Generac 150 Amp Next Gen Automatic Generator Transfer Switch, SE Rated, SPD | Integrated Surge Protection Device, Service Entrance Rated, NEMA 3R Outdoor Enclosure, Fuse Control Board Generation

WHOLE-HOME STANDBY POWER FOR SINGLE-PHASE RESIDENTIAL SYSTEMS: Rated at 150 amps on a 120/240V single-phase circuit, this service entrance-rated ATS supports whole-home backup power for central AC, well pumps, water heaters, and all essential circuits

FULLY AUTOMATIC TRANSFER — NO MANUAL ACTION REQUIRED: The generator controller manages all power sensing, timing, and transfer commands automatically, so backup power activates within seconds of an outage without any intervention from the homeowner

OPEN-TRANSITION SWITCHING PREVENTS UTILITY BACKFEED. The open-transition design ensures utility and generator power are never connected simultaneously, physically blocking reverse current flow into the grid to protect utility workers and comply with NEC Article 702

FACTORY-INSTALLED WHOLE-HOME SURGE PROTECTION DEVICE. Integrated 50 kA-rated SPD redirects transient voltage spikes away from appliances and electronics during utility surges or generator transfer events — no separate surge protector installation required

NEMA 3R ALUMINUM ENCLOSURE RATED FOR OUTDOOR INSTALLATION: The corrosion-resistant aluminum enclosure with electrostatically baked powder coat deflects rain, sleet, snow, and ice, so the unit can be mounted indoors or outside at the service entrance
