A grounding sheet, also known as an equipment grounding conductor, is a conducting material that creates an electrically safe path. It ensures any stray voltages or currents are directed safely to ground, rather than through another unintended path like a person. Grounding sheets are typically made of copper, though aluminum and other conductive materials can also be used. https://timessquarereporter.com/business/grounding-sheets--ensuring-electrical-safety-and-system-stability
