In electrical terminology, the term “ground” refers to a conductive connection; representing “zero electrical potential”. It is the safe point of discharge of unwanted static electricity.
When something is grounded, it’s neutral; it has no charge. Connecting a conductive floor to ground ensures that static charges will be diverted to Earth through the conductive flooring system. Examples of typical grounds include: electrical conduit, building steel, copper bus bars and steel rods buried in the Earth.
