Can a power socket catch fire with nothing plugged in?
The short answer is yes. You see, a fire could start if there are loose or corroded wires, dampness, or if you’ve unplugged something from an overloaded socket. You can also end up with a fire hazard if a short happens in the socket or wiring inside the wall. Whatever the case, if there is a power socket in your property that is hot to the touch, get a professional to check it out ASAP.
