Waterproofing of the power distribution box inlet hole
Sealing design: Waterproof sealing strips should be used at the joints of the box to ensure that no water penetrates when the box is closed. 9 Waterproofing and drainage measures should be taken for the cable mezzanines, cable trenches and cable rooms located below the outdoor floor of substations and power distribution stations ; waterproofing measures should also be taken for the cable inlets, outlets and cable protection pipes. (1) Waterproof distribution box engineered for harsh outdoor and industrial environments, providing IP65–IP68 sealing against dust, rain, and UV. (3). The inlet and outlet of weatherproof outlet box should be below the box of waterproof outdoor electrical box, not above the box of ip68 junction box. In addition, for some special interfaces. It seems like I've previously seen in the installation instructions information about installing drain holes in the bottom of the box for moisture/water to escape. Another electrician and I were talking about caulking the box and I mentioned installing drain holes. Common ones include IP54, IP65, etc. IP54 means dustproof and can prevent the.
