Cutler Hammer Interlock Kits

We’ve specially designed several Kits to work with Cutler Hammer electrical panels. Each kit acts like a manual transfer switch, and allows you to safely connect your portable generator to your home’s electrical panel; you’ll be able to power household systems and use your power outlets as usual in the event of an outage.

In addition to allowing you to switch easily between household and generator power, our Kits are also easier to install than standard transfer switches – that means lower installation fees.

Any questions? Call anytime – we’re happy to help connect you to the right Cutler Hammer Interlock Kit for you!
