A flow of large amount of current in a circuit, beyond the permissible value of current, is called overloading. It occurs when many electrical appliances of high power rating such as a geyser, a heater , an oven, a motor, etc. are switched on simultaneously . This causes fire.

The circuit is said to have overloaded when more than the desirable load is applied to the circuit. The overload occurs because of the malfunctioning of the equipment or faulty circuits.
