DESCRIPTION STANDARD FEATURES

The Generac EZ Switch™ is designed to operate with 8-17kW air-cooled generators. This 100 amp Transfer switch has an integrated load center for picking up the emergency circuits. It is especially useful where the main service is large and only a portion of the building load will be served by the generator. It is available with a built in 10, 12, 14 or 16-circuit load center to supply only those circuits that are essential during an emergency. All standard and load center transfer switches are UL and CUL Listed and suitable for use as optional standby systems (NEC702).

All EZ Switches are housed in a steel NEMA 1 enclosure, with electrostatically applied and baked powder paint. The Heavy Duty Generac Contactor is a UL recognized device, designed for years of service. The control at the generator handles all the timing, sensing and exercising functions.

CONTACTOR RATING

The transfer switch contactor is rated at 250 VAC and is available in a single phase configuration only.
