What Is a Generator Transfer Switch and How Does It Work?
TLDR
A transfer switch safely connects your generator to your home's electrical system, allowing it to switch from grid power over to the generator during an outage.
Without a transfer switch, electricity from a generator can flow back into utility lines, leading to dangerous conditions for both utility workers and your home's electrical system.
When an outage is detected, the transfer switch disconnects your home from the grid, starts the generator, and restores power.
Automatic transfer switches handle the process without any manual effort, making them a convenient option for homeowners.
Key Takeaways:
A transfer switch connects your generator to your home safely and switches your power from the grid to your generator during outages.
Transfer switches prevent dangerous backfeeding and are essential for safe, reliable backup power.
Automatic transfer switches, like those from KOHLER, restore power without manual effort.
What is a transfer switch on a generator? A transfer switch is a device that safely connects your generator to your home’s electrical system, allowing it to switch power sources from the utility grid over to the generator during a power outage.
Transfer switches are key for both safety and convenience — without one, electricity from a generator has the potential to flow back into utility lines, creating dangerous conditions for utility workers and damaging your home’s electrical system.
With all of this in mind, a transfer switch ultimately helps protect your electrical system by preventing backfeeding. For homeowners, a transfer switch is a crucial element that makes backup power that much more reliable and easy to use.
How Does a Transfer Switch Work?
A transfer switch continuously monitors the incoming power to your home. When the switch detects a power outage, it disconnects your home from the utility grid and signals the generator to turn on. Once the generator is running, the switch transfers electrical load to the generator, allowing your home to operate like normal.
When utility power is eventually restored, the transfer switch safely reconnects your home to the grid and shuts off your generator. This entire process typically happens within mere seconds.
There are two main types of transfer switches:
Manual transfer switches, which require you to start the generator and switch power sources on your own.
Automatic transfer switches (ATS), which handle the process without any manual effort.
Automatic transfer switches are commonly used with standby generators because they provide seamless power restoration without any hassle. KOHLER generators are designed to work with automatic transfer switches, and we offer a range of automatic switches for your home backup power system.
