When the power goes out, you want to make sure your backup generator is ready to keep your home running smoothly. But before you plug that generator into your home’s electrical system, you might be wondering: Are generator interlock kits legal? It’s a fair question, and one that’s worth considering if you want to stay safe and avoid trouble with local codes or insurance companies.
In this article, we’ll explain what an interlock kit is, why it’s important, and whether it’s legal to use one in your home. We’ll also provide some tips on how to ensure your installation is done right. By the end of this, you’ll know exactly how to power your home safely and legally during an outage.
What is a Generator Interlock Kit?
A generator interlock kit is a simple safety device that allows you to connect a portable generator to your home’s electrical panel. The interlock prevents both your home’s utility power and the generator power from being on at the same time. It works by physically blocking the breakers in your electrical panel, so you can only turn on one, either your main power from the utility company or your generator.
This is crucial because running both power sources at once can cause dangerous “back-feeding,” where electricity flows back into the grid. This can put repair workers at risk and cause damage to your equipment. The interlock kit ensures that this doesn’t happen, keeping everyone safe.
Are Generator Interlock Kits Legal?
In most places, generator interlock kits are legal as long as they follow the right guidelines. However, the answer can vary depending on where you live. The key factors to consider are:
-
Approval and Listing: The kit must be tested and approved by a recognized safety organization, like Underwriters Laboratories (UL).
-
Proper Installation: The kit should be installed by a licensed electrician who understands local building and electrical codes.
-
Local Code Compliance: Your city or state may have specific rules for using interlock kits, so it’s important to check the local regulations.
While the kits are generally allowed, it’s always best to double-check with your local authorities or a qualified electrician before installation.
How to Ensure Your Interlock Kit is Compliant
To make sure your generator interlock kit is installed legally and safely, follow these simple steps:
-
Buy a Listed Kit: Make sure the kit you purchase is approved by safety organizations like UL. This ensures it meets the necessary standards for safety and performance.
-
Get a Licensed Electrician: Have a licensed electrician install the kit. They will make sure it’s set up correctly and meets local codes.
-
Check Local Codes: Some areas may require a permit or inspection for installing an interlock kit. Check with your local building department to see if that applies to you.
-
Don’t Forget the Main Breaker: Always make sure to turn off the main breaker before switching to generator power. This is essential for safety.
By following these steps, you can be confident that your installation is both legal and safe.
Why Use a Generator Interlock Kit?
There are several reasons why using an interlock kit is a great choice for homeowners:
-
It’s Cost-Effective: Interlock kits are generally cheaper than full transfer switches, which can save you money on installation.
-
It’s Safe: The interlock kit prevents dangerous back-feeding and protects both you and utility workers.
-
It’s Flexible: You can choose which circuits in your home you want to power with the generator, depending on your needs.
Using an interlock kit is a simple and affordable way to ensure that your backup power system is safe, legal, and effective.

Things to Be Careful About
While interlock kits are generally a safe solution, there are some things to keep in mind:
-
DIY Installations: If you try to install the kit yourself without professional help, you might end up breaking local codes or voiding your insurance. Always hire a licensed electrician.
-
Overloading the Generator: Make sure not to overload your generator by connecting too many appliances at once. This can damage the generator or cause a fire.
-
Old Electrical Panels: Some older electrical panels may not work well with interlock kits. If your panel is outdated, check with an electrician to see if an upgrade is necessary.
By being mindful of these potential risks, you can avoid common mistakes and ensure your system runs smoothly.
