Patent ID: 8007312

Claim:
A test plug assembly for use with a test switch assembly connected to one or more electrical circuits, each of said electrical circuits having quantifiable characteristics when said circuit is in operation, said test switch assembly comprising one or more test switches, each of said one or more test switches associated with a respective one of said one or more electrical circuits, the test plug assembly comprising: one or more test plug modules positioned in a stacked arrangement, each of said one or more test plug modules adaptable for in-service measurement of said quantifiable characteristics of said associated one of said one or more electrical circuits when said circuit is in operation and said test plug assembly is mated with said test switch assembly, at least one of said one or more test plug modules having an outwardly extending, electrically conductive blade for receipt in that one of said one or more test switches associated with said in operation electrical circuit whose quantifiable characteristic is to be in-service measured by said at least one test plug module when said test plug assembly is mated with said test switch assembly, said blade being electrically connected within said one or more test plug modules to a first electrical connector adapted to receive an external electrical plug, each of said one or more test plug modules further including a first thru-hole; an end plate positioned on each end of said one or more test plug modules; a handle spaced from said one or more test plug modules, extending between said end plates and secured thereto; a first rod extending between said end plates and secured thereto; and wherein said first thru-hole of each of said one or more test plug modules is aligned when in the stacked arrangement, said first rod is received in said aligned first thru-holes.
