Which of the following is a requirement for electrical installations near water?

Installing electrical systems near water presents particular hazards that necessitate specific protective measures to ensure safety. Ground fault circuit interrupters (GFCIs) are designed specifically to prevent electric shock in wet environments. When a ground fault occurs, such as when electricity finds an unintended path to the ground—often through water—a GFCI cuts off the electrical supply, reducing the risk of injury. This is especially critical in areas like bathrooms, kitchens, and outdoor locations where water exposure is commonplace.

While waterproof connections are important for minimizing exposure to moisture, and other options like overhead wiring might reduce certain risks, they do not offer the same level of protection against electric shock that GFCIs provide. High-voltage cables can be dangerous near water and are not relevant to safety practices in this context, making GFCIs the most appropriate choice to safeguard individuals from potential electrical hazards in moisture-prone areas.
