List two distinguishing features between overloading and short circuiting .

Explanation

If the live and neutral wires come in contact directly or indirectly due to defective or damaged wiring in an appliance, the resistance of he circuit becomes almost zero and a huge current flows through the circuit. This is called short circuiting. It may damage the appliance and also cause heating of the line wires, electric spark, fire, etc. Short circuiting can be prevented by using an electric fuse in a live wire.
Overloading occurs when many appliances are switched on at the same time and they draw a large current [exceeding 5 A for lighting circuit and 15 A for heating circuit] from the mains, or due to an accidental hike in the supply voltage. This causes overheating of the wires which may result in fire or damage the appliances. This can be avoided by using an electric fuse in live a wire.
