Abstract: An electrical ground connector assembly for providing a fast, secure, moisture-resistant ground connection without using special tools. The electrical ground connector assembly includes a ground rod and a cap having an tapered rod chamber for receiving the ground rod. The cap also includes a slot for receiving a ground wire. The angle of the slot may vary, depending on the diameter of the ground wire. The cap may be cylindrical or rectangular in shape. In installation, the ground wire is inserted into the slot of the cap. The upper end of the ground rod is forced into the rod cavity of the cap by any suitable manner, such as hammering the cap down over the ground rod. As the upper end of the ground rod reaches the end of the rod cavity, a compression contact is made between the wire and said ground rod. Alternatively, the ground rod can first be driven into the ground, and then the ground wire and the cap can be assembled on the ground rod.

Abstract: A device for attaching busbars of square or rectangular cross section on a support rail using electrically non-conducting support elements, which can be connected with the support rail and form a busbar receptacle adapted to the cross section of the busbar. With a simple fastener, assembly is considerably simplified because two post-shaped supports per busbar can be attached as support elements on the support rail, wherein spacing between the supports is matched to the width of the busbar and a height is matched to the thickness of the busbar. A base plate is arranged between the two supports, which insulates the busbar receptacle against the support rail and which is captively held between the holders. The ends of the supports facing away from the support rail can be closed by a strip.
