Figure 38 - Unit Interlock to Prevent Insertion - Unit Completely Withdrawn
In this position, the unit is partially removed from the MCC and the
intermediate slot in the interlock plate is in line with the bushing in the unit
support pan. When the unit is locked in this position, the unit power and ground
stabs are disengaged. This position can be used to prevent insertion of a unit into
the MCC.
