What is the purpose of grounding an electrical system?

• A. Preventing power surges
• B. To keep exposed metal from becoming electrically charged
• C. Enhancing electrical efficiency
• D. Reducing electromagnetic interference

Answer: (B)

Grounding an electrical system serves several important functions, with one of the primary purposes being to ensure safety by preventing exposed metal components from becoming electrically charged. When an electrical system is properly grounded, it provides a safe path for electrical current to flow in the event of a fault, such as a short circuit. This minimizes the risk of electric shock, fire, or damage to equipment by directing excess current away from people and conductive surfaces, which should not carry electricity under normal conditions. While other functions, such as reducing electromagnetic interference, preventing power surges, or enhancing electrical efficiency, may be associated with electrical systems, they do not specifically address the critical safety aspect that grounding provides. Grounding directly protects individuals and equipment from undue risks that could arise from electrical faults, making it an essential practice in electrical safety.
