In other than dwelling units, GFCI protection shall be provided for all 15A and 20A, 125V, single-phase receptacles installed within how many feet from the top inside edge of the bowl of a sink?

GFCI (Ground Fault Circuit Interrupter) protection is critical in wet areas to prevent electrical shock hazards, particularly in locations near sinks where water and electricity could come into contact. For installations in locations other than dwelling units, the requirement is that all 15A and 20A, 125V, single-phase receptacles must have GFCI protection if they are installed within a specified distance from the top inside edge of the bowl of a sink.

The correct distance for requiring GFCI protection in these situations is 6 feet. This regulation ensures that any receptacles that could be used in areas where water splashes or spills may occur are safeguarded against ground faults, thus enhancing safety for users. By providing this protection within 6 feet, any risk associated with the proximity of electrical devices to potentially wet environments is significantly reduced, addressing electrical safety requirements effectively.

Understanding this distance is crucial for compliance with the National Electrical Code (NEC) and ensures that electrical installations are safe and reliable in environments where water is frequently present.
