When it comes to standby generators, Generac produces some of the best in the market. Installed with a transfer switch, the generator automatically powers on in case of a power outage, ensuring that you’re never without electricity. However, setting up the transfer switch can be a daunting task, especially for first-time users. In this article, we’ll walk you through the wiring diagram for the Generac transfer switch, making the process easier for you.
What is a Transfer Switch?
Before delving into the wiring diagram, let’s first understand what a transfer switch is. A transfer switch is a device that allows an electric generator to switch between the utility power and the standby power. In simpler terms, it automatically disconnects your home or business from the utility grid and connects it to the generator, ensuring that you have power even when there’s a blackout. The transfer switch also helps protect the generator and the electrical system of your home or business.
There are two types of transfer switches: manual and automatic. Manual transfer switches require you to manually start the generator and then switch the power source from the utility power to the generator power. On the other hand, automatic transfer switches are designed to switch the power source automatically, without any manual intervention.
