FAQs About Transfer Switches

An automatic transfer switch, or ATS, is a device that can change the power load between two sources, typically a generator and a utility power source. When utility power goes out, an auto transfer switch immediately transfers source power to a connected backup generator or UPS system to keep the lights on without you having to flip a switch. Safe, reliable and quick, automatic transfer switches are ideal to install in healthcare facilities, data centers, schools, warehouses and other settings where functioning power is critical. We carry top power distribution manufacturers to ensure you receive a quality equipment rental every time. Learn more about transfer switches below or contact a United Rentals representative to assist you in finding your next power transfer switch.

FAQs
How does an automatic transfer switch work?

Automatic transfer switches typically have microprocessors that constantly monitor the electrical parameters of their connected primary and alternate power sources. If the ATS detects the failure of the primary power source, it will automatically change the load circuit to the alternative power source to keep the facility running smoothly.

How does an automatic transfer switch work on a generator?

Generators are usually the alternative or backup power source for large facilities and will be automatically started by a transfer switch if the primary power source fails. Automatic transfer switches can instantly signal diesel, portable and other generators to start when power failure is detected.

What are the two types of automatic transfer switches?

The two main types of automatic transfer switches are open and closed. Open transfer switches only allow one power source to run at a time and briefly delay power transfer for safety purposes. Closed ATS are more complex, allowing both power sources to run simultaneously and experience no delay due to a transfer.
