Current circuit terminal block adapter

Claim 1

In an electrical power monitoring and test system for electrical power lines including at least one terminal block for establishing electrical communication between the monitoring and testing apparatus and the power lines, the terminal block including a plurality of parallel channels extending transverse to the longitudinal axis of the terminal block, each of the channels having a set of first and a second electrical terminals disposed therein and a bus bar disposed within each channel for interconnecting each said set of first and second electrical terminals, the improvement comprising: a. an insulator board extending across the terminal block, said insulator board including a plurality of threaded apertures, each of said apertures being in axial alignment with one of said first electrical terminals of each said set of terminals; b. an electrically conducting threaded post threadedly engaging each of said threaded apertures, said post being rotatable into and out of electrical contact with the corresponding one of said first electrical terminals; and c. electrical attachment means for securing an electrical conductor to said post; whereby, each of said posts may selectively electrically engage one of said first electrical terminals of said set of terminals to provide an electrical pick-off without affecting the electrical integrity of the electrical circuit connected to the corresponding one of said set of electrical terminals.
