Ground Grid Testing. The Interconnection Customer shall substantiate the viability of their existing ground grid to attenuate step and touch potentials near the area of the main disconnects, recloser, and metering cabinet. The existing ground grid shall be tested by a qualified testing agency, and the results of the test, including ground grid resistances (at various locations mentioned above), step and touch potential thresholds, and actual step and touch potential determinations. If the ground grid(s) cannot attenuate step and touch potentials below those prescribed by IEEE 80, an expanded ground grid design shall be presented to the Connecting Transmission Owner for their review. An acceptable ground grid design consists of a report which shows the various parameters and calculation methods involved in the design, and a design sheet showing the grid geometry, grounding rods bonding locations, and limits of the ground grid, at a minimum.
