A grounding device consists of a grounding electrode (plate), a grounding busbar (indoor or outdoor), a grounding down conductor (grounding jumper wire), and a frame ground. It is used to connect the electrical system to the earth. A metal object that is in direct contact with the earth to achieve an electrical connection is a grounding electrode. It can be an artificial grounding electrode or a natural grounding electrode. The grounding electrode can be given a certain electrical function, such as system grounding, protective grounding, or signal grounding.
