What is Difference between Short Circuit & overloading?

Please answer it with about 4 points.

Overloading: Overloading is the condition when high current, more than the expected/rated value, flow through a circuit. During overload the circuit may burn due to Joule's heating and damage any appliance. For example: if an inverter having 500 watt rating is connected with a heater of 1000 Watt, this will result in an overload. 

Short Circuit: When current in a circuit takes unintended path we call it a short circuit. For example, in a torch circuit if somehow the two terminals of the bulb touch each other the bulb will not glow. Also if somehow the two terminals of the battery touch each other the torch won't work. This condition is called short circuiting. Generally, during short circuit high current flow through the unintended path.

Short Circuit occurs when neutral wire and live wire touch accidentally providing a very low resistance path for current.A large current flows through neutral wire and as we know that H=I2Rt,So Heating effect is very high.This may cause a fire.

Overloading of the circuit occurs when large Number of appliances are connected in a single socket.This causes a large amount of current to flow and the fuse may blow off.This is less dangerous than Short circuits.

Hope it helps you !

to prevent damge to the application by 'short-circuiting,overloading  MCBS(Miniarture circuit breakers) &fuse box are used
