Southwire is one of the largest American wire and cable manufacturers — their extension cords are built with the same copper and insulation the company produces for industrial wiring, so the conductors carry full rated amperage without the voltage drop you see in cheap imported cords. The result is a cord that runs tools at full power instead of bottlenecking them.
This 100-foot 12/3 cord is heavy-gauge, three-conductor, and rated for full amperage across the complete run — the size you reach for when you need to run a table saw, miter saw, or pressure washer a room away from the outlet. The lighted triple-tap end shows live power at a glance, and the jacket is rated for outdoor use in cold and wet conditions.
Southwire is headquartered in Carrollton, Georgia, where the company has been producing wire, cable, and electrical products since 1950. They’re the largest domestic wire manufacturer and supply the majority of the electrical industry’s copper and aluminum building wire.
