Based on the current situation of electricity consumption in rural households in Africa, future new demand, and electricity safety regulations, the number of reserved circuits in the lighting electrical ready board in rural Africa should be at least 4, which can meet the current basic lighting and commonly used small appliances, as well as adapt to the electricity demand of future new equipment, balancing practicality and foresight.

The current electricity consumption of rural households in Africa is mainly based on basic lighting, while gradually popularizing small household appliances such as energy-saving light bulbs, mobile phone chargers, small electric fans, simple rice cookers, etc. In the future, with the improvement of living standards, it is highly likely that new equipment such as televisions, small refrigerators, and electric water kettles will be added, and circuit reservations need to fully consider this incremental demand.

The specific circuit allocation suggestions are as follows: 2 basic lighting circuits, respectively controlling the main indoor areas (bedroom, living room, kitchen) and outdoor courtyard, corridor lighting, to avoid single circuit failure causing the whole house to lose light; There are 2 ordinary socket circuits, one for commonly used small appliances in living rooms, bedrooms, and other areas, and the other for kitchens and bathrooms (with waterproof protection). Separate control can reduce the impact of electrical failures; Two backup circuits are specifically designed for future additions of lighting or small appliances, such as bedroom lighting, small appliance sockets, etc., without the need to modify the original circuit layout, reducing the cost of later renovations.

The core reason for reserving 6 circuits is that although the electricity load of rural households in Africa is relatively low, the dispersed layout of circuits can reduce the risk of line overload and short circuit, while also adapting to the incremental demand for household electricity. If the reserved circuits are insufficient, new equipment in the later stage will need to be connected privately, which can easily cause safety hazards such as electrical fires and electric shocks. In addition, considering the insufficient power supply stability in some rural areas of Africa, reasonable circuit reservation can also facilitate fault diagnosis and maintenance, improve electricity safety and convenience, and fully meet the actual electricity consumption scenarios and long-term needs of rural households.
