Abstract: A wiring system includes a first mounting bracket and a second mounting bracket having respective mounting flanges configured to secure the first and second mounting brackets to a mounting surface. The first and second mounting brackets extend away from the mounting surface to a distal end where a hinge is formed. The wiring system also includes a DIN rail supported above the mounting surface by the first and second mounting brackets through the respective hinges such that the DIN rail is rotatable about the hinges along an axis of rotation extending between the first and second mounting brackets to provide access to a wire passage extending parallel to the axis of rotation under the DIN rail and through the first and second mounting brackets.

Abstract: A spring clamp assembly for an electrical terminal block includes a termination spring, a trigger and a return spring. The trigger is biased by the return spring into an opening of the termination spring to impede a clamping movement of the termination spring. A wire inserted into the terminal block trips the trigger so that it clears the termination spring allowing it clamp the exposed end of the wire against a metal terminal contact. Thus, the wire is clamped in place simply by the simple and necessary action of inserting the wire into the terminal block. The wire is removed and the assembly is reset by manually moving the termination spring to its original position, removing the wire and allowing the return spring to reset the trigger.

Abstract: An apparatus for connecting screwless terminal blocks comprising a screwless jumper link and at least two screwless terminal block center jumpers which may be quickly and easily installed onto a plurality of screwless terminal blocks. The screwless jumper link permits the connection of multiple adjacent screwless center jumpers in series without occupying any terminal block wire terminations, thus maximizing the wire density.
