This aluminum-armored MC cable is designed for commercial, industrial, and multi-residential construction. It provides protection against moisture, corrosion, and physical damage while delivering reliable power distribution for branch, feeder, and service circuits. The THHN-friendly construction supports broad compatibility with standard conduit systems and installation practices, while the 25-foot length makes it versatile for mid-range runs.
Wirenco 6/3 Metal Clad with Ground, Aluminum Armor (30Ft)
Wirenco’s MC cable features aluminum armor for external protection and a grounded, stranded copper conductor arrangement. Rated for 75 amps, it suits branch circuits and feeders in commercial and multi-residential builds. Its aluminum jacket offers corrosion resistance and flexibility, enabling easier installation in complex pathways and outdoor or indoor environments. The product emphasizes practical NEC-compliant use with standard THHN conductors.
6/3 Metal Clad Cable with Ground (5 ft) Aluminum Armor
This compact 5-foot length cable provides robust aluminum armor and solid copper conductors, designed for indoor/outdoor installations and underground embedded runs. It balances rugged durability with flexibility, supporting reliable performance in challenging weather and temperature conditions. Its UL compatibility and 90°C insulation capacity support demanding electrical layouts in industrial facilities.
6/3 MC Cable with Ground – Aluminum Armor (Summary)
Across the reviewed options, aluminum armor variants offer lighter weight, straightforward installation, and strong protection against environmental hazards. The MOOKEERF option adds a steel interlocked layer for enhanced durability, while others emphasize aluminum jackets for corrosion resistance and flexibility. All selections support 600V operation, appropriate for commercial HVAC, distribution feeders, and branch circuits in demanding settings.
Buying Guide
Key considerations when selecting a 6mm 3 core armoured cable include armor type, conductor material, grounding, temperature rating, and compliance standards. Steel interlocked armor provides maximum physical protection, ideal for exposed outdoor runs or heavy-duty industrial environments. Aluminum armor offers lighter weight and corrosion resistance, suitable for many commercial applications where extreme climates are a factor. Conductor size (6 AWG) influences current capacity; pairing with an appropriately rated ground conductor (often 8 AWG) is essential for safe grounding.
Temperature ratings matter for high-heat installations. Look for cables rated at 90°C dry and 75°C wet to ensure performance in both indoor and outdoor environments. Voltage rating (600V) aligns with typical commercial distribution circuits, but verify branch circuit requirements and connector compatibility. NEC compliance, particularly NEC Article 330 for metal-clad cables, helps ensure code-aligned installation practice. Fire resistance, insulation quality, and sheath durability should be weighed based on location (industrial, commercial, outdoor, underground).
Installation considerations include allowed locations (exposed vs. concealed), bending radius, length flexibility, and protection from mechanical damage. For outdoor or subterranean scenarios, corrosion resistance and UV stability become critical. If future expansion is anticipated, consider available lengths and compatibility with conduit systems and termination hardware. Finally, assess manufacturer documentation for UL listings and installation guidelines to ensure safe, code-compliant operation.
