This prototype Generator Interlock Kit fits Square D 200 amp panels with a 4-pole horizontal-throw main breaker and approx.  2 5/8 - 2 3/4" spacing from main breaker to generrator breaker as shown. Since this is a prototype kit, it is not blue anodized but it is CNC machined and looks very professional. The generator breaker will occupy the top left position in the left breaker column.
