Transfer Switch Definition
What is a transfer switch?
A transfer switch is a device that is fed by both utility and generator power. It isolates the two types of power from each other so a back feed does not occur. National Electrical Code requires a device like this if two types of power are going to feed the house.
Please view the video below for a visual explanation of how a transfer switch works with your standby system to keep power flowing to your home in the event of an outage.
