Abstract: An electrical grounding device comprises an elongate shaft with plate members projecting radially outward from a lower region of the shaft. The shaft and plate members are made of an electrically-conductive material, and are connected such that an electric current can flow between the plates and the shaft. The device is installed by boring a hole into the earth to a selected depth less than the length of shaft above the plates. The grounding device is inserted into the borehole and driven into the earth below the borehole until the upper end of the shaft projects a desired distance above the adjacent earth surface, leaving the shaft projecting sufficiently to allow connection of grounding cables. The borehole is preferably filled with gravel or other suitable fill material, and water may be added to the fill to enhance electrical conductivity between the device and the earth.

Abstract: A ground fault protection device includes an electrically-conductive main body having downwardly-extending, ground-penetrating electrodes configured for minimal ground penetration. The device has one or more grounding terminals for connection of grounding cables, and may have handles for manual transportation. The device may be installed at a desired field location by applying downward force to the device to press the electrodes into the earth, thereby establishing an electrical connection between the grounding terminals and the ground via the main body and the electrodes. Grounding cables may then be connected between the grounding terminals and structures or equipment requiring grounding. Optionally, the main body may define a reservoir having a plurality of drainage ports.

Abstract: A ground anchor includes a body having an upper surface and a lower surface; ground-piercing members depending from the lower surface of the body, with the ground-piercing members being adapted to engage an underlying ground surface and prevent movement of the body along such ground surface; ballast positioned on or in the body, with the ballast being sufficient to maintain the ground-piercing members engaged with the ground surface when under load; and means for securing an anchor line to the body. Ground-engaging means such as a ground-engaging blade member or flanges may be attached to the ground-piercing members to increase the surface area perpendicular to the line of force to provide additional resistance to movement.
