaining maximum bendability.
Integrated Green Ground Conductor: Includes a dedicated 12 AWG green THHN/THWN-2 insulated stranded copper ground conductor for complete circuit safety.

12/2 Stranded Copper MC Cable is a 600V metal-clad cable used for 120V/208V branch circuit power, lighting, and receptacle wiring in commercial, industrial, and multi-residential buildings. It features two 12 AWG stranded copper circuit conductors (Black/White) and one 12 AWG green insulated ground enclosed in an aluminum interlocked armor.
Solid MC cable uses single, solid copper wires, which are slightly stiffer to bend. Stranded MC cable utilizes Class B stranded copper wires, making the cable much more flexible, easier to pull through tight wall studs, and easier to bend into junction boxes without work-hardening the copper.
Yes. Because the aluminum interlocked armor provides continuous mechanical protection, MC cable is approved under NEC Article 330 to be installed directly inside walls, exposed across ceilings, or laid in cable trays without pulling through pipe or conduit.
Standard 12/2 MC cable with aluminum interlocked armor is designed for dry indoor applications (rated $90^\circ\text{C}$ Dry). For direct burial or wet outdoor environments, an PVC-jacketed MC cable (PVC over armor) or liquid-tight raceway system is required.
Under NEC Section 240.4(D), 12 AWG copper conductors are generally restricted to a maximum overcurrent protection rating of 20 Amps for standard branch circuits, despite having a higher raw conductor thermal ampacity rating (30A at 90°C).
Aluminum armor is significantly lighter in weight than steel armor—reducing freight costs, easing structural load on cable trays, and making jobsite pulls much faster for field installation crews—while maintaining full impact and crush protection.
