Choose different levels of protection in different environments.

The protection level of outdoor distribution boxes requires IP54 or above.

PE line should be added to public lighting in stairwell.

IP level is the protection level for foreign body intrusion in electrical equipment shell. The source is IEC 60529, which was also adopted as the national standard in 2004.

IP is the international code used to identify the protection level. IP level consists of two numbers. The first number represents dust-proof, the second number represents water-proof, and the larger the number, the better the protection.

According to JGJ 242-2011 Residential Building Electrical Design Code 6.2.5, it is stipulated that the protection level of outdoor power supply inlet box is not lower than IP54. The protection level of waterproofing and distribution can be referred to according to this standard. The higher the IP value of distribution box, the higher the waterproofing level.

The waterproof distribution box is very well sealed, waterproof and dustproof, acid and alkali resistance, and the protection level is very high. The material of waterproof distribution box is treated by electrostatic spraying of high quality cold-rolled steel plate and fully insulated protection.
