The rural environment in Africa is hot, humid, dusty, and often accompanied by rainstorm and pest in rainy season. The lighting electrical Ready Board Box needs to be checked regularly according to the grading cycle+standardized steps to prevent leakage, short circuit and fire risks.

1、 Inspection cycle (adapted to the environment) Daily inspection (once a week): Quick inspection of appearance and surrounding environment. Monthly inspection (once a month): Basic function and sealing protection inspection. Quarterly inspection (once every 3 months): component fastening and insulation testing. Annual maintenance (once a year, mandatory before the rainy season): comprehensive inspection and maintenance.  

2、 Inspection steps (power-off operation, safety first) 1 Appearance and sealing: The box has no deformation or cracking; The door seal is intact and the door lock is effective; The inlet is tightly sealed with no signs of water leakage. two Internal cleaning: Remove dust, spider webs, and insect nests to prevent short circuits. three Wiring and fastening: The terminals are not loose, burnt black, or oxidized; The insulation layer of the wire is intact without aging or damage. four Protection device: The circuit breaker/leakage switch operates flexibly and can be opened and closed normally; Test the leakage protection tripping function (once a month). five Grounding and insulation: reliable grounding, grounding resistance ≤ 4 Ω; Measure the insulation resistance with a megohmmeter to be ≥ 0.5M Ω Surrounding environment: There is no accumulation of debris around the box, good ventilation, and it is far away from water sources and direct sunlight.  

3、 Key reminder: Annual maintenance must be completed before the rainy season, and moisture-proof sealing must be strengthened; If any abnormality is found, immediately cut off the power and stop using it. Contact professional personnel for maintenance and prohibit unlicensed operation.
