MOOKEERF 10/3 MC Cable With Ground — 100 Feet
Overview: Type THHN/THWN conductors with 10 AWG conductors and a 10 AWG ground wire. Rated up to 90°C dry and 75°C wet, with a 600V rating. The product features heavy-duty steel interlocked armor for protection against moisture and physical damage, making it suitable for harsh environments such as HVAC installations in commercial buildings or factories. UL listed (UL 83, UL1569, UL 2556) and NEC-compliant for exposed and concealed use in dry/wet locations.
Applications: Ideal for branch circuits, lighting, and power distribution in commercial or industrial settings. The combination of aluminum armor and fire-resistant insulation supports long service life in challenging conditions. Use where durable armor and reliable performance are priorities, particularly in industrial facilities or outdoor installations.
Southwire 12/3 Solid Copper Armorlite MC Cable — 100 ft
Overview: 12 AWG solid copper THHN/THWN conductors with a green insulated grounding conductor. Rated 600V, featuring durable aluminum armor for mechanical protection and flexibility in exposed or concealed installations, including cable trays and raceways. UL listed and suited for branch, feeder, and service power distribution across various building types.
Applications: Commonly used for commercial and industrial power runs, lighting circuits, and control systems where a balance of conductor capacity and protection is needed. The aluminum armor provides robust protection in high-traffic or outdoor environments, while copper conductors maintain reliable conductivity.
MOOKEERF 14/2 MC Cable With Ground — 100 ft
Overview: 14 AWG conductors, with a ground wire, rated at 90°C dry/75°C wet and 600V. Heavy-duty steel interlocked armor protects conductors from corrosion and damage. UL-listed (UL 83, UL1569, UL 2556) with a nylon-insulated inner surface and premium PVC insulator to resist oxidation and corrosion. This MC cable is designed for high-traffic or industrial settings requiring durable power transmission.
Applications: Suitable for lighting, branch circuits, and small feeders in commercial or industrial environments where compact 14 AWG conductors are adequate, yet armor protection is essential for harsh conditions.
Woods 68579223 100′ 14/2 MC Alum Cable
Overview: 14/2 MC aluminum armor with lighter weight compared to steel. Designed to reduce installation costs and improve handling. UL Classified for various firestop systems, contributing to safer installations in walls and ceilings where fire-rated assemblies are important.
Applications: Appropriate for residential and light commercial runs where ease of installation and weight savings are beneficial, such as in attics, crawlspaces, and above ceilings requiring flexible, armored cable.
Kimbluth 10/2 MC Cable With Ground — 75 ft
Overview: 10 AWG conductors with a ground wire, rated 600V and 90°C dry/wet. Aluminum armor jacket provides outdoor and harsh-environment protection. Meets UL safety standards (UL 83, UL 1569, UL 2556) and offers rugged performance for industrial or outdoor installations. Cable length is 75 ft, suitable for shorter runs or incremental projects.
Applications: Well-suited for outdoor feeders, service entrances, and industrial installations where weather exposure and mechanical protection are requirements, while maintaining a compact form factor for easier installations.
Buying Guide: Key Considerations For 100 Amp MC Cables
- Conductor size and ampacity: Ensure the conductor gauge (e.g., 10 AWG, 12 AWG, 14 AWG) meets the current requirements and enclosure or conduit limitations for the intended load. 100 amp installations often rely on larger gauges such as 10 AWG or 12 AWG depending on distance and voltage drop.
- Armor material: Aluminum armor is common for flexibility and weight savings; steel armor offers maximum abrasion resistance in rugged environments. Consider environmental exposure (moisture, chemicals, soil) when selecting armor.
- Insulation and temperature rating: Look for insulation rated at least 90°C dry; ensure it matches the installation’s ambient temperature and wet locations. NEC guidelines may influence conductor insulation choices.
- Voltage rating: Most MC cables in this category are rated for 600V, suitable for typical branch circuits and feeders in commercial and industrial settings.
- UL and NEC compliance: Verify UL listings and NEC Article compliance (e.g., Article 330 for MC cables) to ensure proper usage in dry, wet, exposed, or concealed locations.
- Installation environment: Outdoor, underground, or conduit-based installations may require different armor, jackets, or glanding solutions for weatherproofing and firestopping.
- Length and handling: Longer runs may increase voltage drop; consider installing in shorter segments or using higher-conductor gauges where appropriate. Weight considerations influence handling during installation, especially for dense runs.
- Code considerations: Local amendments and AHJ (Authority Having Jurisdiction) guidelines may impact allowable installations, tray usage, and supporting hardware. Always confirm that the selected MC cable meets local requirements.
