(2) In land areas not subject to tidal fluctuation, the electrical datum plane is a horizontal plane 600 mm (2 ft) above the highest water level for the area occurring under normal circumstances. (1) In land areas subject to tidal fluctuation, the electrical datum plane is a horizontal plane 600 mm (2 ft) above the highest tide level for the area occurring under normal circumstances, that is, highest high tide. The electrical datum plane as used in this article is defined as follows:
Water depths may vary seasonally or be controlled.
Bodies of water that have been constructed or modified to fit some decorative or commercial purpose such as, but not limited to, aeration ponds, fish farm ponds, storm retention basins, treatment ponds, and irrigation (channel) facilities. Natural or artificially made bodies of water not coveredīy other articles in this Code, such as but not limited toĪeration ponds, fish farm ponds, storm retentionīasins, treatment ponds, irrigation (channels) facilities.Ħ82.2 Definitions. This article applies to the installation ofĮlectrical wiring for, and equipment in and adjacent to, The farthest extent of standing water under the applicable conditions that determine the electricalĦ82.1 Scope.
Bodies of water such as lakes, streams, ponds, rivers, and other naturally occurring bodies of water, which may vary in depth throughout the year. Under the walk surface within 75 mm (3 in.), bonded to all metal structures and fixed nonelectrical equipment that may become energized, and connected to the electrical grounding system to prevent a difference in voltage from developing within the plane.
