The Cooper Wiring Devices 1225 is a heavy‑duty, commercial‑grade surface‑mount grounding receptacle engineered to provide safe, dependable power delivery for 30‑amp, 125/250‑volt dryer and range circuits. Designed for durability, reliability, and long service life, it is an ideal solution for both residential and commercial installations where a rugged, surface‑mounted power outlet is required.
Built with a glass‑reinforced nylon housing and a heavy‑gauge galvanized steel mounting strap, the 1225 offers superior resistance to heat, impact, and corrosion. Its NEMA 14‑30R, 3‑pole, 4‑wire grounding configuration ensures modern code compliance and secure power transmission for appliances requiring a grounded circuit.
This receptacle is particularly well‑suited for utility rooms, basements, workshops, rental properties, commercial laundry areas, and retrofit situations where installing an in‑wall box is not practical. Its large internal wiring chamber and efficient terminal layout make installation straightforward and reliable for professional electricians.
