"1 AWG 3 Conductor Direct Burial Aluminum MC (Metal Clad) Cable is a high-efficiency electrical power line designed to deliver continuous feeder and branch circuit power across demanding commercial and light industrial applications. Combining three independent 1 AWG compact stranded AA-8000 series aluminum alloy power conductors with a bare aluminum ground wire, the assembly is shielded within a continuous Aluminum Interlocked Armor (AIA). Finished with an extruded, sunlight-resistant polyvinyl chloride (PVC) outer jacket, this power cable stands up to aggressive soil chemistries, water submersion, and mechanical crushing, satisfying code requirements for direct placement in trenches or raw concrete forms without the expense or installation time of auxiliary conduit networks."
Reliable 100A Branch Feed (1 AWG): Sized perfectly to supply continuous power to 100-Amp distribution panels, large commercial HVAC units, and heavy pump stations.
Three-Phase 3-Wire Core Design: Binds three color-coded conductors into an optimized physical diameter. This profile reduces structural stiffness to deliver clean handling and a tighter minimum bend radius than heavier four-conductor options.
Direct Burial & Concrete Encasement Rated: The heavy-duty, sunlight-resistant outer PVC jacket forms an impermeable barrier against soil chemistry, corrosive moisture, and physical impact, permitting direct trenches or structural concrete encasement.
AA-8000 Aluminum Conductors: Manufactured with premium 8000-series compact stranded aluminum alloy, offering an exceptionally lightweight, cost-effective alternative to copper feeders while maintaining stable electrical performance.
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 degrees 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: 100 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: 115 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.

Yes—feeder applications are its primary purpose! It is engineered specifically to feed 100A to 115A subpanels, commercial distribution panels, detached garages, workshops, and heavy equipment.
Unlike standard 1 AWG building wire (like SER or THHN), which requires pulling through PVC conduit when buried underground, this direct-burial MC cable features an interlocked aluminum armor encased in a waterproof, sunlight-resistant PVC jacket. This allows you to run continuous feeder lines directly through open trenches without the hassle or expense of buying and gluing conduit pipe.
(Note: 1-1-1-4 is common trade shorthand for a 1 AWG 3-conductor cable containing three #1 AWG insulated power conductors and one #4 AWG ground conductor.)
Yes! Unlike standard dry-location MC cable, Direct Burial MC features an overall PVC jacket extruded over the metal armor. Per NEC Article 330, this overall PVC jacket protects the armor from soil corrosion, moisture, and chemical exposure, making it fully approved for direct earth burial, underground duct runs, and wet locations without needing additional conduit.
Under National Electrical Code (NEC Table 310.16) guidelines, 1-1-1-4 aluminum cable is rated for 100 Amps at standard 75°C terminal ratings (85 Amps at 60°C and 115 Amps at 90°C). Because 100A is a standard breaker rating, it is typically protected by a 100 Amp main breaker or subpanel disconnect. It offers a cost-effective, heavy-duty solution for 100A subpanels, workshop feeds, and residential service lines.
**Always consult with a licensed electrician or local building inspector to verify the correct cable size and local code requirements for your specific project.
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 orders 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.

Yes, but you need to check for Voltage Drop. When electricity travels over a long distance, it loses pressure (voltage). While 1 AWG aluminum safely handles 100 Amps at shorter distances, running it 300 feet under full load might cause your lights to flicker or your tools to lose power. For long runs over 150–200 feet, it is highly recommended to have an electrician calculate if you need to step up to an even thicker wire size to compensate for the distance.
Yes. The outer PVC jacket is sunlight-resistant (UV-resistant) and flame-retardant, making it fully approved for exposed outdoor runs, direct sunlight, and installation in cable trays (CT rated).
