2/4 Aluminum MC Cable W/ Bare Ground

"A commercial and industrial standard for high-capacity, 90-Amp three-phase electrical branch circuits and heavy-duty machinery feeders. Bundling four fully insulated, compact-stranded #2 AWG aluminum phase conductors and a dedicated bare grounding wire inside an overall interlocking aluminum armor sheath, this assembly serves as its own pre-protected raceway—completely bypassing the labor and material expenses of bending and routing independent conduit pipe lines."

Why Electricians Choose 2/4 Aluminum MC Cable

Managing labor hours on the job site dictates project profitability. The 2/4 Aluminum Metal Clad (MC) Cable provides a complete code-compliant, pre-armored wiring system that can be installed in half the time of traditional conduit-enclosed conductors. Built with premium AA-8000 series aluminum alloy, it features four color-coded XHHW-2 insulated phase conductors and a dedicated bare grounding wire wrapped securely in a lightweight interlocking aluminum armor.

• 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 Quadruple 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).

• UL Listings & Standards: UL 44, UL 83, UL 1569 (Type MC for CT Use); NEMA WC-70/ICEA S-95-658; IEEE 1202 Vertical Tray Flame Test; NEC 300.22 (Plenum Spaces), 518.4, 520.5, 645.5

Common 2/4 Aluminum MC Applications

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

• 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.

• Massive Commercial HVAC Equipment: The preferred choice for routing dedicated power to heavy structural rooftop chillers, large-scale ventilation complexes, and centralized cooling grids.

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: 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 30°C (86°F). Because most standard commercial electrical panels, breakers, and terminal lugs feature 75°C termination points, circuits should be designed based on the conservative 90-Amp standard. The 100-Amp rating at 90°C is typically utilized for ampacity adjustment and correction factors.
