Failure caused by improper selection of electrical appliances in [lighting distribution box]
The lighting distribution box operates outdoors. It is not only exposed to direct sunlight, but also generates heat during operation. Therefore, in hot summer, the temperature in the box will reach 60 ° C or higher. The ambient temperature specified by these devices can cause failure due to overheating of electrical components in the distribution box.
The lighting distribution box is not suitable for selecting AC contactor capacity during manufacturing. For different socket circuits, AC contactors with the same capacity are installed, and part of the contactor current cannot be obtained without considering the imbalance of three-phase load. This level is based on the normal selection model and the current level selection is made, which causes the AC contactor to burn out in the high temperature season in summer.
