Specification

14 AWG THHN THWN-2 Stranded Copper Building Wire

Allowable Ampacity:

• 15 Amps for General Applications (60°C)

• 15 Amps in Wet Locations (75°C)

• 15 Amps in Dry Locations (90°C)

Description

14 AWG THHN/THWN-2 stranded copper wire is rated for THHN (thermoplastic high heat-resistant nylon, dry) and THWN-2 (wet) applications. The "W" indicates that the wire is water-resistant. It supports up to 600 volts and works at temperatures up to 90°C. The PVC jacket is flame-retardant and resistant to sunlight, moisture, and chemicals. This wire is commonly used for lighting, conduit systems, and control wiring. It comes in lengths of 25 ft, 50 ft, 100 ft, 250 ft, and 500 ft.

Applications for 14 AWG THHN Wire

14 AWG THHN wire is ideal for 15-amp circuits in:

• Residential Wiring: Lighting, outlets, and light-duty appliances.

• Commercial Wiring: Small offices and retail spaces.

• Lighting Systems: Standard circuits in homes and businesses.

• Conduit Installations: Fits easily in conduits for wet or dry environments.

• Low-Voltage Circuits: Control wiring, HVAC, and small motors (up to 600 volts).

• Outdoor Use (With Conduit): Suitable for lighting and damp conditions.

• Circuit Breakers and Branch Circuits
