Safety precautions for rural lighting ready boards in Africa

Improper use of lighting ready boards in rural Africa has increased the failure rate of lighting ready boards. It is recommended that you choose high-quality circuit breakers, which can not only reduce losses, but also reduce the heat accumulated in the ready boards and extend the service life of the equipment. In addition, the safety margin of some equipment should be appropriately increased. Because the ambient temperature inside the lighting ready board is relatively high, the excess current carrying capacity of the wires should be increased by one specification; Without changing the rated current of the circuit breaker, the probability of its base burning out will be reduced by appropriately amplifying the current of the circuit breaker. Improper installation process may cause overheating and burning of the connector. Some electricians do not press the wire nose when replacing the lead, but use multiple stranded wires to wrap the wire nose and screw it, resulting in the lead burning out shortly after replacing the wire. Some manufacturers produce lighting ready boards with overlapping distribution lines and screw connections on the bus, which leads to poor heat dissipation and natural fault formation when the load is heavy. When adding new loads, it is necessary to consider whether the added current exceeds the rated current of the circuit breaker controlling the circuit. When exceeding the limit, it is necessary to replace it with a circuit breaker of the corresponding capacity. Before replacing the circuit breaker, cut off the power and fix it firmly after replacement.
