How many GFCI receptacles must be installed outdoors in a one-family or two-family dwelling?

In a one-family or two-family dwelling, the National Electrical Code (NEC) requires that at least two Ground Fault Circuit Interrupter (GFCI) receptacles be installed outdoors. This requirement is primarily aimed at enhancing safety in outdoor environments where moisture and wet conditions can increase the risk of electric shock.

The provision for multiple GFCI receptacles ensures that homeowners have adequate access to electrical outlets for outdoor appliances, tools, and lighting while maintaining protection against ground faults. The NEC specifies that these receptacles must be readily accessible and located in areas where they can effectively safeguard users from electrical hazards, which often necessitates more than one GFCI outlet to meet functional needs in numerous outdoor spaces, such as patios, backyards, and driveways.

The requirement for two GFCI outlets also addresses the need for convenience and practicality, allowing for multiple devices to be used simultaneously without compromising safety standards. Thus, ensuring compliance with this NEC guideline is essential for promoting both utility and safety in residential settings.
