Thhn 10 Awg Stranded Copper Wire Black 500 Ft 600V 30A

Product Description

The thhn10strblk500r is a 500-foot spool of 10 AWG stranded THHN copper wire in black insulation. THHN (Thermoplastic High Heat-resistant Nylon-coated) wire is a standard building wire used in conduit installations across residential, commercial, and light industrial applications. This conductor is rated for 600 volts and 30 amps, with a 90 degrees C dry temperature rating. The 19-strand configuration provides flexibility during pulling compared to solid wire, making it easier to route through conduit runs, junction boxes, and panel installations.

This wire is suited for branch circuit wiring, feeder runs, and general-purpose electrical installations pulled through EMT, rigid metal, or PVC conduit. The black jacket is a standard color designation used for hot conductors in single-phase and three-phase systems. Licensed electricians install this wire in accordance with NEC requirements. The 500-foot spool length supports full residential service runs or commercial circuit rough-ins without mid-run splices on typical jobs.

Key Features

• 10 AWG stranded copper conductor — 19-strand construction for pull flexibility
• 600-volt rating suitable for standard building wiring applications
• 30-amp current capacity for branch circuit and feeder use
• 90 degrees C dry temperature rating per THHN specification
• PVC insulation with nylon jacket for abrasion and heat resistance
• Black jacket — standard hot conductor color coding in conduit systems

Compatibility

Designed for use in conduit systems as a general-purpose THHN building wire, compatible with standard conduit fill calculations and panel terminations accepting 10 AWG conductors rated at 600 volts.

Installation Notes

Installation must be performed by a licensed electrician in compliance with the applicable edition of the NEC and local amendments. De-energize and lock out the circuit or panel before making any terminations. This wire is rated for dry locations only at the 90 degrees C rating — verify the installation environment meets that condition. Use appropriate conduit fill calculations per NEC Chapter 9 tables when pulling multiple conductors through a single conduit.
