Fully Insulated Fuse Test and Ground Device
First Claim
1. A test and ground device for power distribution systems comprising:
- 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 disposed at least partially within the bore;
a current interrupter electrically connected between the electrical contact and a testing ground lead; and
an eye connected to a portion of the housing and proximate to the rear of the housing, the eye comprising an outer surface, wherein the outer surface of the eye is covered by the housing.

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.

23. A method of grounding and testing electrical equipment in a power distribution system comprising the steps of:
-
providing a fuse test and ground device, said device comprising; 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 disposed at least partially within the bore; a current interrupter electrically connected between the contact and a testing ground lead; an electrically conductive connection disposed within the housing and coupled to the electrical contact and the current interrupter; an eye connected to a portion of the housing and proximate to the rear of the housing, the eye comprising an outer surface, wherein the outer surface of the eye is covered by the housing; a grounding bore extending from a second aperture in the housing towards an interior of the housing and capable of receiving a permanent ground connection, wherein the grounding bore provides a point of electrical connection to the electrical contact; and an annunciator proximate to the current interrupter, wherein the annunciator provides an indication when a current flows through the current interrupter; connecting the testing ground lead to ground; mating the bore, the aperture, and the contact to a bushing; determining if the annunciator indicates that current has flowed through the current interrupter; and inserting a grounding plug into the grounding bore and connecting the plug to the point of electrical connection based on the annunciator indicating that a current is not flowing through the current interrupter. - View Dependent Claims (24, 25)
