All metal conduit shall be corrosion-resistant and suitable for the location. Art. 680-10.

Lighting fixtures and lighting outlets installed in the area extending between 5 feet and 10 feet horizontally from the inside walls of the pool shall be protected by a ground-fault circuit interrupter. Art. 680-22.

DEFINITION: Storable Swimming Pool or Wading Pool: A pool with a maximum dimension of 18 feet and maximum wall height of 42 inches and so constructed that it may be readily dissembled for storage or reassembled to its original integrity.
