“The essential standard for 15-amp residential lighting and commercial control circuitsengineered with dual-rated THHN/THWN-2 insulation and a friction-reducing nylon jacket for maximum reliability in 600V applications.”

Why Electricians Choose 14 AWG THHN/THWN-2 Copper

The #14 AWG copper building wire is the primary choice for standard lighting circuits and general-purpose 15-amp outlets. Because it is the thinnest standard building wire, using our stranded version is a massive advantageit is incredibly easy to pull through complex conduit runs and weave through crowded junction boxes.

• Dual Rated (THHN/THWN-2): Engineered for dry locations up to 90C (THHN) and wet locations (THWN-2), providing maximum versatility for indoor and outdoor conduits.

• Tough PVC/Nylon Jacket: The high-heat and moisture-resistant PVC insulation is protected by a tough, friction-reducing Nylon outer sheath, making for easier pulls through tight bends.

• High-Conductivity Copper: Manufactured with soft-annealed stranded copper to provide maximum flexibility and superior electrical conductivity for branch circuits and feeders.

• Oil & Gasoline Resistant: The specialized jacket is designed to resist chemical degradation, making it ideal for industrial environments and service station wiring.

Common 14 AWG THHN/THWN-2 Applications

• Residential Lighting: The standard conductor for 15-amp lighting circuits, ceiling fans, and smoke detector interconnects.

• Commercial Control Wiring: Ideal for HVAC controls, signaling circuits, and remote-control overhead door operators.

• General Purpose Outlets: Used for standard 15-amp receptacles in bedrooms and living areas.

• Conduit Pulls: Specifically engineered to be pulled through EMT, PVC, or flexible conduit in both indoor and outdoor environments.
