Woods 68583423 100′ 12/3 MC Alum Cable
Premium copper conductors are soft-drawn THHN/THWN and rated for 90°C in dry environments. The 12 AWG conductors include a green insulated grounding conductor for safety and code compliance. The aluminum interlocking armor provides robust mechanical protection and flexibility for exposed or concealed installations, including cable trays and approved raceways. Suitable for power, lighting, control, and signal circuits in commercial, industrial, institutional, and multi-residential buildings.
Armor Lite MC Aluminum Armored Cable, 12/3
Conduits use soft-drawn copper conductors rated for 600 volts. Armor is aluminum, enhancing flexibility while providing reliable protection in cable trays and approved raceways. This MC cable supports branch circuits and general power distribution in controlled environments, aligning with standard electrical installation practices.
MOOKEERF 12/3 MC Cable with Ground – 50FT
Type THHN/THWN copper conductors in black, white, and red. Ground wire is 12 AWG, with a maximum operating temperature of 90°C dry and 75°C wet. The steel interlocked armor provides heavy-duty protection against moisture, corrosion, and impact. UL listed to multiple standards, this cable is NEC Article 330 compliant for exposed or concealed use in dry or wet locations, ideal for HVAC, lighting, and branch circuits in demanding settings.
MOOKEERF 12/3 MC Cable with Ground – 100FT
Conductor color is Black, White, and Red with 12 AWG copper conductors. The cable carries 600V with a 90°C dry rating and 75°C wet rating. Its heavy-duty steel armor shields against corrosion, moisture, and physical damage, and the UL-listed insulation plus metal sheath withstands extreme temperatures. This NEC Article 330 compliant option is suitable for HVAC, lighting, and branch circuits in harsh environments.
12/3 Metal Clad (MC) Cable with Ground 100ft
Rugged outdoor durability and industrial-grade robustness characterize this 12/3 MC cable. It uses solid bare copper conductors (12 AWG) with aluminum armor. Rated for 90°C and 600V, it delivers high conductivity and current capacity while offering excellent corrosion resistance and heat dissipation. The aluminum armor and weather-ready jacket are designed for indoor, outdoor, and potentially underground installations.
Buying Guide
- Conductor material and rating: Look for copper conductors rated at 90°C dry/75°C wet to ensure safe operation in varying environments. Verify that the insulation and jacket materials meet NEC requirements for your location and installation type.
- Armor type and protection: Aluminum armor offers lighter weight and flexibility, while steel interlocked armor provides maximum protection against mechanical damage. Choose based on exposure to moisture, impact risk, and installation method (tray, conduit, direct burial where allowed).
- Voltage and amperage needs: Most 12/3 MC cables are rated for 600V. Confirm your system’s voltage and potential current draw to select appropriate gauge and insulation.
- Installation environment: For harsh outdoor or industrial settings, prioritize cables with corrosion resistance, heat tolerance, and robust armor. For indoor, low-risk applications, lighter MC cables may suffice.
- Code compliance and listings: Ensure cables are UL-listed and comply with NEC Article 330 or relevant local codes. Check for RoHS or other environmental certifications if required by your project.
- Length and budgeting: Short runs (50–100 ft) are common for MC cable shopping. Longer lengths may reduce joints and improve reliability but may increase upfront cost.
- Spare grounding conductor: Most 12/3 MC cables include a dedicated grounding conductor. Confirm grounding scheme aligns with your panel and branch circuit design.
- Installation practicality: Consider compatibility with cable trays, approved raceways, and the ease of pulling conductors through armor without compromising insulation fidelity.
