Outlets supplying permanently installed nonsubmersible pump motors for fountains must have what kind of protection?

Outlets supplying permanently installed nonsubmersible pump motors for fountains must have GFCI or SPGFCI protection to ensure safety in wet locations. This requirement is mandated by the National Electrical Code to protect against electrical shock hazards, particularly in environments where water is present.

GFCI stands for Ground Fault Circuit Interrupter, which is specifically designed to detect imbalances in electrical current. When a ground fault is detected—indicating that electricity is flowing through an unintended path, such as through water or a person—the GFCI quickly disconnects the power, minimizing the risk of electrocution. SPGFCI stands for Special Purpose Ground Fault Circuit Interrupter, which offers additional features for specific applications, including those used with special equipment like fountain pumps.

In this context, choosing GFCI or SPGFCI protection aligns with safety protocols to mitigate electrical shock risks associated with the operation of pump motors in close proximity to water, whereas the other types of protection do not specifically address the same level of electrical hazard related to ground faults.
