This AC WORKS brand protective adapter [S1450CB620] is a heavy‑duty 1‑foot pigtail designed to convert a NEMA 14‑50P 50 Amp RV/generator/range plug to a NEMA 6‑15/20R 20 Amp, 250 Volt T‑blade connector. An integrated 20‑Amp breaker provides added protection by tripping power when the connected device draws more than 20 Amps. Built with an STW 10/3, 600‑Volt anti‑cold‑weather jacket, the adapter stays flexible in extreme temperatures and is commonly used for residential applications, generators, construction sites, industrial equipment, and some EV brands that accept a 6‑20 plug. cETLus Listed.
