When is temporary electrical power allowed near pools according to NEC Article 680?

Temporary electrical power near pools is allowed during maintenance under strict supervision and must include Ground Fault Circuit Interrupter (GFCI) protection. This requirement is in place to ensure safety, as water and electricity present significant risks when combined. GFCI devices are designed to protect against electrical shock by disconnecting power when they detect an imbalance in electrical current.

During maintenance, proper supervision ensures that qualified personnel are present to monitor the situation, minimizing the risk of accidents. The presence of GFCI protection is crucial in wet environments such as those around pools, where the potential for contact with water increases the danger of electric shock. This adherence to safety protocols is emphasized in NEC Article 680.

Other options, while they may seem plausible, do not meet the overall safety requirements outlined in the NEC. For instance, having electrical power anytime regardless of conditions can lead to unsafe situations, and assumptions that temporary power can only be supplied from specific sources like portable generators overlook broader safety provisions regarding supervision and protection.
