What safety hazards may arise from severe heating of components in lighting electrical ready boards?

Serious safety hazards caused by heating of components in electrical ready boards

Long term high-temperature operation of internal components in electrical ready boards can cause multiple safety hazards, especially in the harsh outdoor electricity environment of rural Africa, where the risks will further intensify.

Firstly, accelerate the aging of electrical components. High temperature can damage the material structure of switches, wires, and insulation layers, causing the insulation skin of wires to soften, crack, age, and peel off, losing their insulation protection ability, and easily causing circuit leakage and short circuit faults.

Secondly, increase the risk of electric shock. After insulation damage, the box and metal parts are prone to electrification, and rural residents have weak awareness of electrical safety. When operating or touching the box in daily life, it is easy to cause personal electric shock and electric shock accidents, posing a threat to personal safety.

Thirdly, it can cause electrical fires. Overheating of components, excessive resistance at wiring points, and continuous accumulation of heat, combined with accumulated dust and debris, can easily ignite surrounding cables and flammable impurities; The arc sparks generated by a short circuit can directly trigger a fire in the box and wiring. The wiring in rural houses is messy, and the fire is prone to spread quickly.

Fourth, frequent equipment malfunctions and paralysis. High temperature can cause circuit breakers to trip incorrectly, components to burn and burn out, resulting in frequent interruptions of lighting and household electricity in the area, affecting daily power supply stability. In severe cases, it can also burn out the entire distribution equipment, increase maintenance and replacement costs, and leave long-term electrical safety hazards.
