[0002] The grounding device is also called the integrated grounding device: a device that forms an electrical connection between electrical equipment or other objects and the ground. The grounding device consists of a grounding electrode (plate), a grounding busbar (indoor or outdoor), a grounding lead (grounding jumper wire), and a frame grounding. It is used to achieve the purpose of connecting the electrical system to the earth. The metal object that is in direct contact with the earth to achieve electrical connection is the grounding electrode. It can be an artificial grounding electrode or a natural grounding electrode. This grounding electrode can be given a certain electrical function, such as system grounding, protective grounding or signal grounding. The grounding busbar is the reference potential point of the building's electrical equipment, through which the part of the electrical equipment that needs to be grounded is connected to the grounding electrode. It also plays another role, that is, it connects the equipotential bonding wires in the electrical equipment to each other, thereby achieving a total equipotential bonding between the large conductive parts in a building. The connecting wire between the grounding electrode and the grounding busbar is called the grounding electrode lead.
