A heavy-duty 4/0 AWG single-conductor aluminum building wire engineered for underground service entrance feeds, direct burial power distribution, raceways, and branch circuits. Constructed with compact 8000 series aluminum alloy and wrapped in rugged cross-linked polyethylene (XLP) insulation, this 600V triple-rated cable (Direct Burial, Sunlight Resistant & Oil/Gas Resistant) provides extreme resistance to mechanical abrasion, moisture, and chemical exposure in harsh wet or dry environments.
When routing power below grade, into main service panels, or through exterior raceways, long-term environmental protection is essential. 4/0 AWG USE-2 aluminum wire balances cost-effective current-carrying capacity with lightweight, flexible handling. Featuring compact Class B stranding and heavy-duty XLP insulation, it pulls smoothly through conduits and survives direct earth trenching without requiring a protective outer jacket.
Triple-Rated Versatility (RHH/RHW-2/USE-2): Multi-listed for underground service entrance (USE-2), wet-location thermal endurance (RHW-2), and dry-location high-heat applications (RHH).
Direct Burial Certified: Heavy XLP insulation permits direct underground trenching for outdoor lighting, agricultural outbuildings, and subterranean subpanel feeds without conduit.
Compact 8000 Series Aluminum: Formulated with AA-8000 series aluminum alloy for maximum electrical conductivity, improved terminal connection reliability, and lightweight installation compared to copper.
Environmental Resistance: Fully rated as sunlight resistant, oil resistant (PRI/PRII), and gas/oil resistant (GRI/GRII) for industrial and petroleum-exposed environments.

4/0 Aluminum USE-2 / RHW-2 building wire is designed for direct burial power distribution, underground service entrance feeds, and branch circuits running through conduit. It is the workhorse wire size for standard 200A residential utility services, heavy commercial subpanels, agricultural operations, and industrial infrastructure
This wire carries three distinct UL listings for maximum versatility:
Yes, absolutely. The rugged cross-linked polyethylene (XLP/XLPE) insulation is engineered to withstand soil moisture, earth pressure, abrasion, and direct chemical exposure without requiring a conduit sleeve.
Yes. The black XLP insulation compound is explicitly listed as Sunlight Resistant, preventing UV degradation, cracking, or breakdown when exposed to direct sunlight above ground.
No. Per the National Electrical Code and UL standards, single-conductor USE-2 wire is explicitly not rated for use in cable trays. If your installation requires a multi-conductor cable approved for tray installations, raceways, or direct burial overhead feeds, view our 4/0-3C Aluminum Tray Cable (XLP/PVC).
Yes. When terminating 8000 series aluminum wire, always clean the bare conductor strands, apply a listed antioxidant joint compound (de-ox) to prevent oxidation, and tighten lugs to the manufacturer's specified torque rating using AL7CU or AL9CU dual-rated connectors.
Yes. If your electrical panel terminals or equipment disconnects are rated for copper conductors only, or if you need higher current-carrying capacity (260A @ 90°C) in a 4/0 AWG size, view our 4/0 AWG Copper USE-2 / RHW-2 / RHH Building Wire. Copper conductors provide higher conductivity and smaller conduit fill footprints compared to aluminum.
