Generator Safety You Can Count On.

When the power goes out, a portable generator can keep your home running,  but only if it’s connected the right way. Interlockkit builds MET Listed generator interlock kits and carries the inlet boxes, power cords, and portable generators you need to safely connect your backup power to your electrical panel, so you can power what matters without back feeding the grid. Our kits fit nearly every major panel including Eaton, Square D, Siemens, GE, and more. Each one code-compliant, NEC-aligned, and ready to install. With stainless steel hardware, laser engraved safety markings, and panel-specific fitment, every detail is built to the standard your home deserves.
