What does EGC stand for in electrical terminology?

EGC stands for Equipment Grounding Conductor. In electrical systems, the Equipment Grounding Conductor is crucial for safety as it provides a path for fault current to flow safely to the ground in the event of a fault. This helps to prevent electric shock hazards and ensures that any metallic parts of electrical equipment and devices do not become energized, which could pose a serious risk to users.

The Equipment Grounding Conductor is typically made of copper or aluminum and is connected to the grounding system of a building. It is important for maintaining the integrity of the overall grounding system, helping to protect both people and equipment from electrical faults. This terminology is standardized within electrical codes, emphasizing its importance in installation and compliance practices.
