What type of receptacle is required in outdoor locations according to the electrical code?

The requirement for a GFCI (Ground Fault Circuit Interrupter) receptacle in outdoor locations is rooted in the need to enhance safety due to the increased risk of electrical shock in wet or damp environments. GFCI receptacles are designed to quickly cut off power if they detect a ground fault, meaning that they can prevent potential electrocutions caused by water exposure or other similar hazards. This makes them crucial for any outdoor application where moisture is present, such as patios, pools, and gardens.

While damp-rated and weather-resistant receptacles provide some level of protection against environmental factors, they do not offer the same level of safety against ground faults as GFCI receptacles do. Standard receptacles lack the necessary mechanisms to protect against ground faults, making them unsuitable for outdoor use. Therefore, in compliance with the electrical code, a GFCI receptacle is mandated for outdoor locations to prioritize safety and minimize risks associated with outdoor electrical systems.
