Generally, it is used for repeated grounding in power distribution room, and also used in toilets with bathing equipment for residents, and for grounding bathing equipment and related sockets.
Equipotential bonding junction box is suitable for electrical devices in general industrial and civil buildings, equipotential bonding to prevent indirect contact electric shock, explosion and fire caused by grounding fault, and lightning protection of buildings and electronic information. Equipment against transient overvoltage and interference, etc.
The equipotential connection terminal box connects the steel mesh in high-rise residential buildings, hospitals, swimming pools and other buildings. , PE line terminals, sockets, water pipes, heating pipes, medium gas pipes, metal basins, bath stands, shower handrails, refrigerators, air conditioners, and conductive floors in power distribution panels are connected to terminal boards in their respective equipotential connection boxes, thus forming their own equipotential bodies and protecting personal and equipment safety. ?
Is it a grounding device? Generally, there is a small rectangular iron box with a copper sheet and some nuts under the washbasin in the toilet at home. The main purpose is to connect the grounding wire on the shell of household appliances such as washing machine to it, and then connect it to the main reinforcement of the building column through the galvanized flat steel between it and the building. Once household appliances leak electricity, it will cause leakage current to flow to the earth through it to prevent human beings and their good friends from getting an electric shock. ?
Equipotential terminal box-in short, it is a device to eliminate the potential difference of distribution lines in different areas of the building that are not in one phase and prevent people from getting an electric shock.
It has no lightning protection function.
