Final answer:
All receptacles within 6 feet of a pool must be GFCI protected for safety reasons, to prevent electrical shocks near water. GFCI outlets quickly disconnect when current imbalances are detected, significantly improving safety.
Step-by-step explanation:
The question pertains to the required safety standards for electrical installations near swimming pools, specifically the need for ground fault circuit interrupter (GFCI) protection. The main answer to the student's question is that all receptacles within 6 feet of the pool must be GFCI protected. This requirement is in place to prevent electrical shock hazards in wet areas, which can be potentially lethal.GFCI outlets are designed to quickly respond to changes in the magnetic field produced by current-carrying conductors. They disconnect the circuit when an imbalance is detected, significantly improving safety around water-prone areas. While the detailed operation of GFCIs and circuit breakers is covered later in textbooks, it is essential for students to understand their importance in safety applications like those in pool areas.In conclusion, it is crucial to ensure all receptacles near pools have GFCI protection to mitigate the risk of electrical shock, thereby adhering to safety codes and protecting equipment and people from potential electrical hazards.
