  • Versatile 2-in-1 Design: Perfectly bridges the gap between your generator and power source. Connect your generator (NEMA 14-50P) to an RV inlet (SS2-50R) or use it as a dedicated RV power extension cord. Simply remove the pin on the SS2-50R plug if you need to adapt to standard CS6375 inlet boxes—compatible with all major RVs and generators.

  • Secure Twist-Lock Safety: Engineered with a NEMA SS2-50R twist-lock connector that locks tightly into place, preventing accidental disconnection from wind, vibration, or heavy use. Ergonomic grip handles on both male and female ends make plugging and unplloading safe and effortless, even with heavy gloves.

  • Heavy-Duty Copper Conductivity: Built with 100% copper wire core featuring 6/3 + 8/1 AWG STW rating. This ensures optimal conductivity for up to 12,500W (250V) or 6,250W (125V) loads without overheating, reducing voltage drop over long distances.

  • ETL Listed & Weather Resistant: Fully ETL certified for safety compliance. The cable is encased in a flame-retardant, heat-resistant PVC sheath that withstands outdoor elements like rain, sun, and wear-and-tear. Molded plugs provide extra protection against moisture ingress.
  • Effortless Storage & Organization: Comes with a dedicated cable organizer to keep the heavy-duty cord tidy and manageable when not in use. Ideal for stashing in a garage, RV storage bay, or emergency kit.

  • Reliable Emergency Power: Whether facing blackouts, hurricanes, storms, or floods, this cord delivers a stable, safe power supply to keep your family’s essential appliances running during outages.

FAQs About 50 Amp Generator Extension Cord NEMA 14-50P to SS2-50R, 10/25/50 Ft

Yes — unplug the removable pin on the SS2-50R end to convert it into a standard 50A RV extension cord compatible with campsite pedestals and RV park hookups.


Yes. The water-resistant molded plugs and flame-retardant PVC jacket are designed for outdoor use in rain, heat, and varying weather conditions.

Measure the distance from your generator's planned outdoor location to your home's inlet box or transfer switch. Add 5–10 FT for routing slack. When in doubt, size up — a longer cord can always be coiled, but a short one can't reach.
