For GFCI protection, receptacles at what rated voltage within the vicinity of a fountain must abide by Electrical Code requirements?

The correct answer regarding the rated voltage for GFCI protection for receptacles in the vicinity of a fountain aligns with the requirements set forth in the National Electrical Code (NEC). Specifically, the NEC mandates that receptacles operating at voltages from 125V through 250V must have GFCI protection in wet locations like those near fountains.

This range is significant because it covers most standard outlet configurations used in residential and commercial settings, particularly those installations that might interact with water. The purpose of GFCI (Ground Fault Circuit Interrupter) devices is to prevent electrical shock, which is particularly critical in areas where water is present, like fountains. By ensuring that the receptacles within this voltage range are protected by GFCIs, it enhances safety and compliance with the NEC standards regarding electrical systems in wet locations.

The other options fall outside this specific range, either being too narrow or not including the common voltage ratings critical for such installations. Therefore, focusing on the range of 125V through 250V captures the essential aspect of GFCI requirements effectively.
