Does GFCI protection apply to all 125V receptacles installed in detached garages?

In detached garages, GFCI (Ground Fault Circuit Interrupter) protection is indeed mandatory for all 125V receptacles. This requirement is outlined in the National Electrical Code (NEC), which emphasizes electrical safety in areas that may have a higher risk of electrical shock due to moisture or water exposure. Detached garages can be exposed to such conditions, making GFCI protection essential for any 125V receptacles installed in these locations.

The NEC addresses this need for safety by mandating GFCI protection to prevent electrical shock hazards, especially in locations that are not part of the primary dwelling and can be more susceptible to dampness from environmental factors like rain, snow, or humidity. By ensuring that all 125V receptacles in detached garages are GFCI protected, the code helps to promote safe electrical practices and reduce the risk of electrical accidents.

While there are specific scenarios that require GFCI protection, such as receptacles used for certain appliances or those located in bathrooms, the key takeaway is that for detached garages, the overarching requirement is that all 125V receptacles must have GFCI protection, reinforcing the importance of adhering to electrical safety standards.
