Wirenco 6/3 MC Cable — 50 Ft (Aluminum Armored)
Product features include multiple applications for branch, feeder, and service distribution in commercial, industrial, and multi-residential projects. The aluminum jacket provides robust protection, while the THHN ampacity rating is listed at 75 amps, supporting demanding load requirements in protected conduit or exposed runs. This option is well-suited for installers seeking a balance of durability and manageable length for on-site routing.
Wirenco 6/3 MC Cable — 25 Ft (Aluminum Armored)
This shorter variant delivers the same aluminum armor protection and versatility for tight spaces, with a 75-amp THHN rating. It’s ideal for feeders or service runs where a more compact length is advantageous. The cable construction emphasizes durability in industrial and multi-residential construction environments while maintaining flexibility for routing in conduits, trays, or exposed installations.
Stock Wire 6/3 MC Cable — 100 Ft
This 100-foot option provides extended reach for large facilities. It uses an aluminum outer jacket to shield the inner conductors, with stranded copper THHN conductors rated to handle 75 amps. The longer length helps reduce splicing and simplifies routing through large commercial buildings, industrial plants, or multi-residential complexes where longer runs are common.
MOOKEERF 6/3 MC Cable — 50 Ft
MOOKEERF emphasizes heavy-duty metal armor with steel interlocked protection and UL-listed insulation, designed to withstand abrasive environments. The cable features Type THHN/THWN conductors, a 600V voltage rating, and an environmental RoHS-compliant profile. It aligns with NEC Article 330 standards for exposed and concealed locations, making it suitable for HVAC, lighting, and branch circuits in harsh settings.
Kimbluth 6/3 MC Cable — 75 Ft
Kimbluth offers rugged outdoor durability with an all-weather aluminum armor jacket. The conductors are 6-gauge stranded copper, paired with a robust 8-gauge ground wire, delivering strong current capacity and improved heat dissipation. The jacket is designed to resist corrosion, heat, and humidity, and complies with UL 83, UL 1569, and UL 2556 safety standards. This length supports outdoor installations and long indoor runs where extra reach is needed.
YDDECW 75 ft MC Cable — 6/3
YDDECW emphasizes rugged outdoor durability with a heavy-duty 6/3 AWG 600V metal clad design. The cable uses seven-strand 6 AWG copper conductors and seven-strand 8 AWG ground, delivering enhanced current capacity and corrosion resistance. The aluminum alloy jacket contributes excellent weather resistance and flexibility for challenging outdoor installations, making it suitable for underground or exposed installations in harsh environments.
Buying Guide
Key purchase considerations
- Length and routing: Choose a length that minimizes splices and accounts for planned bends, trays, or conduits. Longer runs reduce connections but require careful handling and support.
- Ampacity and voltage rating: Ensure the THHN/THWN conductors’ ampacity aligns with the intended load, typically 75 amps or higher for 6 AWG conductors in MC cables. Verify a 600V rating for typical commercial/industrial use.
- Jacket material: Aluminum armor offers robust protection against moisture, abrasion, and impact. Compare jacket flexibility and corrosion resistance for indoor, outdoor, or underground applications.
- Conductor composition: Copper conductors provide excellent conductivity and heat dissipation. Some options emphasize higher copper content or specific strand counts to improve flexibility and current handling.
- Code compliance: Look for UL listings and NEC Article adherence (e.g., Article 330) to ensure suitability for exposed or concealed locations and for wet/dry environments.
- Environmental conditions: For outdoor or underground use, prioritize jackets with corrosion resistance and high temperature ratings, plus appropriate insulation to withstand ambient conditions.
- Installation considerations: Consider ease of pulling, required pulls through conduits, and available support hardware (beads, clamps, and spacers) to protect conductors during installation.
Common scenarios and comparisons
- Industrial facilities: Long runs and higher loads benefit from longer lengths (e.g., 75 ft) and robust armor to protect conductors in harsh settings.
- Commercial buildings: A balance of durability and flexibility is important; mid-length cables (50 ft) often fit between equipment rooms and distribution panels.
- Outdoor installations: Aluminum armor and weather-resistant jackets are key for outdoor feeders, service entrances, and exposed runs.
- Residential multi-family: Versatile MC cables with solid grounding and rated ampacity fit typical branch and feeder circuits across multiple units.
