Additionally, electrical components such as circuit breakers and contactors in the power distribution box must have reliable breaking capacity and short-circuit protection capabilities to ensure rapid power切断 (power cutoff) in case of circuit faults and protect equipment and personnel safety.  

- **Protection Level**: Due to the complex construction site environment, power distribution boxes should have a high protection level, such as IP54 or higher, to prevent dust ingress and water splashes from causing electrical failures.  

 Appearance and Structural Requirements for Power Distribution Boxes  

- **Appearance**: The power distribution box should have a clean and aesthetic appearance, with no obvious scratches, deformation, or other defects. The color is generally gray or black to coordinate with the surrounding environment and facilitate heat dissipation.  

- **Structure**: The structure of the power distribution box should be reasonable for easy installation, maintenance, and repair. Modular design is generally adopted, with clear layouts of internal electrical components for easy operation and replacement. Meanwhile, the power distribution box must have a good grounding system to ensure the safety of personnel and equipment.  

Export Considerations  

- **Packaging**: The packaging of power distribution boxes should be sturdy and moisture-proof to prevent damage during transportation. Wooden cases or cartons are generally used, with cushioning materials such as foam plastic inside for fixation to ensure the power distribution boxes do not shake or collide during transportation.  

- **Transportation**: Due to the long distance from China to Saudi Arabia, sea transportation is generally used for power distribution boxes. During transportation, attention must be paid to preventing seawater erosion and high-temperature effects, while ensuring the safety and timely arrival of goods.  

- **Customs Clearance**: Power distribution boxes exported to Saudi Arabia require relevant customs clearance documents, such as commercial invoices, packing lists, bills of lading, and SASO certification certificates. During customs clearance, strict compliance with Saudi Arabian customs regulations is necessary to ensure smooth clearance of goods.
