How to choose the sealing grade of New Material Waterproof Junction Box?

 Correctly select the sealing grade
When purchasing New Material Waterproof Junction Box, the IP protection level is a very important factor.
According to IEC-regulation, IP
(Ingressprotection) The first number of the level is the shell's ability to resist the intrusion of solid particles, and the second number indicates the shell's ability to protect against water droplets.
This means that it can adapt to a more demanding environment.
The IP level is only defined for the shell, but the equipment should meet the corresponding requirements after installation. That is to say, if the New Material Waterproof Junction Box needs to be installed with a waterproof cable connector, its protection level should be higher than that of the box.
