How should the grounded conductor on a high-impedance grounded neutral system be grounded?

In a high-impedance grounded neutral system, the grounding of the grounded conductor must be done in accordance with the guidelines set forth in Article 250.36. This article specifically addresses the requirements for grounding in systems that use high-impedance grounding, which is a method used to allow for the detection of ground faults while minimizing the fault current.

A high-impedance grounded system is designed to limit ground fault current to a low value, which helps to prevent equipment damage and maintain system stability. Adhering to the requirements outlined in Article 250.36 ensures that both safety and operational integrity are maintained, facilitating the proper grounding of the neutral conductor without introducing excessive fault currents.

The other articles mentioned in the options address different scenarios or grounding methods, making them less relevant for a high-impedance grounded neutral system. Therefore, the most accurate choice for grounding the grounded conductor in this specific context is the guidance provided in Article 250.36.
