What type of protection is required for receptacle outlets installed within 6 feet of a sink?

Receptacle outlets installed within 6 feet of a sink are required to have Ground Fault Circuit Interrupter (GFCI) protection due to the increased risk of electrical shock in locations where water is present. GFCI devices are designed to detect imbalances in electrical current and can quickly disconnect the power, providing an essential safety mechanism in wet areas such as kitchens and bathrooms.

The National Electrical Code (NEC) specifically mandates this type of protection in areas where electrical circuits may come into contact with water, to significantly reduce the likelihood of electrical accidents. This requirement is particularly critical in spaces where appliances and tools are used near water sources, thus reinforcing the importance of safeguarding human life while operating electrical equipment.

While receptacles can be protected in other ways, such as through fuses or surge protection, these options do not provide the same level of safeguard against electric shock in environments with high moisture. Therefore, GFCI protection is the most appropriate and effective choice in this context.
