An overheating wall socket is a serious electrical warning sign. It can be caused by loose contacts, overload, damaged wiring, or using high-power appliances through an unsuitable extension lead.
The socket may heat up when the plug sits loosely, the internal contacts are worn, the terminal screws are weak, or too many appliances are connected to one circuit.
Unplug the devices, stop using the socket if there is a burning smell or dark marks, and switch off the related breaker if needed. Do not open the socket while it is live.
A qualified electrician checks the socket, cable size, circuit load, breaker rating, and panel connections before replacing the socket or upgrading the wiring.
