If you’ve experienced an extended power outage before, you’re familiar with the hassle of staying at a hotel or throwing away spoiled food from the fridge and freezer. You might have also had to repair frozen and burst pipes, or an unpowered sump pump might have led to a flooded, moldy basement. Those costs can be avoided if you have a whole-house generator. In fact, savings from a single outage can more than recoup your investment in a home generator.

Cummins automatic transfer switch instantly senses when there’s an interruption in service from your electric utility. It then disconnects your home from the power grid while simultaneously starting your generator and connecting it to the home’s electrical system.
A whole-house generator, or standby generator, functions by providing automatic backup power to an entire home during power outages. It's integrated into your home's electrical system and usually runs on natural gas or propane. When the generator detects a power disruption, it activates automatically. It transfers the electrical load from the grid to the generator, ensuring a smooth transition. The generator produces electricity, supplying power to essential appliances and systems. When the utility power is restored, the generator turns off, allowing your home to resume normal operation.
