Brief discussion on wiring matters of wiring terminal

Generally speaking, according to whether there are terminals for wires below 6mm2, non terminal external wiring and terminal external wiring shall be applied respectively. For wires with large section above 10mm2, welded copper terminals and copper terminals shall be applied.

1、 Terminal block How to calculate the number.

Each distribution box shall be calculated separately according to the section, one wire and one terminal, and the number of wires in different sections of all distribution boxes shall be counted, that is, the total number of terminals. In addition, at present, c45n switches are mostly used in finished distribution boxes, which can not press the wiring terminal. Therefore, terminal less wiring shall be applied for less than 6mm2, and welding wire terminal shall be used for more than 10mm2.

2、 Terminal block How to wire.

All kinds of electrical equipment are used in family life. The power supply must be connected in the use of electrical equipment, so indoor wiring must be carried out when setting up the house.

First, remove the wire insulation for 6 ~ 8mm and insert the exposed wire Terminal block , tighten the screw at the upper end with a screwdriver and pull it several times by hand to determine whether the wire falls off. After the wire is firmly connected with the wiring terminal, press the switch and the light is on, the wiring is successful.

3、 Terminal block Wiring precautions.

1) During wiring, the power supply must be cut off for operation, and live operation is not allowed. If you don't know whether the power supply is disconnected, you can check it with a pen and multimeter. When wiring, if the terminal post or switch terminal has a sliding button, it must be replaced immediately. Otherwise, it is easy to cause electric shock hazard.

2) When entering the power supply, please remember to install PVC conduit. If it is a wire installed on the ceiling, do not pull the wire at will. In addition, during the installation process, please set a bracket at the corner of the pipe to better fix the wire pipe. Do not place the wire on the bracket or keel without any fixing measures.

3) When installing wires, please note that the wire length of the switch box should not be too long. After wiring, please send the wire into the pipe. Do not insert the wire into the switch for fixation. In addition, the host shall not be installed under the fixed socket, otherwise the safety of household appliances will be affected.
