ABSTRACT:
A fuse test and ground device includes an insulated housing with a bore that extends from the front of the housing towards the rear of the housing. An electrical contact is disposed partially within the bore. A current interrupter, such as a fuse, is electrically connected between the contact and a testing ground lead. An eye, having it's surface insulated by the housing, can be attached to the housing and provide a connection point for manipulation of the device. A grounding bore extends from a second aperture into the housing and provides an electrical connection to the contact. A grounding plug can be connected to ground on one end and inserted into the grounding bore to create a permanent ground for the device. An annunciator is connected to the current interrupter such that the annunciator provides an indication when a current flows through the current interrupter.
