Automatic changeover switch for generator circuit diagram

A smart way to build an automatic changeover switch or automatic transfer switch (ATS) is by using two contactors together with a good ATS or AMF controller. It is about two, electrically controlled, circuit breakers. These powerful relays are not allowed to close simultaneously, but only one at a time. The two contactors are joined together with a ‘mechanical interlock’ mechanism. It will not allow to both relays to be in a ‘closed position’. In the automatic changeover switch for generator circuit diagram, the contactors are indicated ‘KG’ for generator and ‘KM’ for mains. This guide will help you to make by your own generator control panels for standby generator. You will understand all details by following a STEP-BY-STEP 60kVA AMF panel manufacturing.
