What exactly does isopotential play in the construction industry Why do you have to weld isopotentia

Equipotential bonding in construction connects the exposed metal and conductive parts of electrical and other devices in the building with conductors for artificial or natural grounding bodies to reduce potential differences.

The total equipotential bonding acts on the whole building, which can reduce the contact voltage of indirect contact shock and the potential difference between different metal parts in the building to a certain extent, and eliminate the danger of dangerous fault voltage introduced from the external electrical lines and various metal pipes outside the building.

After the total equipotential connection of the residential building, it can prevent the conduction of PE and PEN lines in the power line of the TN system from introducing fault voltages and causing electric shock accidents, and at the same time, it can reduce the probability of potential difference, arc and electric spark, and avoid electrical fire accidents and personal electric shock accidents caused by grounding faults. At the same time, it is also necessary for lightning protection.

Function: It is to connect all the metal structures (steel bars, metal frames, metal pipes, etc.) inside the whole building together to form equal potentials, so that the potentials of all points in the room are equal when leakage, so that there will be no current generation (no potential difference).

Local equipotential bonding in the bathroom can help reduce potential differences and ensure personal safety.

Equipotential design is designed to prevent the generation of static electricity and protect the human body from electric shock. In particular, the toilet must be equipped with equipotential coupling to prevent electric shock during showering. I don't know if you have this experience, sometimes we will feel numb when we go to the bathroom to wash our hands, which is caused by the fact that the building does not do equipotential bonding.

Toilet equipotential, it is to connect all electrical appliances in the bathroom to form a Faraday cage, even if an electrical leakage and grounding is invalid, it can also eliminate the potential difference (voltage) between different metal parts, so that people will not be in danger. You must know that in a humid environment, the safe voltage is very low.

Just think about it for yourself and you'll understand the truth. The bird has two legs, standing on a bare wire, and the reason why it is not shocked is because the potential of the left foot is equal to the potential of the right foot, so no current will pass through the bird's body, so it is safe.
