These Westinghouse kits are specially made to work with the Westinghouse electrical panel on your home. Each kit acts just like a manual transfer switch, allowing you to connect your generator to your home’s electrical panel quickly and safely. Relative to regular transfer switches, our Interlock kits also take less time to install so you can expect to pay less for the installation. Not sure which kit is the right one for you? Call or contact us. We’ll answer any questions you’ve got, and we’ll be happy to connect you to the right kit for your electrical panel.
