What is the required condition for receptacles that are installed close to swimming pools?

The correct condition for receptacles installed close to swimming pools is that they must be GFCI protected. This requirement is crucial due to the higher risk of electric shock in wet environments. Ground Fault Circuit Interrupter (GFCI) devices are designed to detect ground faults, which occur when electricity flows through an unintended path, such as water. The GFCI will quickly cut off the power, significantly reducing the risk of serious injury or fatality caused by electric shock.

While grounding, insulation, and covering receptacles are also important aspects of electrical safety, they do not specifically address the immediate risks associated with the proximity of receptacles to water, such as in swimming pool areas. GFCI protection is particularly mandated by electrical codes, emphasizing its critical role in ensuring safety around water features.
