Generator Interlock Kit Compatible With Murray & Siemens 150A/200A Panels – 7/8"–1-1/4" Breaker Spacing, Aluminum Alloy, Includes Labels, Drill Bit, Screws, Instructions

About This Product

If you’ve got a portable generator and want to safely power your home during an outage without frying a lineman or your own wiring, this interlock kit is the way to go.

It’s designed to work with Murray or Siemens 150-amp and 200-amp main breaker panels where the spacing between the main breaker and the branch breaker is between 7/8 inch and 1-1/4 inches.
The kit is basically a sliding metal plate that lets you manually switch between utility power and generator power—so you can never accidentally have both on at the same time.
That’s the safety feature that makes it code-compliant and actually legal to use.

The plate is made from aluminum alloy with an anodized finish, so it resists corrosion, insulates electrically, and feels smooth to the touch.

You get everything you need: the interlock plate, three shoulder screws and nuts, a 3/16-inch drill bit, generator start-up label, reminder labels, zip ties, and full instructions.

Installation is straightforward—just drill pilot holes using the built-in guides, mount the plate, and you’re done.
Works indoors or outdoors, and they back it with solid support.

Just double-check your panel model and breaker spacing before buying.
