Analysis of issues related to lighting distribution boxes

When grounding the lighting distribution box, if it is not manufactured according to standards, and if some distribution boxes lack professional grounding or neutral busbars, the leakage protection action current time may be too long. The insulation resistance of the feeder and secondary circuit does not meet the requirements, and there is no grounding wire connection between the door and frame, or between the box body and grounding terminal, without any markings. Due to a lack of safety awareness, this can easily lead to tripping, short circuits, or even disasters such as fires. Additionally, some distribution boxes do not have backup circuits, which puts the safe use of lighting distribution boxes at unavoidable risk.
