if a system is able to procude 5v to 45 v max. 2 ampsto 20 amps max. how do you prevent malfunction of this systsmthrough GFI or circuit breaker? for example. if the max current is20 amps and the system is drawing 20.1 amps. how do we degrade thesystem so that it will go back to 20 amps. draw a circuit of GFI orcircuit breaker to explain please. Please dont shutdown the systemif it goes over the limit, but reverse it back to the right amps orvoltage without ahutting down the system.

The circuit breaker must first detect a fault condition In small mains and low voltagecircuit breakers this is usually done within the device itself Typically the heating or magnetic effects of electric current are employed Circuit breakers for large currents or high voltages are usually arranged with protective relay pilot devices to sense a fault condition and to operate the opening mechanism These typically require a separate power source such as a battery although some highvoltage circuit breakers are selfcontained with current transformers protective relays and an internal control power source Once a fault is detected the circuit breaker contacts must open to interrupt the circuit This is commonly done using mechanically stored energy contained within the breaker such as a spring or compressed air to separate the contacts Circuit breakers may also use the higher current caused by the fault to separate the contacts such as thermal expansion or a magnetic field Small circuit breakers typically have a manual See Answer
