How to Use a Generator Transfer Switch? A Complete Guide 2023
If you live in an area where power outages are frequent or if you’re preparing for a natural disaster, a generator transfer switch is an essential tool that can keep your home running smoothly during an emergency.
A generator transfer switch is a device that enables you to safely and easily switch the power supply in your home from the utility company to a backup generator.
In this article, we’ll discuss what a generator transfer switch is, why it’s important, and how to use it.
What is a Generator Transfer Switch?
During a power outage, a generator transfer switch is placed in your home’s electrical system to convert the power source from the utility company to a backup generator.
When the electricity goes out, the transfer switch detects it and instantly changes the power source to the generator.
When utility power is restored, the transfer switch returns the power source to the utility company and turns off the generator.
Why Do You Need a Generator Transfer Switch?
A generator transfer switch is essential for the safe and efficient use of a backup generator.
During a power outage, you would have to physically disconnect your home from the utility company’s power grid and connect it to the generator if you did not have a transfer switch.
This is a hazardous and time-consuming procedure that might expose you and your family to electrical shock or electrocution.
Running a generator without a transfer switch can also cause harm to your home’s electrical system and place a burden on the generator.
Types of Generator Transfer Switches
There are two main types of generator transfer switches: manual and automatic.
1. Manual Transfer Switches
A manual transfer switch requires you to physically switch the power source from the utility company to the generator using a switch located on the transfer switch.
Manual transfer switches are less expensive than automatic transfer switches, but they require you to be present and actively monitor the power source during an outage.
2. Automatic Transfer Switches
When the electricity goes out, an automated transfer switch detects it and changes the power source to the generator.
When the utility power is restored, the automated transfer switch returns the electricity to the utility company and turns off the generator.
Automatic transfer switches cost more than manual transfer switches, but they provide more convenience and safety.
Selecting the Right Generator Transfer Switch
When selecting a generator transfer switch, there are a few important factors to consider, including:
- The wattage of your generator
- The amperage of your home’s electrical system
- The type of transfer switch (manual or automatic)
- The location of the transfer switch
- The size and type of your home’s electrical panel
