1. An interlock system for a motor control center unit, comprising:
a unit housing having an operator handle;
a power connection assembly mounted within the unit housing, the power connection assembly including a set of power connectors configured to establish an electrical connection between the motor control center unit and a power bus, and a power connection position interlock operatively coupled to the power connectors; and
a unit latch interlock mounted within the unit housing and configured to engage with a cabinet of the motor control center unit,
wherein the power connection position interlock and the unit latch interlock are independently operable and are configured to interact with the operator handle to control movement of the operator handle based on both an engagement state of the unit latch interlock and a position of the power connection assembly.
