Grounding
Grounding is a fundamental safety practice in electrical work that creates a safe path for electricity to flow into the earth. Think of it like a safety net that protects people and equipment from electrical accidents. When electrical professionals mention "grounding" or "earthing" (another common term), they're talking about connecting electrical systems to the ground to prevent shock hazards and protect equipment. This is similar to how a lightning rod guides dangerous lightning safely into the ground. It's a crucial skill in electrical engineering, and most electrical codes and safety regulations require proper grounding.
