How Transfer Switch Works
The video above shows how a Automatic Transfer Switch (ATS) works
The Automatic Transfer Switch (ATS) also known as a Power Transfer Switch, is a safer way to use a standby generator. The ATS is connected and installed to the main electrical panel of a home. It allows a power transfer between a primary source (Tenaga Nasional Berhad in Malaysia) with a secondary primary source (which is the standby generator) when the primary power supply is interrupted. When electricity interruption occurs, the ATS will isolate the electrical panel from the main incoming supply and connects it with the standby generator.
