ABSTRACT:
An electrical shorting block has a molded body with a plurality of side-by-side recesses in which terminal members having first, tapped apertures are secured. A shorting bar supported in the molded body extends across but is spaced from the terminal numbers and has second apertures aligned with the first apertures. For the hot side terminal members, shorting connectors slidable through but captured by the apertures in the shorting bar have threaded ends which can be selectively threaded into the tapped first apertures of those terminal members. Helical compression springs bias the captured shorting connectors away from the terminal members when not used to short the terminal. Common terminal members are connected to the shorting bar by shorting screws which remain threaded into the first apertures. The terminal members preferably have both screw terminations and male fast-on terminations.
