Attention shall be paid to the installation and inspection of electric meter box (small power distribution unit) conductor

The meter box (small power distribution unit) has the advantages of good electrical performance, chemical corrosion resistance, low thermal conductivity and small expansion coefficient. Today, let's talk about the knowledge of wire installation and inspection. What points should we pay attention to?

1. The current carrying capacity of the conductor section shall comply with the standard;

2. When connecting the main circuit elements with insulated wires, the common standard C Crimping terminal and phase sequence color code must meet the requirements;

3. The wiring shall comply with the requirements of the process documents, be neat, beautiful, firm and reliable;

4. The insulated conductor shall not be laid on the conductive parts, and the metal components shall be protected;

5. There shall be no joint between the connecting wires between two electrical components;

6. Electrical clearance and creepage distance: electrical clearance shall be ≮ 5.5mm and creepage distance shall be ≮ 6.3mm.
