10 AWG THHN Building Wire

This 10 AWG THHN building wire uses a single solid copper conductor with PVC insulation and a nylon jacket. It is rated for 600 V AC and has a nominal outside diameter of 0.15 in. The brown colour coding helps identify the conductor in panel or conduit runs. Supplied on a 500 ft spool for continuous pulls.

Ideal for electricians pulling branch circuits

Contractors who need a solid conductor for easier termination on screw terminals will find this gauge convenient. Installations that require stranded wire for flexibility in tight bends or vibration-prone environments should select a different construction. The single-conductor design does not suit multi-core cable assemblies.

Solid 10 AWG conductor determines ampacity

The solid stranding supports standard breaker and device terminals rated for this gauge. It also sets the wire's current-carrying capacity for the circuit design. Verify local code requirements for the intended load before installation.

Questions about this item

Should I choose the 500 ft spool or a shorter length for my project?

The 500 ft spool provides enough wire for long runs or multiple circuits without splicing. Choose a shorter length only if the total distance is small and you want to avoid leftover material.

What does the 600 V rating mean when the wire is installed in a real circuit?

It means the insulation is tested to withstand up to 600 V AC. In typical residential or light commercial circuits the operating voltage is far lower, so the rating provides a wide safety margin.

Is the THHN designation the same as a standard building-wire spec, and what does it cap in practice?

THHN indicates a thermoplastic high-heat nylon jacket over PVC insulation. The construction caps the nominal outside diameter at 0.15 in and limits the conductor to solid 10 AWG copper for the listed ampacity.
