Southwire 68580055 250 ft 12/2 Solid CU MC Lite Cable, Aluminum
Best for long runs in residential or light commercial projects. This MC Lite cable uses aluminum armor and solid copper conductors for efficient power distribution. The long 250-foot length supports extended installations with fewer splices, reducing connection points and potential failure points.
- Best for: Professional installers planning long cable runs.
- Why selected: Combines durable aluminum armor with reliable copper conductors for steady current flow.
- Limitation: Aluminum armor may be less impact-resistant than heavy-duty steel in extreme environments.
Southwire 68580052 50-Foot 12-Gauge 2-Conductor Type MC Cable Aluminum
Ideal for shorter runs or retrofit projects where flexibility matters. Conductors are soft-drawn copper, and the assembly is bound with a printed binder tape. Suitable for installations in cable trays and approved raceways, making it a practical option for interior wiring jobs.
- Best for: Short to medium runs in indoor or controlled environments.
- Why selected: Easy to pull and handle thanks to copper conductors and binder-tape protection.
- Limitation: Shorter reel length means more joints on larger projects.
12/2 MC Cable with Ground – 50FT Pure Copper, Aluminum Armor
Strong choice for commercial or industrial settings with potential exposure to moisture or physical stress. This cable uses heavy-duty steel interlocked armor and UL-listed fire-resistant insulation. It is designed for NEC-compliant, exposed or concealed use in dry or wet locations up to 90°C dry / 75°C wet.
- Best for: Environments needing rugged protection and NEC compliance.
- Why selected: Multi-layer protection resists moisture, corrosion, and mechanical damage.
- Limitation: Heavier armor can be stiffer to work with in tight spaces.
12/2 MC Cable with Ground 100 ft – Aluminum Armor, UL Listed
Designed for robust indoor and outdoor installations, including underground use. It uses solid copper conductors for high current capacity and corrosion resistance, with an aluminum armor jacket that protects against moisture and physical damage. Fully UL listed for reliability in industrial settings.
- Best for: Outdoor or underground installations requiring corrosion resistance and UL compliance.
- Why selected: Combines copper conductivity with corrosion-resistant armor for versatile use.
- Limitation: Heavier and less flexible than non-armored cables in tight spaces.
Buying Guide
What is MC Cable 12/2 and when should you use it?
MC (Metal Clad) Cable 12/2 with ground contains two current-carrying conductors and a grounding conductor, all with a metallic armor jacket. It is suitable for indoor and outdoor installations, including exposed or concealed layouts, and supports higher protection in demanding environments than non-armored wires.
Armor material: aluminum vs. steel interlocked
Aluminum armor is lighter and easier to install, good for most indoor and outdoor projects. Steel interlocked armor offers superior protection against crushing and physical damage, making it preferable in construction sites or environments with heavy wear. Consider the trade-off between weight, flexibility, and protection when choosing.
Conductor material: copper vs. aluminum
Copper conductors provide high conductivity and durability, but aluminum armor remains common for lighter, cost-conscious installations. For critical power runs and longer distances, copper conductors are often favored for efficiency and heat performance.
Voltage rating and temperature ratings
Most 12/2 MC cables rated at 600V with dry/wet temperature ratings of 90°C/75°C are suitable for both indoor and outdoor usage. Always verify local electrical codes and NEC Article 330 compliance for exposed or concealed placements.
Length, flexibility, and installability
Longer reels reduce splices but can be harder to handle in tight spaces. Shorter lengths offer more control but may require more terminations. Assess the project scope, location, and installer experience when selecting length and armor type.
Standards and safety
Look for UL-listed MC cables and products that comply with NEC guidelines. Certification ensures compliance with safety and reliability standards across commercial, industrial, and residential projects.
Summary of considerations
- Best for long exterior runs: MC Lite aluminum armor options with copper conductors.
- Best for corrosion-prone areas: Aluminum armor with robust shielding and UL listing.
- Best for harsh environments: Steel interlocked armor for heavy-duty protection.
- Best for short indoor runs: Copper conductors with flexible, binder-tape protection.
FAQ
- What does 12/2 MC cable mean?
Answer: It indicates two current-carrying conductors plus a ground conductor, using metal-clad armor for protection. - Is copper or aluminum better for MC cable?
Answer: Copper conductors offer higher conductivity and durability, whereas aluminum armor reduces weight and cost. - Can MC cable be used outdoors?
Answer: Yes, when rated for outdoor use and with appropriate armor and insulation, complying with local codes. - What is UL-listed MC cable?
Answer: It has been evaluated for safety and compliance under UL standards, suitable for industrial, commercial, and residential applications. - Why choose a longer reel?
