What happens during a ground fault?

During a ground fault, current flows from an energized conductor to the ground unintentionally. This situation occurs when there is an unintended path between the electric current and the ground, typically due to insulation failure, equipment malfunction, or accidental contact with a conductive surface.

When this occurs, the current seeks the path of least resistance to the ground, potentially leading to dangerous conditions such as electric shock, fire hazards, or equipment damage. Ground fault protection devices, such as ground fault circuit interrupters (GFCIs), are designed to detect these currents and interrupt the flow to prevent harm.

This understanding highlights the importance of proper grounding and bonding practices to minimize risks associated with ground faults.
