Southwire 529 Extension Cord 12/3 Sjtw Outdoor 50 Feet 15A

Product Description

The SOUTHWIRE 529 is a 50-foot, 12/3 gauge SJTW outdoor extension cord rated for 15 amps. Built with three-conductor 12 AWG copper wiring and a thermoplastic jacket, it handles demanding job-site loads where a lighter cord would drop voltage or overheat. The SJTW rating means the jacket is designed to resist moisture, sunlight, and abrasion, making it appropriate for outdoor use in construction, maintenance, and service work. The orange jacket improves visibility on busy job sites. Electricians and general contractors reach for this cord when running temporary power to tools, lighting, or equipment at a distance from the panel or outlet.

The 529 is suited for residential and commercial job-site applications where a heavy-duty temporary power run is needed outdoors. Common scenarios include powering rotary tools, saws, drills, and portable lighting from a standard 15-amp receptacle. The 50-foot length gives techs and tradespeople working range without requiring an intermediate outlet or piggyback cord. The 12/3 construction reduces voltage drop at longer distances compared to 14 or 16 gauge cords of the same length.

Key Features

• 12/3 gauge three-conductor construction minimizes voltage drop over 50-foot runs
• SJTW jacket rated for outdoor use with moisture and sunlight resistance
• 15-amp rating compatible with standard 15A receptacles and tool loads
• 50-foot length provides extended reach on job sites without intermediate connections
• High-visibility orange jacket reduces trip hazards and cord loss on active work sites

Compatibility

Designed for use with standard 15-amp, 120-volt outlets and tools requiring a heavy-duty outdoor-rated extension cord in residential and commercial job-site environments.

Installation Notes

Extension cords are installed by electricians and general tradespeople following OSHA and NEC temporary wiring guidelines for job-site use. Inspect the jacket for cuts, abrasion, or exposed conductors before each use and remove from service if damage is found. Never daisy-chain multiple extension cords together for a permanent run, and keep the cord fully uncoiled during use to prevent heat buildup. Match the cord rating to the connected load and do not exceed the 15-amp capacity.
