1000 MCM Aluminum THHN / THWN-2 Building Wire

"The industry standard for lightweight, cost-effective subpanel feeds, commercial equipment power connections, and branch circuit wiring. Engineered for reliable power distribution inside conduit and raceways, this 1000 MCM compact-stranded aluminum wire features triple THHN (dry), THWN-2 (wet), and CSA T90 temperature ratings. Protected by a heat- and moisture-resistant PVC insulation and a slick, abrasion-resistant nylon outer jacket, it pulls smoothly without requiring pulling lubricant."

Key Features & Benefits: 1000 MCM Aluminum THHN / THWN-2 Building Wire

1000 MCM Aluminum THHN/THWN-2/T90 electrical wire delivers dependable 600V power distribution for secondary panels, heavy equipment, and branch circuits at a fraction of the weight and cost of copper conductors. Designed for installation in conduit, cable trays, and approved raceways, it provides a reliable, code-compliant solution for commercial buildings, workshop circuits, and agricultural equipment. Featuring compact-stranded AA-8000 series aluminum alloy conductors, 1000 MCM THHN offers exceptional flexibility and long-term connection reliability. The durable PVC insulation and slick nylon jacket provide high resistance against heat, moisture, gasoline, oil, and mechanical friction during tough conduit pulls.

• Dual 90°C Wet/Dry Rating: Dual-rated as THHN for dry locations up to 90°C and THWN-2 for wet or dry locations up to 90°C (600V maximum).

• AA-8000 Series Aluminum Alloy: Manufactured with high-grade compact-stranded AA-8000 series aluminum for dependable electrical conductivity, reduced weight, and easier handling.

• Cable Tray (CT) Approved: Approved for use in cable trays (1/0 AWG and larger) as well as conduit and raceways.

• Low-Friction Nylon Outer Jacket: Abrasion-, heat-, and moisture-resistant PVC insulation encapsulated in a clear, slick nylon jacket that allows installation without pulling lubricant.

• Cut to Length by the Foot: Order only the exact footage required for your run, eliminating jobsite waste and unused spools.
