Description

THHN stands for Thermoplastic High Heat-Resistant Nylon. Recognized for its versatility and durability, it is one of the most commonly used building cables. The double marking THHN / THWN-2 means it is suitable for wet and dry conditions (the "W" indicates water-safe). This cable is corrosion-resistant, tolerates dryness and chemicals, and is rated for up to 90°C in both wet and dry environments. It operates at up to 600 volts, making it reliable for a range of applications.

Why Solid Wire?

• Provides consistent, low-resistance conductivity for permanent installations.

• Simplifies connections to switches, outlets, and breakers.

• Best suited for stable environments with minimal movement.

Common Uses for 10 AWG Solid Wire

• Residential Appliances: Suitable for medium-duty appliances like electric ovens and water heaters.

• HVAC Systems: Supports smaller residential or light commercial systems.

• Lighting Circuits: Reliable for residential and commercial lighting.

• Conduits: Designed for structured wiring with straight conduit runs.

• Branch Circuits: Distributes power from service panels to outlets, switches, and fixtures.

Construction

Conductor:
Made of annealed soft copper, meeting ASTM B3 and ASTM B8 standards.

Insulation:
PVC insulation with a flame-retardant, sunlight-resistant, lead-free thermoset jacket. The jacket is color-coded as per ICEA Method 4 for easy identification.
