How to Connect Generator to House Transfer Switch
A generator can be a lifesaver during power outages, allowing you to keep the lights on, food refrigerated, and other essential appliances running. But if you’re not careful, using a portable generator to power your home can also be dangerous or expensive. The best way to connect a generator to your home’s electrical system is through a transfer switch. In this article, we’ll explain how to connect a generator to a house transfer switch and provide answers to some frequently asked questions about generator installation.
What is a Transfer Switch?
A transfer switch is a device that connects a generator to a home’s electrical system. It allows you to safely switch the house’s electrical supply from the grid to the generator, preventing back-feeding and other electrical hazards. Transfer switches come in two main types: manual and automatic.
Manual transfer switches are the most common and affordable option for home use. They require manual operation to switch the electrical supply from the grid to the generator. In contrast, an automatic transfer switch (ATS) can detect a power outage and automatically switch the electrical supply from the grid to the generator, without any input required.
Step-by-Step Guide: Connecting a Generator to a House Transfer Switch
Before we start, it’s important to note that installing a transfer switch is a job for a licensed electrician. Attempting to do it yourself could be extremely dangerous, leading to electrocution, fire, or explosion. That said, here’s a general outline of what will be involved:
Step 1: Choose the Right Generator
Before you can install a transfer switch, you need to select the right generator for your home. A few things to consider are:
– The size of your home and its electrical load
– Your budget
– The type of fuel you want to use
– The runtime you require
– Noise level
Once you’ve found the right generator, you’re ready to begin installing.
Step 2: Install the Transfer Switch
The next step is to install the transfer switch. This involves mounting the switch in the desired location, then running conduit or flexible cable from the switch to the generator.
The switch needs to be wired into your home’s electrical system, so it’s critical to hire a licensed electrician to do this. If the wiring isn’t done correctly, it could lead to electrical hazards or damage to your home’s electrical system.
Step 3: Connect the Generator
Once your transfer switch is installed, you can connect your generator. To do this, you need to:
– Locate the inlet box on the transfer switch. This is where you’ll plug in your generator cable.
– Plug in the generator cable.
– Start your generator.
– Go back to the transfer switch and turn on the generator switch.
Once the generator is turned on, the transfer switch will automatically switch the electrical supply from the grid to the generator. The generator can now power your home until the grid power is restored.

Q: Can I install a transfer switch myself?
A: No. You should hire a licensed electrician to install the transfer switch. Attempting to do it yourself could lead to electrocution, fire, or explosion.
Q: How much does it cost to install a transfer switch?
A: The cost of installing a transfer switch varies widely depending on several factors, including the size of your home, the type of transfer switch, and the location of the switch. A basic manual transfer switch can cost as little as $300, while a more advanced automatic transfer switch can cost upwards of $2,000.
Q: Do I need a permit to install a transfer switch?
A: The requirements for permits vary depending on your state and local regulations. In most cases, you will need a permit to install a transfer switch. A licensed electrician can help you navigate the permitting process.
Q: Can I use an extension cord to connect my generator to my house?
A: No. Extension cords are not designed to handle the electrical load required by a generator. Using an extension cord can cause electrical hazards and permanent damage to your home’s electrical system.
Q: Can I connect my generator directly to my home’s electrical system?
A: No. This is extremely dangerous and can cause electrocution, fire, or explosion. Always use a transfer switch to connect your generator to your home’s electrical system.
Connecting a generator to a house transfer switch is the safest and most efficient way to power your home during a power outage. Remember, though, that installing a transfer switch is a job for a licensed electrician. If you want to ensure that your home’s electrical system is safe and up to code, hire a professional to do the job.
