Transfer Switch FAQs

  • How does an automatic transfer switch work?

    The transfer switch is an essential part of the home backup system. Its primary function is to prevent your home from being powered by utility and generator power at the same time. If utility power is lost, the generator control panel senses the loss and tells the transfer switch to close off the connection with utility and complete the connection with the generator so it can begin providing power to the home.

  • How is the automatic transfer switch connected to the house/generator?

    This can vary by the type of transfer switch and depends on the number of circuits you would like covered.
    In a partial home application, the transfer switch is installed similarly to a subpanel, and the circuits that are covered by the generator are moved either into a circuited transfer switch, or are installed in a subpanel that is protected by a non-circuited transfer switch.
    In a whole home application, the transfer switch is installed between the incoming utility power source and the home’s distribution panel.
     

  • Why doesn't every home standby generator comes with a transfer switch if they are required?

    Each application is different, as homes and businesses have varying power needs. Providing the correct size generator and transfer switch is important to ensuring proper coverage, and offering the generators and transfer switches separately allows you to get exactly the size you need, helping to keep cost down. A Generac Authorized Dealer can help you size the right generator and transfer switch for your needs.
