Woods 68579223 100′ 14/2 MC Alum Cable
Woods 68579223 MC aluminum armor cable is designed to reduce installation costs by up to 50% compared with traditional pipe-and-wire methods. The aluminum armor is notably lighter—up to 45% lighter than steel MC cable—facilitating easier handling on job sites. This 14/2 configuration is suitable where two conductors plus a ground are adequate for the circuit. The product is UL classified for through-penetration firestop systems, enhancing fire resistance in walls and floors. Its versatility makes it a practical choice for commercial and residential retrofit projects that require multi-circuit distribution in limited spaces.
Woods 68580023 100′ 12/2 MC Alum Cable White
This 12/2 MC aluminum armored cable is crafted for efficiency and performance in electrical installations. Made in the U.S.A., it promises notable installation cost reductions and a lighter profile than traditional steel MC cable. The aluminum armor provides corrosion resistance and durability for commercial and residential projects where multi-conductor circuits are required. The cable’s compatibility with hollow walls and plastered surfaces makes it a solid option for renovations or new builds that emphasize speed and ease of installation.
VN Infinite quality 12/2 MC Alum Cable
The VN Infinite quality 12/2 MC aluminum cable emphasizes cost-effective installation by reducing labor and materials costs by up to 50% relative to traditional pipe-and-wire methods. The lightweight aluminum armor is up to 45% lighter than steel MC cable, easing handling and speeding up runs in large commercial or multi-residential developments. UL classification for 1, 2, and 3-hour Through Penetration Firestop Systems provides enhanced fire safety, making it suitable for areas requiring stringent fire ratings. This option suits projects prioritizing efficiency without compromising strength or compliance.
Woods Southwire 68583421 25-Foot 12-Gauge 3-Conductor MC Cable
This 12/3 MC cable from Woods and Southwire combines robust aluminum armor with a conductor count suitable for more complex branch, feeder, or service circuits in commercial, industrial, and multi-residential buildings. Its robust construction supports power, lighting, control, and signal circuits embedded in plaster or finished surfaces. The 25-foot length is convenient for shorter runs or routing in tight spaces, while the aluminum armor helps reduce overall weight and ease installation in retrofit projects where multiple circuits are required in a single run.
Southwire 14/2 Type 50-Feet 14-Gauge MC
This 14/2 MC cable offers a balance of economy and performance for smaller multi-circuit projects. Its aluminum armor provides durability and protection against impact and physical damage, while the lightweight design supports easier installation in confined spaces. The inclusion of a green insulated ground wire aligns with standard practice for safer grounding. Firestop compatibility remains a key benefit for use in walls and floors that require rated penetrations, making it a practical option for renovations and new builds with moderate circuit requirements.
Buying Guide
Key purchase considerations for multi-circuit MC cable include conductor count and gauge, armor material, firestop classifications, and installation environment. For larger commercial or industrial installations, higher conductor counts (such as 12/3 or 14/2 with ground) can simplify routing and reduce the need for additional conduits. Aluminum armor offers weight savings and corrosion resistance, improving handling on job sites and longevity in damp or challenging environments.
Firestop compatibility is a critical factor in finished or plastered spaces. Look for UL classifications indicating 1, 2, or 3-hour Through Penetration Firestop System support if fire ratings are required by local codes. Consider the ease of pulling and bending MC cable during rough-in work; lighter cables typically reduce manpower and labor costs, especially in retrofit scenarios.
The manufacturing origin and quality certifications (such as Made in USA or UL classifications) can influence procurement decisions and warranty coverage. When selecting a product, align the conductor configuration with the actual circuit design, ensuring you have adequate conductors for future expansion while maintaining comply-with-code practices. Finally, review the length options and the availability of matching accessories or termination hardware to ensure a smooth installation workflow.
