What is an ats panel?

Answer 1

Automatic transfer switch

An ATS (Automatic Transfer Switch) is an expensive auxiliary piece of equipment and depending on the standby situation, is not always used. In emergency situations when a power failure occurs certain establishments need instant recovery from no power. Hospitals, town water distribution systems fall into this category. Some of the less priority recovery establishments will use a manual transfer switch. This is where the operator will start the generator and then transfer the utility incoming power to the generator power to feed the load. Then you have the home owner generator that just needs the pull of a handle to start the generator and you just plug in the load. So to answer the question, not all generators need to be connected to an ATS; it depends on the situation the generator is used for.
