Southwire 90288802 Extension Cord 50 Ft 12/3 Awg 20A 125V

Product Description

The SOUTHWIRE 90288802 is a 50-foot, 12/3 AWG STW-type extension cord rated for 20 amps at 125 volts AC. Built with three conductors and a yellow outer jacket, it is designed for demanding job-site and field-service applications where reliable power delivery over distance is required. The STW jacket construction is rated for wet and dry locations, making it suitable for use in environments where moisture exposure is a real-world condition. Electricians and trade contractors rely on this cord to extend 20-amp circuits to tools and equipment without sacrificing conductor capacity. UL Listed for safety and performance compliance.

This extension cord is appropriate for both indoor and outdoor use across residential, commercial, and light industrial job sites. Typical applications include powering high-draw tools such as compressors, saws, and pumps that require a 20-amp twist-lock circuit. The NEMA L5-20P plug and L5-20R single receptacle configuration means it pairs with twist-lock outlets and inlets commonly found on generators, temporary power panels, and portable equipment. Its 50-foot length provides workable reach from a power source to the point of use without excessive voltage drop for the wire gauge.

Installation Notes

Installation and connection of this cord should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Before connecting or disconnecting, ensure the power source is de-energized. Inspect the cord jacket for damage before each use and do not use in applications exceeding the 20-amp or 125-volt ratings. Do not coil tightly during heavy-load operation, as this can cause heat buildup in the conductor bundle.
