Huanchain 12/2 MC Cable with Ground — 250 ft

Product Specification: 12 AWG heavy duty metal cable, 250 ft, 3 solid copper wires (2 current-carrying + 1 ground). Voltage rating: 600V. UL listed. Sturdy aluminum alloy armor provides corrosion resistance and heat dissipation for indoor and outdoor use. Easy to bend, supporting quick installation in harsh weather conditions.
Best for: DIYers and contractors needing long runs with robust protection for both indoor and outdoor wiring, especially where moisture and temperature variation are factors. Caution: ensure correct enclosure and grounding methods to comply with local codes.
Huanchain 12/2 MC Cable with Ground — 100 ft

Product Specification: 12 AWG heavy duty metal cable, 100 ft, 3 solid copper wires (2 current-carrying + 1 ground). 600V rating. UL listed. Aluminum armor delivers corrosion resistance and heat tolerance while remaining easy to bend for versatile installations.
Best for: Projects with limited run length where you need reliable grounding and protective armor. Choose this if you’re balancing budget with installation flexibility. Limitation: shorter length may require splices or additional runs for larger projects.
MOOKEERF 12/2 MC Cable with Ground — 100 ft

Product Specification: 12 AWG conductors with ground, 100 ft, aluminum armor, RoHS environmental grade. UL listed (UL 83, UL1569, UL 2556). Armor shields conductors from moisture and corrosion, supporting safe distribution in harsh environments. NEC-compliant for exposed or concealed uses in dry or wet locations.
Best for: Industrial or commercial spaces requiring durable metal clad protection and NEC compliance. Better for: high-moisture areas or exposed installations where metal armor increases longevity. Caution: verify compatibility with local conduit and protection schemes.
Huanchain 12/2 MC Cable with Ground — 50 ft

Product Specification: 12 AWG, 50 ft, 3 solid copper conductors, 600V rating, UL listed. Aluminum alloy armor provides protection in tough weather conditions and supports easy handling during installation.
Best for: Small to medium projects or renovation jobs with short cable runs. Limitation: longer-term expansion may require additional spools if future needs grow beyond 50 ft increments.
Stock Wire 12/2 MC Cable — 1000 ft

Product Description: 12/2 MC cable with aluminum armor and copper conductors. Designed for branch, feeder, and service power distribution in commercial, industrial, and multi-residential builds. Suitable for concealed or exposed installations and can be fished or embedded in plaster.
Best for: Projects requiring very long runs or bulk purchases for sustained use. Better for: ongoing construction sites or large facilities. Caution: ensure proper handling of long reels to prevent damage or kinks during installation.
Stock Wire HCF MC Cable with Ground — 250 ft

Product Description: Aluminum armored, copper conductors with ground. Green aluminum armor helps with cable identification. Features a full-size green insulated copper grounding conductor and armor/bond wire for redundant or isolated grounding capability.
Best for: Healthcare facilities or spaces requiring precise grounding and easy identification. Limitation: confirm compatibility with local healthcare facility codes and grounding practices.
Buying Guide
What is 12/2 MC Cable? It is a metal-clad (MC) cable with two current-carrying conductors and a ground conductor, shielded by an armor layer (usually aluminum) for protection in wet, dry, and outdoor locations. UL-listed options indicate compliance with safety standards.
Key considerations when choosing MC cable:
- Length requirements: Match the spool length to your project to minimize splices.
- Environment: Outdoor, wet, or corrosive environments benefit from robust armor and copper conductors.
- Conductor material: Copper conductors provide higher conductivity and reliability than alternatives.
- Armor type: Aluminum armor offers protection with lighter weight; steel armor adds more rigidity for harsh settings.
- Voltage rating: Commonly 600V for general-purpose MC cable; confirm local code requirements.
- Code compliance: UL listings and NEC compliance help ensure installation safety and permit approval.
- Grounding strategy: Consider whether a redundant grounding path is desirable or required by code.
Practical decision tips:
- Best for long runs with outdoor exposure: choose 250 ft or longer spools.
- Better for small, indoor-only projects: 50–100 ft options often balance cost and practicality.
- Choose 1000 ft reels when planning bulk installations to reduce frequent replacements.
FAQ
- What is 12/2 MC Cable used for?
Used for branch circuits, feeders, and power distribution in residential, commercial, and industrial settings with metal-clad protection.
- Is aluminum armor strong enough for outdoor use?
Yes, aluminum armor provides corrosion resistance and weather endurance suitable for outdoor and damp environments.
- Do I need a separate ground conductor?
No, but MC cables include a dedicated ground conductor along with two current-carrying conductors, depending on the model.
- What does UL-listed mean for MC cable?
UL-listed indicates the product meets recognized safety and performance standards, aiding compliance and installation confidence.
- Can MC cable be used in plaster or concealed spaces?
Yes, many MC cables are designed for concealed or exposed installations and can be fished or embedded as needed under NEC guidelines.
- What length should I choose?
Pick a length based on your run distance, future expansion plans, and the practicality of minimizing splices.
