Before you start connecting your generator to your home, there are a few things you need to do first.
1. Read the Owner’s Manual
This might seem like an obvious one, but it’s important nonetheless. Every generator is different, and each one has its own set of instructions.
2. Choose a Safe Location for the Generator
You’ll want to place your generator in a safe, well-ventilated location. This will help to prevent carbon monoxide buildup.
3. Make Sure the Generator Is Grounded
For safety reasons, you’ll want to make sure that your generator is properly grounded. You can do this by using a ground rod or by connecting the generator to a cold water pipe.
4. Fill the Generator with Fuel
You’ll need to have enough fuel on hand to keep your generator running for at least 24 hours. This will give you enough time to find more fuel if needed.
5. Check the Oil Level
Before starting your generator, you should always check the oil level. This will help to ensure that your generator is running smoothly and efficiently.
6. Turn Off All Circuit Breakers
Once you’ve done all of the above, you’re ready to start hooking up your generator. But first, you’ll need to turn off all the circuit breakers in your home. This will prevent any damage to your appliances or outlets.

Now that you have everything you need, it’s time to start hooking up your generator.
1. Connect the generator to the power inlet box.
You will need to use an extension cord to do this. The cord should be long enough to reach from the generator to the power inlet box.
2. Connect the power inlet box to the subpanel.
Again, you will need to use an extension cord for this. This will provide power to the subpanel.
