Southwire Armorlite 12-3 Copper THHN/THWN Cable, 250 ft Coil, 600 V

Overview

Southwire Armorlite 12-3 Copper THHN/THWN Cable arrives in a generous 250 ft coil, delivering a blend of durability and flexibility for professional wiring projects. With a 600-volt rating, it supports common residential and commercial circuits while staying easy to route through cable trays and approved raceways. The soft drawn copper conductors are designed to bend and pull smoothly, reducing resistance during installation and helping crews stay efficient on the job. The THHN/THWN insulation pairs with standard wiring practices, providing dependable performance across standard dry and damp location applications where permitted.

Key benefits

• Soft drawn copper conductors offer excellent flexibility and easier pulling through conduits and runs.
• THHN/THWN insulation supports standard wiring methods with reliable electrical performance.
• A long 250 ft coil minimizes on-site splices, helping projects progress with fewer interruptions.
• Specifically designed for installation in cable trays and approved raceways, enabling tidy, code-friendly wiring layouts.

Real‑world scenarios

In a commercial retrofit, this cable can power feeders from a panel to ceiling drops with fewer joints, reducing potential fatigue on conductors. For new construction, it supports long overhead runs in open spaces, keeping wiring organized and accessible for future upgrades. The combination of copper conductors and a robust jacket provides a dependable option for challenging installations where bend radius and pull strength matter.

Specifications and installation notes

• Copper conductors: soft drawn for easier pulling and long‑term durability
• Voltage rating: 600 volts, suitable for a wide range of power distribution tasks
• Conductor count: 12‑3, providing three active conductors plus a ground in a single jacket
• Coil length: 250 feet, enabling longer installations with fewer splices

When planning the wiring, verify local code requirements and follow proper routing, tray, and raceway practices to protect the conductors and ensure reliable performance. Armorlite 12-3 copper THHN/THWN cable offers a practical option for projects that require dependable copper conductors, straightforward handling, and a long coil to streamline on-site work.
