Where is the equipotential bonded MEB mounted?

First of all, look at what you build, then look at your grounding trunk line from the first lead, and finally see that you want to do the equipment waiting for the position in that position, according to the actual situation to position, there are no strict requirements, for intelligent buildings, you can be inside the electrical shaft. Thank you.

Installed in toilets, power distribution rooms, strong and weak electric wells and other places that need grounding protection. The equipotential box is installed, and the lower skin is located from the ground.

First of all, according to the size of the outer diameter of the pipe, select the corresponding specifications of the special hoop (the inner diameter of the hoop is equal to the outer diameter of the pipe), the material of the hoop should be galvanized flat steel or copper strip, and the thickness meets the strength requirements.

Then put the hoop on the pipeline, and the ruler is firmly connected with the equipotential coupling line through the corresponding specifications of the screw, the lingfu nut and the spring washer, and the contact surface between the hoop and the pipe should be scraped clean during installation.

After the construction is completed, the continuity of the conductivity should be tested, and the defective conductivity should be repaired in time. Metal pipe connections generally do not need to be connected with jumper wires. The water meter of the water supply system should be connected with jumper wires to ensure the effective equipotential connection and grounding of the water pipe; The metal protective sleeve of the metal pipe should be cross-connected with the metal pipe.

Huatian Century equipotential has a terminal that is directly connected to the steel bar of the building, and then this steel bar is directly connected to the outdoor grounding bus! You don't need to connect to the outdoor grounding busbar.

Decoration Da Cui explained the toilet equipotential connection, hoping to help you in decoration.

Equipotential

bonding, bonding): Separate devices and conductive objects are connected with equipotential connecting conductors or surge protection devices to reduce the potential difference between lightning currents.

GB50057-94 Definition of Peer Potential Connection.

The separate equipment and conductive objects are connected with equipotential connecting conductors or surge protectors to reduce the potential difference between lightning currents. ”

gb50343-2004

Definition. Electrical connection of the potential of the leakage conductive part of the equipment and the basic phase of the concealment cover. ”

GB50054-95 definitions.

An electrical connection that makes the conductive part of each exposed conductor and the conductive part outside the device have basically equal potential. ”

In order to ensure the safety of electricity and prevent the introduction of high potential into the human body and the harm of electrical equipment, it is necessary to equipotential connect the shell of all electrical equipment and the steel bars of the building.

In the actual installation, the neutral line is connected with the reserved terminal of the steel bar at the power supply inlet line and is called repeated grounding. The lead-out wire is called a protection wire (PE line), so as long as it is wired correctly according to the single-phase three-wire system, it should be able to ensure that the equipotential connection can be achieved. Don't worry about it. Socks.
