Giải thích
Section 680.12 requires the disconnecting means for pool equipment to be readily accessible, within sight of the equipment, and located at least 5 feet horizontally from the inside walls of the pool unless separated by a permanent barrier. The 5-foot spacing keeps a person from reaching the disconnect while in the water.
