The overloading of a circuit is a major reason leading to frequent short-circuit tripping. A circuit breaker trips if it is attempting to draw more power than it is intended to carry. This happens usually by means of spring-loaded component in the breaker. …

What to do if MCB trips?

Most typically, circuit breakers trip because a circuit is drawing too much current for the amperage rating of the circuit breaker and the wires it feeds. The best way to eliminate this kind of tripping is to reduce the electrical load on the circuit by moving appliances to outlets fed by different circuits.
