Southwire 3487SW0002 Extension Cord 25 Ft 12/3 Awg

Product Description

The SOUTHWIRE 3487SW0002 is a 25-foot, 12/3 AWG indoor/outdoor extension cord rated for 15 amps at 300 volts. Built to SJEOW-A standards, it delivers reliable power transfer in demanding job-site and service environments. The 12-gauge, 3-conductor construction handles continuous loads without excessive voltage drop, making it a practical choice for power tools, service equipment, and temporary power runs. The yellow jacket provides high visibility on active job sites. UL Listed and OSHA-compliant, this cord is suited for both professional tradespeople and experienced DIYers working in mixed indoor/outdoor conditions.

This extension cord is designed for use in residential, commercial, and light industrial settings where a durable, all-weather power extension is required. The SJEOW-A jacket rating indicates oil-resistance and suitability for outdoor exposure, making it appropriate for HVAC service calls, electrical rough-in work, plumbing installations, and general contractor use. The single-outlet NEMA 5-15R receptacle accepts standard 3-prong plugs, and the NEMA 5-15P plug connects to standard 15-amp household and commercial outlets.
