"Engineered for budget-friendly power distribution and smooth conduit pulls, 1 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."

Key Features & Benefits: 1 AWG Aluminum XHHW-2 Wire

  • 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.

#1 AWG Aluminum XHHW-2 is widely used for:

  • 100 Amp Subpanels & Feeders: Supplying power to 100 Amp subpanels in commercial buildings, workshops, or residential service equipment.
  • Commercial Machinery & HVAC: Wiring large commercial heat pumps, chiller units, and industrial motors requiring up to 100A continuous terminal ampacity.
  • Feeder Distribution: Running power from main disconnect switches to secondary distribution panels through underground or exposed conduit.

Per Table 310.16 of the National Electrical Code (NEC):

  • 100 Amps at 75°C Terminal Rating: Standard rating when terminating on standard 75°C rated breakers, lugs, and panelboards.
  • 115 Amps at 90°C Conductor Rating: Baseline ampacity used for calculating thermal adjustment factors and ambient temperature derating.

Yes! Rated at 100 Amps at 75°C terminal rating, #1 AWG Aluminum XHHW-2 directly satisfies NEC Table 310.16 standard ampacity requirements for a 100 Amp feeder circuit. It provides a reliable, code-compliant, and cost-effective alternative to copper for residential subpanels and commercial distribution panels.

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.

For a standard feeder installation using three #1 AWG conductors plus an equipment ground wire:

  • 1-1/4 Inch Conduit: Standard size for short to medium runs.
  • 1-1/2 Inch Conduit: Recommended for longer wire pulls or runs containing multiple 90-degree bends to minimize pulling tension.

Note: Compact-stranded AA-8000 aluminum features a reduced outer diameter (0.411 in) to make pulling easier and optimize conduit fill. Always reference NEC Chapter 9, Table 1 for exact fill limits based on your specific conduit material (PVC, EMT, or Rigid).

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.

While both are single-conductor building wires used inside conduit, key differences include:

  • Insulation Material: XHHW-2 utilizes thermoset cross-linked polyethylene (XLPE), which is thicker, more durable, and won't melt or deform under severe overload heat compared to PVC-jacketed THHN.
  • Wet Location Resistance: XHHW-2 maintains higher long-term insulation resistance in wet, high-moisture environments.
  • Pulling Ease: XHHW-2 lacks the stiff nylon outer skin found on THHN, allowing it to glide smoothly around tight conduit sweeps without catching or tearing.

Yes! XHHW-2 features cross-linked polyethylene insulation dual-rated for wet and dry locations up to 90°C. It performs exceptionally well in underground PVC or metal conduit runs where condensation or ground moisture accumulates. Note: XHHW-2 single conductors must be installed inside an approved raceway when placed underground, as they are not rated for direct burial without conduit.
