Do outdoor areas require GFCI protection for 125-volt, single-phase, 15 and 20 ampere general purpose receptacles?

Outdoor areas do indeed require GFCI (Ground Fault Circuit Interrupter) protection for 125-volt, single-phase, 15 and 20 ampere general-purpose receptacles. This requirement is in place due to the increased risk of electrical shock in wet environments, as outdoor areas can be exposed to rain, moisture, and other conditions that heighten the potential for electrical hazards. The National Electrical Code (NEC) mandates that any outdoor receptacle must be GFCI-protected to ensure safety for users who may come into contact with water and electrical sources simultaneously. This level of protection is essential for preventing serious accidents or fatalities associated with ground faults.

Other options reflect misunderstandings about the necessity of GFCI protection across different scenarios. GFCI protection is not limited to commercial buildings; it applies universally to residential installations as well. Additionally, there is no seasonal restriction for GFCI requirements; they must be installed regardless of weather conditions, including winter.
