How to Wire Three Phase Manual Changeover/Transfer Switchįig 4 shows that how to wire a four poles, three phase manual changeover switch to the main distribution board. Three Phase Electrical Wiring Installation in a Multi-Story Building.Three Phase Electrical Wiring Installation in Home – NEC & IEC.In case when utility power is not available, the ATS will transfer the switching position to the Inverter, hence electrical appliances will be still in operation mode without interruption through the stored power in the batteries. The working and operation of this circuit as same as above expect the automatic changeover switch (ATS) will detect the utility power when restores from the power house and automatically transfer from the Generator / Inverter to the Main Power supply.
In the following fig 3, the backup power of batteries is connected to main distribution board through 2-Pole, single phase automatic changeover or transfer switch (ATS) and UPS / Inverter. If you are tired of manual operation of changeover switches, ATS is the best alternative to use then. How to Connect Single Phase Automatic Changeover / Transfer Switch (ATS) Single Phase Electrical Wiring installation in a Multi-Story Building.Single Phase Electrical Wiring Installation in Home – NEC & IEC.When power supply restores from the power house, simply switch back the changeover switch position to the “Main Power Supply”. This way, power supply will continue to the load points through the inverter or generator. In case of power failure, the manual changeover switch can be changed to to the generator / inverter position. The left side of lower slots are connected to the main board as load. The upper portion of the changeover switch is directly connected to the main power supply while the lower first and right connections slots are connected to the backup power supply like generator or inverter. In fig 2, different connection and wiring diagrams are shown for a two pole, single phase manual changeover switch. How to Wire Automatic & Manual Changeover & Transfer Switch? – Single & Three Phase How to Wire Single Phase Manual Transfer / Changeover Switch Lets explain one by one in detail as follow. The following fig 1 shows different single phase and three phase connections for manual and automatic changeover and transfer switches. 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 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.
