Diversitech w121-50 Stranded Copper Thhn Wire 12 Awg

Product Description

The DIVERSITECH w121-50 is a 50-foot coil of 12 AWG stranded copper THHN wire in black. THHN-rated wire is designed for use in conduit runs in dry or damp locations and meets the thermoplastic high heat-resistant nylon-coated insulation standard required by NEC-governed installations. The stranded copper conductor provides flexibility during pull-through, making it a reliable choice for licensed electricians running branch circuits, equipment connections, and low-voltage control wiring in HVAC, plumbing, and general electrical trade work.

This wire is suited for residential and light commercial electrical installations where a code-compliant 12 AWG conductor is required. Common applications include branch circuit wiring to HVAC equipment, panel feeders, and equipment hookups where conduit-run THHN wire is specified. The black color coding supports standard wiring conventions for hot conductors in single-phase and three-phase systems.

Key Features

• 12 AWG stranded copper construction for flexibility during installation
• THHN-rated insulation for use in dry and damp conduit runs
• Black jacket supports standard hot-conductor color coding
• 50-foot length suitable for single-run equipment connections
• Meets NEC requirements for thermoplastic high heat-resistant nylon-coated conductors

Compatibility

Designed as a general-purpose THHN conductor for use in conduit-based electrical systems in residential and light commercial applications.

Installation Notes

Installation should 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 at the panel before pulling or terminating wire. THHN wire must be run inside conduit — it is not rated for direct burial or exposed outdoor use without additional protection. Use appropriately rated connectors and terminals sized for 12 AWG conductors.
