Specification

10 AWG THHN THWN-2 Stranded Copper Building Wire

Allowable Ampacity:

• 40 Amps for General Applications (60°C)

• 40 Amps in Wet Locations (75°C)

• 40 Amps in Dry Locations (90°C)

Description

10 AWG THHN/THWN-2 stranded copper wire is a versatile solution for residential, commercial, and industrial applications. Rated for THHN (thermoplastic high heat-resistant nylon, dry) and THWN-2 (wet) environments, it supports up to 600 volts and operates at temperatures up to 90°C. The flame-retardant PVC jacket resists sunlight, moisture, and chemicals, making it dependable for use in conduit systems, general wiring, and control circuits. It comes in lengths of 25 ft, 50 ft, 100 ft, 250 ft, and 500 ft, as well as by the foot for custom lengths.

What Are the Applications of 10 AWG THHN Wire?

10 AWG THHN wire, with a capacity of up to 40 amps, is suitable for:

• Building Wiring: Lighting circuits, outlets, and electrical connections in homes, commercial buildings, and industrial setups.

• Conduit Systems: Designed for easy pulling through conduits in structured wiring installations.

• Control Systems: Ideal for wiring machinery, HVAC systems, and automation components.

• Residential Appliances: Used for electric water heaters, ovens, and other medium-duty household appliances.

• Subpanels: Suitable for wiring subpanels serving specific areas or outbuildings.

• HVAC Systems: Commonly used in residential or light commercial heating and cooling units.

• Machine Tools and Motors: Wiring tools, equipment, and motor connections in manufacturing or residential setups.

• Feeders and Branch Circuits: Distributing power to outlets, lights, or appliances from service panels.
