What type of electrical receptacles must be used within 36 inches of a water source?

GFI (Ground Fault Interrupter) receptacles are specifically designed to protect against electrical shock in areas where water is present. The presence of water increases the risk of electrical shock, making GFI receptacles the appropriate choice for locations near water sources, such as bathrooms, kitchens, and outdoor settings.

These receptacles continuously monitor the flow of electricity and disconnect the power if they detect any imbalance, which occurs when electricity flows through an unintended path, like through water or a person. This safety feature is crucial in preventing serious injuries in environments where moisture is prevalent.

In contrast, standard receptacles do not provide this level of protection and may pose a serious risk if used in such locations. Grounded receptacles are necessary for safety in general, but they alone do not include the added safety mechanisms of GFI circuitry. High-voltage receptacles are designed for specific equipment that requires higher electrical input and are not relevant to safety concerns around water sources. Therefore, GFI receptacles are mandated to reduce electrical hazards in proximity to water.
