For bonding, the contour of the copper ring must maintain what distance from the inside wall of the pool?

The requirement that the contour of the copper ring used for bonding must maintain a distance of 18 inches to 24 inches from the inside wall of the pool is crucial for safety and effectiveness. This distance helps ensure that the bonding connection is adequately positioned to minimize the potential for electrical shock due to stray current.

The specified distance provides sufficient separation to effectively diminish the risk of unintended contact with any conductive surfaces, which can occur if the bonding ring is too close to the pool wall. Additionally, adhering to this standard distance complies with the National Electrical Code (NEC) guidelines, aimed at protecting individuals from electrical hazards in and around swimming pools. By maintaining this specified range, the installation enhances safety and promotes proper grounding, ensuring that any stray currents are safely directed away from the pool area.
