Technical requirements for installation of lighting electrical ready boards in rural Africa

First、 Inspection of Lighting electrical ready boards in African Rural Areas

1. The box body of rural lighting electrical ready boards in Africa should be made of fire-resistant materials.

2. The switch action inside the box should be flexible and reliable.

3. Neutral conductor (N) and protective grounding conductor (PE) busbars should be installed separately inside the box.

Second、 Installation requirements for rural lighting electrical ready boards in Africa

1. The box should be installed firmly, in the correct position, with complete components. The installation height should meet the design requirements, and the allowable deviation of verticality should not exceed 1.5 ‰.

2. The opening of the box should be compatible with the diameter of the conduit, and the cover of the lighting electrical ready board should be tightly attached to the wall.

3. The circuit numbers inside the box should be complete and the identification should be correct.

4. African rural lighting electrical ready boards should not be placed directly below water pipes.

Third、 Wiring requirements for lighting electrical ready boards in rural Africa

1. The wiring inside the lighting electrical ready board in rural Africa should be neat and free of twisting.

2. The wire connection should be tight, not damage the wire core, and continuous. The cross-sectional area of the wire pressed on both sides of the screw under the washer should be the same. The number of wire connections on the same electrical device terminal should not exceed 2, and the anti loosening washer and other parts should be complete.

3. The same terminal on the busbar should not be connected to N or PE wires of different circuits.

Forth、 Installation Requirements for Surge Protective Devices (SPD)

1. The model specifications and installation layout of surge protectors (SPDs) in rural lighting electrical ready boards in Africa should meet the design requirements.

2. The wiring form of SPD should meet the design requirements, and the position of the grounding wire should not be close to the outlet position. The connecting wire of SPD should be straight, short enough, and not greater than 0.5m.
