"Engineered for budget-friendly power distribution and smooth conduit pulls, 4/0 AWG Aluminum XHHW-2 / RW90 Building Wire features compact-stranded AA-8000 aluminum alloy wrapped in a slick, low-friction XLPE jacket. Dual-rated for 600V/1000V systems and approved for wet or dry locations up to 90°C, it delivers superior cost and weight savings over copper for feeder runs, branch circuits, subpanels, and raceway applications."
Slick, Low-Friction XLPE Insulation: Features an advanced "slippery" outer compound that glides through conduit bends effortlessly without pulling lubricant or insulation damage.
AA-8000 Series Compact Aluminum: Built with Class B compact-stranded AA-8000 series aluminum alloy, reducing wire diameter to maximize conduit fill capacity.
Dual Voltage Rated (600V / 1000V): Rated for standard 600V systems as well as higher-voltage 1000V commercial and solar installations.
Cost-Effective Efficiency: Provides reliable conductivity with significant weight savings and lower material costs compared to equivalent copper conductors.
Phase Color Selection: Offered in Black, Red, White, Green, Blue, Orange, Brown, Yellow, Gray, and Purple for instant phase identification (check the dropdown for stock).
Cut-to-Length or Bulk Spools: Order custom lengths cut by the foot to minimize job-site scrap, or purchase bulk spools for high-volume commercial runs.

4/0 Aluminum XHHW-2 is an industry-standard size widely used for:
Per Table 310.16 of the National Electrical Code (NEC):
No, single-conductor XHHW-2 wire cannot be directly buried in soil. While XHHW-2 features rugged cross-linked polyethylene (XLPE) insulation dual-rated for wet underground environments, NEC code requires single-conductor XHHW-2 building wire to be installed inside an approved raceway (such as Schedule 40 or 80 PVC, EMT, or Rigid Metallic Conduit) when placed underground.
Note: If your project requires direct burial without conduit, you will need a cable specifically rated for direct burial, such as USE-2 (Underground Service Entrance) or URD or Mobile Home Feeder (MHF) cable.
Yes. Under NEC 310.12 (the 83% service rule for single-phase dwelling units), 4/0 AWG Aluminum is the standard, code-approved size for 200 Amp main residential services. For general commercial subpanels where 310.12 does not apply, 4/0 AWG Aluminum is rated for 180 Amps at 75°C and can be installed on a 200A breaker under NEC 240.4(B) when the calculated load is 180A or less.
Note: Always consult with a licensed electrician and check your local AHJ building codes to verify specific calculated loads, voltage drop for long runs, and installation requirements for your project.
