Stock Wire 12/2 MC Cable With Aluminum Armor
This 12/2 MC cable from Stock Wire combines aluminum armor with copper conductors, designed for branch, feeder, and service power distribution in commercial, industrial, institutional, and multi-residential buildings. It supports power, lighting, control, and signal circuits, and is suitable for concealed or exposed installations. The armor and conductor pairing emphasizes durability and ease of fished or embedded installation in plaster.
Wirenco 12/2 MC Cable with Aluminum Armor
Wirenco offers a 12/2 MC cable with aluminum armor and copper conductors in a 1000-ft cut. It is designed for installation in cable trays and approved raceways, providing lighter weight while maintaining strength through aluminum interlocking armor. This option supports concealed or exposed installations and can be fished or embedded in plaster for flexible framing and building layouts.
Southwire 68580055 250 ft 12/2 MC Aluminum
Southwire’s 12/2 MC Aluminum cable provides a solid option for shorter runs in standard applications and offers a robust conductor setup suitable for MC-Lite configurations. While 250 feet is shorter than 1000 feet, this product is commonly used for indoor runs, cable trays, and approved raceways in settings where longer spools are unnecessary.
Stock Wire 12/2 MC Health Care Facilities (1000 FT)
This Health Care Facilities MC cable variant includes a green insulated copper grounding conductor plus armor/bond wire for redundant or isolated grounding. The aluminum armor remains RoHS compliant with a green armor for easy identification, aligning with medical facility electrical safety standards and long-life performance in demanding environments.
Southwire Armor lite Type MC Aluminum Armored Cable, 12/3
This ArmorLite MC cable provides aluminum armor and copper conductors for a 12/3 configuration, suitable for 600-volt installations in cable trays and approved raceways. Although it is 12/3 rather than 12/2, it complements applications needing additional conductor capacity in similar building environments.
Buying Guide: Key Purchase Considerations
- Length and continuity: For long runs such as 1000 feet, verify that the cable length matches the project requirements and that packaging provides continuous spooling to minimize splices.
- Armor material: Aluminum armor offers lighter weight and corrosion resistance, while steel armor provides maximum mechanical protection. Consider environmental exposure, humidity, and potential physical impact.
- Conductor material: Copper conductors deliver reliable conductivity and are widely compatible with building codes. Ensure insulation and jacket materials suit indoor, outdoor, or hazardous environments.
- Grounding features: Look for models with an integrated grounding conductor or provisions for isolated grounding, especially in healthcare facilities or sensitive electronics installations.
- Code compliance: Select cables that meet UL standards and local electrical codes. For healthcare facilities, ensure MC cables are rated for HCF applications with appropriate grounding.
- Installation environment: Cable trays, approved raceways, concealment in plaster, or direct burial each require specific jacket and armor properties. Confirm compatibility with your installation method.
- Warranty and availability: Longer lengths or specialized variants (like 1000 ft) may have limited stock. Check vendor reliability and replacement policies.
When evaluating 12/2 MC cables for 1000-foot or similar runs, consider armor type, conductor quality, grounding options, and installation method to select a solution that balances durability, ease of install, and code compliance. The five products highlighted above provide representative options across common lengths, environments, and configurations to support informed purchasing decisions.
