Abstract
A grounding and testing device for power distribution systems includes an electrically insulated housing with a bore that extends from an aperture at a front of the housing towards a rear of the housing. An electrical contact is disposed at least partially within the bore, and the bore, aperture, and conductive contact are adapted to mate with a bushing. A current interrupter, such as a current limiting fuse, is electrically connected between the contact and a grounding cable. An annunciator is connected to the current interrupter such that the annunciator provides an indication when a current flows through the current interrupter. A lead is electrically connected to the contact to provide a connection point for a permanent ground connection.
