Thhn 3/0 Awg Stranded Copper Wire 225A 600V Green Cut to Length

Product Description

The thhn3/0strgrnmr is a 3/0 AWG stranded copper THHN building wire with green PVC thermoplastic insulation and a nylon jacket. Rated at 600 volts and 90 degrees C in dry conditions, this conductor handles up to 225 amps at 90 degrees C, 200 amps at 75 degrees C, or 165 amps at 60 degrees C. The 19-strand configuration provides flexibility during pull-through and termination. This wire is sold cut to length, making it practical for custom runs without excess material. It is a standard choice for licensed electricians working on branch circuit, feeder, and service entrance wiring in commercial and residential installations.

This conductor is used in conduit systems for branch circuits, feeder runs, and equipment grounding applications where a green-insulated conductor is required by NEC for equipment grounding conductors. The 3/0 AWG size is commonly used in medium-load commercial panels, subpanel feeds, and large motor branch circuits. Its nylon jacket reduces friction during conduit pulls and adds resistance to oils and solvents encountered in mechanical and industrial environments. The cut-to-length format suits service calls and project-specific pulls where spool quantities are not practical.

Key Features

• 3/0 AWG 19-strand copper conductor for flexibility and reliable conductivity
• Ampacity rated at 225 amps at 90 degrees C in dry conditions
• 600-volt rating suitable for standard branch circuit and feeder applications
• Green PVC thermoplastic insulation with nylon jacket for conduit pull ease
• THHN type insulation rated to 90 degrees C dry per applicable standards
• Cut-to-length format reduces waste on custom or service-call installations

Compatibility

Designed for use in conduit as an equipment grounding conductor or current-carrying conductor in residential, commercial, and light industrial electrical systems where THHN 3/0 AWG green wire is specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize all circuits and verify absence of voltage with a meter before making any terminations. THHN wire must be installed inside an approved conduit or raceway — it is not rated for direct burial or exposed outdoor use without additional protection. Green insulation designates this conductor for equipment grounding purposes per NEC Article 250; confirm application requirements before use.
