50A RV Power Extension Cord with NEMA 14-50P Plug and Pure Copper Conductors for Heavy Duty RV Use

50A RV Power Cord – The Ultimate High-Power Solution for Your Large RV or Fifth Wheel
The 50A RV Power Cord is the heavy-duty, high-capacity electrical conduit engineered to deliver maximum power to large recreational vehicles, luxury motorhomes, and fifth-wheel trailers. As the critical link between a 50-amp shore power pedestal and your RV's electrical system, this cord is designed to safely supply the substantial power required to operate multiple high-wattage appliances simultaneously—such as dual air conditioners, residential refrigerators, electric water heaters, and full-size kitchen appliances. It transforms a standard RV site into a fully functional, home-like environment, ensuring comfort and convenience on the road.

• High-Capacity 50-Amp Power Delivery: Rated for 50 amps at 125/250 volts, this cord provides up to 12,500 watts of total power (or 50A x 250V). It features four conductors (two hot legs, one neutral, one ground) to supply two separate 120V legs of 50 amps each, enabling the simultaneous operation of all major systems in a large RV without tripping breakers.
• Industrial-Grade Construction for Maximum Durability:
• Heavy-Gauge Copper Conductors: Utilizes 6 AWG (American Wire Gauge) thick, stranded copper wires for exceptional current-carrying capacity with minimal voltage drop over distance, ensuring efficient power delivery.
• Ultra-Rugged, All-Weather Jacket: The outer sheath is constructed from premium, oil-resistant, and sunlight-resistant PVC or rubber compound (often STW or STOW rated). It remains flexible in freezing temperatures, resists cracking, abrasion from rough surfaces, and degradation from fuels, oils, and UV exposure.
• Superior Strain Relief & Connector Housing: Features heavy-duty, molded rubber boots and reinforced strain relief at both plug ends. This design protects the crucial wire-to-terminal connections from pull-out, twist, and physical stress, making the cord resilient enough to be driven over occasionally.
• Secure, Standardized Connections:
• NEMA 14-50P & 14-50R Configuration: The shore power end is terminated with a NEMA 14-50P (male) plug, and the RV end has a NEMA 14-50R (female) connector. This is the universal standard for 50-amp RV service, ensuring a perfect, secure fit at campground pedestals and your RV's inlet.
• Uncompromising Safety Compliance: Manufactured to meet or exceed stringent safety standards like UL 817 and UL 62 (or CSA equivalents), guaranteeing safe operation under continuous full load.
• User-Focused Design for Convenience:
• Optimal Length Choices: Available in the most practical lengths for RVing, including 25 feet, 30 feet, and 50 feet. This provides ample reach to connect to pedestals that may not be directly beside your RV.
• Easy Handling and Storage: Despite its robust build, the cord is designed to be manageable for coiling and storage in an exterior compartment. Some models feature a bright orange or grey jacket for high visibility to avoid trip hazards.
• Weatherproof Integrity: The tight seal between the connector body and the cable, along with the molded design, helps keep moisture and dirt out of the electrical contacts.

• Unrivaled Power & Reliability for Large RVs: This is the only cord capable of fully powering a large, residential-style RV. Its robust construction ensures consistent performance, preventing power flickers or drops when multiple appliances cycle on.
• Superior Safety & Peace of Mind: The combination of heavy-gauge wiring, industrial-grade jacket, and secure NEMA 14-50 connectors drastically reduces risks associated with overheating, poor connections, and environmental damage—common concerns with undersized or low-quality cords.
• Long-Term Investment Value: Built to last for many years of frequent use, it offers far better longevity and reliability than budget alternatives, saving money on replacements and avoiding costly downtime during trips.
• Universal Compatibility & Confidence: Perfectly matches the 50-amp electrical systems in nearly all larg
