Southwire 4187SW8802 Extension Cord 25 Ft 12/3 Awg

Product Description

The SOUTHWIRE 4187SW8802 is a 25-foot, 12/3 AWG SJTW-A extension cord rated for 15 amps at 125 volts AC. Built with three conductors and a single NEMA 5-15R receptacle, it delivers reliable power for demanding job-site applications. The 12-gauge conductors support higher-draw tools and equipment where undersized cords cause voltage drop and overheating. The yellow jacket is high-visibility and constructed to handle both indoor and outdoor environments, resisting oil, moisture, and temperature variation typical of construction and mechanical work sites. Electricians, HVAC technicians, plumbers, and general contractors routinely keep cords in this gauge range as part of standard service kit loadouts.

This cord is suited for indoor and outdoor use in residential and light commercial settings. It is appropriate for powering portable tools, compressors, lighting, and diagnostic equipment during installation or service calls. The SJTW-A jacket rating indicates suitability for outdoor exposure, including damp or wet conditions commonly encountered on active job sites. The NEMA 5-15P plug connects to standard 15-amp, 125-volt outlets, and the single NEMA 5-15R receptacle accepts the same configuration at the load end.

Key Features

• 25-foot length provides reach across standard work areas without the need for cord extensions
• 12/3 AWG construction reduces voltage drop under load for power tools and equipment
• Rated 15 amps at 125 volts AC for compatibility with standard circuits
• SJTW-A jacket rated for outdoor use including damp and wet job-site conditions
• NEMA 5-15P plug and 5-15R receptacle for direct connection to standard 15-amp outlets
• UL Listed, cUL Listed, and ETL Listed with OSHA compliance markings

Compatibility

Designed for use with any equipment requiring a NEMA 5-15P connection on a 15-amp, 125-volt circuit. Suitable as a general-purpose extension cord for portable tools and service equipment in indoor and outdoor environments.

Installation Notes

Extension cord connections should comply with NEC guidelines regarding ampacity and cord length limitations for the connected load. Always inspect the jacket for cuts, abrasion, or damage before use and replace cords that show exposed conductors or damaged insulation. Do not exceed the 15-amp rating of this cord regardless of the circuit breaker size supplying the outlet. Avoid running extension cords through walls, ceilings, or other enclosed spaces in place of permanent wiring.
