What is overloading in electric current?

Answer 1

An 'overcurrent' can be an 'overload current' or a 'short-circuit current'. An overload current exists when the load connected to a circuit draws more current than the circuit is designed to carry continuously. A short-circuit current is a high current resulting from a fault between a line conductor and the neutral conductor or earth.

Answer 2

Overloading of electric circuit means that the current circulating in the circuit becomes more than the capacity of components in the circuit to withstand the current. All components in the circuits have some resistance passage of electricity through this resistance produces heat which is directly proportional to the square of current flowing. The components are designed to withstand only that much of heat as is generated by maximum designed current. When the current is more than this level, or in other words when the circuit is overloaded the components get overheated, leading to their damage.

Frequently electric circuits in homes, factories, and other electrical installations incorporate fuses, which are essentially circuit component which protect other components in the circuit by quickly melting or burning out when the circuit is overloaded, resulting in breaking of the circuit. In common language this is called blowing of fuse.

Answer 3

Overcurrent protection is used to isolate faults (it shouldn't operate due to load). Overload protection is used to remove load when it is beyond the maximum rating of the transformer.

Answer 4

In an electrical system over load means over current.

Answer 5

An overload in an electrical system indicates that the system is using a larger amount of electrical current than it was designed to use.
