What is one key difference between bonding and grounding?

Bonding and grounding are critical concepts in marine electrical systems, each serving distinct but related purposes in enhancing safety and functionality. The correct answer highlights that bonding involves connecting all metal parts on a vessel, creating a uniform electrical potential among them. This practice minimizes the risk of stray currents and ensures that if there is a fault, the electrical current will have a safe path to follow, thereby reducing the potential for electric shock or equipment damage.

Grounding, on the other hand, refers specifically to connecting a system or equipment to the earth. This provides a reference point for the electrical system and directs excess electrical energy safely into the ground in case of a fault, thus protecting both the equipment and personnel.

By distinguishing bonding from grounding, the correct answer emphasizes that bonding is about interconnecting the metal components, while grounding is concerned with a direct connection to the earth. This understanding is vital for anyone working in marine electrical systems, as it lays the foundation for safe installation and maintenance practices.
