Southwire 20489112 Thhn Wire 8 Awg Stranded White 500 Ft

Product Description

The SOUTHWIRE 20489112 is a 500-foot roll of 8 AWG stranded THHN building wire with white insulation. It is rated for 600 volts and up to 90 degrees C, making it suitable for general-purpose power, lighting, and control wiring in commercial and residential construction. The conductor is stranded copper, covered with flame-retardant PVC insulation and a nylon jacket. That nylon jacket provides resistance to oil, gasoline, chemicals, and abrasion, extending service life in demanding conduit environments. Electricians reach for this wire on new construction, panel feeds, branch circuits, and equipment connections.

This wire is designed for use in conduit and raceways. It fits standard dry, damp, and wet location conduit runs where THHN-rated wire is specified. The stranded construction makes pulling through conduit easier than solid wire of the same gauge, which is especially useful on longer runs or installations with multiple bends. The 500-foot roll length suits full-floor wiring jobs, service entrance feeds, and other high-volume installations where shorter cuts would require splicing.

Key Features

• 600-volt rating for branch circuit and feeder applications
• 90 degrees C temperature rating for high-heat conduit environments
• Stranded copper conductor for flexible, easy-pull conduit installation
• Flame-retardant PVC insulation with nylon jacket for chemical and abrasion resistance
• UL listed for code-compliant installations
• 500-foot roll reduces splicing on large jobs

Compatibility

Designed for use in conduit and raceway systems where THHN or THWN-rated 8 AWG building wire is specified per NEC requirements for power, lighting, and control circuits.

Installation Notes

Installation should 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. Use a properly sized conduit fill calculation to confirm the raceway accommodates the wire count and gauge. Avoid kinking stranded wire during pulls; use wire-pulling lubricant on longer runs to reduce jacket wear.
