Generator Interlock Kit For Square D QO/Homeline 150-200A Panels – 1 3/8" Breaker Spacing, Professional Safety Lockout For Backup Power

About This Product

If you've got a portable generator and a Square D panel (either QO or Homeline), this interlock kit is pretty much a no-brainer for safe backup power hookup.
It's designed specifically for 150 and 200 amp panels, and it fits that 1 3/8-inch spacing between the main breaker and the generator breaker – so you know it's going to line up right without any extra fiddling.

Here's the deal: an interlock is basically a metal sliding plate that makes it physically impossible for both the main breaker and the generator breaker to be on at the same time.
That means you're never backfeeding into the grid, which is not only a code violation but also super dangerous for utility workers.
This kit lets you safely connect your generator without needing a separate transfer switch – way cheaper and simpler.

The construction is solid – heavy-duty metal that won't bend or warp over time.

This is the updated version, so any minor fitment issues from older models have been ironed out.
