Southwire 50-Foot 12-Gauge MC Cable

This 50-foot MC cable uses soft drawn copper conductors, cabled together and bound with a print-bearing tape. Its aluminum armor provides mechanical protection suitable for cable trays and approved raceways, making it a practical choice for mid-length runs in commercial environments. The copper conductors support reliable current delivery, while the overall assembly offers flexibility for routing through complex installations. Consider this option when you require a balance of conductor quality and armor for indoor or sheltered outdoor paths.
Southwire 250 ft 12/2 Solid CU MC Lite Cable

MC Lite cable with 12/2 solid copper conductors and aluminum armor offers a lighter alternative for longer runs. The 250-foot length accommodates extended feeders or multiple circuit installations with fewer splices. It is suitable for installations in trays and raceways where aluminum armor provides the needed protection. This option is ideal when a longer, straightforward run is required without sacrificing conductor integrity or safety ratings.
Southwire 8 ft Quick Cable Whip, 12/2 MC

This quick-install modular assembly whip reduces the need for locknuts, speeding up panel and equipment connections. Available in 12/2 copper with steel or aluminum armor, it supports rapid deployments in spaces where time matters. Its copper conductors and armor configuration are compatible with standard electrical box fittings and conduit systems, making it a practical choice for configurable or temporary setups requiring dependable power delivery.
Southwire 12/3 Armorlite MC Cable, 100 ft

This 12/3 copper MC cable features premium THHN/THWN insulation, aluminum armor, and a green insulated grounding conductor for enhanced safety in various environments. Rated for 600V, it supports branch, feeder, and service power distribution in commercial, industrial, and multi-residential buildings. The armor provides flexibility and protection for exposed runs as well as concealed installations in trays and raceways.
Woods 100′ 12/2 MC Aluminum Cable

Woods MC Aluminum Cable provides a full 100 feet of 12/2 copper conductors with aluminum armor, suitable for both indoor and outdoor runs. The lighter aluminum armor reduces weight while maintaining durability for cable trays and approved raceways. This option is well-suited for installations prioritizing easier handling and long uninterrupted runs where corrosion resistance and mechanical protection are required.
YDDECW 75ft 12/2 MC Aluminum Cable

This 75-foot MC Aluminum Cable combines rugged outdoor durability with copper conductors for reliable current capacity. The aluminum armor provides resistance to environmental conditions, while UL and safety references support broad installation use in industrial and outdoor settings. Ideal for longer outdoor runs where corrosion resistance and protection are essential.
Armor Lite Type MC Aluminum Armored Cable, 12/3

Armor lite MC Aluminum armed cable with 12/3 configuration supports 600-volt applications and is designed for installations in cable trays and approved raceways. The copper conductors ensure good conductivity and thermal performance, while the aluminum armor provides robust mechanical protection for demanding environments. Suitable for commercial and light industrial wiring projects where flexibility and ease of installation matter.
Buying Guide: Key Purchase Considerations
- Conductor material: Copper conductors offer lower resistance and higher current capacity than aluminum, but weigh more and may cost more. Choose based on required ampacity and installation constraints.
- Armor type: Aluminum armor provides corrosion resistance and flexibility; steel armor offers greater mechanical protection where physical impact is a concern. Match armor to environmental conditions and code requirements.
- Voltage rating and insulation: Most MC cables for general building use are rated at 600V with THHN/THWN insulation. Verify compatibility with signaling, control circuits, and equipment ratings.
- Length and installation ease: Longer lengths reduce splices but may require careful handling and pulling equipment. Quick-install whip options save time in panel and equipment connections.
- Code and standards: Ensure cable meets local electrical codes and UL standards (e.g., UL 83, UL 1569, UL 2556) for outdoor, indoor, and industrial installations.
- Environment: For outdoor or damp locations, select jackets and armor designed to resist moisture, chemicals, and temperature variation. Consider rating for 90°C environments where applicable.
- Applications: Use 12/2 for simple branch circuits and 12/3 for circuits requiring two hot conductors plus a neutral; 12/2 is common for lighting or outlets, while 12/3 supports multi-wire branch circuits or control wiring.
- Installation method: Plan for cable trays, raceways, or direct burial where permitted. Verify that armor compatibility and terminations match fittings and enclosures.
