Prime 50ft 12/3 SJTW Heavy-Duty Outdoor Extension Cord

15 Amp Continuous Power. Primelight® Power Indicator. Engineered for Extreme Jobsite Durability.

The Prime 50ft 12/3 SJTW Extension Cord is the professional standard for high-performance power delivery on the jobsite. Built with heavy-duty 12-gauge copper wire, this cord is designed to handle the 15-amp loads required by industrial tools—saws, compressors, and vacuums—without the heat buildup or power loss common in thinner cords. Whether you’re working in the mud, sun, or sub-zero temperatures, the water-resistant and flame-retardant SJTW jacket remains flexible and durable.

Featuring the innovative Primelight® indicator, the connector glows when the cord is live, allowing you to verify power at a glance from across the site. This cord doesn't just provide power; it provides the reliability needed to keep your crew productive all day long.

Key Features & Professional Benefits:

• Heavy-Duty 12/3 Gauge: Provides superior conductivity for high-wattage tools, preventing motor burnout and ensuring your equipment runs at peak RPM.
• Primelight® Indicator Plug: The female connector features a built-in neon light that glows when power is present—eliminating guesswork and unnecessary trips to the outlet.
• SJTW Outdoor Rated Jacket: A rugged, moisture-resistant, and flame-retardant outer shell that resists abrasion from concrete and gravel.
• Extreme Weather Flexibility: Engineered to stay pliable in temperatures ranging from -40°C to +60°C, preventing the stiff coiling and cracking found in standard cords.
• Oversized Unbreakable Plugs: Extra-large molded strain relief prevents the cord from pulling away from the plug, even when subjected to heavy jobsite tension.
• Nickel-Plated Brass Prongs: Highly resistant to corrosion and oxidation, ensuring a clean, solid electrical connection for years of service.
• High-Visibility Safety Yellow: Reduces tripping hazards and makes it easy to spot the cord on busy jobsites, in tall grass, or in low-light environments.
