SKU CH-6J5K-SVJCV

12 AWG stranded copper THHN wire in gray, 1000 ft coil for 600 V building circuits

  • Product typeWire & Cable
  • THHN 600 V rating supports standard building circuits
  • Stranded 12 AWG copper bends easily through conduit
  • Gray insulation identifies neutral conductors at a glance
  • 1000 ft CoilPAK pays out cleanly without tangling
  • 13 in outside diameter fits tight raceways

Southwire 12 AWG THHN Building Wire

This 12 AWG THHN building wire is designed for general-purpose electrical wiring in residential and commercial settings. The single copper conductor uses a 7-strand construction for flexibility during installation. It is supplied in a 1000-foot CoilPAK for convenient dispensing on the job site.

600 Volt PVC Insulation Rating

The PVC insulation is rated for a maximum of 600 volts, defining the upper limit for circuits where this wire can be safely applied. A nominal outside diameter of 0.13 inches determines the fill capacity when pulling through conduit or raceway. This product is not suited for applications requiring a higher voltage rating or a different insulation type.

Stranded Copper Conductor in CoilPAK

The stranded copper conductor provides the bend radius needed for routing through boxes and around corners without excessive stiffness. Gray insulation allows for standard neutral conductor identification in accordance with common wiring practices. The CoilPAK packaging helps prevent tangling and protects the wire during transport and storage.

Questions about this item

Should I choose the 12 AWG stranded gray coil or a different size for a 600 V circuit?

The 12 AWG stranded gray coil is rated for 600 V and supplied in a 1000 ft CoilPAK, making it suitable for standard branch circuits at that voltage.

What does the 0.13 in outside diameter mean when pulling this wire through conduit?

A nominal 0.13 in outside diameter lets the stranded conductor fit easily through common conduit sizes and reduces pulling friction on long runs.

Is the PVC insulation on this THHN wire compatible with standard 600 V electrical fittings?

Yes, the PVC insulation meets the THHN designation for 600 V applications and works with standard connectors rated for that voltage.
