What grounding methods are allowed around pools according to NEC Article 680?

The permissible grounding methods around pools according to NEC Article 680 primarily include the use of equipment grounding conductors and grounding rods. This is because outdoor pools, due to water, associated metal structures, and the presence of electrical equipment, require robust grounding methods to ensure safety from electrical shocks.

Equipment grounding conductors are essential as they provide a path for electrical faults, ensuring that any stray current is safely redirected to the ground, thereby minimizing the risk of electric shock to individuals who may come into contact with the pool or nearby structures. Grounding rods also enhance the overall grounding system by providing a low-resistance path to the earth, which is critical in preventing electrical hazards in wet environments.

While bonding jumpers and insulation barriers are components of grounding strategies, they focus more on connecting metal parts to ensure that they maintain the same electrical potential, rather than serving as primary grounding methods. Grounding mats and water grounding methods are not standard practices under NEC for ensuring safety around pools, which underscores the importance of utilizing equipment grounding conductors and grounding rods for optimal protection.
