"Engineered for maximum power capacity and tough underground environments, 500 MCM 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 500 MCM compact-stranded aluminum conductors and one 1 AWG aluminum 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 310A-350A commercial service 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.
High-Capacity 500 MCM Layout: Features three 500 MCM phase conductors and one 1 AWG bare ground—ideal for commercial main service entrances, large industrial subpanels, and heavy-amp machinery feeds.
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.

Compliance Standards: UL 44, UL 1569 (Type MC), NEMA WC70 / ICEA S-95-658, IEEE 1202, ASTM B800 & B801, NEC 518.4, NEC 520.5, NEC 645.5, and NEC 300.22.
Main Commercial Feeders & Subpanels: Delivering high-capacity power from utility disconnects to 300A–350A commercial distribution boards and industrial subpanels.
Industrial & Utility Facility Power: Routing heavy 3-phase power across manufacturing facilities, chemical plants, wastewater facilities, and industrial job sites.
Underground Distribution: Running direct-buried main feeders between separate commercial buildings, agricultural complexes, and heavy machinery workshops.
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.

Because of its immense 500 MCM thickness and structural interlocking armor, this cable carries significant Shipping Reel Weight. A standard master reel can easily tip the scales at several thousand pounds. Your drop-off site must have heavy-duty machinery available—such as a large forklift, skid steer, or crane—to safely offload the wooden spool from the freight delivery truck without causing injury or structural damage.
Yes, for large commercial setups, engineers look closely at Soil Thermal Resistivity (Rho). When a massive 500 MCM line carries over 300 Amps of electricity continuous electrical currents, it naturally generates thermal dissipation. If the surrounding trench soil is tightly packed clay or completely dried sand, it can act like an insulating blanket, trapping the heat and reducing the efficiency of the wire. Backfilling the trench with an engineered fluidized thermal mix or loose, damp dirt helps draw the heat away cleanly.
The outer layer features a highly specialized Chemical and Hydrocarbon Resistant PVC compound. It is specifically formulated to withstand typical industrial contaminants such as diesel fuel, motor oils, grease, and common soil acids. However, if your installation environment involves continuous, prolonged immersion in aggressive industrial solvents or raw chemical pools, it should be isolated inside an additional chemical barrier.
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 it is designed for direct burial without any pipe at all, you can absolutely pull it through a conduit if your blueprints require it. However, because of its broad armored diameter, you must calculate for Conduit Jam Ratio. Trying to force a thick, three-conductor armored assembly through an undersized elbow turn can cause the cable to bind and lock up mid-pull. Typically, a minimum of a 4-inch or 5-inch rigid schedule 40 pipe run is utilized to guarantee a smooth pull.
Yes. The thick, seamless PVC jacket combined with appropriate liquid-tight MC termination connectors achieves an exceptional Moisture Protection Ingress Rating. It can easily withstand the high-pressure, hot-water chemical washdowns required in food manufacturing, industrial kitchens, and bottling plants without allowing dampness to breach the internal armor layer or oxidize the core terminations.
It is primarily used as a heavy-duty main feeder line for 300A to 350A commercial service panels, industrial distribution boards, agricultural facilities, solar farms, and heavy equipment. Because it features built-in interlocking aluminum armor under a waterproof PVC jacket, it can be laid directly in open trenches or encased in concrete without buying or gluing separate PVC conduit pipe.
