How do automatic transfer switches work?
ATS's constantly monitor the primary and secondary sources of power. When the primary source of power goes out, and the secondary is available, the unit automatically switches to the secondary power source. Some ATS's switch back to primary using the same logic, and some have to be manually switched back to primary. There are 'smart' switches that wait until the primary power source is available for a certain length of time (i.e. 2 minutes) until switching back, to avoid connecting to an unstable or intermittent utility source.
