This ETL‑listed 50 A RV power connector (NEMA SS2‑50R) delivers reliable 125/250 V shore power for RVs, trailers, campers, boats and other outdoor applications. The heavy‑duty housing is molded from glass‑fiber reinforced polyester for flame retardancy, UV resistance and impact durability, while the PVC boot cover provides high‑temperature resistance, waterproof and dust‑proof protection.

The twist‑lock mechanism creates a secure, wobble‑free connection and forms a watertight seal when the cable is turned into the receptacle. Color‑coded wiring (green‑ground, white‑neutral, black‑red‑hot) simplifies installation—just be sure the power is off before connecting. Designed for standard 4‑wire (6/3 + 8/1 AWG) cables, this kit replaces worn or damaged inlet protectors and ensures a safe, long‑lasting power link for any mobile living setup.
