12 AWG THHN Stranded Wire

This black building wire uses a 12 AWG stranded copper conductor with 19 individual strands. It is rated for 600 VAC and insulated with PVC covered by a nylon jacket. The nominal outside diameter is 0.13 inches. The 100 foot spool suits residential and commercial branch-circuit pulls.

Conduit-Ready Construction

The nylon jacket resists abrasion when the wire is pulled through conduit or raceway. Stranded construction makes the conductor more flexible than solid wire, easing bends and terminations. Black insulation identifies the conductor for hot or switch-leg use in standard colour-coding practice. The spool packaging keeps the wire tangle-free on site.

600 VAC Voltage Limit

The insulation system is rated for a maximum of 600 VAC, so it cannot be used on higher-voltage distribution circuits. A single conductor means each circuit requires a separate neutral and ground pulled alongside. The 12 AWG size limits ampacity to the values defined by the applicable electrical code for the installation environment. Buyers needing multi-conductor cable or a larger gauge must select a different product.

Questions about this item

What voltage does the 12 AWG THHN stranded wire handle?

The wire is rated for 600VAC, which is the maximum voltage it can safely carry in building wiring applications.

What size conduit or opening does the 0.13 in. outside diameter require?

The nominal outside diameter is 0.13 in., so select conduit or knockouts sized for at least that diameter to allow smooth pulling and code-compliant fill.

How do I install the 19-strand THHN wire on a spool without kinking it?

Unreel the 100 ft. spool straight into the conduit run, avoid sharp bends tighter than the minimum radius, and secure with staples every 4.5 ft. per code.
