PORTABLE GROUND CONTINUITY TESTER
First Claim
1. A portable ground continuity tester comprising a body formed of an electrically conductive material, said body comprising at least one base plate and an upstanding side wall, a handle attached at one end to said base plate and at the other end to said side wall, a battery having a pair of upstanding terminals attached to said base plate with one of said terminals being in electrical contact therewith and the other of said terminals being insulated therefrom, a receptacle box formed of an electrically conducting material attached to said side wall in electrical contact therewith, a female receptacle mounted in said box in electrical contact therewith for receiving a male plug of an electrical device being tested, an indicator light mounted in said box and insulated therefrom and connected in series with said battery, and a test lead having a test probe at one end and the other end attached to said box and insulated therefrom and connected in series with said light and said battery whereby when said electrical device is plugged into said receptacle and said probe is placed in electrical contact with said electrical device, said light is illuminated when continuity exists in the circuit thus formed.

Abstract
A portable ground continuity tester having a body formed of electrically conductive material and comprised of a base plate and an upstanding side wall with a handle extending therebetween. A battery is attached by a pair of terminals to the base plate and a box having a receptacle mounted therein is attached to the side wall. A test lead is attached at one end to the box and connected in series with an indicator light and the battery. A test probe on the other end of the test lead is used to contact an electrical device plugged in to the receptacle during testing whereby the light is illuminated when continuity exists.
