MOOKEERF 6/3 MC Cable with Ground – 50FT
The MOOKEERF 6/3 MC Cable with Ground uses THHN/THWN conductors in a compact, steel interlocked armor. With conductor color options in Black, White, and Red and a 6AWG conductor size, the cable delivers solid current capacity. The 8AWG ground wire supports safe fault paths, while a 90°C dry and 75°C wet rating enhances performance in dry or damp locations. The 600V rating aligns with common branch circuit requirements. This cable is UL listed (UL 83, UL1569, UL 2556) and RoHS compliant, reflecting a design suitable for commercial HVAC, lighting, and other branch-circuit applications, where durable protection and weather resistance are needed.
Features emphasize heavy-duty metal armor protection that shields conductors from moisture, corrosion, and physical damage. The combination of steel interlocked armor and fire-resistant insulation helps the cable survive extreme temperatures and harsh environments. This makes the MOOKEERF 6/3 MC Cable a strong choice for installations where environmental exposure or mechanical risk is high, such as factories, warehouses, or outdoor service runs.
Kimbluth 6/3 MC Cable with Ground – 75ft
Kimbluth’s 6/3 MC Cable with Ground is built for rugged outdoor and industrial use. The 75-foot length provides flexibility for long runs, while a 6-gauge stranded copper conductor (seven strands of 1.56 mm) and an 8-gauge ground (seven strands of 1.23 mm) maximize current capacity and safety. The aluminum armor jacket offers strong corrosion resistance and improved heat dissipation in challenging weather conditions. Rated up to 90°C, the cable remains operable in hot environments and aligns with UL 83, UL 1569, and UL 2556 standards, ensuring compliance for commercial installations where durable mechanical protection and reliable electrical performance are critical.
In addition to robust safety features, the cable’s aluminum outer jacket provides flexibility and resistance to humidity and temperature cycling, making it well-suited for outdoor feeders, service entrances, or embedded installations in concrete or soil. The overall assembly is designed to maintain conductivity and integrity over long runs under demanding conditions.
MOOKEERF 6/3 MC Cable with Ground – 25FT
The 25-foot MOOKEERF MC Cable shares the same protective design as its longer counterpart, with Type THHN/THWN conductors and standard 6AWG size for efficient power transmission. Grounding is provided by an 8AWG ground wire, ensuring proper fault clearance. The aluminum armor jacket, combined with UL-listed insulation, supports operation up to 90°C dry, 75°C wet, and a 600V rating. This makes the 25-foot variant suitable for shorter runs in industrial facilities or commercial buildings, where a compact, durable, and code-compliant MC cable is needed for HVAC, lighting, and branch circuits.
With the same emphasis on protection against moisture and physical damage, MOOKEERF products are designed to handle demanding environments, making the cable a practical choice for installations requiring reliable performance in tight spaces or complex layouts.
Kimbluth 6/3 MC Cable with Ground – 50ft
This Kimbluth 6/3 MC Cable provides a versatile 50-foot option for mid-length runs. The reinforced aluminum armor jacket delivers outdoor resilience and protection against corrosive elements, while the 6-gauge copper conductors and 8-gauge ground wire support substantial current capacity. Rated for 90°C and 600V, the cable remains compatible with NEC Article 330 for exposed or concealed use in dry or wet locations. Its rugged construction makes it a solid choice for outdoor feeders, garage-to-house connections, or industrial installations where reliable, code-compliant performance is essential.
Wirenco 6/3 MC Cable with Ground – 25Ft
Wirenco’s MC Cable with Aluminum Armored jacket is designed for multiple applications, including branch and feeder distribution in commercial, industrial, and multi-residential projects. The cable uses stranded copper conductors and a grounded conductor system suitable for 75 Amp THHN ratings, offering a balance of conductivity and protection. The aluminum armor jacket provides corrosion resistance and durability in harsh environments, helping ensure longevity in outdoor or challenging indoor installations. The 25-foot length offers flexibility for short runs or tight spaces where robust protection is needed.
YDDECW 6/3 MC Cable with Ground – 10ft
YDDECW offers a 10-foot 6/3 MC Cable with Ground featuring aluminum armor and solid bare copper conductors. The design emphasizes rugged outdoor durability and UL-based safety standards including UL 83, UL 1569, and UL 2556. The 6-gauge conductors paired with an 8-gauge ground meet typical current and fault-path requirements for compact, short-run installations. The aluminum jacket supports weather resistance and humidity tolerance, making it appropriate for service entrances, outdoor equipment connections, or embedded installations where compact length meets project constraints.
Buying Guide: Key Purchase Considerations
- Conductor material and size: Copper conductors (6 AWG) offer higher current capacity and reliability compared to aluminum-only options, though aluminum jackets can still provide robust protection.
- Armor and jacket protection: A steel interlocked armor or aluminum armor jacket adds moisture, impact, and abrasion resistance, which is crucial for outdoor or industrial environments.
- Temperature and voltage ratings: Look for 90°C dry and 75°C wet ratings and a 600V rating to match typical commercial branch-circuit requirements and NEC standards.
- UL and NEC compliance: Ensure the cable is UL-listed for required standards (UL 83, UL 1569, UL 2556) and compatible with NEC Article 330 for exposed or concealed use in dry/wet locations.
- Length and installation context: Choose lengths that minimize splices while fitting into your space. Shorter runs reduce voltage drop in some scenarios; longer runs require careful routing and support.
- Environmental considerations: For outdoor or damp environments, aluminum jackets with corrosion resistance may provide greater longevity; for indoor dry spaces, steel armor can still be a reliable choice.
- Safety and ground sizing: A proper 8 AWG ground conductor is essential for fault protection and equipment safety in 6/3 configurations.
Overall, the reviewed options emphasize durable armor, copper conductors, and protective jackets suitable for challenging conditions. When selecting a 6/3 MC cable, prioritize the application environment, required current load, and distance to ensure compliance with safety standards and reliable operation over time.
