 "Engineered for maximum power capacity and tough underground environments, 1/0 3-Conductor Direct Burial Aluminum MC Cable delivers complete feeder protection without the added labor or expense of installing underground conduit.
This heavy-duty cable features three 1/0 AWG compact-stranded aluminum conductors and one #4 AWG aluminum bare ground conductor, protected by an interlocked aluminum armor and covered in a rugged, moisture-proof, UV-resistant PVC outer jacket. Fully approved per NEC Article 330 for direct earth burial, wet locations, and cable tray applications, it is the ultimate cost-effective solution for 120A–125A service distribution, commercial subpanels, detached buildings, and agricultural power runs."
Direct Burial Approved (No Conduit Required): The extruded PVC outer jacket isolates the interlocked aluminum armor from moisture, soil chemicals, and ground rot, allowing you to lay cable directly into open trenches.
3-Conductor High-Amp Layout: Features three insulated 1/0 AWG power conductors plus a bare #4 ground—ideal for 120/240V single-phase 125A subpanel feeds, 3-phase 3-wire delta systems, and heavy equipment runs.
Compact Stranded AA-8000 Aluminum: Built with lightweight AA-8000 series aluminum alloy that reduces overall cable diameter, making it easier to pull through tight bends without sacrificing ampacity.
Sunlight & Flame Resistant: Designed to handle direct exposure to sunlight, wet locations, and indoor/outdoor transitions seamlessly.
Aluminum Interlocked Armor (AIA): Spirally wrapped interlocking metallic armor ensures high crush resistance, physical barrier security, and defense against boring pests, eliminating the labor and material costs of traditional pipe-and-wire conduit installations.
Cross-Linked Polyethylene Insulation: Inner core conductors are insulated with high-dielectric, flame-retardant XHHW-2 / XLPE insulation, certified for stable continuous operation at temperatures up to 90°C in both wet and dry applications.

Compliance Standards: UL 44, UL 1569 (Type MC), NEMA WC70 / 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.
Main Feeders & Service Entrances: Injecting raw power from outdoor utility transformers into high-capacity indoor distribution panels, switchgear arrays, and main disconnect hubs.
Industrial & Heavy Manufacturing Layouts: Routing high-amperage power across industrial environments, paper mills, foundries, mining sites, and petrochemical operations via open indoor or outdoor cable trays.
Direct Burial Site Distribution: Burying underground branch and feeder circuits between commercial facilities, outer maintenance hubs, outbuildings, and municipal wastewater treatment zones.
Hazardous & Assembly Locations: Permitted for use in environments such as arenas, theaters, casino main floors, and industrial hazardous zones (Class I & II, Division 2; Class III, Division 1 & 2) per strict NEC provisions.
75°C Terminal Rating: 120 AMPS — This is the standard engineering design rating. Use this value for final circuit sizing under normal operating conditions, as most commercial breakers, distribution lugs, and equipment terminals are restricted to 75°C terminations.
90°C Terminal Rating: 135 AMPS — This is the maximum capacity rating. Use this value strictly as the baseline calculation factor when adjusting or derating for high ambient temperatures, or when bundling multiple cables closely together in a single trench or tray.
Technical Note: To prevent structural degradation from galvanic corrosion, installers must utilize dual-rated AL7CU or AL9CU mechanical compression lugs or mechanical split-bolts when joining this aluminum cable to copper busbars or breaker terminals. Penetrox or similar antioxidant joint compound must be thoroughly applied to all bare aluminum conductors before final structural torquing. While the PVC jacket isolates the interior armor against direct soil or chemical contact, minimum trench depth profiles must strictly comply with NEC Article 300.5 tables (typically requiring 24 inches of earth cover for direct-buried cables not under concrete paths, or 18 inches beneath standard structural landscapes).
DISCLAIMER: The technical information provided is for general reference only. Large-scale high-voltage feeder systems and underground distribution paths must strictly adhere to the National Electrical Code (NEC), local electrical building enforcement, and relevant safety parameters. Always cross-reference the official product submittal data sheet from the chosen manufacturer prior to finalizing structural configurations or executing structural cuts.

This cable features three 1/0 insulated aluminum phase conductors and one 4 AWG aluminum ground, wrapped in interlocked armor and sealed with a heavy-duty PVC outer jacket. It is engineered for heavy feeder runs, 100A–125A subpanels, commercial service entrances, industrial power distribution, and outdoor equipment feeds that require physical protection against moisture, soil, and impact.
Standard aluminum metal clad (MC) armor cannot be buried without a PVC outer jacket due to galvanic corrosion and soil degradation. While interlocking aluminum armor provides physical defense against rocks and shovels, bare aluminum deteriorates rapidly when in direct contact with wet soil, acidic ground chemistry, or raw concrete. The extruded, sunlight-resistant PVC jacket forms an impermeable waterproof seal that isolates the metal armor, ensuring long-term underground performance.
You must use UL-listed wet-location / direct-burial MC fittings (often called jacketed MC connectors or liquid-tight MC fittings). Standard indoor squeeze connectors cannot be used because they do not form a watertight seal around the outer PVC jacket.
Under National Electrical Code (NEC Table 310.16) guidelines, 1/0 AWG aluminum cable is rated for 120 Amps at standard 75°C terminal ratings (100 Amps at 60°C and 135 Amps at 90°C).
Because 120A is not a standard circuit breaker size, NEC 240.4(B) allows this cable to be protected by a 125 Amp breaker for standard feeder applications. This makes 1/0-1/0-1/0-4 aluminum an ideal, cost-effective choice for 100A to 125A subpanels, residential service entrances, and commercial feeder runs.
**Always consult with a licensed electrician or local building inspector to verify the correct cable size and local code requirements for your specific project.How quickly can I get direct burial mc cable delivered?
Wire America supplies an extensive inventory of Direct Burial 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 ship your order from the regional distribution hub closest to your jobsite to keep transit times and freight costs as low as possible. Expedited shipping options are also available at checkout.

While 1/0 AWG is a heavy feeder wire, this cable uses compact stranded aluminum alloy encased in a flexible interlocking metal spiral under the PVC jacket. It is designed to snake through structural framing and trenches much easier than rigid metal pipe. However, you must respect its minimum bend radius of 10.01 inches (calculated as 7x the 1.43-inch diameter over jacket per NEC standards). You should loop it in smooth, sweeping curves rather than forcing a sharp 90-degree bend, which could bind the internal armor or crimp the conductors.
1/0 3C Direct Burial Aluminum MC Cable has an approximate physical net weight of 764 lbs per 1,000 feet (0.764 lbs/ft). The nominal outside diameter over the protective black PVC outer jacket is 1.43 inches (+/- 5%). Knowing these physical dimensions allows installers to select the correct liquid-tight direct-burial connector fittings, evaluate trench width, and calculate spool handling on the jobsite.
