Best Answer

Overloading the circuit or a device like a power strip will cause the wiring to heat up at it's weakest point and can result in fire, it can also cause insulation to melt resulting in an electrical short.

What causes resistive heating and then a fire?

Resistive heating occurs when electrical current flows through a material with resistance, causing the material to heat up. If the heat generated is not properly dissipated, it can accumulate and lead to a fire if the material's ignition temperature is reached. Overloading electrical circuits, using damaged electrical cords, or faulty connections are common causes of resistive heating and potential fire hazards.
