The use of terminals for the outgoing terminals of rural lighting electrical ready boards in Africa follows the principle of "safety first, standardized adaptation", combined with local power supply stability, maintenance conditions, and lighting load characteristics. The conclusion is clear: it is strictly prohibited for different circuits to share terminal blocks, and each outgoing terminal must use independent wiring terminals. The neutral wire (N) and protective wire (PE) must be separately equipped with dedicated neutral blocks to ensure electrical safety and convenient operation and maintenance.

According to international general electrical specifications and practical requirements, independent terminal blocks are the foundation for ensuring safety. The General Specification for Electrical and Intelligent Systems clearly stipulates that the PE wires of each circuit must be connected independently, and it is strictly prohibited to share terminals to avoid affecting the grounding protection of other circuits during single circuit faults or maintenance, and to prevent the risk of chain failure. Distributed lighting is commonly used in rural areas of Africa. Although the number of circuits is not large, sharing terminals can easily lead to loose and poor contact of wires, causing heating and short circuits. In addition, there are many thunderstorms in the local area, and the failure of grounding protection can exacerbate the risk of electric shock.

The terminal block can be shared, but it must meet the premise of "separate circuit independent wiring". Terminal blocks are only used as wiring carriers and should be divided into wiring positions according to circuits. On the same terminal block, the phase and neutral wires of different circuits should be connected to independent terminals. The number of wires connected to the same terminal should not exceed 2, and the wire diameter should be consistent. This method can save box space, reduce costs, and meet the simplified needs of lighting electrical ready boards in rural Africa. At the same time, it is easy to distinguish circuits and reduce maintenance difficulties in the later stage.

Based on the actual situation in rural Africa, the selection of independent terminals also needs to be adapted to local conditions: choose copper terminals that are resistant to oxidation and moisture, suitable for the dusty and humid environment in rural areas; The terminal specifications should match the wire diameter to avoid loose crimping of the wire due to the terminal being too small. Overall, sharing terminal blocks is feasible, but each outgoing terminal must use independent wiring terminals, strictly distinguishing between phase lines, N lines, and PE lines. This not only meets regulatory requirements but also adapts to local operation and maintenance levels, ensuring stable and safe operation of the lighting system from a detailed perspective.
