Abstract: The present inventors have recognized that electrical units for Motor Control Centers (MCC's) can be improved to allow testing in a partially disconnected state while providing ingress protection through the use of sealing members without decreasing the size of the electrical unit. In particular, a full size electrical unit, able to advantageously accommodate a full array of electrical components like most other electrical units, can be partially withdrawn from an MCC for testing while still providing protection from the possibility of shock, gases and/or other hazards by way of sealing members such as gaskets and/or plates. Such sealing members can be mounted to the electrical unit to effectively seal the electrical unit with respect to the MCC when partially withdrawn.

Abstract: A network distribution adapter may be configured to vertically connect a network cable on one side of an isolation wall (within a vertical wire-way) while connecting another network cable at an angle on an opposing side of the isolation wall (interior to the MCC). This may advantageously allow fitting the adapter in the limited space provided by the vertical wire-way while also providing more reliable protection for the network connections. In one aspect, the network distribution adapter may include a printed circuit board (PCB) which couples a first connector disposed in a first plane parallel to the PCB with a second connector disposed in a second plane at an angle to the first plane. The PCB may be mounted in a housing which, in turn, may be mounted in relation to an opening in the isolation wall.
