What is the main purpose of grounding in pool electrical installations?

The main purpose of grounding in pool electrical installations is to provide a path for fault current to prevent electric shock. Grounding helps to ensure that in the event of a fault—such as a short circuit or equipment malfunction—the electrical energy is directed safely into the ground instead of through a person. This significantly reduces the risk of electrical shock or electrocution for individuals who may come into contact with water or metal components near the pool.

In addition to enhancing safety, proper grounding practices play a pivotal role in maintaining the reliability of electrical equipment used in pool installations. Grounding also serves to help protect the equipment from damage due to stray currents or lightning strikes.

The other options, while potentially relevant in different contexts, do not directly address the primary safety function provided by grounding in this specific application. For instance, providing a path for fault current is crucial to avoid any violent electrical incidents around water, which is especially dangerous.
