When you're installing permanent electric heating systems in warehouses, workshops, or outdoor job sites, you need power delivery that doesn't fail during peak demand periods. The Fostoria GWG311303 SO power cord delivers exactly that — a heavy-duty electrical connection built for heaters requiring 6\/4 wire configuration and designed to handle the sustained current draw that industrial heating applications demand.\u003c\/p\u003e\n\n\u003cp\u003eWhat sets this power cord apart is its SO rating, which means it's built to withstand oil, moisture, and temperature extremes that destroy standard extension cords. Fostoria engineered this cord specifically for electric heater installations where environmental conditions and continuous operation create challenges for lesser electrical components. Whether you're connecting infrared heaters in a paint booth, unit heaters in a maintenance shop, or radiant heaters on an outdoor construction project, this cord provides reliable power delivery without voltage drop or overheating.\u003c\/p\u003e\n\n\u003cp\u003eThe 6\/4 wire configuration handles the high current requirements of industrial electric heaters without the voltage sag that reduces heating efficiency. At 25 feet, this cord gives you the reach needed for most permanent installations while maintaining the wire gauge necessary for full power delivery. The SO jacket construction resists cuts, abrasion, and chemical exposure that would compromise thinner power cords, making it suitable for the harsh conditions where industrial heaters typically operate.\u003c\/p\u003e\n\n\u003cp\u003eForge Claw distributes Fostoria power cords nationwide because we've seen how proper electrical connections affect heater performance and longevity. Undersized or improperly rated power cords create voltage drops that force heaters to work harder, draw more current, and fail sooner. The GWG311303 eliminates these issues by providing the correct wire gauge and environmental protection for sustained industrial heating applications.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003eThe GWG311303 power cord provides \u003cstrong\u003e25 feet of 6\/4 SO-rated cable\u003c\/strong\u003e designed for 220V electric heater connections in industrial environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eLength:\u003c\/strong\u003e 25 feet\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWire configuration:\u003c\/strong\u003e 6\/4 (6 AWG, 4 conductor)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJacket type:\u003c\/strong\u003e SO rated (oil resistant, moisture resistant)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 600V maximum\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature range:\u003c\/strong\u003e -40°F to +194°F operating\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 15.0 pounds\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmpacity:\u003c\/strong\u003e 55 amps continuous duty at 75°C\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConductor material:\u003c\/strong\u003e Fine stranded copper\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJacket color:\u003c\/strong\u003e Black SO rubber\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cp\u003eThe GWG311303 incorporates \u003cstrong\u003e4 key construction features\u003c\/strong\u003e that ensure reliable power delivery in demanding industrial heating applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSO jacket construction\u003c\/strong\u003e resists oil, moisture, and abrasion damage that destroys standard power cords in industrial environments.
