Before you start, prepare the following materials:
- A generator of the correct voltage rating (240 volts for most homes) – select the correct model for your needs
- 6-gauge or 4-gauge stranded copper wire – use the thicker wire if your generator has a large power output
- A three-pronged plug to match the outlet on the generator – make sure it is properly rated for the voltage of your generator
- Wire cutters and strippers – to prepare the wire for connection
- An electrical tape – to secure the connections
- An automatic transfer switch (ATS) that is compatible with your generator model – to ensure safe and efficient operation
- A circuit breaker panel – to connect the generator to your home’s wiring
- The appropriate wiring and fittings – to connect the ATS to your circuit breaker panel
- Safety equipment (gloves, goggles, etc.) – to protect yourself while working with electrical components

These are the steps you’ll need to follow to wire your generator to a breaker box:
Step 1 – Choose The Right Generator
There are many different types and sizes of generators available on the market. It’s important to choose one that is the right size for your needs. A small generator can power a few essential appliances, while a larger one can power your entire home.
Step 2 – Decide Where You Will Place Your Generator
It should be far enough away from your home to avoid carbon monoxide poisoning, but close enough that the power cords will reach. Choose a level surface on which to place your generator. The recommended distance from your home is 20-30 feet.
Step 3 – Prepare The Wiring
Once you have selected the generator, you’ll need to wire it to the breaker box. 6-gauge or 4-gauge stranded copper wire is appropriate for most generators. If your generator has a large power output, you may need to use the thicker 8-gauge wire. Use wire cutters and strippers to prepare the wire for connection.
Step 4 – Install The Automatic Transfer Switch
The ATS will automatically transfer power from the utility to the generator when it detects a power outage. It’s important to install the ATS as close to the breaker box as possible.
Step 5 – Connect The Plug To The Generator
Next, you’ll need to connect the three-pronged plug to the generator. Make sure that the plug is properly rated for the voltage of your generator. Once the plug is connected, you can now start wiring the generator to the breaker box.
Step 6 – Wire The Generator To The Breaker Box
Start by disconnecting the power from the utility. Then, connect the generator to the ATS using the copper wire. Finally, reconnect the power from the utility. Once everything is properly connected, you can now turn on your generator.
Step 7 – Test Your System
Once your generator is up and running, it’s important to test your system to make sure it’s working properly. Start by turning on a few lights and appliances. If everything is working as it should, you’re all set!
Tips For Safety And Maintenance

Now that you know how to wire a generator to a breaker box, here are a few tips to keep in mind:
- Never operate your generator indoors. Carbon monoxide poisoning is a real danger and can be deadly. The recommended distance between your generator and home is at least 20 feet.
- If you experience a power outage, don’t wait until the last minute to start your generator. Fuel shortages can occur during extended outages, so it’s important to have a plan in place.
- As always, use caution when working with electricity. Be sure to wear safety equipment, such as gloves and goggles, while working with electrical components.
- Check the oil level regularly and change it as needed. This will help to keep your generator running smoothly.
- Ensure that your generator is properly grounded. This will help to prevent electrical shocks and damage to your equipment.
- Be sure to read the manual that came with your generator. This will provide valuable information on how to properly operate and maintain your generator.
- Check the engine regularly to make sure it’s in good working condition. This includes checking the air filter and spark plugs.
Having a generator can be a lifesaver during a power outage. By following the steps above, you can wire your generator to a breaker box and be prepared for anything. Just be sure to follow all safety precautions and consult the manual that came with your generator. With a little bit of effort, you can keep your family safe and comfortable during even the longest power outage.
