Which area defines the shell of a splash pad for bonding purposes?

The correct answer focuses on the extent of the footing and collection basin area as it defines the shell of a splash pad for bonding purposes. In terms of bonding and grounding electrical installations, the NEC emphasizes the importance of effectively reducing the risk of electrical shock in areas where water is present, especially in recreational facilities like splash pads.

The footing and collection basin area represent the structural components that support the splash pad and contain the water, both crucial for ensuring that any electrical system is properly bonded to prevent shock hazards. This bonding extends beyond just the visible surface area of the splash pad, which may not include essential components that could lead to dangerous electrical potentials in case of a fault.

By requiring bonding to include the footing and collection basin area, the NEC ensures a more comprehensive safety measure, considering both the areas directly involved in water containment and the structural integrity supporting the recreational splash pad. This thorough approach aligns with the NEC's goal of safeguarding participants in these dynamic and potentially hazardous environments.
