When a home standby generator is set to AUTO, the automatic power transfer functionality can be tested by disconnecting utility power from the site. Note that a delay of five minutes may occur after the power is disconnected while the generator starts up and transfers power. This test will remove power to appliances in the home.
Note: This procedure is not the same as a generator exercise. To learn more about generator exercises, see the What Is a Generator Exercise? article.
1. Confirm the generator is set to AUTO and the controller displays Ready to Run. See How Do I Put My Home Standby Generator Into Auto Mode? for more information. 2. Determine if the home has a service-entrance-rated transfer switch. See What's the Difference Between A Service-Entrance Rated and Non Service-Entrance Rated Transfer Switch? for more information. 3. Locate the power disconnect for the site (service or non-service rated). Flip the switch to the off position. 4. Confirm that power transfer occurs to the generator. This can take between 5 to 20 minutes depending on configured settings. If power is transferred successfully, the generator will turn on and return power to the home. 5. When the test is complete, return the power disconnect to the on position.
