1. Correct selection of sealing grade

The level of IP protection is a very important factor in choosing a waterproof junction box. According to IEC-60529, the first number of IP (ingress protection) level is the ability of the shell to resist the invasion of solid particles, while the second number represents the protection capability of the shell against water droplets. The IP grade of the waterproof junction box reaches IP67, which means that it can adapt to the harsh environment.

      The IP grade is only defined for the shell, but the equipment should also meet the corresponding requirements after installation, that is, if the waterproof junction box needs to be installed with cable waterproof joint, its protection level should be higher than that of the box (the mainstream waterproof cable joints in the market can reach the IP68 standard).
