Specification

1 AWG THHN THWN-2 Stranded Copper Building Wire

Allowable Ampacity:

• 110 Amps for General Applications (60°C)

• 130 Amps in Wet Locations (75°C)

• 150 Amps in Dry Locations (90°C)

Description

1 AWG THHN/THWN-2 stranded copper wire is designed for durability and versatility in various applications. With a dual rating for THHN (thermoplastic high heat-resistant nylon, dry) and THWN-2 (wet) conditions, it supports up to 600 volts and operates at temperatures up to 90°C. The flame-retardant PVC jacket resists sunlight, moisture, and chemicals, ensuring reliable performance in demanding environments.

Applications for 1 AWG THHN Wire

1 AWG THHN wire, with a capacity of up to 150 amps, is commonly used for:

• Large Residential Feeders: Supplying power to upscale homes with high electrical demand.

• Commercial Building Feeders: Distributing power in medium to large commercial buildings.

• Industrial Equipment: Powering large machinery that requires substantial current.

• Motor Connections: Providing connections for motors in industrial and commercial setups.

• Service Entrance: Used for service entrance wiring when properly configured and protected.

• Conduit Systems: Easily pulled through conduits for structured wiring.

• Branch Circuits and Feeders: Distributing power from service panels to appliances, subpanels, and fixtures.
