Ventilation design: The small power distribution unit needs to have good ventilation design to prevent internal overheating, but the vents should have a waterproof structure, such as a rain cover, to prevent direct entry of rainwater. In order to further improve the waterproof performance of the outdoor electrical distribution box, the manufacturer will also equip it with a special rain cover. Types of Distribution Box Waterproof Enclosures 1. Sealed. Enclosure rain hoods and drip shields are essential accessories for protecting electrical enclosures from moisture, precipitation, and water runoff in outdoor and harsh indoor environments. This guide primarily analyzes structural engineering characteristics. Common ones include IP54, IP65, etc. IP54 means dustproof and can prevent the entry of splashing water, and IP65 means completely dustproof and can prevent the entry of low-pressure water jets.
