Motor control center interconnection method and apparatus

摘要

In one embodiment, the components within each respective unit of the MCC are connected powered by a connector assembly that is directly engaged to secondary power and network data conductors disposed of within the enclosure. The connector assembly, if so desired, will maintain connection even upon disengagement of the unit from the main power supply. This service position can be employed to provide a safe environment for diagnostic testing and repair of the unit. In another embodiment, the secondary power and network data conductors may by carried over an open rail system. This embodiment provides a convenient means of quickly and easily engaging the secondary power and network data conductors to the unit. Another embodiment provides a method for placing the unit into a service position.
