For which of the following is GFCI protection required?

GFCI protection is specifically required in areas where the risk of electrical shock is heightened due to the proximity of water or where moisture is present. In the case presented, a receptacle within 6 feet of a wet-bar sink presents a potential risk since it is located near a source of water, making GFCI protection essential to prevent electrical shock hazards.

This requirement aligns with electrical codes aimed at enhancing safety in wet or damp environments, thereby ensuring that any electrical failures can be quickly addressed. The use of GFCI outlets in these locations automatically cuts off power when an imbalance of current is detected, protecting individuals from potential electrocution.

In comparison, while kitchen receptacles and outdoor receptacles may have specific requirements, not all kitchen receptacles or those for decorative outdoor use have the same level of risk associated with water exposure.
