What Is a generator Interlock Kit?

The Generator Interlock Kit is a product that allows a portable generator to be safely and conveniently connected to a home's electrical panel. The design of the kit provides the necessary protection to keep utility workers safe while the home's electrical system functions normally from the generator. This is achieved by providing a mechanical interlock, which acts as a manual transfer switch so that both the utility breaker and the generator breaker cannot be turned on at the same time which isolates the two systems.

Safety is also improved because with the Generator Interlock Kit installed, there is no need to run extension cords into the home which eliminates associated fire and tripping hazards. Our kits are designed to be installed by qualified electrical personnel and meet the strict requirements of the National Electrical code and the National Fire Protection Code.

We offer kits to fit most brands of electrical panels including Siemens, ITE, Square D, Cutler Hammer and many more. We also carry a full line of accessories to help you connect your generator to your home.

Do you need your generator because you have experienced a hurricane in Florida, Georgia or other East Coast location? Or perhaps there has been a snow storm in New England, or possibly a tornado or flood in the Midwest causing an outage but you still need power in your home. Here at InterLock Kit, we know how important it is to be able to power your home in times of need. Our custom built Kits allow you to safely and easily hook up your portable generator for convenient use when you need it the most. They are designed to be the most convenient and cost effective solution to run a home generator.
