The appearance inspection of the PC material (polycarbonate) electric meter box should be meticulous and comprehensive. The following are specific requirements and steps:

Firstly, check the appearance of the meter box for flatness, smoothness, and no obvious scratches, cracks, deformations, or paint leaks. These defects not only affect the aesthetics of the meter box, but may also have adverse effects on its sealing and durability.

Secondly, carefully inspect the coating quality of the meter box. The coating should be firm, uniform, and free from bubbles, peeling, or color differences. A good coating can not only improve the weather resistance and corrosion resistance of the meter box, but also enhance its overall aesthetics.

In addition, the identification and nameplate of the electric meter box are also the focus of inspection. The identification should be clear and accurate, including key information such as manufacturer information, model, specifications, rated voltage and current. The nameplate should be firmly fixed on the meter box and not easily detached or damaged.

During the inspection process, special attention should also be paid to the sealing performance of the meter box. Ensure that the sealing strip is intact, free from damage or aging, to prevent moisture, dust, and other impurities from entering the interior of the meter box and affecting the normal operation and safety of the circuit.

Finally, the fixing and installation position of the meter box should also be checked. Ensure that the meter box is installed securely, without any shaking or tilting, and that the fixing screws are tightened. At the same time, the installation location of the meter box should be convenient for daily maintenance and inspection to ensure the safety of operators.

In short, the appearance inspection of PC material meter boxes should be meticulous to ensure that the meter boxes meet relevant standards and requirements in terms of appearance, coating, labeling, sealing performance, and installation position, in order to ensure their normal operation and safety of use.
