Which receptacles must be GFCI protected?

GFCI (Ground Fault Circuit Interrupter) protection is crucial where water and electricity may come into contact, increasing the risk of shock. In residential and recreational vehicle contexts, it is required to have GFCI protection for all exterior receptacles, as these are often exposed to moisture and potential water sources, such as rain or splashing from garden hoses.

Additionally, kitchen receptacles must be GFCI protected because kitchens are high-risk areas, with sinks and dishwashers that may contribute to accidental water exposure. The same logic applies to bathroom outlets, where water usage is frequent, increasing the likelihood of electrical shock from wet hands or splashed water.

Therefore, the answer encompassing all exterior, kitchen, and bathroom receptacles reflects the safety standards intended to minimize hazards related to electrical shock in environments where moisture is present.
