ASCO White Paper | Transferring Motor Loads Between Power Sources

The most common applications for transfer switches include power distribution circuits that serve a mix of load types, including resistive loads for building lighting and heating as well as inductive loads such as motor-driven equipment. However, some transfer switches may supply a circuit that includes one or more large motors or may feed multiple circuits that serve primarily motor loads. Examples include air handlers in large commercial buildings, air conditioning compressors for data center cooling, or the many water pumps required to operate a wastewater treatment facility.
