An Automatic Transfer Switch (ATS) is a critical part of any emergency power supply system. The ATS is the device that selects a power source—either normal utility power or standby generator power—and conducts the power to critical loads.

Emergency generators and automatic transfer switches are rarely required to operate. However, this often means that routine maintenance on the ATS may be overlooked.

As is the case with all your electrical power distribution equipment,
routine predictive/preventative maintenance is the only way to ensure
its continued safe and reliable operation.
