What is the primary consequence of not correctly grounding an electrical system?

The primary consequence of not correctly grounding an electrical system is the risk of electrical shock and equipment damage. Grounding is essential for safety as it provides a path for electric current to flow safely to the ground in the event of a fault, such as a short circuit. Without proper grounding, individuals may come into contact with live electrical parts, leading to potential injuries or fatal shocks. Additionally, ungrounded systems increase the likelihood of equipment failure because electrical surges can damage sensitive components, leading to costly repairs or replacements.

In contrast, options related to energy efficiency, voltage regulation, and system longevity are not direct consequences of grounding issues. Grounding primarily focuses on safety and protection rather than improving operational factors like efficiency or regulation.
