GFCI protection is required for all receptacles in commercial repair garages that use electrical diagnostic equipment, electrical hand tools, or portable lighting with respect to which receptacle configurations?

• A. II only
• B. I & III only
• C. I, II, & III
• D. I only

Answer: (C)

GFCI protection in this context is about protecting people from electrical shock by quickly disconnecting power when a fault current leaks to ground. In commercial repair garages, the environment often involves moisture, oils, and conductive surfaces, and portable tools, diagnostic equipment, and portable lighting are used close to the floor or near these hazards. Because of these conditions, any receptacle that serves those tools and lighting must have GFCI protection, regardless of how the receptacle is installed or configured (wall-mounted, floor-mounted, or other types). So all configurations used for diagnostic equipment, hand tools, or portable lighting in the garage require GFCI protection. The protection trips when there’s any leakage, typically within milliseconds, reducing the risk of shock.
