Southwire 2548SW0052 Outdoor Extension Cord 50 Ft 12/3 Awg

Product Description

The SOUTHWIRE 2548SW0052 is a 50-foot outdoor-rated extension cord built with 12 AWG, 3-conductor SJTW construction. It carries a 15-amp, 125-volt rating and is designed for demanding jobsite and outdoor service environments where cord durability, ampacity, and weather resistance are non-negotiable. The SJTW jacket resists moisture, abrasion, and temperature swings, making this cord suitable for extended outdoor use. Electricians, HVAC techs, and trade crews rely on 12/3 cords at this length to run power tools and equipment without the voltage drop associated with lighter-gauge alternatives. The cord terminates with a NEMA 5-15P straight blade plug on one end and a single NEMA 5-15R receptacle on the other.

This cord is sized for outdoor applications where a full 50-foot reach is needed between a power source and work area. Common scenarios include HVAC equipment startup, rooftop or exterior electrical work, irrigation and pump servicing, and general construction site power distribution. The 12-gauge conductors support continuous 15-amp loads at the full 50-foot length with acceptable voltage drop for most hand tools and motor loads. The green and yellow jacket color makes it easy to identify on a busy jobsite.

Compatibility

Designed for use with standard NEMA 5-15 outlet configurations in residential and light commercial outdoor applications. Compatible with 15-amp, 125-volt circuits as defined by NEC Article 210 branch circuit requirements.

Installation Notes

This cord is intended for temporary power distribution and should not be used as a permanent wiring method per NEC guidelines. Inspect the jacket and plug blades for damage before each use and replace the cord if the insulation is cracked or the plug is bent. Do not exceed the 15-amp current rating and avoid running the cord under rugs, through walls, or in concealed spaces. Ensure the supply circuit is de-energized before connecting or disconnecting the cord in wet or damp locations.
