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. The phenomenon of electrical wire overheating creates numerous fire and explosion risks and reflects non-compliance with technical standards in electrical systems. For electrical engineers and M&E contractors, understanding root causes helps develop effective preventive measures, ensuring project. Electrical boxes—whether found in basements, attics, or walls—are designed to safely manage your home's electricity. With the surge in electricity demand, the problem of overheating of cables has become increasingly prominent, becoming an invisible killer threatening power safety. According to research data, when the cable temperature exceeds the allowable value by 8°C, its service life will be reduced by more. Several factors contribute to cable overheating. If it is not processed in time, the consequences can be imagined. This heat generation is fundamentally governed by the relationship $P = I^2R$, where $P$ is the power (heat) generated, $I$.
