on video Automatic ATS switch wiring for mains power and emergency power


 In this case, the automatic ATS switch controls the electricity entering the building. In normal mode, it connects the mains electricity to the building, when the mains power is cut off, it automatically connects the emergency power. When the mains power switch is connected, it cuts off the emergency power and connects the mains power.

ATS switches the load to the emergency power source within its prescribed voltage preferences.

Once power is restored, the transfer switch returns the load back to the primary power source.

A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power.


An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
