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 ground lead;
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; and
a connection point positioned within the housing for a ground connection, wherein the connection point comprises a grounding bore extending from a second aperture in the housing towards an interior of the housing and capable of receiving the ground connection, wherein the grounding bore provides a point of electrical connection to the electrical contact.

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.

16. 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 (17, 18)
