10ft 10/3 MC Cable with Ground
This 10/3 MC cable uses solid bare copper conductors with aluminum armor for outdoor or underground use. It is sized for 10 AWG conductors with a 600V rating, making it suitable for residential and commercial power distribution in harsh environments. Best for short to mid-length outdoor or buried installations where robust protection is required. A limitation is that shorter runs may complicate ordering if your project needs different lengths.
10/3 MC Cable with Ground 25ft
This 10/3 MC cable comes in a 25-foot length with aluminum armor and three 10 AWG conductors plus a ground. It is well-suited for outdoor or subterranean installations that require additional protective shielding and easier handling on mid-length runs. Choose this if you need a balance of reach and protection in exposed or moist environments. A caution is that longer pull distances may require more planning and assistance to avoid damage during installation.
10/2 MC Cable with Ground – 50FT
This 10/2 MC cable features two 10 AWG conductors plus a ground, armored with aluminum to withstand moisture and physical impact. It’s ideal for longer outdoor runs or basement-to-outdoor transitions in commercial or industrial spaces. Best for projects where more conductor capacity is needed along a single run. A limitation is the reduced interior space compared to some thicker cables, which affects packing in crowded conduits.
MC Cable 10/2 – 50ft (Variant)
This variant provides a 50-foot 10/2 MC cable solution with aluminum armor, suitable for moderate-length installations. It’s a solid choice for wiring that requires dependable protection in wet or outdoor settings. Best for planners who need a straightforward, mid-length option without extra conductors. A note: verify exact conductor count and insulation type for your NEC compliance needs.
10/3 MC Cable with Ground – 100FT
This 100-foot length provides three 10 AWG conductors plus a ground within an aluminum armor sheath. It is designed for longer industrial or commercial power distribution, where robust metal-clad protection is essential. Best for planned runs where junctions are spaced far apart or where trenching must cover extended distances. A limitation is that excessive length may require careful pull planning and additional labor to manage the weight and stiffness of the cable.
Buying Guide: Key Considerations For 10 Gauge MC Cable
Choosing the right MC cable involves balancing protection, conductor configuration, and installation conditions. Consider these practical questions to guide your decision:
- What environment will the cable encounter—indoor, outdoor, or underground? Aluminum armor is designed to protect conductors in moisture-prone or physically demanding locations.
- What length is required? MC cable lengths range from short runs to 100 feet or more. Plan turns, bends, and pulling method to minimize damage.
- Do you need 2 or 3 conductors plus a ground? 10/2 includes two conductors and a ground, while 10/3 includes three conductors and a ground for flexed branching.
- What is the voltage and temperature rating needed for your application? Common ratings include 600V and insulation rated for up to around 90°C dry and 75°C wet environments.
- Are there NEC or local code requirements to meet? Look for UL listings and compliance with NEC Article 330 for exposed or concealed use in dry or wet locations.
- How will the cable be routed? Consider conduit compatibility and the ease of pulling through ducts, trenches, or underground pathways.
Frequently Asked Questions
- What is MC cable used for?
MC cable is used for power distribution in indoor and outdoor settings, offering metal-clad protection for durability and safety in environments where conductors face moisture, abrasion, or physical impact.
- Are 10 AWG conductors suitable for residential 240V circuits?
Yes, 10 AWG conductors are commonly used for 30–50A circuits in residential and light commercial wiring, depending on insulation and code requirements.
- What does “with ground” mean in MC cable?
“With ground” indicates the presence of a dedicated grounding conductor, which improves safety by providing a dedicated return path for fault currents.
- Is aluminum armor necessary for all installations?
Armor offers protection in moisture-prone or physically harsh environments. In dry, protected interiors, armor may be less critical, but local codes may still require it for certain applications.
- How should I size the length of MC cable I need?
Measure the distance between the power source and the load, including any bends and junctions. Select a length that allows for pull length, slack for connections, and future expansion where feasible.
- Do I need to follow NEC Article 330 for MC cables?
Yes, NEC Article 330 covers Type MC cables, including usage guidelines for exposed and concealed locations, wet and dry locations, and installation requirements.
