What type of conductor must be installed from each hull inlet to the AC shore grounding connection?

The correct answer is individual. This is because each hull inlet must have a dedicated conductor running from it to the AC shore grounding connection. This ensures that there is a separate and clear path for ground continuity from each inlet, which enhances safety and reduces the risk of ground faults or electrical shock.

Using individual conductors minimizes the potential for faults in one section of the system to affect others. It also allows for easier troubleshooting and maintenance. In marine electrical installations, particularly those adhering to ABYC (American Boat and Yacht Council) standards, maintaining the integrity of the grounding system is critical for overall safety and operational reliability.

In contrast, options such as common, shared, or heavy gauge do not meet the safety requirements and best practices established for grounding in marine environments. A common or shared conductor could increase the risk of electrical interference or failure during a fault condition, adversely affecting the entire system. Heavy gauge, while it refers to size and capacity, does not directly relate to the requirement for individual connections from hull inlets to the grounding point.
