SOUTHWIRE COMPANY

SOUTHWIRE COMPANY 11592301 THHN 12 AWG Yellow Solid 500 ft

SKU CH-9XHV-QT89D

12 AWG solid copper THHN building wire on a 500 ft spool, yellow PVC insulation rated 600 V with a 0.12 in. outside diameter

  • TypeWire & Cable
  • Solid 12 AWG conductor simplifies installation
  • THHN PVC insulation rated for 600 V applications
  • Yellow jacket provides clear circuit identification
  • 500 ft spool reduces splice points on long runs
  • Copper conductor ensures reliable current carrying capacity

12 AWG THHN Building Wire

This 12 AWG THHN building wire uses a single solid copper conductor rated for 600 V. The PVC insulation and yellow colour coding suit standard residential and light-commercial branch circuits. Electricians and DIY installers can pull it through conduit for new runs or rewiring jobs.

Solid Conductor on 500 ft Spool

The solid conductor holds its shape during long pulls and terminates cleanly under screw terminals. A 500 ft spool provides continuous length for multiple circuits without splices. Yellow insulation identifies the phase at a glance in multi-wire bundles.

PVC Insulation Rated 600 V

The PVC jacket resists abrasion and moisture in dry or damp locations up to 600 V. Nominal outside diameter of .12 in fits standard conduit fill calculations. Solid copper keeps voltage drop low on typical branch-circuit loads.

Questions about this item

What voltage does the 12 AWG THHN wire handle?

The wire is rated for 600 V, which is the standard ceiling for THHN building wire in residential and commercial branch circuits.

What conduit size fits the 0.12 in outside diameter?

A 0.12 in nominal OD typically fits in 1/2 in EMT or PVC conduit; always verify fill tables for the exact number of conductors you plan to pull.

How do you strip the solid PVC insulation without nicking the copper?

Use a calibrated stripper set for 12 AWG solid, score once, then twist off the slug; the common mistake is using dull side-cutters that crush and weaken the single strand.
