4/4 Aluminum MC Cable with Bare Ground

“An excellent commercial and industrial choice for high-capacity, three-phase branch circuits and machinery feeders. Outfitted with four fully insulated, compact-stranded aluminum conductors wrapped in a rugged interlocking aluminum armor jacket, this assembly acts as its own pre-protected raceway, eliminating the labor and material costs of traditional conduit pipe installations.”

Why Electricians Choose 4/4 Aluminum MC Cable

When your layout demands a three-phase layout (three hots and a neutral) at a 65-Amp threshold, the 4/4 Aluminum Metal Clad (MC) Cable provides the perfect equilibrium of power delivery and job site labor savings. Built with premium AA-8000 series aluminum alloy, it bundles four color-coded XHHW-2 insulated phase conductors (Black, Red, Blue, White) and a dedicated bare grounding wire inside a flexible, crush-resistant aluminum armor. It allows installation crews to complete large commercial feeders or complex multi-wire branch circuits in half the time of standard pipe-and-wire setups.

• Conduit-Free Armor Protection: The lightweight, interlocking aluminum armor provides continuous physical protection, bypassing the need to bend and install separate conduit systems.

• Balanced 4-Conductor Three-Phase Design: Perfect for commercial three-phase distribution networks requiring three dedicated hot legs and a full-sized neutral line.

• Premium AA-8000 Series Alloy: Engineered with compact-stranded 8000-series aluminum alloy to ensure minimal weight, effortless bend radius, and stable electrical conductivity over time.

• Premium XHHW-2 Insulation: Cross-linked polyethylene (XLPE) insulation provides superior protection against high temperatures and moisture stress in wet or dry environments.

Common Applications for 4/4 Aluminum MC Cable

• Commercial 3-Phase Power Distribution: The ultimate time-saver for running high-capacity feeders to three-phase electrical panels, high-voltage lighting banks, and commercial multi-wire circuits.

• Industrial Equipment & Motor Feeds: Extensively deployed in factories and workshops to supply 3-phase power loops to industrial machinery, air compressors, and heavy conveyor systems.

• Large HVAC & Chiller Infrastructure: The contractor standard for wiring heavy commercial rooftop air conditioning complexes, multi-stage heat pumps, and refrigeration lines.

• Environmental Plenum Environments: Fully code-approved for open deployment through environmental air-handling plenums, industrial cable trays, and vertical structural risers.

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 65-Amp standard. The 75-Amp rating at 90C is typically utilized for ampacity adjustment and correction factors.
