A metal fixture must be grounded if located within what distance of a kitchen sink?

The requirement for grounding a metal fixture in proximity to a kitchen sink is designed to ensure safety by preventing electrical shock. The guideline often necessitates grounding if the fixture is within a specified distance of the sink, reflecting the potential for water contact or splashing, which can increase the risk of electrical hazards.

Choosing the distance of 8 feet vertically or 5 feet horizontally is correct because it strikes a balance between safety practices and practical installation scenarios. Vertical and horizontal distances are specified separately to address various layouts or placements of sinks and fixtures, acknowledging that water can overflow or splash beyond the immediate vicinity of the sink.

This grounding requirement is typically enforced by electrical codes to protect users from potential shock hazards, especially in wet areas like kitchens. Thus, the distances stated in this correct option directly address safety concerns related to electrical installations near water sources.
