Which of the following describes the bonding method for pool electrical equipment?

The correct answer is based on the National Electrical Code (NEC) requirements for bonding pool electrical equipment, specifically stating that bonding should be performed using solid copper conductors, which can be either insulated or bare. This method is favored because copper exhibits excellent conductivity and resistance to corrosion, making it reliable for providing continuous grounding and bonding necessary for safety in wet environments, such as around swimming pools.

Using solid copper conductors ensures that any electrical faults can be effectively grounded, minimizing the risk of electric shock or equipment damage. Insulated conductors may be used to provide additional protection against corrosion, while bare conductors allow for easy connection and conductivity.

In contrast, temporary bonding methods or non-conductive materials like aluminum are not considered safe or compliant with NEC requirements for permanent installations. Covered conductors, while useful in some applications, do not fulfill the specific NEC bonding requirements as effectively as copper conductors do for pool equipment, which necessitates connections that are both reliable and enduring in wet conditions.
