Thhn 3 Awg Stranded Copper Wire Red 600V 115A thhn3strredmr

Product Description

The THHN-GENERIC thhn3strredmr is a 3 AWG stranded copper conductor wire rated for general-purpose electrical wiring in commercial and residential applications. Built with a PVC thermoplastic insulation layer and a nylon jacket, this THHN-type wire carries a 600-volt rating and handles up to 115 amps at 90 degrees C in dry conditions. The 19-strand configuration provides flexibility compared to solid conductors, making it easier to pull through conduit on longer runs. Licensed electricians and electrical contractors install this wire for branch circuits, feeder runs, and service applications where THHN-rated conductors are specified. It is sold cut to length, reducing waste on the job site.

This wire is suited for use in dry locations where THHN conductor is code-required or code-acceptable. Typical installations include conduit runs in commercial buildings, industrial panels, and residential service upgrades. The red insulation color supports standard color-coding practices for phase identification in multi-wire branch circuits and three-phase systems. At 189 pounds per thousand feet, the weight should be factored into reel handling and conduit fill calculations on larger pulls.

Key Features

• 3 AWG copper conductor with 19-strand configuration for flexible conduit pulling
• 600-volt rating suitable for standard branch circuit and feeder applications
• Ampacity: 85 amps at 60 degrees C, 100 amps at 75 degrees C, 115 amps at 90 degrees C
• PVC thermoplastic insulation with nylon jacket for durability and pull-through performance
• Red insulation for phase identification per NEC color-coding practices
• Cut-to-length availability reduces material waste on the job

Compatibility

Designed for use in dry conduit installations where 3 AWG THHN copper conductor is specified per NEC requirements.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify zero voltage with a meter before making any connections. THHN wire is rated for dry locations only — do not use in wet or damp locations unless paired with a dual-rated THWN conductor. Use appropriate conduit fill calculations per NEC Chapter 9 to ensure compliance when routing alongside other conductors.
