Southwire 20490912 THHN Building Wire 8 AWG Red Stranded 500 ft

SKU CH-8PF3-RXQS9

THHN building wire with stranded copper conductors, 600 V rating, 40 A capacity, 500 ft length, red jacket

  • TypeWire & Cable
  • THHN rated 600 V for safe indoor wiring
  • 8 AWG copper carries up to 40 A
  • Stranded conductors bend easily through conduit
  • Red insulation simplifies circuit identification
  • 500 ft reel covers long runs without splices

Application & Rating

Southwire 20490912 is 8 AWG THHN building wire rated for 600V AC and 40 amps. The stranded copper conductors and nylon-over-PVC insulation suit conduit installations in residential and commercial projects. Supplied as a 500 ft reel in red for phase identification.

Who It Suits

Electricians and contractors pulling branch circuits or feeder runs in standard conduit systems will find the length and gauge convenient. Installations requiring a different voltage rating, conductor count or colour coding should select an alternative product.

Deciding Specification

The single figure that confirms suitability is the 600V AC voltage rating combined with the 40 amp maximum amperage. If the circuit design calls for a higher voltage class or greater current capacity, this wire will not meet code requirements.

Questions about this item

How can I confirm the 8 AWG THHN wire is performing correctly after installation?

Use a multimeter to verify continuity across the 500 ft run and measure voltage drop under load; the wire is rated for 600V AC and up to 40 amps, so readings should stay within those limits.

What comes with the Southwire 20490912 reel and what must I supply?

The reel includes 500 ft of red 8 AWG stranded copper THHN wire with PVC insulation and nylon jacket; you must provide connectors, conduit, tools and any overcurrent protection devices.

Which version of this THHN building wire should I select for a 40 amp, 600V circuit?

Choose the 8 AWG stranded copper version (model 20490912) in the 500 ft red reel; it matches the 40 amp, 600V AC rating required for that circuit.
