Grounding
Grounding (also called earthing in some countries) is a fundamental safety practice in electrical work. It's like creating a safe path for electricity to flow into the earth if something goes wrong, protecting people and equipment from electrical shocks. Think of it as a safety net that diverts dangerous electrical currents away from people and sensitive equipment. When someone lists grounding experience on their resume, they're indicating they know how to make electrical installations safe and compliant with safety codes.
