An Automatic Transfer Switch (ATS) is a device that automatically transfers your home’s electrical load from the utility grid to your generator during a power outage. It provides a safe, smooth transition so your essential systems stay powered without manual switching. When utility power is restored, this equipment switches the load back and shuts down the generator, helping maintain a stable, uninterrupted power supply in your home.
If an ATS fails, your generator may start but not deliver power to your home, or the system may not switch back to utility power once it is restored. This can cause inconvenience and possible system strain. Regular inspections, testing, and maintenance help reduce the risk of ATS failure and ensure reliable operation during outages.
No, an ATS is not a generator. It works as the control hub for your generator system. The Automatic Transfer Switch detects a loss of utility power and automatically signals the generator to start.
In most homes, the size of the ATS should match the amperage of the utility service. For example, a home with a 200-amp service typically requires a 200-amp ATS. However, if your generator provides partial home or limited circuit coverage, a smaller ATS may be sufficient.
