Key Features to Consider in a 50 Amp Generator Cord
When shopping for a 50 Amp generator cord, here are some essential factors to keep in mind:
1. Certification (UL or ETL)
Certified cords ensure the product meets strict safety and performance guidelines. Look for UL Listed or ETL Certified markings.
2. Plug Type
Most generator cords for RV and residential backup use feature NEMA 14-50P (plug) and SS2-50R or 14-50R (receptacle). Ensure compatibility with your generator and power inlet box.
3. Weatherproof and UV Resistant
Outdoor generator cords must withstand rain, sunlight, and temperature swings. A weather-resistant thermoplastic jacket or STW construction provides long-lasting durability.
4. Grip and Handling
Ergonomic grips or 90-degree handles make plugging and unplugging easier—especially in tight or awkward spaces.
5. Twist-Lock and Locking Rings
For safety during operation, twist-lock plugs (SS2-50R) prevent accidental disconnection. Some cords also feature threaded locking rings for waterproof sealing.
6. Cord Length
Choose the correct cord length based on how far your generator is from the RV or transfer switch. Standard lengths range from 15FT to 100FT.
