If you’re living in an area where power outages are frequent, you might consider buying a generator to avoid the inconvenience. A generator transfer switch is an essential tool that makes it easy for you to switch from the main power source to the generator in case of a power outage. In this article, we’ll help you understand everything you need to know about the generator transfer switch wiring diagram.
What is a Generator Transfer Switch?
A generator transfer switch is a device that is installed between a house or building’s electrical system and a backup generator. It is designed to ensure that when the power from the grid fails, the generator automatically starts up and supplies power to the house or building. The transfer switch is responsible for switching the electrical load from the main power source to the generator.
Do I Need a Generator Transfer Switch?
If you own a generator or plan to buy one, a generator transfer switch is a must-have device. It is essential to protect your home or business from the dangers of backfeeding, which can cause injury, death, or significant damage to your electrical appliances, and even utility workers. Backfeeding is when power flows back into the power grid from the generator, which can be deadly for the people working on the power lines.
How Does a Generator Transfer Switch Work?
A generator transfer switch works by monitoring the power supply from the grid. When the power goes out, the transfer switch disconnects your home or building from the grid and connects it to the generator. When the power comes back, the transfer switch disconnects the generator and reconnects your home or building to the grid. A generator transfer switch can be automatic, which means it switches automatically when the power goes out, or manual, which means you have to switch it manually.
Types of Generator Transfer Switches
There are two types of generator transfer switches – manual transfer switches and automatic transfer switches. Manual transfer switches require manual intervention to switch from the main power source to the generator, while the automatic transfer switches do the switching automatically once the power goes out.
Manual Transfer Switches
A manual transfer switch requires a person to physically switch the power source from the main power grid to the generator. It is a simple device that is easy to install and operate. Besides, it is also an affordable choice as compared to automatic transfer switches.
How to Install a Manual Transfer Switch?
Installing a manual generator transfer switch is not a difficult task, but it requires some electrical knowledge. Here are the steps to follow:
| Step 1 | Turn off the Main Power |
|---|---|
| Step 2 | Install the Transfer Switch |
| Step 3 | Install the Electrical Box and Breakers |
| Step 4 | Connect the Wires |
| Step 5 | Test the Transfer Switch |
Automatic Transfer Switches
Automatic transfer switches are more advanced than manual transfer switches. They require no manual intervention to switch the load to the generator when the power goes out. Once the generator is running, and the transfer switch detects no power from the grid, it automatically switches the electrical load to the generator.
How to Install an Automatic Transfer Switch?
Installing an automatic transfer switch requires a professional electrician as it involves working with high-voltage electricity. Here are the steps involved in installing an automatic transfer switch:
| Step 1 | Turn off the Main Power |
|---|---|
| Step 2 | Install the Transfer Switch |
| Step 3 | Connect the Wires |
| Step 4 | Test the Transfer Switch |
