Patent ID: 8199022

Claim:
A motor control center subunit comprising: a housing; a base module disposed within a panel of the housing for through-door electrical connectivity; a plurality of conductive line contacts that are selectively moveable between a retracted position, wherein the plurality of conductive line contacts are retracted within the motor control center subunit, and an extended position, wherein the plurality of conductive line contacts extend outside the motor control center subunit and are engaged with a power bus; a test point connector electrically connected between a test point within the motor control center subunit and the base module, the test point connector configured to relay at least one internal electrical condition of the motor control center subunit to the base module; at least one base module accessory removably connectable to the base module from outside the housing, the at least one base module accessory configured to receive the at least one internal electrical condition of the motor control center subunit from the base module; and wherein the base module accessory is configured to display the at least one internal electrical condition to a user.
