Which of the following is NOT a purpose of grounding and bonding?

Grounding and bonding are crucial safety measures in electrical systems. The primary purposes include stabilizing voltages, preventing electrical shock hazards, and protecting equipment from surges. Option D relates to enhancing the aesthetic appeal of electrical installations, which does not align with the established functions of grounding and bonding.

Grounding serves to provide a pathway for excess electricity, which stabilizes voltage levels, particularly concerning underground conductors, ensuring that the electrical system remains within safe operational limits. Additionally, by creating a direct connection to the earth, grounding minimizes the risk of electrical shock to individuals, as it enables a safe route for fault currents. Furthermore, bonding connects various conductive parts to ensure a continuous electrical path, which also contributes to shock protection and helps in effectively managing surges, protecting sensitive equipment from potential damage.

In summary, while options A, B, and C address vital safety and functional roles of grounding and bonding, enhancing aesthetic appeal does not pertain to these essential electrical safety practices.
