If the Ready Boards with Bulkhead Light fails, it shall be handled in time. Generally speaking, only knowing the cause of failure can fundamentally solve the problem. According to the analysis of the Ready Boards with Bulkhead Light manufacturer, there are several main reasons for the failure of the Ready Boards with Bulkhead Light: the center of the Ready Boards with Bulkhead Light mounted on the wall is 1.3m from the ground (the height of the box is 0.8m higher than the sky) or 1.5m (the height of the box is less than 0.8m).

1. Faults caused by improper selection of electrical appliances in the Ready Boards with Bulkhead Light: due to improper selection of circuit breaker current in the manufacturing process, circuit breakers with the same current are installed in different socket circuits, and the imbalance of three-phase load is not considered. However, it is not possible to increase the current level selection based on the normal selection model based on the partial outlet contact current level.

2. Environmental temperature impact caused by low-voltage apparatus: it is composed of low-voltage apparatus in the Ready Boards with Bulkhead Light, residual current operated protector and miniature circuit breaker. The upper limit of ambient air temperature shall not exceed 40 ℃; The average ambient air temperature in 24 hours shall not exceed 35 ℃; The lower limit of ambient air temperature shall not be lower than - 5 ° C or - 25 ° C.

In hot summer, the temperature inside the box will reach 60 ° C or higher, and the temperature at this time will greatly exceed the specified ambient temperature of these electrical appliances. When the height of the Ready Boards with Bulkhead Light is less than 500mm, it shall not exceed 1.5mm. When the height of the Ready Boards with Bulkhead Light is greater than 500mm, it shall not exceed 3mm. The pipe shall be straight and the exposed length shall be less than 5mm..

3. Faults caused by product quality: due to the large number of Ready Boards with Bulkhead Lights required and the short construction period, the Ready Boards with Bulkhead Light manufacturers urgently need the supply time of low-voltage electrical appliances, and the large quantity, resulting in product quality. The demand is not strict, leading to the failure of some products soon after they are put into use.
