14GA Stranded THHN Wire, 100ft

THHN14BLK-C

$29.99

| /

14 AWG stranded THHN/THWN-2 building wire — annealed copper with PVC insulation and a nylon jacket, rated 600V and 90°C in wet or dry locations. UL 83 listed.

Use it for: branch circuits pulled through conduit and raceway, control-panel and machine-tool wiring. Stranded conductors pull and bend more easily than solid.

Choose something else if: you are wiring 12V vehicle, trailer or boat circuits — primary GPT wire is the usual choice. For lighting fixtures, see 16GA TFFN Wire.

Sold in 100ft rolls in solid black or black with white stripe.

  • Flame Rating: Flame resistant per UL VW-1 and CSA FT-1•Conduit Fill Advantage: Compact diameter allows additional circuits or larger conductors in conduit without exceeding NEC fill limitations

Residential & Commercial Building Wiring - Install branch circuits, lighting circuits, and general power distribution in homes, offices, retail spaces, and commercial buildings where THHN/THWN-2 rated wire is required for conduit installations meeting NEC requirements.

Conduit & Raceway Systems - Wire electrical circuits through metal conduit, PVC conduit, EMT, rigid conduit, and other recognized raceways in both wet and dry locations where the small diameter allows maximum fill capacity and simplifies wire pulling.

Machine Tool & Control Panel Wiring - Connect motors, controls, and electrical components in industrial machinery, CNC equipment, and control panels where UL 1063 Machine Tool Wire certification ensures compliance with industrial wiring standards.

Appliance & Equipment Wiring - Wire HVAC systems, water heaters, appliances, and electrical equipment where UL 758 Appliance Wiring Material certification and 90°C temperature rating provide reliable performance in demanding environments.

Multi-Circuit Installations - Install multiple circuits in crowded conduit runs where the compact 0.112" outside diameter maximizes conduit fill capacity, allowing more conductors without exceeding NEC fill limitations and reducing installation costs.
