In Figure 303.05, the grounded conductor is shown at Point:

In electrical diagrams, particularly when dealing with grounded conductors, it's crucial to understand the specific points of reference indicated in the figure. In Figure 303.05, Point IV is designated as the point where the grounded conductor is situated.

The grounded conductor serves an essential function in electrical systems by providing a safe path for electrical currents to return to the ground in the event of a fault. This connection helps protect both personnel and equipment from potential electrical hazards. Identifying the grounded conductor's location is vital for ensuring proper circuit function and safety.

Points II, III, and I would represent alternative connections or components in the electrical system, but they do not fulfill the role of the grounded conductor as clearly indicated at Point IV. Understanding the specific function of each point in the diagram allows for the correct interpretation of electrical systems and adherence to safety standards.
