Thinking about upgrading your home’s generator? Generac generators are some of the most reliable units on the market. Similar to other brands, they have an automatic transfer switch (ATS) that allows them to switch on within seconds of an outage.
Understanding how this component works is key for knowing what to expect from your generator when you lose power.

Understanding the Automatic Transfer Switch in Generac Generators
Without a functioning ATS, even the most powerful generator engine becomes nothing more than a lawn ornament. But how does this component work, exactly?
Think of the ATS as your generator’s brain. It makes the transition from utility power to generator power completely hands-free.
It’s constantly listening to the electrical frequency and voltage coming from your utility company. If the voltage stops completely, it sends the start signal to your Generac generator.
The ATS doesn’t just wait for total blackouts, either. Instead, it switches on even when the voltage drops below a certain level. It does this to protect your sensitive electronics, which can be damaged when they don’t receive enough power. Typically, falling below 80% of standard voltage is considered an unsafe threshold.
With the ATS’s fast response, you can be sure your generator is warming up even before your home is disconnected from the power grid.
Mechanical Isolation
The ATS doesn’t just turn your Generac generator on. It actually plays a crucial role in safety.
It’s dangerous to have two power sources connected to your home at the same time. The ATS acts as a mechanical double-throw switch, physically breaking the connection to the utility power. This makes it safe to switch to generator power without any back-feeding.
Back-feeding occurs when your generator sends electricity back onto the grid lines, potentially electrocuting utility workers who are repairing the outage.
By keeping both forms of power separate, you can keep yourself and others safe.
Smart Load Management
The ATSs in Generac generators can also manage the home’s heaviest electrical loads, such as your AC system or electric oven.
The ATS carefully manages your home’s load capacity, for example, in the event every appliance turns on at once white you’re on generator power.
This is possible thanks to Generac’s smart management modules. These modules allow the ATS to shed non-essential loads if the generator starts struggling.
Once the generator stabilizes, the ATS cycles the loads back on one by one, so you avoid tripping any breakers.
How to Choose the Right Size Generator for Your Needs
Choosing the right Generac generator isn’t just about the square footage of your home. Instead, it’s mostly about the electrical load you deal with.
When you’re looking for the right size of generator, you should consider three main types of coverage:
- Essential Circuit Coverage: Choose this type of generator if you just want to keep the basics running in your home, such as: the refrigerator and freezer, sump pump, furnace blower, or small AC unit.
- Managed Whole Home Coverage: Perfect for powering medium-sized homes. Manages all the essentials, as well as a central air conditioner, electric water heater, well pump, and some kitchen appliances.
- Complete Whole Home Coverage: These Generac generators are best for larger homes or families who want to use multiple appliances and AC units simultaneously.
