Generac 100 Amp Automatic Transfer Switch Single Phase

Generac’s non-service rated automatic transfer switch enables full-circuit coverage, when an additional main disconnect is properly installed in the field.

Every home standby power system needs a transfer switch. It’s how your generator makes sure the power stays on when there’s an outage – automatically switching your home’s circuits from the grid to your generator.

Featuring a Nema 3R steel enclosure, this particular switch can be installed either indoors or outdoors.

Through the use of digital power technology (DPM), this switch has the capability to manage up to 4 individual HVAC (24 VAC controlled) loads with no additional hardware.  DPM technology – Load management systems are designed to work together to prevent a generator from being overloaded by large appliance loads.  Multiple air conditioner loads (up to 4) can be managed with DPM.  Loads to be “shed” are in 4 priority levels.  Up to 8 more loads can be managed as well, providing the most installation efficient power management options available with the use of Smart Management Modules.

Designed for use with single phase generators that utilize an Evolution or Nexus controller.  Compatible with Smart Management Modules, sold separately.
