Thhncu-generic thhn14strred500r Thhn 14 Awg Copper Wire 500 Ft

Product Description

The THHNCU-GENERIC thhn14strred500r is a 14 AWG stranded copper THHN building wire rated for 600 volts and 15 amps, supplied on a 500-foot spool with red PVC insulation and a nylon jacket. The 19-strand configuration provides flexibility compared to solid wire, making it easier to pull through conduit runs. The 90 degrees C dry temperature rating meets the demands of standard commercial and residential branch circuit wiring. Licensed electricians use this wire for general-purpose wiring in conduit installations covered by NEC Article 310.

This wire is suited for residential and light commercial electrical installations where THHN-rated conductors are required inside conduit. Common applications include branch circuit wiring for outlets, lighting circuits, and panel feeders. The red insulation color is typically used for phase identification in multi-wire branch circuits or three-phase systems, aiding circuit tracing and code-compliant color coding. The 500-foot spool size is practical for mid-size jobs or service vehicle stock.

Key Features

• 14 AWG copper conductor with 19-strand configuration for improved pull flexibility
• THHN-rated: PVC insulation with nylon jacket, rated for dry conduit installations
• 600-volt rating suitable for standard residential and commercial branch circuits
• 90 degrees C dry temperature rating meets NEC conductor ampacity requirements
• Red insulation for phase identification in multi-wire and three-phase wiring
• 500-foot spool — practical quantity for service work or single-job pulls

Compatibility

Designed for use in conduit installations requiring THHN-rated 14 AWG copper wire per NEC guidelines. Suitable for use in EMT, rigid metal conduit, PVC conduit, and other raceway systems where THHN conductors are permitted.

Installation Notes

Installation of branch circuit wiring must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit or panel before making any connections. THHN wire is rated for dry conduit use only — do not install in wet or damp locations without verifying the applicable wet-location rating. Use appropriate wire-pulling lubricant for longer conduit runs to avoid insulation damage.
