What causes wire to overheat?
The electrical current through the wires itself causes the home wiring to heat up. This is because as the electrons flow they come across the resistive forces of the medium’s material, releasing energy that is expended in the form of heat energy.
How hot is an electrical fire?
The heat generated can be as high as 4,000 degrees Celsius – hot enough to vaporize metal and ignite a victim’s clothing. A form of explosion dissipates excess energy from the arc.
Can an outlet catch fire with nothing plugged in?
Answer: An outlet always has power to it as long as the breaker is turned on, so yes it can start a fire when there is nothing plugged into it. A light fixture that is turned off, on the other hand, would be very unlikely to cause a fire.

Loose and disconnected wires can become hot enough to start fires or can create serious shock hazards because the breaker doesn’t always trip and shut off the power.
Why does a loose electrical connection cause heat?
When a connection becomes either loose or corroded, it develops resistance. This resistance dissipates power in the form of heat when current flows through it. Even a resistance as low as 5 ohms can produce more than enough heat to burn up the connection and surrounding wires.
