An overheating electrical cable is a serious warning sign. It may be caused by circuit overload, loose contacts, old sockets, an unsuitable breaker, or hidden wiring faults.
Cables often heat up when too many high-power appliances use one circuit or when the cable size does not match the load.
Burning smell, dark marks, warm sockets, frequent breaker trips, and flickering lights should be checked immediately.
An electrician checks the load, contacts, breaker, panel, and sockets, then repairs loose connections or upgrades the line safely.
