The Model SQD-8 Interlock Kit fits Square D Panels having a standard full size horizontal-throw main breaker nd approximately 8 1/2" spacing from the bottom of the main breaker knockout to the top of the gen breaker knockout as shown.
 
The generator breaker will occupy the top position in the RIGHT breaker stack.
 
This kit is not yet a full production run kit, so it is not our signature blue anodized color. It is precision CNC machined from solid aluminum billet however, and looks very professional and fits very well. The kit includes everything necessary to complete the installation including all hardware, the correct size drill bit, name brand thread lock compound, a full warning placard set, and clear installation instructions.
 
All of our interlock kits are proudly made in the USA!
