Which types of receptacles must be GFCI protected according to NEC Article 680?

According to NEC Article 680, GFCI protection is required for all 120V, 15A and 20A receptacles that are installed within 20 feet of the inside walls of a pool or spa. This requirement is established to enhance safety by minimizing the risk of electric shock in areas where water and electricity are in close proximity, as the potential for accidents increases.

Option B is correct because it accurately reflects the NEC provisions that pertain specifically to pool and spa environments. The 20-foot distance is critical because it accounts for the various activities that may occur around a water feature and aims to protect individuals who might inadvertently come into contact with a receptacle while wet or in close proximity to water.

The other options do not meet the NEC requirements for GFCI protection in the context of pools and spas. For instance, option A, which mentions a 10-foot distance, does not align with the NEC’s specifications and therefore does not provide the required level of safety. Option C discusses residential kitchens, which have different requirements regarding GFCI protection and do not specifically pertain to pool or spa installations. Option D encompasses all outdoor receptacles but lacks the specificity regarding proximity to pools or spas that is crucial per the NEC guidelines
