A ground fault protection device includes an electrically-conductive main body defining a reservoir having a plurality of drainage ports, and having downwardly--extending, ground-penetrating electrodes configured for minimal ground penetration. The device has handles for manual lifting and transportation, plus grounding terminals for connection of grounding cables. 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 reservoir may be filled with water, which will drip through the drainage ports and moisten the soil surrounding the electrodes, thereby decreasing the soil's electrical resistance and consequently improving electrical conductivity between the electrodes and the soil.
