Requirements For Installation Of Distribution Box

Our lives have long been inseparable from the use of electricity. While using various electrical appliances, distribution boxes have also appeared in our lives. As the basic infrastructure of the power system, we must always pay attention to safety and standardize operations in the installation and application of distribution boxes.

High And Low Voltage Distribution Cabinets The installation requirement is to use non-combustible materials. In production plants and offices with low risk of electric shock, open distribution boxes can be installed; in workshops with high risk of electric shock or poor working environment, such as casting, forging, heat treatment, boiler room, woodworking room, etc., closed cabinets should be installed; in dangerous workplaces with conductive dust or flammable and explosive gases, closed or explosion-proof electrical facilities must be installed. The electrical components, instruments, switches and lines of the distribution box should be arranged neatly, installed firmly and easy to operate. The bottom surface of the floor-mounted distribution box should be 5~10mm above the ground; the center height of the operating handle is generally 1.2~1.5m; there are no obstacles within 0.8~1.2m in front of the distribution box, and the protection line connection is reliable; no bare live bodies should be exposed outside the distribution box; electrical components that must be installed on the surface of the distribution box or on the distribution board must have reliable shielding.
