The correct answer, which specifies a minimum distance of 3 feet for a Ground Fault Circuit Interrupter (GFCI) circuit from a shower stall, is based on established electrical safety standards. This distance is critical to ensure safety in wet areas, as water poses a significant risk of electrical shock. By maintaining this 3-foot distance, the likelihood of accidental contact with the electrical source while using the shower or being in close proximity to water is greatly reduced. This regulation is designed to protect individuals from potential injuries that could arise from electrical faults in high-moisture environments. The 3-foot requirement also aligns with the National Electrical Code (NEC), which sets guidelines for safe electrical installations. Adhering to this distance is part of ensuring that homes are equipped with safe electrical systems, particularly in areas prone to moisture, such as bathrooms. The other distances mentioned may not provide sufficient safety margins, as they could allow for situations where someone could inadvertently come into contact with water and electrical systems simultaneously, increasing the risk of shock. Thus, confirming a minimum distance of 3 feet from a shower stall ensures compliance with safety standards and protects individuals in residential settings.
