"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."
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
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.

No. Standard Aluminum MC cable with open, interlocked metal armor is engineered strictly for dry, indoor, concealed, or exposed installations. It cannot be buried directly in soil or embedded in concrete without a protective, fluid-tight PVC outer jacket (often designated as "Direct Burial MC" or "PVC-Jacketed MC"). For underground runs, you must use an approved underground feeder cable (like MHF or URD) or run standalone conductors through a buried conduit system.
Yes! Wire America carries a full line of PVC-jacketed Direct Burial MC Cable. Standard bare-armor MC cable is rated exclusively for dry indoor or concealed locations. If your project involves underground trenching or wet outdoor locations, check out our 2 AWG 4-Conductor Direct Burial Aluminum MC Cable, which features a sunlight- and moisture-resistant PVC jacket extruded over the armor for direct earth burial without conduit.
Wire America supplies an extensive inventory of 2/4 Aluminum MC cable cut by the foot or on master reels. Most cut-to-length orders are processed and shipped within 24 to 48 hours, delivering directly to your shop or jobsite within 2 to 4 business days once in transit.
We route your order from the regional distribution hub with stock closest to your jobsite to keep transit times and freight costs as low as possible. Expedited shipping options are also available at checkout.

The core structural difference lies in the number of current-carrying insulated conductors inside the assembly. The 2/3 MC Cable profile features three insulated phase wires (typically Black, Red, White) plus a bare ground, making it perfect for single-phase 120/240V subpanels and heavy 240V household loads. The 2/4 profile contains four insulated phase wires (typically Black, White, Red, Blue) plus a bare ground. This fourth conductor is required for three-phase commercial power infrastructure or specialty dual-voltage equipment requiring independent legs.
The allowable ampacity of 2/4 Aluminum MC Cable is 90 Amps, based on the standard 75°C conductor termination threshold outlined in the National Electrical Code (NEC Table 310.16). While the internal XHHW-2 cross-linked polyethylene insulation can safely handle up to 100 Amps under 90°C parameters, the circuit's overall continuous rating must be restricted to 90 Amps to match the maximum temperature limitations of standard mechanical breaker lugs and distribution terminal equipment. The higher 100-Amp threshold is strictly utilized by engineers for ampacity adjustment, correction factors, and environmental derating. Always consult with a local electrician to confirm what size is best for your install.
4/4 Aluminum MC Cable has an approximate physical net weight of 540 lbs per 1,000 feet (lbs/mft). The nominal outside diameter over the external interlocking aluminum armor is 1.23 inches (+/- 5%). Knowing these dimensions allows installers to ensure they select the appropriate trade-size connector fittings and evaluate structural loading capacities for long cable tray pulls.
