General requirements of the building's outdoor metal doors and windows, equipment shell, distribution box, etc., are required to do a second potential connection,It has not seen the specific technical requirements, we can use the past construction experience, building floor steel ring, Liang Gangjin, reinforced connecting line, equipment shell available 6 mm galvanized welded steel garden.
Equipotential bonding is the connection of metal and conductive parts exposed to electric devices and other devices in the building, artificial or natural grounding bodies, in order to reduce the potential difference, called equipotential bonding. Equipotential bonding is divided into total equipotential bonding, local equipotential bonding and auxiliary equipotential bonding.
In the local area of the building, a secondary potential connection shall be made according to the requirements of the total equipotential bonding.The LEB terminal board, that is, equipotential bonding terminal box, is mainly used to protect people from electric shock and fire caused by electricity.
