Key Performance Features

⚡ Immense 12,500W Continuous Power Threshold

Rated for 50 Amps at 125/250V, this line provides the electrical capacity needed to safely run your entire rig, high-draw climate systems, and remote workstation gear simultaneously.

Industry-Standard N14-50 Connectors with Grip Handles

Features the most widely used industrial configurations: an N14-50P male type plug and an N14-50R female type outlet. Molded with a compact, heavy-duty loop handle on each end, the ergonomic grip makes it easy to plug in or disconnect safely, even from tight pedestal boxes.

100% Pure Copper 4-Wire Conductor

Internally configured with a thick 6AWG/3C + 8AWG/1C layout forged entirely from pure copper conductors. This elite build reduces resistance, prevents voltage drops, and minimizes heat buildup over long-term high-amperage use.

️ Wear-Resistant All-Weather STW Jacket

The outer jacket is extruded from tough, wear-resistant PVC compound to form a heavy-duty STW weather shield with a 26.5mm (1.04") outside diameter. This fully sealed insulation resists rain, oils, abrasion, and direct sunlight while remaining highly flexible across a wide temperature range from -40°F to 140°F (-40℃ to 60℃).

️ Versatile Utility & ETL Approved Safety

Carries official ETL Listed Certification, ensuring your setup is guarded against line faults and electrical short hazards. While perfect for hooking up large travel trailers, motorhomes, and campers, it can also double as a high-performance extension line for industrial electric welders and remote backup generators.
