Understanding Transfer Switches for Generators

Transfer switches are a crucial component for the safe and efficient operation of whole home generators. These components play a pivotal role in a well-integrated power backup system. This blog post explains what they are, how they work, and why they are essential for your generator setup.

What is a Transfer Switch?

A transfer switch is an electrical device that switches a load between two sources. In the context of generators, it's used to safely switch your home's power supply from the utility grid to your generator. When a power outage occurs, the transfer switch allows your home to receive power from the generator instead of the utility company.

Types of Transfer Switches

There are primarily two types of transfer switches: manual and automatic.

Manual Transfer Switches

Manual transfer switches require you to manually switch the power source from the utility to the generator. They are more cost-effective but require your presence to operate.

Automatic Transfer Switches (ATS)

As the name suggests, automatic transfer switches automatically detect a power outage and switch power to the generator without manual intervention. They are ideal for seamless power management, especially for prolonged or unexpected outages.

Why Are Transfer Switches Important?


One of the primary roles of a transfer switch is to prevent backfeeding, which occurs when electricity travels back down the utility lines. Backfeeding, which is the result of not using a transfer switch, can pose a severe safety risk to utility workers, and neighbors. Additionally, backfeeding can result in damage to your generator once the power is restored. 

Legal Compliance

In many regions, having a transfer switch is legally required when using a generator. It ensures that your generator complies with local electrical codes. 

Load Management

Transfer switches can help manage which circuits receive power during an outage, allowing you to prioritize essential appliances or areas of your home.

Automatic Transfer Switches: The Ultimate Generator Convenience 

Whether you’re asleep, away from home, or unable to attend to your generator for some other reason, automatic transfer switches can be invaluable. When the power goes out, automatic transfer switches seamlessly connect your home to your generator. This can ensure the safety and comfort of those within the home, the integrity of food in the refrigerator or freezer, and make the already stressful situation of dealing with a power outage that much easier. 

Choosing the Right Transfer Switch

When selecting the right transfer switch for your home, you’ll want to consider a few key factors: 

Generator Size

The transfer switch must match the capacity of your generator.

Power Prioritization

Consider what appliances or areas of your home you need to prioritize during an outage.
