The brakes in the Ip65 Box Electrical Distribution Box should be marked with the name of the circuit. If the brakes are closed by mistake, accidents are prone to occur. The route system diagram must be affixed to the door of the distribution box, and the circuit name should be marked on the gate, especially if there are exchange, DC or different levels of power in the distribution box, there should be a clear sign. It brings convenience and safety to the work of users and maintenance personnel.
The detachable metal plate in the outdoor Ip65 Box Electrical Distribution Box is equipped with various electrical accessories, and the maintenance ground wire is not connected, which is likely to cause electric shock accidents. The detachable metal plate in the lighting distribution box should have reliable grounding maintenance. Therefore, it is requested that the metal plate should be provided with a non-removable special grounding screw, and the maintenance ground wire should be effectively connected to it. The wire diameter of the maintenance ground wire should be configured in accordance with the specifications and standards to ensure safe use.
When the ambient temperature affects the electrical components, the electrical components in the Ip65 Box Electrical Distribution Box are composed of fuses, exchange contactors, residual current action maintainers, capacitors, and meters. In fact, these originals have their working environment parameters: the upper limit of the ambient air temperature does not exceed 40°C; the average value of the surrounding air temperature for 24 hours does not exceed 35°C; the lower limit of the ambient air temperature is not less than -5°C or -25°C. The distribution box of the rural power grid is operated outdoors. It is not only exposed to direct sunlight to generate high temperature, but also generates heat during operation. Therefore, in the high summer season, the temperature inside the box will reach above 60°C. The temperature greatly exceeds the ambient temperature specified by these electrical appliances, so faults caused by overheating of electrical components in the distribution box will occur.
