The LEVITON MFG CO R51-CBR20-00I is a 20-amp duplex receptacle built for commercial and industrial electrical installations. This 2-pole, 3-wire device features a combination back and side wired design, giving electricians flexibility during rough-in and trim-out. Heavy-duty brass power contacts deliver maximum conductivity and resist wear over repeated use cycles. The mounting strap is heavy-gauge, rust-resistant steel, making this receptacle well-suited for environments where lesser devices fail prematurely. It is sold in a package quantity of 20 units, making it practical for multi-outlet commercial jobs.
This receptacle is intended for commercial spec grade applications where devices must withstand demanding conditions, including high-traffic facilities, light industrial spaces, offices, and institutional buildings. The combination wiring configuration supports both back-wire and side-wire termination methods, accommodating a range of installation preferences and local wiring practices. Licensed electricians typically specify this device where code requires commercial grade or better at 20-amp branch circuits.
Designed as a commercial spec grade 20-amp duplex receptacle for standard residential and commercial branch circuit wiring applications where a 20-amp, 2-pole, 3-wire outlet is required.
Installation should be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and applicable local codes. Always de-energize the circuit at the breaker panel and verify absence of voltage with a tester before making any wiring connections. The combination back and side wiring options allow termination to match existing wiring configurations; do not exceed the device ampacity rating or connect to circuits outside the rated voltage. Secure the mounting strap firmly to the outlet box before completing the installation.
