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to advantageously accommodate a full array of electrical components like most other electrical units, can be partially withdrawn from an MCC for testing while still providing protection from the possibility of shock, gases and/or other hazards by way of sealing members such as gaskets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can be mounted to the electrical unit to effectively seal the electrical unit with respect to the MCC when partially withdrawn.
