The equipotential terminal is a ground connection device in the equipotential box, which connects the grounding system and the equipotential box settings to form a conductor.
The equipotential terminal is based on a standard zero potential, the same potential of the conductor on the terminal.
Application recommendations
1. Can not be sealed in the wall;
2. Can not be blocked with ceramic tiles;
3. Can not be abandoned without use.
Expanded informationRole
1. The role of the total equipotential connection is to reduce the contact voltage of the indirect contact electric shock in the building and the potential difference between the different metal parts, and to remove from outside the building through the electrical lines of the various metal piping introduced by the hazardous fault voltage hazards, the building should be done for each power supply into the total equipotential connection, the various connection terminal board should be interlocked with each other.
2. Auxiliary equipotential connection: the two conductive part of the conductor with wire directly for equipotential
Potential connection, so that the fault contact voltage down to the contact voltage limit below. Power network impedance is too fire, so that the automatic cut-off time is too long, can not meet the requirements of anti-shock; to meet the bathroom, swimming pool, hospital operating room and other places on the special requirements of anti-shock; from the TN system with the same distributor to supply the fixed and mobile two kinds of electrical equipment, and the fixed equipment protection appliance cut off the power supply time to meet the requirements of the mobile anti-shock.
3. Local equipotential: when the need to do in a local place within the scope of each auxiliary equipotential coupler, through the local equipotential coupling terminal board will be the following parts of the interconnection, in order to easily realize the local scope of multiple auxiliary equipotential coupling, known as local equipotential coupling.
