About Automatic Transfer Switches
Automatic transfer switches connect a standby generator to your home or business and enable it to automatically turn on during a power outage. We offer switches from top brands like Generac, Kohler, and Briggs & Stratton.
Shop by Installation:
There are three types of automatic transfer switches.
- A service disconnect transfer switch energizes your entire electrical breaker panel for complete backup power. It is installed between your electric meter and breaker panel and includes a built-in service disconnect switch that allows you to disconnect the generator from the electrical system when necessary.
- A standard automatic transfer switch also powers your entire panel but does not include a built-in service disconnect switch. Instead, you will need to install a service-disconnect separately.
- A load center transfer switch powers only the essential items you need backed up during an outage. These switches require the electrician to wire the most critical circuits on your breaker panel individually.
Shop by Amps:
Find the right-sized automatic transfer switch in terms of amperage. If you have a service disconnect or standard switch, match the transfer switch amperage to the amperage of your main breaker. If you have a load center switch, match the amperage to handle the circuits you need to power.
Shop by Circuits:
Shop automatic transfer switches based on the number of circuits they can handle.
How Does an Automatic Transfer Switch Work?
An automatic transfer switch monitors utility power flowing into your main breaker panel. If a power outage interrupts that power flow, the switch will signal the standby generator to turn on. After the generator warms up for a few seconds, the transfer switch switches the incoming power for the home from the utility to the generator. Once the utility power is restored, the switch will transfer back to the utility power and signal the standby generator to turn off.
