Hubbell CS320GY Three Way Toggle Switch 20A 277V Gray

Product Description

The HUBBELL CS320GY is a specification-grade, three-way toggle switch rated for 20 amps at 120 to 277 volts AC. Built with a thermoset body and nylon toggle, it is engineered for commercial electrical installations where durability and reliable switching performance are required. The switch covers a wide voltage range, supports motor loads up to 1 HP at 120 volts and 2 HP at 277 volts, and includes a ground screw for code-compliant termination. Licensed electricians install this device in commercial branch circuits as part of multi-location lighting control runs.

The CS320GY is suited for commercial and specification-grade applications including office buildings, retail spaces, schools, and other facilities where three-way switching across 120V or 277V branch circuits is required. Its side-wiring configuration accommodates standard commercial wiring practice. The gray finish and specification-grade construction make it a direct fit for commercial switchplate assemblies where a professional appearance and long-term performance are expected.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for commercial wiring. De-energize the branch circuit at the panel and verify absence of voltage before wiring. Side-wire terminals accept typical commercial conductor sizes used in 20-amp circuits. Ensure the included ground screw is terminated to the equipment ground conductor per code.
