I. General
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.
Natural Bodies of Water. Bodies of water such as lakes, streams, ponds, rivers, and other naturally occurring bodies of water, which may vary in depth throughout the year.
Shoreline. The farthest extent of standing water under the applicable conditions that determine the electrical
682.1 Scope. This article applies to the installation of
electrical wiring for, and equipment in and adjacent to,
natural or artificially made bodies of water not covered
by other articles in this Code, such as but not limited to
aeration ponds, fish farm ponds, storm retention
basins, treatment ponds, irrigation (channels) facilities.
682.2 Definitions.
Artificially Made Bodies of Water. 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. Water depths may vary seasonally or be controlled.
Electrical Datum Plane. The electrical datum plane as used in this article is defined as follows:
(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.
(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.
(3) In land areas subject to flooding, the electrical datum plane based on (1) or (2) above is a horizontal plane 600 mm (2 ft) above the point identified as the prevailing high water mark or an equivalent benchmark based on seasonal or storm- driven flooding from the authority having jurisdiction.
(4) The electrical datum plane for floating structures and landing stages that are (1) installed to permit rise and fall response to water level, without lateral movement, and (2) that are so equipped that they can rise to the datum plane established for (1) or (2) above, is a horizontal plane 750 mm (30 in.) above the water level at the floating structure or landing stage and a minimum of 300 mm (12 in.) above the level of the deck.
Equipotential Plane. An area where wire mesh or other conductive elements are on, embedded in, or placed
datum plane for the specified body of water.
682.3 Other Articles. Wiring and equipment in or adjacent to natural or artificially made bodies of water shall comply with the applicable provisions of other articles of this Code, except as modified by this article. If the water is subject to boat traffic, the wiring shall comply with 555.13(B).
