Which of the following options provides the allowed methods for GFCI protection?

GFCI (Ground Fault Circuit Interrupter) protection is crucial for electrical safety, particularly in areas exposed to moisture or where there's an increased risk of electrical shock, such as kitchens, bathrooms, and outdoor locations. The correct choice indicates that a combination of GFCI circuit breakers and GFCI-protected receptacles provides the required protection.

Using a GFCI circuit breaker protects the entire circuit downstream from the breaker, which can include multiple outlets and devices, enhancing safety throughout that circuit. On the other hand, GFCI-protected receptacles offer localized protection at each outlet but require installation for each individual receptacle. This means that if you utilize both methods, you ensure comprehensive coverage against ground faults.

Thus, the combination approach is the most effective, as it provides flexibility and meets safety requirements by ensuring that all areas where water or moisture might be present are adequately protected. Additionally, having both methods can serve as a redundancy, increasing the reliability of the electrical system.
