6/4 Aluminum MC Cable with Bare Ground

“The preferred industrial and commercial choice for 3-phase branch circuits, feeder systems, and heavy equipment assemblies. Engineered with a lightweight, interlocking aluminum armor jacket, this pre-protected 4-conductor plus ground assembly eliminates the material and labor costs of traditional conduit-and-wire piping. It allows electrical crews to pull high-capacity 3-phase circuits directly through walls, ceilings, and open cable trays in a fraction of the time.

Why Installers Choose 6/4 Aluminum MC Cable

When your project demands a reliable three-phase configuration or an independent neutral circuit, the 6/4 Aluminum Metal Clad (MC) Cable offers unmatched speed and protection. Built with lightweight, high-performance AA-8000 series aluminum alloy, this cable features four color-coded XHHW-2 insulated phase conductors and a dedicated bare grounding wire inside a flexible aluminum interlocked armor. It allows installation crews to complete complex multi-wire branch circuit runs in half the time of traditional pipe-and-wire setups.

• 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).

Technical Note:Technical Note:All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyers 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:Ampacities are based on NEC Table 310.15 (B)(16) (or equivalent local reference tables) and show the allowable ampacities of current-carrying insulated conductors in a raceway, cable, or earth based on an ambient temperature of 30C (86F). Because most standard commercial electrical panels, breakers, and terminal lugs feature 75C termination points, circuits should be designed based on the conservative 50-Amp standard. The 55-Amp rating at 90C is typically utilized for ampacity adjustment and correction factors.
