Abstract
A system and method are provided for coordinating the installation and removal a motor control center subunit with the power connection and interruption thereof. A system of interlocks and indicators causes an operator to install a motor control center subunit into a motor control center, and connect supply and control power thereto, in a particular order. Once installed, a test module system included with the subunit provides for pass-through connection of signals from equipment test points. The test module can thus relay internal conditions of the subunit to the operator without a need for disengaging or opening the subunit.
