The 1876B‑BOX is a commercial‑grade, heavy‑duty single receptacle engineered to deliver reliable 250‑volt power in demanding environments. Manufactured under the trusted Cooper Wiring Devices / Eaton Arrow Hart brand, this receptacle is designed for applications where durability, electrical integrity, and safety are top priorities—such as industrial plants, workshops, commercial buildings, laboratories, and institutional facilities.
Rated for 20 amps at 250 volts, this device uses a NEMA 6‑20R configuration, providing a grounded straight‑blade connection ideal for higher‑voltage equipment. Its construction includes a high‑impact, chemical‑resistant nylon face paired with a durable PVC bottom housing, ensuring long service life even under heavy usage and exposure to harsh conditions.
The receptacle features triple‑wipe brass line contacts for excellent plug retention, reduced heat buildup, and superior electrical conductivity. A galvanized steel wrap‑around mounting yoke offers enhanced structural strength and stability, making installation secure even in oversized cutouts. Side‑wire terminals accept #14–10 AWG copper conductors, with factory‑backed‑out screws to streamline installation for electricians and technicians.
This rugged brown outlet is engineered to meet strict commercial and industrial performance standards and is well‑suited for both new installations and upgrades requiring dependable 250‑volt service.
