African rural lighting electrical ready boards comply with IEC low voltage specifications and South African SANS standards, and are intended for use by non professional villagers. The circuit breaker on/off signs are prioritized with white background and black text as the basic printing background, and the ON (closed/I) and OFF (open/O) symbols maintain high contrast. If it is an operation button type circuit breaker, the OFF button should be red, and the ON button should not be red. It can be white, gray, black, or green; The handle type miniature circuit breaker MCB generally adopts a black handle, and the I and O markings are printed in black with a white background color, which is intuitive and easy to identify.

The focus of this scenario is on high temperature exposure and sand and dust wear. It is not recommended to use stickers for identification, but to use compression molding, laser etching, or UV resistant ink printing to prevent fading and blurring. Red represents danger, power outage, and emergency disconnection in the definition of electrical safety, and is only used for OFF identification; Green represents the normal power on state and can be used for closing indication. Simultaneously equipped with IEC standard graphic symbols: I represents connected, O represents disconnected, and the text can be paired with English ON/OFF to facilitate recognition by illiterate villagers and reduce the risk of accidental electric shock.

African rural users have weak electrical knowledge, and the identification color logic of lighting electrical Ready Board Box circuit breakers must be simple and unified to avoid multi-color confusion. The entire set of identification should match the color of the cables inside the box: brown for phase lines, blue for neutral lines, and yellow green for ground lines, forming a unified color system that meets the requirements of Eskom project acceptance, enhances on-site operation and user self inspection safety, and reduces rural electricity accidents.
