Manual and Automatic Transfer and Changeover Switch Wiring & Connection
In our step by step electrical wiring installation tutorials series, We will show how to wire and connect single phase and three phase automatic and manual changeover and transfer switches to the home distribution board and main panel to use the backup power supply such us batteries power with UPS and inverters or generator power in case of emergency breakdown and power outage. The wiring diagrams show both the 120V/240V NEC and 230V/400V IEC system voltages (single phase and three phase supply) for manual and auto transfer and changeover switches. Now let’s begin as follows.

In fig-2, different connection and wiring diagrams are shown for a two pole, single phase manual changeover switch. The upper portion of the changeover switch is directly connected to the main power supply while the lower first and right connection slots are connected to the backup power supply like generator or inverter. The left side of lower slots are connected to the main board as load.
In case of power failure, the manual changeover switch can be changed to the generator / inverter position. This way, power supply will continue to the load points through the inverter or generator. When power supply restores from the power house, simply switch back the changeover switch position to the “Main Power Supply”.
