Common problems of lighting distribution box
The quality problem of the lighting distribution box itself:
When grounding the lighting distribution box, it was not manufactured in accordance with the standard. If there is no professional standard earth or neutral bus in some distribution boxes, the leakage protection action current time is too long, the insulation resistance of the feeder line and the secondary circuit does not meet the requirements, and there is no grounding connection between the terminals of the door, the frame and the box, no marking. Because there is no awareness of safety, it is particularly easy to cause disasters such as trips, short circuits, and even fires. Or some distribution boxes do not have a backup circuit, so that the safe use of lighting distribution boxes is at the unavoidable risk.
Reason analysis: The main factor leading to the quality problem of the distribution box is the human factor, followed by the material factor. In order to obtain more profits, some real estate companies provide some unqualified products to reduce engineering costs. At the same time, some supervision units and construction units are the two in one, turning a blind eye to product quality supervision, leading to the use of substandard products in the project. Some construction teams are not qualified. Because of certain relationships, authorized by Party A or Party B at will, privately select and provide low-priced accessories and distribution boxes, resulting in serious hidden dangers in their quality.
