"An excellent industrial and commercial choice for multi-phase high-amperage feeder systems, branch circuits, and secondary sub-panel installations. Engineered with a lightweight, interlocking aluminum armor jacket, this pre-protected 4-conductor plus ground assembly eliminates the extensive material and labor expenses of traditional conduit piping. It allows electrical crews to route heavy service lines directly through walls, ceilings, and open cable trays in a fraction of the time."

Why Electricians Choose 1/4 Aluminum MC Cable w/ Ground

In modern commercial and industrial construction, minimizing field labor hours directly dictates project profitability. The 1/4 Aluminum Metal Clad (MC) Cable delivers a pre-armored wiring system that can be uncoiled and installed in up to half the layout time of standard conduit pipe runs. 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 snugly in a rugged interlocking aluminum armor.

  • Labor-Saving Armor: The integrated aluminum interlocked armor serves as its own flexible metallic protective raceway, removing the tedious labor of bending and installing separate EMT or rigid conduit systems.

  • Premium AA-8000 Conductor: Manufactured with compact-stranded 8000-series aluminum alloy to ensure high electrical conductivity, dramatically reduced weight strain during long structural pulls, and excellent flexibility.

  • XHHW-2 Insulation: Individual phase conductors are insulated with cross-linked polyethylene (XLPE), providing elite resistance to heat, moisture, and electrical stress in challenging industrial environments.

  • Maximum Versatility: Code-approved for an exceptionally broad range of heavy-duty installations including commercial distribution panels, large equipment feeders, vertical risers, and environmental air-handling spaces (plenums).

Technical Specifications: 1-1-1-1 Aluminum Metal Clad (MC) w/ Ground

Engineering Overview

  • Conductor Configuration: 4 Insulated Conductors + 1 Bare Ground Wire

  • Conductor Size: 1 AWG

  • Conductor Material: AA-8000 Series Compact Stranded Aluminum Alloy (per ASTM B800 & B801)

  • Conductor Colors: Black, White, Red & Blue

  • Ground Wire Size: 4 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): 100 Amps.

  • Amp Rating (@ 90°C): 115 Amps.

  • Outside Diameter (OD): 1.36 inches

  • Insulation Thickness: 0.055 inches

  • Net Weight: 677 lbs/mft (pounds per 1,000 feet)

  • Minimum Bending Radius: 9.52 inches (Calculated as 7x the OD)

  • Compliance Standards: UL 44, 1569 for Type MC Cable for CT Use, NEMA WC-70/ICEA S-95-658, IEEE 1202 70,000 BTU/HR Vertical Tray Flame Test, ASTM B800 & B801, NEC 518.4, NEC 520.5, NEC 645.5, and NEC 300.22 for environmental air-handling spaces (plenums).

Common 1 AWG 4-Conductor Aluminum MC Cable Applications

  • Multi-Phase Power Distribution: Designed explicitly for 3-phase circuits with a neutral wire (4-wire systems), making it ideal for feeding sub-panels in commercial office buildings, retail grids, and multi-residential complexes.

  • Environmental Air-Handling Plenum Spaces: Fully certified under NEC 300.22, allowing installers to route the cable through dropped ceiling voids and plenum spaces without secondary containment.

  • Hazardous Location Environments: Approved for deployment in specialized industrial environments as permitted under NEC Articles 501, 502, 503, and 504.

  • High-Rise Vertical Risers: Meets standard structural vertical support requirements (per NEC 300.19 and 330.30), making it an excellent choice for main riser shafts running floor-to-floor.


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 Note: Values calculated based on the National Electrical Code (NEC) standards. Because most standard commercial electrical panels, breakers, and terminal lugs feature 75°C termination points, circuits are typically designed based on the conservative 100-Amp standard. The 115-Amp rating at 90°C is utilized for ampacity adjustment and correction factors.

The standard operating ampacity for this cable is 100 Amps when connected to standard 75°C terminal equipment. While its premium XHHW-2 insulation layers are rated up to 115 Amps at 90°C, electrical code requires designing the circuit capacity around the lower thermal limits of the terminal breakers or distribution lugs to ensure system safety.

The core difference is the number of insulated phase wires bundled inside the metal armor. A 3 conductor cable contains three insulated conductors (typically for single-phase layouts: hot, hot, neutral) plus a ground. A 4 conductor cable contains four insulated conductors (typically for 3-phase configurations: hot, hot, hot, neutral) plus a ground. You should select the 1/4 configuration when your commercial gear or power supply panel operates on a 3-phase electrical system.

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, it is highly recommended. While modern AA-8000 series aluminum alloy is incredibly stable and engineered to prevent connection loosening, electrical best practice dictates applying an approved anti-oxidant paste (such as Noalox or Penetrox) onto the stripped 1 AWG aluminum ends before securing them into terminal lugs or breaker connections. This chemical shield prevents ambient oxygen from forming a resistive oxide film, ensuring a permanently safe, cool-running termination.

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. We prioritize shipping MC Cable from the warehouse nearest to your job site to keep transit times minimal. Expedited shipping options are available at checkout for time-sensitive contractor deadlines.
