How to assemble the distribution board?

Every household now has one distribution board. It needs to be connected to the distribution board after decoration, or it will be involved in the progress of hydropower projects, but many people don't know much and want to know how to install the distribution board without operation? How to connect the distribution board?

How to install the distribution board?

1. Open mounted distribution board. When the distribution board is installed on the wall, it shall be fixed with split bolts (expansion bolts). The bolt length is generally the sum of the buried depth (75 ~ 150mm), the thickness of the box bottom plate, the thickness of nuts and washers, plus about 5mm "head allowance". For smaller distribution boards, wood bricks can also be embedded at the installation position (embedded according to the installation holes at the four corners of the distribution board or distribution board), and then wood screws can be used to fix the distribution board or distribution board at the wood bricks.

2. Concealed distribution board shall be installed. The distribution board shall be embedded in the wall. During wall construction, the reserved hole shall be about 20mm larger than the length and width of the distribution board. The reserved depth is the thickness of the distribution board plus the thickness of plastering on the inner wall of the hole. When embedding the distribution board, the box can be fixed by filling concrete between the box and the wall

3. The distribution board shall be installed firmly, horizontally and vertically, and the vertical deviation shall not be greater than 3mm; During concealed installation, there shall be no gap around the distribution board, the edges around the panel shall be close to the wall, and the contact part between the box and buildings and structures shall be coated with anti-corrosion paint.

4. For the spiral fuse installed in the distribution board, its power line shall be connected to the terminal of the intermediate contact, and the load line shall be connected to the threaded terminal. In this way, there will be no electric shock when loading and unloading the molten core. Porcelain plug-in fuses shall be installed vertically.

5. The AC, DC or power supplies with different voltage levels in the distribution board shall have obvious signs. The lighting distribution board shall be provided with zero line (N line) and protective zero line (PE line) bus bars respectively. The zero line and protective zero line shall be connected on the bus bar without splicing and shall be numbered.

6. When the conductor leads out of the panel, the panel wire hole shall be smooth without burr, and the metal panel shall be equipped with insulating protective sleeve. The shell of metal shell distribution board must be reliably grounded (connected to neutral).
