This interlock kit fits Eaton Breaker Panels with BJ2200 style breakers. The interlocked breakers may be mounted on the left or right side of the panel provided that they are both on the same side and occupy the two top positions.
 
Since this kit is not yet a full production kit, it is not blue anodized. However, the interlock is CNC machined, operates smoothly, and looks very professional. The kit includes everything necessary for the install.
