How to distribute the distribution box is reasonable?
Most modern households have distribution boxes for the safety of household electricity use. But how to distribute the distribution box is reasonable, which has become a problem that many families worry about. Today I will talk about this problem with you!
1. The screw fuse and power line installed on the distribution box should be connected to the terminal of wholesale ftth patch cord the middle contact, and the load line should be connected to the terminal of the screw. In this way, electric shock can be well avoided when unloading the fuse core. Ceramic plug fuses should be installed vertically.

2. For small distribution boxes, wood bricks can also be pre-nailed at the installation place, and then the distribution board or distribution board is fixed on the wood bricks with wood screws. The dark-assembled electric box and distribution box are built into the wall. When building the wall, a hole about 20 mm larger than the length and width of the distribution box should be left, and the thickness of the distribution box should be added to the pattern on the inner wall of the hole. When burying the distribution box, you can fill the concrete between the box and the wall to fix the box

3. When the wire comes out of the panel, the panel wire hole must be smooth and cannot be bent, and the metal panel must be installed with an insulating protective cover. The metal shell distribution box shell must have a stable ground wire.

4. When the distribution box and distribution box are installed on the wall, they should be fixed with expansion bolts. The length of the bolt usually needs to be added to the insertion depth (75~150mm), the thickness of wholesale ftth patch cord the box bottom plate, the sum of the thickness of the nut and washer, and an "excess allowance" of about 5mm.

5. The power supplies with different AC, DC or voltage levels in the distribution box must be clearly marked. The lighting distribution box should be equipped with neutral line (N line) and protection line (PE line) bus, neutral line and protection line should be connected to the bus, not entangled, with numbers.

6. The distribution box should be set firmly, horizontal and vertical, and the vertical deviation is 3 mm; it cannot exceed. For concealed installation, there should be no gaps around the distribution box, the edges around the panel should be close to the wall, and the contact parts of boxes, buildings and structures should be coated with anti-corrosion paint.
