The Leviton S11‑05821‑0IS is a heavy‑duty, specification‑grade grounding single receptacle designed for environments demanding long‑lasting durability, secure plug retention, and safe high‑voltage power delivery. Its robust construction and commercial‑grade performance make it ideal for applications in hotels, hospitals, schools, laboratories, commercial kitchens, warehouses, and industrial facilities.
This receptacle features a NEMA 6‑20R configuration, supporting 20A at 250V, making it suitable for equipment requiring a dedicated 250‑volt branch circuit. The narrow‑body design improves installation versatility while maximizing wiring room inside the box.
Built with high‑strength nylon face and body materials, the outlet resists impact, abrasion, and chemical exposure. Its triple‑wipe brass contacts ensure maximum conductivity and excellent plug retention over time. The zinc‑plated steel mounting strap provides structural rigidity and aligns flush for secure mounting.
Installation is streamlined through side‑wire termination, accommodating #14–10 AWG conductors. This professional‑grade wiring method ensures secure electrical connections and long‑term reliability. Backed by Leviton’s rigorous testing and quality standards, the S11‑05821‑0IS is engineered to survive demanding use while maintaining safety and electrical integrity.
