Hubbell Incorporated HBL1556GY dimmer switch, 15 A, 120/277 V, gray

Wall switch for single-pole or three-way circuits

The Hubbell HBL1556GY is a gray toggle switch rated for 15 A at 120/277 V AC. It fits residential and light-commercial lighting circuits that need a single-pole or double-throw function. The momentary action suits control schemes where the switch returns to a centre-off position after each press. UL listing confirms compliance with applicable safety standards.

15 A capacity with 10 AWG maximum wire

The device handles loads up to 15 A and 1/2 hp motor loads, giving headroom for most branch-circuit lighting and small fan motors. Back and side wiring accept conductors from 14 AWG to 10 AWG, so installers can use standard solid or stranded copper within that range. Screw terminals provide a secure connection for each wire size. Circuits requiring more than 15 A or larger conductors exceed the switch ratings.

Toggle switch limited to 120/277 V AC systems

The switch is built for alternating-current systems at 120 V or 277 V only; it is not rated for DC or higher-voltage applications. Shatter- and crack-resistant construction and impact resistance suit normal wall-box environments. Single-gang mounting with one switch per strap keeps the footprint standard. Momentary contact and single-pole/double-throw topology limit use to control schemes that match those electrical characteristics.
