1. When the ready 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 a "head allowance" of about 5mm. For smaller ready boards, wood bricks can also be embedded at the installation place (according to the position of the installation holes at the four corners of the ready board or distribution board), and then use wood screws to fix the ready board or distribution board at the wood bricks.

2. The ready 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 ready 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.

3. For the spiral fuse installed in the ready 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.

4. The AC, DC or power supplies with different voltage levels in the ready board shall have obvious signs. In the lighting ready board, the busbar of zero line (N line) and protective zero line (PE line) shall be set respectively. The zero line and protective zero line shall be connected on the busbar without splicing and shall be numbered.

5. 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 ready board must be reliably grounded (connected to neutral).

The above is the introduction of the connection method of the household ready board. Only after we know the connection method of the household ready board can we install and connect the household ready board well, and can obtain the power supply and use it well. We also don't have to worry about the damage caused by the wrong connection of the household ready board.
