MOOKEERF 10/2 MC Cable With Ground
Best for moderate indoor and outdoor power runs where 10 AWG conductors with a robust aluminum armor provide strong mechanical protection and adequate current capacity. This cable uses THHN/THWN conductors with a 600V rating, and a RoHS environmental grade, making it suitable for a range of installations that require durability and resistance to oxidation.
- Conductor: 10AWG black/white with 10AWG ground
- Maximum temperature: 90°C dry / 75°C wet
- UL listed: UL 83, UL 1569, UL 2556
- Inner copper: 99.99% OFC; nylon outer insulating surface for performance in high voltage environments
Best for: electricians and contractors performing outdoor or challenging indoor runs where armor strength and reliable conductivity matter. Choose this when you need strong oxidation resistance and a tough outer jacket to resist wear.
Caution: ensure proper bending radius to avoid kinking the aluminum armor, and verify that the equivalent conductor sizing meets local code requirements for the intended load.
XRDS -RF 6 AWG/2 MC Cable With Ground
Better for heavy-duty electrical projects requiring higher current capacity and strong auxiliary protection. The 6 AWG/2 copper conductors deliver greater flexibility and reliability for HVAC feeders, sub-panels, and condenser hookups. The interlocking aluminum armor shields the conductors from physical damage while improving maneuverability during installation.
- Conductor: 6 AWG stranded copper
- Armor: Flexible aluminum interlocking armor
- Safety: Meets UL 83, UL 1569, UL 2556
- Length: 75 ft
Best for: projects where heavy-duty power transmission, resilience to mechanical impact, and easier handling are priorities. Avoid this if your installation calls for thinner conductors or shorter runs beyond its rated length.
Caution: heavier gauge cables require appropriate connectors and support; plan for larger junction boxes and robust clamps to secure the armor.
MOOKEERF 10/2 MC Cable – 50 Ft
This variant emphasizes a solid copper core with aluminum armor, suitable for indoor and outdoor installations where corrosion resistance and reliability are essential. It shares a similar 10 AWG configuration with 600V rating, making it a practical option for feeders and branch circuits that demand durable armor and stable electrical performance.
- Conductor: 10 AWG; 2 current-carrying wires plus ground
- Armor: Aluminum alloy jacket
- Temperature: 90°C dry / 75°C wet
- UL listed
Best for: installations needing durable armor and oxidation resistance in challenging environments. Choose this when you value the combination of copper conductors and aluminum armor for protection against mechanical stress.
Caution: verify that ambient temperatures and conduit/cacing configurations align with the 90°C dry rating, especially in hot locations.
Southwire 12/3 Solid Copper Armorlite MC Cable
Strong for commercial and industrial applications requiring a higher level of conductor and safety features. The 12 AWG solid copper THHN/THWN conductors with an integrated grounding conductor offer clear advantages for branch circuits and power distribution within buildings. The aluminum armor provides robust mechanical protection for exposed runs or cable trays.
- Conductor: 12 AWG copper; THHN/THWN insulation
- Armor: Aluminum interlocking armor
- Voltage: 600V
- Length: 100 ft
Best for: projects where long runs require dependable copper conductors and durable armor in commercial or institutional settings. Avoid if 12 AWG is not sufficient for the intended current or if shorter lengths are needed for tight spaces.
Caution: in areas with high EMI, consider additional shielding or routing strategies to minimize interference with signal cables.
XRDS -RF 6 AWG/2 MC Cable (10 ft)
Best for tight installations where a ready-to-use MC cable with strong aluminum armor is needed for short runs, such as sub-panels or compact equipment connections. The 6 AWG/2 copper conductors provide solid current capacity and flexibility for maneuvering through constrained spaces while maintaining protection against mechanical damage.
- Conductor: 6 AWG stranded copper
- Armor: Aluminum interlocking armor
- Length: 10 ft
- Safety: UL listed standards
Best for: quick, small-footprint installations requiring robust armor and reliable performance. Avoid if a longer run is required or if 6 AWG is more than your current load necessitates.
Buying Guide
- What is MC cable armor and why does it matter? Aluminum armor provides mechanical protection and helps shield internal conductors from damage and EMI, making it suitable for exposed installations and weather-exposed runs.
- Conductor size and current needs: Larger AWG numbers carry less current; confirm your load calculation matches the conductor size (e.g., 6 AWG for heavier loads, 10–12 AWG for typical branch circuits).
- Temperature and environment: Dry vs. wet rating guides where the cable operates. Temperature ratings affect insulation choices and allowed current; verify ratings align with the installation surroundings.
- Voltage rating and code compliance: Most options are rated at 600V and UL listed. Ensure compliance with local electrical codes and box-fill calculations for the specific project.
- Installation considerations: Armor type, length, and bend radii influence ease of installation. Interlocking aluminum armor supports flexible routing and protection against physical damage.
Frequently Asked Questions
- What is MC cable used for?
MC (metal-clad) cable combines conductors with a metal armor for protection in exposed or challenging environments, suitable for feeders, sub-panels, and outdoor runs.
- When should I choose 6 AWG vs 10 AWG MC cable?
Choose 6 AWG for higher current and longer runs where thinner conductors may overheat; choose 10 AWG for standard branch circuits or shorter runs with moderate loads.
- Is aluminum armor enough for outdoor exposure?
Aluminum armor provides mechanical protection and EMI shielding; ensure additional weatherproofing or conduit routing if required by the local code or environment.
- Do all MC cables come with a ground conductor?
Many options include a ground conductor, but verify the product listing and conductor configuration to ensure proper grounding for your installation.
- What installation accessories are typically needed with MC cable?
Connectors, clamps, and appropriate junction boxes are required. Some products include snap-in connectors; others require separate hardware.
- How do I ensure compatibility with my panel or devices?
Match conductor size, insulation type (THHN/THWN), and armor specs to the equipment manufacturer’s requirements and local electrical codes.
