ABSTRACT:
An electrical apparatus of an electric distribution power system includes an electrical device having a high voltage electrical terminal that may be energized, an exterior insulating housing, and an insulator. The exterior insulating housing surrounds and insulates the electrical device, and includes an opening through which the high voltage electrical terminal protrudes such that at least a portion of the high voltage electrical terminal is external to the exterior insulating housing. The insulator covers the electrical terminal and is attached to the exterior insulating housing such that no current flow path is provided through an interface between the insulator and the exterior insulating housing.
