Southwire 12/2 MC Lite Cable, 250 ft
MC-Lite 12/2 solid copper cable with aluminum armor provides a balance of lightweight handling and conductor protection. Ideal for installations where weight savings and easier pulling are priorities, while still meeting code-friendly protection requirements for many residential and commercial applications. The 250 ft length is convenient for longer runs without frequent splicing, though it remains suitable for both conduit and cable tray in appropriate spaces.
Southwire 12/2 MC Cable, 50 ft Aluminum Armor
This MC cable features soft drawn copper conductors tucked inside a binder-wrapped assembly and an aluminum armor run. Suitable for cable trays and approved raceways, it emphasizes easy installation in commercial environments where long runs and robust protection are required. The grounded, two-conductor configuration supports standard branch circuits and general lighting and power distribution.
12/2 Stranded MC Lighting Whip (Generic)
Generic MC lighting whip offers stranded conductors in a 12/2 configuration, with black, white, and green insulation. The flexible whip form makes it well-suited for lighting runs, temporary setups, or where a shorter, easy-to-manage length is desirable. It provides straightforward installation in indoor applications and light commercial uses, with standard 600V ratings implied by MC classifications.
Southwire Armorlite 25-ft 12/2 MC Cable
Armorlite MC cable integrates a robust armor layer designed for embedded or exposed use in commercial and multi-residential settings. The 25 ft length makes it practical for shorter runs in walls or conduit, while the aluminum armor protects conductors from physical damage and moisture intrusion, supporting power, lighting, and control circuits in diverse environments.
Woods 12/2 MC Aluminum Cable, 100 ft
Woods MC aluminum cable offers a longer 100 ft run suitable for larger projects. The lightweight aluminum armor reduces pulling resistance and overall cable weight while providing adequate protection for interior and some exterior installations. The 12/2 configuration supports standard branch circuits and general power distribution in a variety of building types.
Buying Guide
Conductor Material: Copper is the standard for reliability and conductivity, while aluminum armor can reduce weight and cost but may require different handling and termination considerations. For exposed or plaster-in installations, armor-rated MC cables (Armored or Alum Armor) provide extra protection against physical damage and moisture.
Armor Type: Choose between aluminum armor for lighter weight and easier handling, or steel/steel-interlocked armor for higher resistance to damage in harsh environments. Consider whether the installation is indoors, outdoors, or exposed in crawl spaces or ceilings.
Conductor Configuration: 12/2 indicates two conductors plus a ground. Ensure the ground conductor is present, properly bonded, and compatible with your panel and devices. Stranded conductors offer greater flexibility for pulling through conduit and trays, while solid conductors provide stiffness and lower resistance in some cases.
Length and Handling: Longer runs reduce joints but can complicate pulls. Plan for additional length to accommodate bends, turns, and temporary detours. If using conduits or trays, verify clearance and fill ratings to avoid overheating and code issues.
Temperature and Voltage: Most 12/2 MC cables are rated for 600V, with temperature ratings often at 75°C or 90°C depending on insulation and jacket materials. Match the rating to the environment (dry vs. wet locations) and the expected current load.
Code Compliance: Look for UL listings and NEC Article 330 compliance for exposed or concealed use. Check regional amendments and inspector expectations for armored versus non-armored MC cables in different building types.
