Swimming and Wading Pools ARTICLE 680 is hereby amended to read as follows: A. GENERAL 680-1 Scope. The provisions of this Article apply to the construction and installation of electric wiring for equipment in or adjacent to all swimming and wading pools, whether permanently installed or storable and to metallic appurtenances in or within 5 feet of the pool, and to the auxiliary equip- ment, such as pumps, filters and similar equipment. No electric appliances or wiring shall be installed in the water or in enclosing walls of a swim- ming pool, except as provided in this Article. The requirements of Article 680 will add to the safety of decorative and therapeutic pools; however, additional safeguards may be necessary. 680-2 Approval of Equipment. All equipment shall be approved for the pur- ;,ose. 680 -3 Application of Other Articles. Except as modified by this Article, wiring and equipment in or adjacent to swimming pools shall comply with the applicable requirements of Chapters 1 through4 of this Code. See Section 370 -13 for junction boxes, Section 347 -3 for rigid nonmetallic conduit and Article 720 for low - voltage lighting. 680 -4 Definitions. (a) Permanently Installed Swimming or Wading Pool. One that is con- structed in the ground, on the ground, or in a building in such a manner that the pool cannot be readily disassembled for storage. (b) Storable Swimming or Wading Pool. One that is so constructed - that it may be readily disassembled for storage and reassembled to its original integrity. 7'21 (c) Forming Shell. A Metal structure designed to sup- port a wet -niche lighting fixture assembly and intended for mounting in a swimming pool structure. (d) Wet -Niche Lighting Fixture. A fixture intended for installation in a metallic forming shell mounted in a swim- ming pool structure where the fixture will be completely surrounded by pool water. (e) Dry -Niche Lighting Fixture. A fixture intended for installation in the wall of the pool in a niche which is sealed against the entry of pool water by a fixed lens. (f) Ground -Fault Circuit - Interrupter. A device whose function is to interrupt the electric circuit to the load when a fault current to ground exceeds some predetermined value that is less than that required to operate the over - current protective device of the supply circuit. 680 -5 Transformers and Ground -Fault Circuit - Interrupters. (a) Transformers. Transformers used for the supply of fixtures, together with the transformer enclosure, shall be approved for the purpose. The transformer shall be a two - winding type having a grounded metal barrier between the primary and secondary voltage windings. (b) Wiring. Conductors on the load side of a ground - fault circuit - interrupter or of a transformer, used to comply with the provisions of Section 680- 20(a)(2), shall be kept entirely independent on all other wiring and electrical equipment. 680 -6 Location and Protection of Receptacles. No outdoor receptacles on the property shall be located within 10 feet of the inside walls of the pool. All outdoor receptacles located between 10 feet and 15 feet of the inside walls of the pool shall be protected by a ground -fault circuit- interrupter.
