Model SD3VS Generator Interlock Kit fits Square D 3-Phase Panels having a single, centered, vertical-throw main breaker spaced approx. 8" from the top of the branch breakers.
 
The generator breaker must be mounted in the top right branch breaker position as shown.
 
This kit is not yet a full production run kit, so all components are 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!
