Grounding in buildings and connecting the neutral line to the distribution or control panels' grounding device is also called repeated grounding. Correct grounding of services depends upon understanding the definition and role of the grounded conductor. The neutral conductor is typically the grounded conductor connected to the system's neutral point, carrying current under normal operation. 4 (A) (1) states that grounded electrical systems “shall be connected to earth in a manner that will limit the voltage imposed by lightning, line surges, or. While there are other types of grounding like repeated grounding, lightning protection grounding, and electrostatic shielding grounding, their functions align with these two purposes.
