"Engineered for budget-friendly power distribution and smooth conduit pulls, 2 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.

#2 AWG Aluminum XHHW-2 is an industry standard size widely used for:
Yes, in most residential applications! Under standard NEC guidelines, #2 AWG Aluminum is rated for 90 Amps at 75°C. However, it is routinely used for 100A main services under NEC 310.12, or installed on a 100A breaker for subpanels using NEC 240.4(B) when the calculated load is 90A or less. Thanks to its huge cost savings over copper, #2 AWG aluminum is the industry-standard choice for feeding subpanels, detached garages, and workshops.
Note: Always consult with a licensed electrician and check your local AHJ building codes to verify calculated loads and specific breaker sizing for your installation
Yes! XHHW-2 is dual-rated for wet and dry locations up to 90°C, making it ideal for underground installations inside an approved raceway (such as Schedule 40/80 PVC conduit). Because it is rated for moisture resistance, underground conduit runs that collect condensation will not degrade the insulation. Note: XHHW-2 single conductors must be installed inside an approved conduit or raceway when placed underground, as they are not rated for direct burial without conduit.
Wire America supplies an extensive inventory of Aluminum XHHW-2 Building Wire from 8 AWG up to 1000 MCM, available in full phase colors and cut by the foot or on master reels. Orders are typically processed and shipped within 1 to 2 business days, delivering directly to your shop or job site within 2 to 4 business days once in transit.
We ship your order from the closest regional distribution hub to your job site to keep transit times and freight costs as low as possible. Expedited shipping options are also available at checkout.

For a standard 120/240V feeder installation requiring three #2 AWG conductors plus a ground, contractors typically use:
Note: Compact-stranded AA-8000 aluminum has a smaller outside diameter (0.361 in) than standard conductors, maximizing conduit fill capacity. Always check NEC Chapter 9, Table 1 for exact 40% fill limits based on your specific conduit type (PVC, EMT, or Rigid).
Per Table 310.16 of the National Electrical Code (NEC):
While both are popular single-conductor building wires used in conduit, key differences include:
