"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."
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.
Conductor Configuration: 4 Insulated Conductors + 1 Bare Ground Wire
Conductor Size: 4 AWG
Conductor Material: AA-8000 Series Compact Stranded Aluminum Alloy (per ASTM B800 & B801)
Conductor Colors: Black, White, Red & Blue (Standard 240V 4C System)
Ground Wire Size: 6 AWG (Bare Conductor)
Insulation: High-Heat & Moisture Resistant Cross-Linked Polyethylene (XLPE / Type XHHW-2). A binder tape is wrapped over the insulated conductors' assembly.
Armor: Overall aluminum interlocked armor.
Voltage Rating: 600 Volts.
Temperature Rating: -40°C to 90°C.
Amp Rating (@ 75°C): 65 Amps.
Amp Rating (@ 90°C): 75 Amps.

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

4/4 Aluminum MC (Metal Clad) Cable is a heavy-duty wiring assembly featuring four 4 AWG conductors plus a bare ground, primarily used for three-phase power distribution in commercial and industrial structures. Thanks to its interlocking aluminum armor jacket, it functions as its own pre-armored raceway and can be pulled through framing studs without installing individual pipe conduit. It is commonly used to feed 60-Amp or 70-Amp three-phase sub-panels, connect industrial motors, and wire massive commercial HVAC rooftop equipment.
The allowable ampacity of 4/4 Aluminum MC Cable is 65 Amps @ 75°C and 75 Amps @ 90°C.
*Ampacities are based on NEC Table 310.15(B)(16), and show the allowable Ampacities of three current carrying insulated conductors, in a raceway, cable, or earth based on ambeient temperature of 30°C (86°F).
The core difference is the number of current-carrying conductors. 4/3 MC cable features three insulated wires (typically 2 hots and 1 neutral), which is used for single-phase 240V systems. 4/4 MC cable features four insulated wires (3 hots and 1 neutral), which is specifically required to distribute three-phase power to commercial panels or heavy industrial machinery. Both configurations include an additional bare grounding wire.
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.
4/4 Aluminum MC Cable has an approximate physical net weight of 408 lbs per 1,000 feet (lbs/mft). The nominal outside diameter over the external interlocking aluminum armor is 1.09 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.
Yes. Wire America supplies an extensive inventory of Aluminum MC cable cut by the foot or on master reels. We ship directly from our strategically located regional hubs across the United States, delivering most orders right to your shop or job site within 2 to 4 business days.
