Automatic transfer switch.
Transfer Panels
To safely manage and transfer the output power, transfer panels are employed. Therefore, depending on the output power and current rating of the generator set, the equipment in these panels (circuit breakers, contactors, fuses, etc.) must be at the appropriate ratings.
In automated mode applications, the generator set controller must control the switching apparatus.
To prevent difficulties with the generator set and the alternator, you must build a transfer panel so the generator set cannot be started or stopped while under load.
For applications requiring motorized circuit breakers, under-voltage release coils must be employed. You can use Changeover relays with thermal-magnetic circuit breakers in manual mode applications.
The literature that came with the generator set contains wiring diagrams for the supplied transfer panels.
An Automatic transfer switch (ATS)Â
A device that automatically switches a power supply from one source to another is known as an automatic transfer switch or ATS. You frequently use ATS in backup power systems, where if the primary power supply fails, the ATS will switch to a backup power source, like a generator. Even during a power outage, it guarantees to maintain a constant power supply.
 What are the benefits of using an Automatic transfer switch?

Restore electricity to the main electrical panel after the ATS is installed and connected to the primary power source and the backup generator. Now, the ATS should be able to automatically switch between the backup generator and the primary power source as required.
Test the ATS to ensure that it is working correctly. You can typically do this by starting the backup generator and then simulating a power outage by turning off the main power supply. The ATS should switch to the backup generator automatically and then switch back to the main power supply when you have electricity.
It is important to note that installing an automatic transfer switch can be a complex and potentially dangerous task and should only be done by a qualified electrician. If you are unsure how to install an ATS properly, contact a professional.Â
What are the steps involved in activating an Automatic transfer switch?
An automatic transfer switch (ATS) is a device that automatically switches a power supply from its primary source to a backup generator in the event of a power outage. The steps involved in activating an ATS will vary depending on the specific model and make of the switch, but in general, the process will involve the following steps:
First, make sure that the primary power source and the backup generator are both turned off and that the ATS is in the "off" position.
Next, connect the primary power source to the ATS using the appropriate cables and connectors.
Then, connect the backup generator to the ATS in the same way.
Once you connect the primary power source and the backup generator to the ATS, turn on the primary power source.
The ATS should automatically switch to the primary power source, providing power to connected devices.
To test the ATS, you can simulate a power outage by turning off the primary power source and verifying that the ATS switches to the backup generator.
It's important to carefully read the instructions provided with your specific ATS model, as the exact steps and details may vary. Additionally, have a qualified electrician install and activate the ATS to ensure that you correctly and safely.
What are the steps involved in deactivating an Automatic transfer switch?
To deactivate an automatic transfer switch, you will need to follow these steps:
First, make sure that you turn off the power to the switch. You can typically do this by switching off the main power supply or unplugging the unit from the wall outlet.
Once you turn off the power, locate the transfer switch and identify the "on/off" or control panel. You will usually find it on the front or side of the button, and you may label it with words or symbols.
Use the "on/off" switch or control panel to turn the transfer switch off. It will typically involve flipping a switch or pressing a button.
Once you turn off the transfer switch, you must verify that the power is no more flowing through the switch. You can do this using a voltage tester or checking the power outlet to which you connect the controller.
If the power still flows through the switch, you may need to disconnect the switch from the power source. You can typically do this by unplugging the unit from the wall outlet or disconnecting the wires connecting the switch to the power source.
After the switch is deactivated and disconnected from the power source, you can safely perform any maintenance or repairs that may be necessary. When you finish, you can reactivate the switch by following the steps above in reverse order.
It is important to note that deactivating an automatic transfer switch can be a complex and potentially dangerous process, so it is best to leave it to a qualified electrician or other trained professional.
