1, electrical cabinet wiring should be horizontal and vertical, firmly configured and evenly distributed, and should be vertically arranged when changing the wiring direction.

2. The secondary circuit should be far away from the arc extinguishing element and cannot affect the operation of other electrical components.

3. The secondary return route cannot pass between buses, and the connection and arrangement of lines should be firm, reliable, neat and beautiful.

4. There should be no joint in the middle of the secondary circuit connecting line, and the connecting joint can only be on the terminal or terminal row of the component.

5. The stripping length of hard wire should not be too long, about10 mm. After two wires are connected, the wire connection part should be fixed with heat shrinkable tube.

6. The terminal of each electrical component is allowed to connect two wires at most. Usually, only one connecting wire is allowed to be connected to each terminal. If two wires must be connected, the joint must be solid and reliable.

7. The cold-pressed end connection should be added to the connection of multi-lead wires, and the single-strand weak current circuit wires with cross-sectional area less than 1m_ should be connected by welding or other suitable means.

8. The flexible wire should be inserted into the terminal after being pressed by the nose. The copper core can't be exposed and pressed. When the conductor is connected to the terminal, the insulation layer of the conductor and the exposed copper should not be squeezed.

9. Both ends of the insulated wire should be covered with coding sets, and the terminals from one end to the other end must be connected with wires, and there can be no joints in the middle.

10, be careful when wiring, so as not to damage the insulation of wire core and conductor.

1 1. When there is friction between the conductor and the cabinet metal, rubber gasket should be added to protect the cable.

12, wear gloves when installing copper bars to prevent electrostatic reaction.

13, the installation height of wires in the same horizontal plane should be consistent and cannot cross. If crossing is needed, the wires should be led out at the terminal, crossed horizontally and overhead, and the route must be reasonable.

14. When wires are connected to the panel, plastic pipes should be added or trunking should be installed. In order to prevent sharp edges from cutting the insulation layer of wires, a plastic sheath must be added to the outlet part of the electrical cabinet.
