100ft 12/3 Metal Clad (MC) Cable with Ground
Features rugged outdoor durability with a 12/3 configuration and ground conductor. This heavy-duty 600V metal-clad cable uses an insulated design and aluminum armor jacket to withstand harsh weather, heat, and humidity up to 90°C. The conductors are 12-gauge bare copper (2.05 mm diameter) to deliver strong conductivity and current capacity. The aluminum alloy jacket resists corrosion, accommodating outdoor or embedded installations in varied environments.
Key considerations
- All-weather aluminum jacket balances flexibility and protection.
- Solid copper conductors enhance current capacity and longevity.
- Rated for 600V and up to 90°C dry/75°C wet conditions.

The cable is UL-listed to meet safety standards (UL 83, UL 1569, UL 2556) and supports exposed or concealed installations in dry and wet locations. The aluminum armor jacket provides all-weather protection and improved durability in industrial environments, making it suitable for service, feeder, and branch circuits in demanding settings.
Key considerations
- UL safety certifications support reliable commercial use.
- Aluminum armor offers protection against physical impact and moisture.
- Compliant with NEC Article 330 for versatile installations.
Armor lite Type Mc Aluminum Armored Cable, 12/3, 600 Volts, 250 Ft. Coil
This 12/3 MC cable features soft-drawn copper conductors rated for 600 volts and is approved for installation in cable trays and approved raceways. The aluminum armor provides mechanical protection for longer runs and challenging environments, making it a practical choice for industrial electrical systems requiring reliable performance over extended cable lengths.
Key considerations
- 250 ft coil offers long runs with fewer splices.
- Soft-drawn copper enhances flexibility and ease of pulling.
- Armor is compatible with raceways and cable trays.
Buying Guide: Key Purchase Considerations
- Conductor material and gauge: 12 AWG copper conductors provide adequate current capacity for small-to-medium loads; ensure the gauge meets your circuit requirements.
- Armor type and protection: Aluminum armor is lightweight and corrosion-resistant, while steel interlocked armor offers higher physical protection in harsh environments. Choose based on exposure, weather, and installation method.
- Temperature and voltage ratings: Look for 90°C dry / 75°C wet ratings where applicable, and a voltage rating of 600V for most commercial applications.
- UL and NEC compliance: Verify listings (UL 83, UL 1569, UL 2556) and Article 330 compliance to ensure suitability for exposed/concealed dry or wet locations.
- Outdoor vs indoor suitability: For outdoor runs, ensure the jacket and armor resist moisture, UV exposure, and temperature extremes; indoor uses may have less stringent protection needs.
- Length and installation logistics: 100 ft runs reduce the number of terminations and splices, but consider future expansion and available conduit or trays.
- Cost vs durability: While aluminum armor is lighter and often cheaper than steel, evaluate the balance between upfront cost and long-term protection in the installation environment.
