Step-By-Step Guide 

Following my collected data, here’s a step-by-step guide to wiring a generator directly to the breaker panel.

1- Remove The Cover Panel 

Always make sure to unplug and turn off all the connected devices to the circuit before commencing the electrical work. Now, you can shut down your circuits and main breaker panel. In my opinion, you must be sure that there’s no electric flow to electrocute you. 

Here comes the time to remove the cover panel. All you have to do is unscrew all the screws holding the cover panel and remove it.

After removing the cover panel. You can move forward to install the interlock kit on it. Grab the drill that I’ve told you about before in the tools collection and make holes for the installation of your interlock kit. 

I recommend you put in bolts to secure the interlock kit on the panel cover. You can also select pliers to snap out the knock-out cover for the circuit breaker position. 

3- Installation Of Power Inlet Box 

Now, you’ll have to find a suitable location to install a power inlet box. I’ll suggest you choose a location where you can easily access and connect the generator set. Another way to mount your power inlet box is to build holes with the help of an electrical drill near your breaker panel. 

While installing the box outside, you must use a conduit to provide additional wire protection.  

4- Start Wiring The Connections

As you’re done with the installation of the power inlet box, you can commence wiring the connections. Let me make it more understandable for you. Run the wire from the power inlet box through the conduit to the panel breaker.

There are usually two hot wires, two neutral wires, and one ground wire in the power inlet box. You can recognize the wires by the following method. 

  • Red & Black for hot wires
  • White for neutral wire
  • Green for ground wire 

5- Install The Circuit Breaker 

You must connect the ground wire to the ground bus bar and the neutral wire to the neutral bus bar for the installation of the circuit breaker. Now, connect the two hot wires with the circuit breaker for the generator circuit connection. 

Here comes the time to install the circuit breaker on the panel board. According to my research, you must also install the circuit breaker retaining bracket included in the interlock kit. 

6- Install The Cover Panel 

Now that you have done all the above steps successfully, you should install the panel cover. You must screw all the corners of the cover panel properly. That’s it. Your generator set connection is ready to work.   

7- Time To Test Your Work 

I’ll suggest you test your work before going to operate it for big chores. First of all, connect your generator set with your power cord to the power inlet. Now, turn on your generator and switch on its built-in circuit breaker. If your generator set is running properly, you can turn on each circuit at a time to check how many circuits can run with your generator set.
