Wirenco offers a 12/2 MC cable with aluminum armor and copper conductors designed for installation in cable trays and approved raceways. The aluminum interlocking armor provides weight savings—up to 45% lighter than traditional steel—while still delivering robust protection for concealed or exposed installations. It’s suitable for fished or plaster-embedded applications, making it a flexible choice for complex builds.
Southwire 68580055 — 250 ft 12/2 MC Lite Cable
This MC Lite cable uses aluminum armor and soft-drawn copper conductors. It’s designed for use in cable trays and approved raceways, providing a lighter alternative for shorter runs while maintaining the essential protection for power and control circuits.
YDDECW 12/2 MC Cable with Ground — 100 ft
YDDECW’s 12/2 MC cable features a rugged aluminum jacket with solid copper conductors and a grounded design suitable for indoor, outdoor, and underground installations. The product emphasizes high-temperature tolerance and corrosion resistance, making it a viable option for harsh environments and longer-term reliability, even in outdoor or embedded settings.
Armor Lite 12/3 MC Cable — 250 Ft Coil
Although this listing is for 12/3 rather than 12/2, it demonstrates the range of MC cables available from Armor Lite, including copper conductors, aluminum armor, and suitability for installation in cable trays and approved raceways. It’s relevant when planning 12/2 and 12/3 mixed installations in longer projects requiring uniform protection and performance.
Buying Guide
Key purchase considerations help buyers match cable features to project requirements. The following perspectives cover durability, installation environment, grounding, and compliance:
- Armor material and protection: Aluminum armor offers corrosion resistance and lighter weight than steel; assess wear, moisture exposure, and soil or concrete embedding needs.
- Conductor material and size: Copper conductors provide reliable conductivity; ensure gauge and insulation are appropriate for intended current loads and voltage ratings.
- Warranty and compliance: Look for UL-listed products and adherence to standards such as UL 1569 and UL 2556; ROHS compliance can aid environmental considerations.
- Grounding options: Some cables provide a full grounding conductor or dual ground/bond configurations, which can improve reliability in critical facilities (like healthcare environments).
- Environmental suitability: Outdoor, underground, or humid settings benefit from jackets designed for moisture resistance and temperature tolerance (up to 90°C or higher in some models).
- Installation considerations: Availability in long lengths (1000 ft) reduces splicing, while lighter MC cables simplify handling in complex runs; verify compatibility with trays, raceways, plaster embedding, or embedded installations.
- Cost versus durability: Weigh material quality, weight, and protection level; lighter aluminum armor often reduces labor when hauling and pulling, but verify that it meets fire and insulation requirements for your code region.
- Code compliance and local regulations: Check national electrical code (NEC) and local amendments for MC cable in your jurisdiction, especially for healthcare facilities or outdoor installations.
For any large-scale or safety-critical projects, consult a licensed electrician to confirm the right cable type, length, and protection strategy, ensuring compliant and reliable operation across building systems.
