Southwire 3488SW0002 50 Ft 12/3 Extension Cord 15A 300V

Product Description

The SOUTHWIRE 3488SW0002 is a 50-foot, 12/3 gauge indoor/outdoor extension cord rated for 15 amps at 300 volts. It features three conductors and three NEMA 5-15R receptacles, making it a practical choice for job sites and outdoor work areas where multiple tools need power simultaneously. The SJEOW-A cord type is oil-resistant and weather-resistant, allowing use in demanding environments. At 6.3 pounds, the cord is built with enough conductor mass to handle sustained loads without significant voltage drop over its 50-foot length. It meets UL listing requirements and OSHA specifications, which are common requirements on commercial and industrial job sites.

This extension cord is designed for both residential and light commercial applications. Electricians, HVAC technicians, contractors, and other trade professionals use cords of this type to power tools, equipment, and temporary lighting during installation and service work. The yellow jacket provides high visibility on job sites, reducing trip hazards. Its indoor/outdoor rating means it can be run across concrete slabs, through wet grass, or in covered outdoor areas without degrading performance under normal use conditions.

Compatibility

Designed for use with standard NEMA 5-15P and 5-15R 15-amp, 125-volt circuits commonly found in residential and light commercial settings.

Installation Notes

Always verify the connected load does not exceed the 15-amp rating of the cord before use. Fully uncoil the cord during operation to prevent heat buildup from inductive coiling. Inspect the jacket for cuts, abrasion, or damage before each use, and take the cord out of service if the jacket or connectors are compromised. Extension cord use on job sites may be subject to OSHA 29 CFR 1926 requirements for grounding and ground-fault protection.
