Flexible Conduit Aluminum Metal Clad 12/2 100Ft.
Southwire’s flexible conduit option features a metal clad armor that protects two copper conductors produced in a 12/2 configuration. The 100-foot length supports longer runs with fewer splices, ideal for exterior walls, basements, or protected outdoor installations where mechanical protection is critical. The aluminum armor adds corrosion resistance, while the copper conductors offer reliable conductivity. This cable is suited for environments requiring rigid protection against physical damage while remaining flexible enough for curved routes.
Southwire 68580022 50 ft 12/2 Solid CU MC Lite Cable, Aluminum
This MC Lite cable uses solid copper conductors in a 12/2 configuration with aluminum shielding, offering a lighter alternative for installations where ease of handling matters. At 50 feet, it suits shorter runs in industrial settings, service bays, and indoor-outdoor transitions where robust protection is required but weight and flexibility are priorities. The solid copper construction supports strong electrical performance, while the MC Lite design maintains ease of installation in trays or conduit paths.
Southwire 68580021 Aluminum Cable THHN 12/2 Ga B/W/Green (25ft)
This 12/2 aluminum cable uses THHN/THWN conductors with color-coded insulation for easy identification. The 25-foot length provides flexibility for shorter runs where aluminum armor is advantageous, especially in dry or controlled environments. The black, white, and green insulation helps with circuit identification and grounding practices, making it suitable for installations where code-compliant conductor coloring and durable shielding are required.
Southwire 68580052 50-Foot 12-Gauge 2-Conductor Type MC Cable Aluminum
This 12/2 MC cable from Southwire combines soft drawn copper conductors with a robust aluminum armor. It is designed for installation in cable trays and approved raceways, providing protection against physical damage in industrial facilities, outdoor installations, or long internal runs where trays are used. The combination of copper conductors and aluminum armor supports durability without sacrificing electrical performance over extended lengths.
Armor Lite Type MC Aluminum Armored Cable, 12/3, 600 Volts
Armor Lite offers a 12/3 configuration with aluminum armor, rated for 600 volts and designed for installations in cable trays and approved raceways. While this option includes an extra conductor, it remains compatible with many 12/2 applications where an additional circuit is needed in a protected pathway. The aluminum armor provides rugged protection against impact and moisture, making it suitable for demanding commercial or industrial environments.
100ft 12/2 Metal Clad (MC) Cable with Ground
This 12/2 MC cable from YDDECW features aluminum armor and copper conductors with a ground wire, designed for indoor, outdoor, and underground installations. The rugged jacket and robust shielding make it suitable for harsh environments, including exposed outdoor runs and areas with potential mechanical risk. The included ground conductor supports proper grounding practices in complex wiring projects while maintaining code-compliant protection.
Buying Guide: Key Purchase Considerations
- Conductor material and count: Most 12/2 armored cables use copper conductors for optimal conductivity and durability. Ensure the configuration matches your circuit requirements (12/2 vs 12/3).
- Armor type and rating: Aluminum armor provides lightweight, corrosion-resistant protection, while steel jackets offer higher-impact resistance. Choose based on environmental exposure and physical risk.
- Voltage and temperature ratings: Common ratings include 600V with temperature ratings up to 75°C or 90°C. Confirm compatibility with local codes and intended operating conditions.
- Installation environment: Dry vs wet locations, indoor vs outdoor, and whether cable trays or raceways will be used affect product choice and NEC compliance.
- Length and handling: Longer runs reduce junctions but may require more flexible cables. For tight spaces, MC Lite or lighter constructions can ease installation.
- Codes and listings: Look for UL listings and NEC Article references (e.g., Article 330 for MC cable) to ensure code-compliant installations.
- Grounding considerations: Some 12/2 cables include a ground conductor; verify whether an explicit grounding path is included or if separate grounding is required.
- Cost vs durability: While price matters, prioritize protection, ease of installation, and long-term reliability in demanding environments.
- Application scope: Choose cables designed for cable trays, exposed conduits, or direct burial as appropriate for your project.
