Where can the code reference for GFCI protection of receptacles in commercial garages be found?

The reference for GFCI (Ground Fault Circuit Interrupter) protection of receptacles in commercial garages is found in Section 511.12 of the National Electrical Code (NEC). This section specifically addresses the requirements for GFCI protection in parking garages, which includes both enclosed and open structures where conditions may present a heightened risk of electrical shock due to the presence of water and conductive materials.

In commercial garages, the application of GFCI protection helps enhance safety by minimizing the potential for electrical faults that could lead to shock or electrocution. The NEC delineates how and where GFCI protection is required to ensure that electrical installations in areas potentially susceptible to moisture are adequately safeguarded.

The other sections mentioned, while they provide guidelines on GFCI protection, pertain to different contexts such as dwelling units and other premises. For instance, Section 210.8(A)(6) refers to outdoor receptacles, and Section 210.8(A)(2) addresses receptacles in bathrooms. Therefore, for commercial garages specifically, Section 511.12 is the precise code location for ensuring proper GFCI protection.
