What safety measures are necessary for temporary electrical supplies near pools?

The requirement for temporary electrical supplies near pools to have conductors that are raised and protected from water exposure is based on the inherent risks associated with water and electricity. Water is a conductive medium, and in environments like swimming pools where moisture is prevalent, the chances of electrical shock or equipment damage increase significantly if electrical conductors are improperly positioned.

By ensuring that conductors are elevated and protected, the risk of accidental contact with water or pooling around the conductors is minimized, thereby enhancing safety for individuals using the pool area. This measure complies with NEC guidelines that prioritize safety in wet locations.

The other choices do not meet the necessary safety standards. Leaving conductors on the ground can lead to direct exposure to water, which poses a significant hazard. The presence of bare conductors would also create an extreme risk of electric shock, especially in a wet environment. Finally, while outdoor-rated cords are important for general use, they alone do not provide sufficient protection against the specific hazards present near pools without appropriate elevation and protection measures.
