"Engineered for maximum power capacity and tough underground environments, 250 MCM 4-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 four 250 MCM compact-stranded aluminum conductors (three phase legs + one full-size neutral) and one #1 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 200A three-phase 4-wire commercial distribution, industrial subpanels, and utility 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.
4-Conductor Commercial Layout: Features three phase conductors and one dedicated full-sized neutral—ideal for 3-phase 4-wire systems or applications requiring separate insulated neutrals.
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.
Superior Mechanical Armor: The flexible interlocked aluminum armor shields internal wires from soil shifts, sharp rocks, crushed backfill, and physical impacts during installation.
Sunlight & Flame Resistant: Designed to handle direct exposure to sunlight, wet locations, and indoor/outdoor transitions seamlessly.

Industrial Feeder Networks: Supplying 3-phase power to manufacturing equipment, high-horsepower industrial water pumps, and primary distribution switchboards.
Commercial Building Feeder Runs: Routing dedicated 4-wire lines for high-output commercial HVAC chillers, backup generator networks, and large institutional complexes.
Concrete Structural Encasement: Laying primary electrical circuits directly within poured concrete foundations, parking garages, and shipping docks.
Cut to Length: Sold by the foot or in master reels to match your exact trench footprint and minimize scrap.
Fast Processing: Ships directly from closest regional distribution hubs to guarantee minimal transit times and reduced freight costs.
Submittal Assistance: Need cut sheets or manufacturer technical data sheets for engineering approval? Call our sales team directly at 833-268-8644 for immediate jobsite support.
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.

No, you should never hitch this cable to a vehicle to pull it. Heavy 250 MCM cables have a Maximum Pulling Tension limit. Vehicles exert uncontrollable force that can stretch the internal aluminum conductors, thin out the insulation, or snap the interlocking metal armor. Always pull the cable by hand, or use a specialized electrical cable tugger equipped with a safety slip-clutch or tension gauge to avoid hidden internal damage.
Yes, this cable is fully code-approved for crawl spaces, basements, and attics. Even though it is heavily protected for outdoor burial, it transitions beautifully indoors. Its built-in metal armor fulfills the strict safety requirements for exposed indoor wiring, meaning you can secure it directly across floor joists or wall studs without needing to pipe it through separate conduit walls.
Yes, this cable is highly favored for commercial solar fields. Because solar setups require long underground runs from distant panels back to a central inverter or battery station, the cost savings of using thick 250 MCM aluminum alloy over expensive copper are massive. Its direct burial rating and weather resistance make it a standard choice for renewable energy grids.
Wire America ships all of our 250 MCM 4C Direct Burial Aluminum MC Cable directly from our centralized fulfillment centers throughout the United States. We are able to cut to length, process, and ship your order within 1–2 business days and ship straight to your job site, commercial, or residential property. Most standard orders arrive at your doorstep within 2 to 4 business days, with expedited shipping options available at checkout.
This massive, jacketed armor cable is designed for permanent direct earth immersion and concrete encasement. Common applications include:
Under National Electrical Code (NEC Table 310.16) guidelines, 250 MCM aluminum cable is rated for 205 Amps at standard 75°C terminal ratings (170 Amps at 60°C and 230 Amps at 90°C).
Always consult with a licensed electrician or local building inspector to verify the correct cable size and local code requirements for your specific project.
