Modular test plug

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 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 at least one electrical connector adapted to receive an external electrical plug;
• 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;
• and
• wherein each said one or more test plug modules includes, on a first side, a plurality of detents and on a second side, opposed from said first side, includes a plurality of raised features arranged to be received in said detents of an adjacent one of said one or test plug modules when in said stacked arrangement.

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 switches, each of said one or more switches associated with a respective one of said one or more electrical circuits, the test plug assembly comprising:

• two plates spaced apart from each other;
• a handle extending between said two plates and removably attached thereto;
• and
• a first rod spaced apart from said handle and extending between said two plates and removably attached thereto;
• said test plug assembly adaptable for receiving one or more test plug modules positioned in a stacked arrangement in said test plug assembly between said two plates when said one or more test plug modules are received in said test plug assembly, each of said one or more test plug modules capable of 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 with said received one or more test plug modules 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 at least one test plug module 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;
• wherein said one or more of said test plug modules are received in said plug assembly by first removably detaching both said handle and said first rod from said two plates and then aligning said one or more test plug modules in said test plug assembly so that said first thru-hole of each of said one or more test plug modules is aligned when in the stacked arrangement so that first rod can be received in all of said aligned first thru-holes and be removably reattached to said two plates.
