How to Connect a Portable Generator to Your House Transfer Switch

Power outages are often unexpected and can leave you in the dark for extended periods. However, with a portable generator and a transfer switch, you can easily keep the lights on during a power outage. In this article, we’ll take you through the steps required to connect a portable generator to your house transfer switch to keep your home powered during blackouts.

What is a Generator Transfer Switch?

A generator transfer switch is an electrical device that allows you to switch your home’s power source from your utility power to your generator’s power during a power outage. When a power outage occurs, the transfer switch automatically disconnects your home from the grid and connects it to the generator. It protects your generator from back-feeding, ensures that your electrical devices are powered up, and could prevent a fire hazard, thus, making your home safe during an outage.

What are the Benefits of a Transfer Switch?

There are several benefits to having a transfer switch installed in your home.

Safety

The primary benefit of a transfer switch is safety. When you connect a portable generator directly to your home’s electrical system without a transfer switch, the excess electricity could travel back through the utility lines. This could potentially create a feedback loop that could damage your generator, cause injury or even death to line workers who are restoring power in your area. A transfer switch ensures that no back-feeding occurs, which greatly reduces the risk of accidents or damages.

Convenience

With a transfer switch, you don’t have to worry about manually turning on the generator or carrying extension cords around the house. A transfer switch is designed to make the process of switching from the power grid to the generator automatic and convenient. You just need to make sure that the generator is connected to the transfer switch and is adequately fueled.

Protection of Electrical Devices

With a transfer switch, you can avoid power surges and brownouts that can damage your electrical devices. A transfer switch will ensure that the voltage of the generator is at the right level, and no appliances are damaged.
