What is the minimum level of protection for an outdoor distribution box?

The protection level of the outdoor distribution box is as follows:

IP is the code name used internationally to determine the protection level, and the IP level is composed of two numbers.

The first number indicates dust resistance;

The second number means waterproof, and the higher the number, the better the protection.

Dustproof rating. 0 No protection No special protection.

1. Prevent the intrusion of objects larger than 50mm Prevent the human body from accidentally touching the internal parts of the lamp Prevent the intrusion of objects with a diameter greater than 50mm.

2 Prevent the intrusion of objects larger than 12mm Prevent fingers from touching the internal parts of the lamp.

3 Prevent the intrusion of larger objects Prevent the intrusion of tools, wires or objects larger in diameter.

4 Prevent the invasion of larger objects Prevent the invasion of mosquitoes, flies, insects or objects larger in diameter.

5 Dustproof It is not possible to completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the lamp.

6 Dustproof Completely prevent dust ingress.

Different environments choose different protection levels, outdoor distribution boxes.

IP54 and above are required for protection.

The public lighting of the stairwell should be PE line.

IP rating. It is the level of protection against the ingress of foreign objects in the enclosure of electrical equipment, ** is the International Electrotechnical Commission.

IEC60529, which was also adopted as the American National Standard in 2004.

IP is the code used by the international to determine the protection level, the IP level is composed of two numbers, the first number means dustproof, the second number means waterproof, the larger the number means the better the protection.

According to JGJ 242-2011 Electrical Design Code for Residential Buildings, the protection level of outdoor power supply inlet box is not less than IP54, and the protection level of waterproof power distribution can be used as a reference according to this standard.

The higher. The waterproof distribution box is very well sealed, both waterproof and dustproof, etc., and it is also acid and alkali resistant, and the protection level is very high. The box material of the waterproof distribution box is made of high-quality cold-rolled steel plate.

Electrostatic spraying treatment, fully insulated protection.

The protection level of the outdoor distribution box is IP54 and above. The public lighting in the stairwell has to add PE lines, and now they all add PE lines. View the original post

Choose the protection level according to different environments! View the original post

JGJ 242-2011 Code for Electrical Design of Residential Buildings stipulates that the protection level of outdoor power supply inlet box shall not be less than IP54, which can be used as a reference. View the original post" satisfied.

The requirements are greater than IP54, please refer to GB1498-79

The protection level of the outdoor distribution box should be at least IP54.

The lowest level is level 4, but generally speaking, it is level 7 waterproof level - [Wanken Waterproof Tester] waterproof level.

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect3: Water or rain from the corner of 60 degrees to the shell has no effect4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment of the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

Do you choose IP54 or IP65? One of the definitions of IP rating (dust and water resistance): IP65 Reference standard:

GB 4208 2008 Enclosure Protection Rating (IP**) IPXX Dust Rating (First X Representation) 0: No protection 1: Protection against large solids 2:

Protection against the intrusion of medium-sized solids 3: Prevent the ingress of small solids 4: Prevent the ingress of solids larger than 1mm 5:

Prevents harmful dust accumulation 6: Completely prevents dust ingress Waterproof rating (indicated by the second x) 0: No protection 1:

Water droplets dripping into the enclosure have no effect 2: When the enclosure is tilted to 15 degrees, water droplets dripping into the enclosure have no effect 3: Water or rain from a 60 degree corner to the enclosure has no effect 4:

Liquid splashed into the hull from any direction has no harmful effect 5: Rinsed with water without any harm 6: Can be used in the cabin environment 7:

Can withstand water immersion in a short period of time (1m) 8: Immersion in water for a long time under a certain pressure.
