Reber Grounding Assembly NOT IN USE TECHNICAL NOTES: • 680.26 Equipotential Bonding' (Summarized) (A) Performance: The equipotential bonding required by this section shall be installed to reduce voltage gradients in the pool area. (B) Bonded Parts: The parts specified in 680.26(B)(1) through (B)(7) shall be bonded together using solid copper conductors,insulated covered, or bare, not smaller than 8 AWG or with I metal conduit of bmss or other identified corrosion -resistant metal.Connections to bonded parts shall be made in accordance with 251 An 8 AWG or larger solid copper bonding conductor provided to roduce voltage gradients in the pool area shall not be required to be extended or attached to remote panel boards, service equipment, or electrodes. (1) Conductive Pool Shells: Bonding to conductive pool shells shall be provided as specified in 680.26(B)(1)(a) or (B)(1)(b).Poured concrete, pneumatically applied or sprayed concrete, and concrete block with painted or plastered coatings shall all be considerod conductive materials due to water permeability and porosity. Vinyl liners and fiberglass composite shells shall be considered to be non conductive materials. (a) Structural Rehm arcking Steel: UnRancapsulated structurel reinforcing steel shall be bonded together by steel tie wires orthe equivalent. Where structural reinforcing steel is encapsulated in a non conductive compound, a copper conductor grid shall be installed in accordance with 680.26(B)(1)(b). (b) Copper Conductor Grid: (4). A copper conductor grid shall be provided and shall comply with(b)(1) through(b)(4). (1) Be constructed of minimum 8 AWG bare solid copper conductors bonded to each other at all points of crossing. The bonding shall be in accordance with 250.8 or approved means. (2) Conform to the contour of the pool. (3) Be aranged in a 300 mm (12 in.) by 300 mm (12 in.) network of conductors in a uniformly spaced perpendicular grid pattem with a tolerance of 100 mm (4 in.). (4) Be secured within or under the pool no more than 150 ram (6 in.) from the outer contour of the pool shell. (2) Permeter Surfaces: The perimeter surface shall extend for 1 in (3 ft.) horizontally beyond the inside walls of the pool and shall include unpaved surfaces as well as poured concrete surfaces and other types of paving. Perimeter surfaces less than 1 in (3 ft.) separated by a permanent wall or building 1.5 in (5 ft.) in height or more shall require equipotential bonding on the pool side of the permanent wall a building. Bantling to perimeter surfaces shall be provided as specified in 680.26(B)(2)(a) or (2)(b) and shall be attached to the pool reinforcing steel or copper conductor grid at a minimum of four (4) points uniformly spaced around the perimeter of the pool. For non conductive pool shells, bonding at four points shall not be required. (a) Structural Reinforcing Steel. Structural reinforcing steel shall be bonded in accordance with 680.26(B)(1)(a). (b) Alternate Means. Where structural minfoming steel is not available or is encapsulated in a non conductive compound, a copper conducror(s) shall be utilized where the following requirements are met: (1) At least one minimum 8 AWG bare solid capper conductor shall be provided. (2) The conductors shall follow the contour of the perimeter surface. (3) Only listed splices shall be permitted. (4) The required conductor shall be 450 to 600 ram (18 in. to 24 in.) from the inside walls of the pool. (5) The required conductor shall be secured within or under the perimeter surface 100 to 150 ram (4 in. to 6 in.) below the sub -grade. (3) Metallic Components: All metallic pads of the pool structure, including reinforcing metal not addressed in 680.26(B)(1)(a),shall be banded. Where reinforcing steel is encapsulated with a non conductive compound, the reinforcing steel shall not be required to be bonded. (4) Underwater Lighting. (5) Metal Fittings. (6) Electrical Equipment. (7) Fixed Metal Parts: All fixed metal parts shall be bonded including, but not limited to, metal -sheathed cables and raceways,metal piping, metal awnings, metal fences, and metal door and window frames. Exception No 1: Those separated from the pool by a permanent barrier that prevents contact by a person shall not be required to be bonded. Exception No 2: Those greater than 1.5 in (5 ft.) horizontally from the inside walls of the pool shall not be required to be bonded. Exception No 3: Those greater than 3.7 m (12 ft.) measured vertically above the maximum water level of the pool, or as measured vertically above any observation stands, towers, or platforms, or any diving structures, shall not be required to be bonded. (C) Pool Water. Where none of the bonded parts is in direct connection with the Not water, the Not water shall be in direct contact with an approved corrosion -resistant conductive surface that exposes not less than 5800 mm2 (9 in.2) of surface area to the pool water at all times. The conductive surface shall be located where it is not exposed to physical damage or dislodgement during usual pool activties,and it shall be bonded in accordance with 61 250.E Connection of Grounding and Bonding Equipri (A) Permitted Methods: Equipment grounding conductors, grounding electrodes conductors, and bonding jumpers shall be connected by one or more of the following means: (1) Listed pressure connectors (2) Terminal bare (3) Pressure connectors listed as grounding and bonding equipment (4) Exothermic welding process (5) Machine screw -type fasteners that engage not less than We threads or are secured with a nut. (6) Thread -forming machine screws that engage not less than We threads in the enclosure (7) Connections that are pad of a listed assembly (8)Other listed means (B) Methods Not Permitted: Connection devices orfittings that depend soley on solder shall not be used.
