What type of receptacles require GFCI protection in commercial repair garages?

The requirement for GFCI (Ground Fault Circuit Interrupter) protection in commercial repair garages is primarily driven by safety standards aimed at preventing electrical shock in areas where moisture and conductive materials may be present. In this context, certain types of receptacles need GFCI protection to ensure that any ground fault or leakage current is quickly detected and interrupted.

The most pertinent option reflects the types of receptacles that commonly operate in environments where electricians would face increased risk due to wet conditions or exposure to conductive materials, which is why 125-volt, single-phase, 15- and 20-ampere receptacles are specifically called out for GFCI protection. These receptacles are widely used in repair garages for tools and equipment, highlighting their significance in safety measures.

Providing GFCI protection is essential for receptacles that supply power to appliances and machinery in repair garages, as these are high-risk areas where water may be present. The other choices, such as 250-volt configurations, refer to more specialized equipment which may not require the same level of GFCI protection as standard power tools and devices do in such environments. Hence, GFCI protection is particularly critical for the safety of users in environments with readily accessible, lower voltage recept
