This seems well made and installed in about 10 minutes, but mine did not come with instructions (hence only 4 stars). Luckily the Amazon listing includes a video showing how to do it. However, if I had lined it up exactly as shown in the video the alignment would have been off and it would NOT have worked. Make sure to lay the device out on the panel cover first and line it up so it will work, then mark lines for the left and right of the plate, then hold the plate only up to mark your holes. Also, there is not a lot of leeway in the hole placement, so you have to drill the holes right on. Use a brad point drill bit so it doesn't wander when you start your hole, or you could probably make the holes a little bigger than the provided bit so you have a little wiggle room.

I have installed a several versions of these for people and today on Christmas Day 2024, I installed one on a Square D 200A QO panel for my father in law. I recalled that the very first interlock I put on a Square D panel didn’t work like it was supposed to and I had to re drill the holes. This time I lined up the interlock in the position as illustrated in the instructions and noticed it would have been too far to the right and would have overlapped on top of the generator breaker’s toggle. My test fit prior to drilling the holes confirmed my suspicion and so I moved the interlock to the left as shown in my pictures; it works perfectly. To prevent aggravation, I highly recommend to test fit these things no matter what amperage or brand your breaker panel is.

Easy kit to install, measure, mark and drill. I like that they provided the right drill bit for the job in the pack. It eliminated so much guesswork for me!
