How far must GFCI receptacles be located from the inside walls of the pool?

The correct distance for GFCI (Ground Fault Circuit Interrupter) receptacles from the inside walls of a pool is 10 feet, 6 inches. This standard is crucial for ensuring safety in areas where electrical equipment is in proximity to water, as it helps prevent electric shock hazards. GFCI devices are designed to cut off electrical power when they detect an imbalance in currents, and their strategic placement at this distance minimizes the risk of accidental contact with electrical sources while in or near the water.

Being 10 feet, 6 inches away from the pool walls allows for a safety buffer that adheres to National Electrical Code (NEC) requirements, which dictate how and where electrical systems should be designed and installed in relation to bodies of water, such as swimming pools. Compliance with these regulations is essential for maintaining safety standards and protecting individuals using the pool area from potential electrical shocks.

Other distances provided in the options do not meet the established safety standards and would not provide adequate protection against electrical hazards in a pool environment.
