What constitutes a violation of NEC Article 680?

Using improper bonding or failing to use GFCI protection in designated zones indeed constitutes a violation of NEC Article 680. This article specifically addresses the requirements for the safe installation and use of electrical equipment in swimming pools, fountains, and similar installations.

One of the critical safety measures outlined in Article 680 is the proper bonding of conductive parts, which helps mitigate the risk of electric shock in wet environments. If bonding is not properly done, it can create a situation where fault currents are not safely directed to ground, leading to potential hazards. Additionally, the use of Ground Fault Circuit Interrupters (GFCIs) is mandated in certain areas surrounding pools and hot tubs to protect against electrical shock. Failing to install GFCI protection in these designated zones further exacerbates safety risks.

Choosing this option highlights the importance of adhering to these safety standards formulated to protect both people and property in environments where electrical equipment is used in close proximity to water. Thus, improper bonding and the absence of GFCI protection directly violate the safeguards put in place by NEC Article 680.
