About this item

R10‑00278‑S00 – 30A 125V/250V Black Flush‑Mount Receptacle:

A rugged, industrial‑grade power outlet engineered for heavy‑duty appliances, dryers, and workshop equipment.

The Leviton R10‑00278‑S00 is a high‑performance 30‑amp, 125/250‑volt flush‑mount receptacle designed to deliver reliable, long‑term operation in both residential and commercial environments. Engineered for demanding applications such as electric dryers, shop machinery, and industrial equipment, this receptacle features a NEMA 14‑30R configuration, providing a secure connection for 4‑wire systems requiring separate hot, neutral, and ground paths. Its shallow, low‑profile form factor allows for clean, effective installation in standard single or two‑gang boxes, ensuring flexibility and compatibility across multiple project types. 

Constructed from durable thermoplastic, the device resists impact, heat, and general wear over time. The internal contacts are engineered from heavy‑gauge, double‑wire copper alloy, ensuring excellent conductivity and long service life. For electricians, installers, and maintenance professionals, the R10‑00278‑S00 provides a smooth installation experience thanks to clearly marked terminals and support for back‑wire screw connections. This design minimizes wiring errors and accelerates installation time. 

This industrial‑grade receptacle also includes a grounding system, steel mounting strap, and compatibility with Leviton's round wallplates for a clean, professional finish. Whether used in new construction, upgrades, or appliance replacements, the R10‑00278‑S00 delivers performance, safety, and efficiency.
