Are you prepared for power outages? If not, it’s time to consider investing in a portable generator. A portable generator can provide you with backup power during an outage, keeping your essential appliances and electronics running. However, to use a portable generator safely and effectively, you need to know how to wire it to your house breaker box.

Materials You’ll Need

Before you start, gather the following materials:

  • Portable generator
  • Generator cord
  • Inverter (if your generator is not an inverter generator)
  • Transfer switch
  • Wire nuts
  • Electrical tape
  • Screwdriver
  • Pliers

Step-by-Step Instructions

1. Choose the Right Generator

The first step is to choose the right generator for your needs. Make sure the generator is powerful enough to run the appliances and electronics you need during an outage. You should also consider the generator’s runtime, which is how long it can run on a single tank of fuel.

2. Install the Transfer Switch

A transfer switch is a device that allows you to safely connect your generator to your house breaker box. The transfer switch will prevent electricity from your generator from backfeeding into the utility grid, which could be dangerous.

To install the transfer switch, follow these steps:

1. Turn off the main breaker in your house breaker box.
2. Remove the knockout on the side of the breaker box where you want to install the transfer switch.
3. Insert the transfer switch into the knockout and secure it with screws.
4. Connect the generator cord to the input terminals on the transfer switch.
5. Connect the house wiring to the output terminals on the transfer switch.

3. Connect the Generator

Once the transfer switch is installed, you can connect the generator to the house breaker box. To do this, simply plug the generator cord into the input terminals on the transfer switch.

4. Start the Generator

Once the generator is connected, you can start it. Be sure to follow the manufacturer’s instructions for starting the generator.

5. Turn on the Main Breaker

Once the generator is running, you can turn on the main breaker in your house breaker box. This will allow power from the generator to flow into your house.

6. Test the Generator

Once the main breaker is on, you should test the generator to make sure it is working properly. To do this, simply turn on a few appliances or electronics. If the appliances or electronics are working, then the generator is working properly.

7. Shut Down the Generator

When you are finished using the generator, be sure to shut it down properly. To do this, simply turn off the main breaker in your house breaker box and then stop the generator.

Safety Tips

When using a portable generator, it is important to follow these safety tips:

  • Never operate a generator indoors.
  • Keep the generator away from open flames or sparks.
  • Do not overload the generator.
  • Use a generator cord that is rated for the amperage of the generator.
  • Connect the generator to the house breaker box using a transfer switch.
  • Have a qualified electrician install the transfer switch if you are not comfortable doing it yourself.

Final Note

Wiring a portable generator to your house breaker box is a relatively simple process, but it is important to follow the instructions carefully. By following these instructions, you can safely and effectively use your generator to provide backup power during an outage.
