Leviton Mfg Co R52-0CSB1-2WS Single Pole Switch 20A 120/277V

Product Description

The LEVITON MFG CO R52-0CSB1-2WS is a commercial-grade single-pole toggle switch rated for 20 amps at 120/277 volts AC. It is designed for commercial and light industrial electrical distribution systems where a reliable, code-compliant switching device is required. The switch supports both back-wiring and side-wiring termination, giving electricians flexibility during rough-in and trim-out. The white finish suits standard commercial decor plates. Licensed electricians install this device in commercial branch circuits, offices, schools, retail spaces, and similar occupancies governed by the National Electrical Code.

This switch is suited for single-pole switching applications in commercial buildings running 120-volt or 277-volt branch circuits. The 277-volt rating makes it compatible with fluorescent and LED lighting circuits commonly found in commercial construction. It ships in a package quantity of 20 units, which matches typical electrician jobsite quantities for multi-room commercial installs. Back and side wiring options accommodate both conduit and cable installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the branch circuit at the panelboard and verify absence of voltage with a meter before any wiring work. Torque all terminal screws to the value printed on the device body or listed in the manufacturer instructions. Both back-wire and side-wire terminals are available, but do not use both termination methods on the same conductor position simultaneously.
