Causes of overheating in the incoming cable of the distribution box
Electrical cables overheat most often because of overloading, loose connections, or damage to the cable or plug. When wires carry too much current, are not installed properly, or have poor contact at joints, excess heat builds up and can create real safety risks. Identifying these causes is the first step in prevention: Overloading: Exceeding the current rating of a cable can lead to excessive heat generation, causing insulation degradation and potential failure. According to research data, when the cable temperature exceeds the allowable value by 8°C, its service life will be reduced by more than half, and when the insulation layer temperature reaches the critical point, the risk of short circuit will increase by 300%.
