Hubbell DS120GY Decorator Rocker Switch 20A 120-277V Gray

Product Description

The HUBBELL DS120GY is a single-pole decorator rocker switch rated for 20 amps and 120 to 277 volts AC. It is built from thermoplastic for the top, base, and rocker, and is listed for specification-grade and commercial-grade general-purpose applications. The switch measures 1.44 inches wide by 1.54 inches deep by 4.28 inches tall and accepts 14 to 10 AWG solid or stranded copper wire. A corrosion-resistant, zinc-plated steel bridge with an automatic self-grounding staple simplifies installation and supports code-compliant grounding without additional hardware. Licensed electricians and electrical contractors install this device in commercial wiring systems where a standard decorator-style wall switch is required.

The DS120GY fits specification-grade commercial and light-industrial installations where a 20-amp single-pole switching device is needed on circuits operating anywhere from 120 to 277 volts AC. The rocker-style operator and gray thermoplastic finish make it compatible with standard decorator wallplates. It carries UL and CSA listings, making it suitable for use in projects governed by the National Electrical Code. Both back-wiring and side-wiring options are supported, giving installers flexibility based on box configuration and local practice.

Compatibility

Designed as a specification-grade single-pole decorator rocker switch for commercial and general-purpose residential wiring applications. No specific compatible model numbers or replacement part numbers were identified in the product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize the circuit at the panel and verify absence of voltage with a properly rated tester before wiring. The self-grounding staple makes contact with a metal wallplate yoke, but a direct ground conductor connection to the ground terminal is best practice in most jurisdictions. Do not exceed the device ampere, voltage, or wire-size ratings stated on the device.
