Generator Interlock Kit Compatible with Square D QO or Homeline 150 or 200 amp panels. 1 3/8 inches Spacing between main and generator breaker, Professional and Interlock Kit (SD200A)

Just installed on my electrical panel. Works as intended. Like the quality & thickness. Smooth operation. Be aware that your panel holes maybe slightly off from the required position from instructions. This is no fault of the item or manufacture but rather inconsistence with panel manufactured. Just drill the holes in panels slightly higher.

Easy to install.Reasonably priced

Clear instructions for DIY. Quality part and fits perfectly. Functions as intended and great value for your money. Powers off main and powers on generator breaker keeps you and others safe .

Kit works fine with my Square D Homeline 200A panel. However, as noted by other reviewers, the instructions are not correct for the mounting placement. The photos in the instructions show the mounting location too far to the right. Other reviewers have included useful photos that illustrate the proper placement.

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.

This one fit! I have a Square D QO panel with the 200 amp mains breaker at the bottom center of the panel, 1-1/2" gap. We installed the 50 amp generator inlet breaker just above on the left rail and this interlock works! It installed cleanly and is easy to use. Definitely recommended.

Works just like the description says. It fits perfectly.

Easy install, and although I haven't needed to switch out yet, this will do the job. It is an inexpensive option for safely hooking a back-up generator into your service box.

This generator interlock kit works great. Any dummy can install it.

c'est bien installer et est efficace donc sans risque

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!
