What does the term "grounding" refer to in electrical systems?

The term "grounding" in electrical systems primarily refers to creating a conductive path that allows electrical fault currents to flow safely into the ground. This is crucial for protecting both people and equipment from the dangers associated with electrical faults, such as short circuits or lightning strikes. Grounding ensures that in the event of a fault, the excess current has a designated pathway to dissipate, which helps to prevent electric shocks, fires, and damage to electrical devices. By connecting electrical systems to the earth, grounding stabilizes voltage levels and provides a reference point for electrical circuits, contributing to overall system safety and reliability.
