The layout of the inlet and outlet of rural lighting electrical ready boards in Africa is aimed at avoiding cable crossings, facilitating later wiring, maintenance, and upkeep, while adapting to the low regularity of rural power grid lines and the dusty environment. The layout should follow the principles of "clear zoning, clear direction, and convenient operation", combined with reasonable planning of the box structure, to ensure electrical safety and ease of use.

Priority should be given to selecting the top center or upper side position of the box for the layout of the inlet, and separate zones are required. Considering that most rural incoming lines are overhead lines, top incoming lines can reduce cable bending and avoid crossing with outgoing lines; A protective sleeve should be installed at the inlet to prevent dust and mosquitoes from entering, and sufficient cable allowance should be reserved for easy adjustment during wiring. After entering, the cable should be directly connected to the incoming terminal block in the electrical ready board, clearly separated from the outgoing area, and avoid crossing from the source.

The layout of the outlet corresponds to the setting of the inlet, with priority given to the bottom or both sides of the lower part of the box, arranged according to the zoning of the electrical circuit. The outgoing lines of rural lighting electrical ready boards are mainly used for lighting and small electrical circuits for each household. The outgoing ports can be divided into left, right, or bottom front and rear zones, with each zone corresponding to a set of circuits. The distance between the outgoing ports is reserved at 2-3cm for separate wiring. The outgoing port should correspond to the incoming port vertically, so that the cable direction is unified as "upward and downward", avoiding horizontal crossing and entanglement of cables.

Please note that the inlet and outlet ports should avoid the operation area of the cabinet door lock and terminal block to prevent the operation points from being obstructed during wiring; The outlet should be equipped with wire clips to fix the cable routing and avoid cable loosening and crossing disorder. At the same time, the layout needs to take into account the later expansion needs of rural areas, reserve 1-2 spare outlet ports, and follow the principle of "clear zoning, upper and lower outlets, and corresponding circuits" as a whole. This can completely avoid cable crossing, simplify the wiring process, and adapt to the usage scenarios and maintenance needs of African rural areas.
