(How an electric circuit and an electric device can be saved from the damage due to overloading?) |
|
Answer» Ans :- That would be a circuit breaker. A circuit breaker is installed in a utility panel with other breakers, and is set to trip off if a circuit controlled by the breaker draws too much current. This could happen when you plug too many high-amperage devices, such as space heaters, into a single circuit. Without a circuit breaker, such a situation can overheat the wires and cause a fire or a short circuit which could lead to electrocution or death. With a circuit breaker, you will not be able to overload the circuit, as the circuit breaker will trip as soon as it reached a maximum load level. Everyelectric circuitin a wiring system must beprotectedagainstoverloads. Acircuit overloadoccurs when the amount ofcurrentflowing through thecircuitexceeds the rating of the protective devices. ... If thecurrentexceeds 15 amps, thecircuitbreakerwillopen up, cutting off any morecurrentflow. |
