The role of the circuit breaker is what?
to prevent a circuit from overloading if too much current flow safely interrupt the circuit if it becomes overloaded
What are switches used for in a circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
What property would you be testing for if you are using a circuit breaker?
A circuit breaker is not a test instrument, it is a kind of switch that interrupts the supply when that is needed, but it is more than that because circuit breakers are specialised items, and examples exist that can interrupt currents of hundreds or thousands of amps at very high voltage.
Which device designed to open an overloaded circuit and prevent overheating?
Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.A circuit breaker or fuse.

to prevent a circuit from overloading if too much current flow safely interrupt the circuit if it becomes overloaded
What is different Circuit Breker And Isolater?
I think that the questioner is asking what is the difference between an isolator and a circuit breaker.A circuit breaker is a switching device designed to interrupt a fault current.An isolator is not intended to break a live circuit but, rather, to provide a visible separation between a circuit component and live conductors.For example, isolators (or 'disconnectors' in US parlance) are located on either side of a high-voltage circuit breaker. If the circuit breaker requires maintenance, then the procedure is to:a. trip the circuit breaker.b. open the isolators on each side of the circuit breaker, so there is a visible gap between the circuit breaker and the 'hot' conductors.c. apply temporary earths (grounds) between each isolator and the circuit breaker.d. complete a 'permit to work' card.e. begin work.
Is the circuit board wire over which a device issues voltage to signal this request?
an interrupt
Which circuit board wire over which a device issues voltage to signal this request?
interrupt
Will a faulty ground fault circuit interrupt device cause spurious breaker trips?
yes
What are switches used for in a circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
The Function Of A Twenty Amp Breaker?
It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
Can 11kv breaker be installed on 6.6kv line?
Yes. But,circuit breaker are usually rated in terms of current they can interrupt,not the voltage.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
What is the use of interrupt vector?
An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

A circuit breaker is not a test instrument, it is a kind of switch that interrupts the supply when that is needed, but it is more than that because circuit breakers are specialised items, and examples exist that can interrupt currents of hundreds or thousands of amps at very high voltage.
