6/3 Aluminum MC Cable with Bare Ground

"The ultimate commercial and residential branch-circuit solution for heavy appliance and sub-panel feeds. Engineered with an overall interlocking aluminum armor jacket, this pre-armored 3-conductor plus ground assembly removes the need for traditional pipe-and-wire installations, allowing crews to pull 50-Amp circuits directly through walls, ceilings, and open cable trays in a fraction of the time."

Why Electricians Choose 6/3 Aluminum MC Cable

Maximizing labor efficiency is the absolute key to project profitability. The 6/3 Aluminum Metal Clad (MC) Cable provides a completely code-compliant, pre-armored wiring system that can be installed in up to half the time of standard pipe-and-wire runs. Manufactured using premium AA-8000 series aluminum alloy, it features three color-coded XHHW-2 insulated phase conductors and a dedicated bare grounding wire wrapped snugly in a rugged, flexible interlocking aluminum armor—making it the ideal solution for 50-Amp sub-panel feeds, residential EV chargers, and HVAC circuits.

• Labor-Saving Armor: Overall aluminum interlocked armor functions as an integrated protective raceway, removing the labor and material expenses of bending and installing separate conduit systems.

• Premium AA-8000 Conductor: Manufactured with compact-stranded 8000-series aluminum alloy for high electrical conductivity, low weight, and effortless flexibility during pull runs.

• XHHW-2 Insulation: Individual phase conductors are insulated with cross-linked polyethylene (XLPE), providing superior resistance to heat, moisture, and electrical stress in wet or dry locations.

• Maximum Versatility: Code-approved for an exceptionally broad range of installations including commercial branch circuits, HVAC units, equipment feeders, and environmental air-handling spaces (plenums).

Common 6/3 Aluminum MC Applications

• Commercial Branch Circuits: Actively used for power, lighting, control, and signal circuits throughout retail, industrial, and multi-residential structures.

• 50-Amp Sub-Panel Feeders: Ideal for feeding 50A interior distribution sub-panels in detached spaces, additions, or commercial offices.
  
  

• Diverse Environmental Routing: Fully approved for installation inside commercial cable trays, approved raceways, concealed or exposed locations, environmental air-handling spaces (plenums), and vertical structural risers.

• Hazardous Location Environments: Permitted for use in specialized industrial environments as defined and regulated by NEC Articles 501, 502, 503, and 504.

• Heavy Electric Appliances: The industry standard for routing dedicated lines to commercial commercial kitchen equipment, industrial HVAC condensers, and large multi-family dryer circuits.

Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes. Reference NEC Article 330 for specific Metal-Clad installation guidelines.

Ampacity: Values calculated based on the National Electrical Code (NEC) Section 310.16 table. Because most standard commercial electrical panels, breakers, and terminal lugs feature 75°C termination points, circuits should be designed based on the conservative 50-Amp standard. The 55-Amp rating at 90°C is typically utilized for ampacity adjustment and correction factors.
