Outdoor weatherproof distribution boxes must withstand rain, dust, temperature fluctuations, moisture, UV rays, and on-site contaminants. Key design considerations include door fit, gaskets, locks, cable entry glands, drainage methods, base structure, and internal ventilation.

If ventilation is required for heat dissipation, its impact on the protection rating must also be evaluated. Protection cannot be judged solely by the "weatherproof" label; it must be verified through complete assembly, component installation, and test results. This article details design essentials for outdoor distribution boxes regarding sealing, cable entry, drainage, heat dissipation, and maintenance.
