GFCI protection for receptacles is required within what distance of a sink in a dwelling unit?

GFCI protection (Ground Fault Circuit Interrupter) for receptacles is necessary within 6 feet of the edge of a sink to ensure safety in areas where water and electricity may come into contact, reducing the risk of electrical shock. The answer indicating "All of the above" correctly implies that GFCI protection is required at various distances from the sink, including at 1 foot, 3 feet, and 5 feet. This reflects the principle that GFCI outlets should be readily accessible for safety concerns, accommodating different designs of kitchens or bathrooms where sink placement may vary. Thus, the requirement is not limited to a single distance, establishing a range of acceptable distances where GFCI protection must be implemented.
