The mechanical performance testing of rural lighting electrical Ready Board Box in Africa focuses on simulating outdoor extensive use scenarios, verifying flexibility, durability, and protection reliability through repeated opening and closing of doors and operation of switches. The steps are as follows:

Door opening and closing test: manually open and close the door at a constant speed 500 times, check that the hinges and locks are not deformed, loose, or stuck; The sealing strip has no detachment or cracking, and the seal is tight after closure; The opening and closing torque of the door is uniform and there is no abnormal noise.

Switch operation test: Perform 1000 opening and closing cycles on circuit breakers, isolating switches, etc., with operating force meeting design requirements and no jamming or misoperation; Good contact between contacts, without erosion or oxidation; Mechanical interlocking is reliable and prevents misoperation.

Structural and fastener inspection: After testing, check that the box body is not deformed and the welds are not cracked; The bolts and nuts are not loose or corroded; The grounding connection is firm to ensure grounding continuity.

Severe environment simulation: Combined with the high temperature and sandstorm environment in Africa, the box can be placed in a 55 ℃ environment for 2 hours before testing, and then mechanical testing can be conducted to verify the stability of mechanical performance under high temperature.

Judgment criteria: After testing, all components function normally without damage or jamming, fasteners are not loose, and the protection level is not reduced, which is considered qualified.
