(A) All metallic conduit, piping systems, pool reinforcing steel, lighting fixtures, and the like, shall be bonded together and grounded to a common ground. The metal parts of ladders, diving boards, and their supports, shall be grounded.
(B) No pool equipment shall be grounded to an external grounding electrode that is not common to the pool ground (deck box or transformer enclosure).
(C) Metal wiring enclosures shall be grounded in accordance with Article 250, National Electrical Code, 1968 Edition, in addition to other requirements of this chapter.
(D) An unbroken wire of no smaller than #10 flexible, green in color, shall be used for grounding off deck boxes, steel reinforcements, and all other grounded equipment to the distribution panel ground, as required in this section.
(E) Metallic raceways shall not be depended upon for grounding. Where exposed to pool water, and in other corrosive areas, such as in pump houses or adjacent to water treating and other equipment, the grounding of the noncurrent carrying parts shall be by means of an insulated copper conductor sized in accordance with §§ 250-295, of the National Electrical Code, 1968 Edition.
(F) In addition to the other requirements of this section, lighting fixtures that are supplied by flexible cord or cable shall have all metal parts grounded by means of an insulated grounding conductor that is an integral part of the cord. This conductor shall be No. 14 AWG or larger.
(G) Nonelectrical equipment required to be grounded to a common ground in accordance with this section shall be grounded in accordance with Article 250, National Electrical Code. Structural reinforcing steel may be used as a common bonding conductor for nonelectrical parts, where connections can reliably be made in accordance with the provisions of Article 250, of the National Electrical Code, 1968 Edition.
