Fits Siemens 200A Panels with Horizontal-Throw main breaker and left-mounted generator breaker if the main breaker is top mounted, or right mounted generator breaker if the main breaker is bottom mounted as shown here. (The generator breaker mounting position, left or right side,  is just the opposite of the standard model SM-200 interlock)
 
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!
