we have Cnc Duel Power Automatic Changeover Switch
by This Duel Power Changeover Switch we Control Two power supply automatically
tow power could be grid power supply and generator power supply or inverter supply or ups supply or Solar panel supply
and in this changeover we have auto and mannual function means
if want to transfer our load automatic so first select auto
when main power and generator power supply on so load run on main power supply
and when grid supply off so load transfer on generator power supply
and when main supply comes so load run on main supply
and in mannual function we need to select position mannually
we explain all about duel power supply
utomatic changeover switch Connection in Main Distribution Board
we are going to learn how to do distribution board connection by using two diffrent Power Supply (Grid power supply and Generator Power Supply)
we are going to use two different power supply so we have to connect Auto changeover Switch (ATS) to Change over the power supply from Grid to Generator when the Grid power supply fail.
How to Wire Auto & Manual Changeover & Transfer Switch – (1 & 3 Phase)
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
The following fig-1 shows the different 1-Phase and 3-Phase connections for manual and automatic changeover and transfer switches. Lets explain one by one in detail as follows.
How to Wire Single Phase Manual Transfer / Changeover Switch?
Wiring 230V, 1-Phase Changeover Switch – IEC
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 connections 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”.
Wiring 120V & 240, 1-Phase Manual Transfer Switch – NEC
The following wiring diagram in fig-3 shows the Reliance manual transfer switch connected to the main 120/240 V panel and a portable generator. Step by step guide is posted before in the post under the title Wiring a Portable Generator Using Manual Transfer Switch for 120 & 240V.
The related wiring diagram in fig-4 shows the 2 pole manual transfer switch (GE TC10323R / GE TC35322) connected to the main 120/240 V panel and a portable generator to 240V subpanel installed for emergency power. Step by step guide is posted before in the post under the title Wiring a Generator Using Manual Transfer Switch for 240V.
How to Connect Single Phase Automatic Changeover / Transfer Switch (ATS)
If you are tired of manual operation of changeover switches, ATS is the best alternative to use then. In the following fig-5, the backup power of batteries is connected to the main distribution board through 2-Pole, single phase automatic changeover or transfer switch (ATS) and UPS / Inverter.
The working and operation of this circuit is the same as above except the automatic changeover switch (ATS) will detect the utility power when restored from the power house and automatically transfer from the Generator / Inverter to the Main Power supply. 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.
How to Wire Three Phase Manual Changeover/Transfer Switch
Fig-6 shows how to wire a four pole, three phase manual changeover switch to the main distribution board. This is the same connection as we discussed above for single phase wiring except that there are three phase wires instead of line and neutral.
The three phase utility power (L1, L2, L3 & N) are directly connected to the upper side of the manual changeover switch, while the backup power of the three phase generator is connected to the first four (right) slots of the lower side. The left side four slots connection points are connected to the load then.
Since the operation is manual, You have to change the changeover lever to the appropriate position manually to restore the power i.e. Change the lever position to the “Generator Supply” when main power is not available and then back to the “Main Power” when utility power is restored.
How to Install a Three Phase Automatic Transfer/Changeover Switch
Fig-7 shows 4-Poles, 3-Phase automatic transfer switch (ATS) connection to the main distribution board. All the wiring connections are the same as above for manual operation of three phase changeover switch but the switching operation is automatic.
In case of emergency breakdown, the automatic transfer switch will automatically divert the switching position to the “Generator Supply” and when the main supply restores, it will transfer the power flow to the “Utility Power” when using emergency generator set for backup power.
