Emergency response measures for lighting electrical ready boards in rural Africa without professional personnel

When a rural lighting electrical ready board box in Africa malfunctions and there are no professional maintenance personnel present, the primary operation is to immediately disconnect the main switch and completely cut off the incoming power supply. This is the core first step in curbing the spread of faults, preventing electric shock and electrical fires.

After the power is cut off, let it stand for a few minutes and wait for the residual electricity in the circuit capacitor to be released. It is strictly prohibited to open the cover or touch the internal components with electricity to avoid leakage and arc burns. Subsequently, visually inspect the box for obvious fault symptoms such as cracking, burning odor, aging and peeling of the circuit, loose and heating of the wiring terminals, and frequent tripping of the leakage protector. Only conduct visual inspection and do not disassemble the internal circuit breaker, SPD, and wiring terminals without authorization.

If it is only a local branch lighting failure, the corresponding branch switch can be turned off, the faulty branch can be isolated, and other normal lighting circuits can be retained to ensure basic household electricity supply. It is strictly prohibited to short-circuit the leakage protector without authorization, cancel the grounding protection, replace the fuse with copper wire, and replace large-sized circuit breakers at will to prevent safety accidents caused by overload, lightning strikes, or leakage.

During the malfunction period, it is strictly prohibited to operate the electrical ready board with wet hands and keep away from the box to stack flammable materials such as straw and firewood. Ensure proper on-site fencing and warning, prohibit the elderly and children from approaching and touching, record the fault symptoms and wait for professional personnel to go to the countryside for inspection. Do not blindly disassemble and repair the equipment to avoid personal electric shock, fire, and permanent equipment damage.
