An electrical ground is a safety feature in an electrical system that provides a direct path for electrical current to flow safely into the earth in case of a fault or surge. It helps prevent electric shocks, fires, and equipment damage by ensuring that excess electrical energy is safely dissipated. Grounding typically involves connecting electrical systems to a metal rod or conductor buried in the ground, and it is an essential part of the wiring in homes, buildings, and industrial systems. Proper grounding is crucial for electrical safety and code compliance.
