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.
Claims25
A motor control center subunit comprising:
- a housing;
- a base module disposed within the housing for through-door electrical connectivity and configured to relay at least one internal electrical condition of the subunit;
- at least one base module accessory removably connectable to the base module and configured to receive at least one internal electrical condition of the subunit;
- and
- wherein the base module is configured to allow a user to determine at least one internal condition of the subunit to the accessory.
A motor control center comprising:
- a motor control center frame having at least one compartment;
- a motor control center subunit constructed to seat in the at least one compartment of the motor control center frame;
- an actuating mechanism attached to the motor control center subunit to control movement of a plurality of conductive line contacts;
- and
- a subunit tester configured to relay a condition of the conductive line contacts outside the subunit to a user.
A method of manufacturing a base module for a motor control center comprising:
- constructing a motor control center subunit to seat within a motor control center;
- constructing a front panel for the motor control center subunit;
- disposing a base module within the front panel;
- and
- attaching test point connectors between the base module and at least one internal component of the motor control center subunit to convey signals indicative of operation conditions of the motor control center subunit.
