IP rating is a protection level standard developed by the International Electrotechnical Commission, which uses two numbers to represent the equipment's ability to protect against solid foreign objects and water. For the selection of indoor lighting electrical ready boards in rural Africa, it is necessary to consider the local environmental characteristics and electricity demand, and comprehensively consider the IP level, installation environment, core parameters, structural form, and core components.

The indoor environment in rural Africa is complex and may have issues such as dust, moisture, and even insects and ants. Therefore, the selection of IP rating for lighting electrical ready boards is crucial. Generally speaking, indoor dry environments can choose IP30 or IP40 levels, which can prevent solid foreign objects with a diameter of 2.5mm or 1.0mm or more from entering. If there is dust or occasional water droplets splashing indoors, such as in areas like kitchens and bathrooms, it is recommended to choose an IP54 rating, which can effectively prevent dust and prevent water splashing from all directions from entering.

In terms of installation environment, it is necessary to evaluate the indoor humidity, dust situation, and installation space. If space is limited, wall mounted lighting electrical ready boards can be chosen for easy installation and space saving; If pursuing beauty and cleanliness, and reserving wall holes in advance, embedded lighting electrical ready boards are a better choice.

In terms of core parameters, the number of circuits needs to be calculated based on the number of rooms and functional areas. Each room should have at least one lighting and one socket, with separate circuits for the kitchen and bathroom. Meanwhile, estimate the total incoming current based on the total power and select the appropriate circuit breaker.

In terms of structural form, small wall mounted lighting electrical ready boards can be selected for those with fewer circuits and lower currents; If there are multiple circuits and high currents, a larger box size should be selected and sufficient wiring space should be reserved.

In terms of core components, it is recommended to use small circuit breakers with C-type trip curves for lighting circuits, and RCBO leakage protectors for socket circuits to ensure electrical safety.
