Description

THHN stands for thermoplastic high heat-resistant nylon, a versatile and durable type of building cable. Its THHN/THWN-2 dual rating means it works well in both wet and dry environments, with the "W" indicating water resistance. This wire resists corrosion, dryness, and chemicals, performing reliably at 90°C in wet and dry conditions.

Why Solid Wire?

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

• Simplifies connections to switches, outlets, and breakers.

• Performs best in stable environments with minimal movement.

Common Uses for 14 AWG Solid Wire

• Residential Wiring: Lighting, outlets, and general-purpose circuits.

• Conduits: Straight runs in structured wiring systems.

• Appliances: Stationary devices and small equipment.

• Branch Circuits: Connecting outlets, switches, and light fixtures, supporting up to 15 amps.

• Service Entrances: Suitable for smaller residential setups or code-specific applications.
