What happens if neutral-to-ground connections are improperly implemented in a grounding system?

If neutral-to-ground connections are improperly implemented in a grounding system, it can lead to current flowing in the Equipment Grounding Conductor (EGC) circuits. This occurs because a faulty neutral-to-ground bond can introduce stray currents into the grounding system. When these stray currents are present, the EGC, which is designed to safely conduct fault currents, may carry unintended load currents. This situation can create a hazardous condition, as it might lead to voltage differences on equipment enclosures and increase the risk of electric shock.

On the other hand, enhancing electrical performance or ensuring safety in the electrical system would require proper implementation of neutral-to-ground connections. Similarly, reducing potential electrical shock is a goal that can only be achieved when these connections are correctly made, as improper bonding can introduce risks rather than mitigate them. Therefore, understanding the critical role of proper neutral-to-ground connections is essential for maintaining safety and reliability in electrical systems.
