What is a disadvantage of inadequate grounding?

Inadequate grounding can lead to an increased risk of equipment damage. Grounding serves as a critical safety measure in electrical systems, helping to direct excess electricity safely into the ground. When grounding is insufficient, there is a possibility of overvoltage conditions which can result from lightning strikes or faults in the electrical system. This overvoltage can cause components to fail, leading to irreversible damage. Additionally, devices that rely on a stable electrical supply may experience erratic performance or complete failure due to electrical surges without proper grounding. Therefore, the significant disadvantage of inadequate grounding is indeed the increased risk of equipment damage in electrical systems.
