Hubbell DS320I Decorator Switch 20A 120-277V Three Way

Product Description

The HUBBELL DS320I is a specification-grade, three-way decorator rocker switch rated for 20 amperes at 120 to 277 volts AC. Built from thermoplastic with a zinc-plated steel bridge, it is designed for commercial and residential wiring applications where durability and code compliance matter. The switch accepts back-wire and side-wire terminations and includes a snap-in connector system that allows the connector to be wired into the wall box before trim-out, reducing on-site installation time. Large silver alloy contacts limit contact erosion for extended service life. Licensed electricians are the primary installers for this device.

The DS320I fits into standard decorator-style wallplate openings and is suited for three-way switching applications in offices, corridors, stairwells, and other commercial or residential spaces requiring switching from two locations. Its voltage range of 120 to 277 VAC makes it compatible with both standard residential circuits and higher-voltage commercial lighting circuits. The ivory finish matches common decorator-series wallplates. The part belongs to the Hubbell Wiring Style Line Series DS family.

Compatibility

Designed as a specification-grade OEM-style three-way decorator rocker switch for standard decorator wallplate openings in 120 to 277 VAC residential and commercial wiring systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify zero voltage with a meter before wiring. The snap-in connector should be secured in the wall box prior to trim-out to simplify final switch connection. The self-grounding staple must make solid contact with the metal wall box to ensure proper equipment grounding continuity.
