Why the enclosure of the distribution box leaks electricity

The leakage of the distribution box shell may occur in the following situations:

Insulation damage: The enclosure of the distribution box is usually made of insulating materials. If the insulation material is aged, damaged or damaged, the insulation between the enclosure and the live part will fail, resulting in leakage.

Design or manufacturing defects: If there are defects in the design or manufacture of the distribution box, such as unqualified insulating materials, loose installation, poor wiring, etc., the insulation between the shell and the live parts of the current will not be reliable enough, resulting in leakage.

Humidity and environmental factors: If the distribution box is in a humid or high-humidity environment for a long time, it may cause moisture absorption, aging or corrosion of the insulating material, which will affect the insulation performance of the shell and cause leakage problems.

Improper use or maintenance: If the distribution box is improperly used, maintained or repaired during use, such as using inappropriate tools or materials, replacing parts without authorization, etc., it may cause damage to the enclosure or decrease in insulation performance, which may cause leakage .

In order to avoid the leakage problem of the distribution box shell, the insulation status of the distribution box should be checked regularly to ensure that the insulation material is intact, and professionals should be invited to carry out installation, maintenance and repair work.
