An electrical breaker is dual function an electrical fuse just has one purpose.

∙ 13y agou dont have to replace a breaker every time it blows as u do with a fuse. and if u just dont use a breaker or a fuse nothing will be protected

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.
In a series connection if one component fails the whole circuit fails?
Yes. Open circuit. A: It depends on the failure type a short will not necessarily make an open circuit but rather a non functional circuit.
Compare and contrast a circuit breaker and a fuse?
A circuit breaker is something you can reset. When the switch "trips", the position of the switch goes to the middle. To reset it, move to Off, then On.When a fuse blows, its two external contacts are no longer connected by the internal piece of fuse wire and an electrical current can no longer flow.More technical details about fusesIn all types of disposable fuse, two contacts which are on the body of the fuse are connected to a piece of fuse wire inside. The material used to make the fuse wire, and its thickness, designed to melt - and thus break the circuit - if the current flowing through it exceeds a certain amperage, which is known as the fuse's "maximum rated current".There are many different types of disposable fuse: some are screwed into what looks like a light bulb socket.Other types are small tubes - made of glass or ceramic - with a metal contact at each end. They are held in a fuse holder that has contacts, clips or springs which make contact with each of the fuse's end contacts.Some commonly used automotive fuses are made of plastic and have two flat metal "pins" which plug into a pair of contacts in the fuse box.
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
What is advantage of ac generation rather than dc generation?
!! In india and most of the other countries user ac current. Hence, all the appliances are ac dependable. So generating ac directly would allow up to directly feed the appliances without any converter circuit.
Why sf6 circuit breaker is mostly used in substations rather than other?
Rather than where? Circuit breakers are always located in substations.
Why are two 30amps breaker together?
They are in tandem because they power a 220 VAC circuit, rather then a 110 VAC circuit.

Why won't the switch on my breaker box stay on?
This is properly understood when Ohm's Law is applied: Voltage, Amperege and Resistance are correctly applied to a circuit for it's correct function. The circuit breaker acts as a protective device and trips when a correct electrical circuit does not exist. The wrong breaker may have been installed. the wrong gauge of wire may have been used, the pumps and heaters may be drawing more amps then planned for or a short circuit or loose connection are all possible faults. Contact the electrician that installed the system for resolution of the problem or an outside electrician if the problem isn't corrected. Caution: Water and Electricity should not be trusted when in close proximity.
What would cause a breaker to trip?
A breaker will keep tripping until the fault that caused it to trip is corrected. That's what it is designed to do. There's either a circuit overload or a short circuit. How fast the breaker trips can indicate how overloaded it is. If you are very close to the rating of the breaker you can actually trip it over time. If you are definitely over the breaker will usually trip instantly. If there is a short circuit you can usually tell that by how violently the breaker trips. If you have conduit you can hear the wires banging around in the pipe. A frequently tripping breaker may also be faulty and need to be replaced - breakers are designed to fail by tripping prematurely rather than by not tripping at all, as this is much safer. This is very often the case for breakers that trip at seemingly random intervals, often when very little load is being drawn.
How do you repair printer if the problem is on the cartridge?
If the problem is on the cartridge (as in your rather vague question) change the cartridge. You need to give more details for a specific answer.
What can cause a circuit breaker to suddenly start tripping?
If the breaker trips when nothing is turned on it could be a mouse problem. If it only trips when certain lights or appliances are turned on one of them is probably the reason.If it trips when nothing is being turned on or off something is getting hot. You should then have qualified electrician look at it. Hope this is usefull.
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
Why do the headlights on an 88 wrangler turn off after 20 minutes of driving?
Headlights are typically ran through a resetting circuit breaker rather than fuses for safety reasons. If you have added lights to your Jeep on this circuit, they may be too much of a draw. If not, you may look at replacing the breaker as a likely starting point. 20 minutes sounds like just the right amount of time for it to heat up and trip off.

Aluminium oxide is an example of corrosion of advantage rather than disvantage

Advantage of a transformer over a transformer coupled circuit?
Sounds more like a "homework" or "test" question, rather than a real-world question, and vague, at that! Could you re-phrase your question in a better, more-precise context, or check it for typos? Right now, your question seems to ask "What's the advantage of using a transformer, instead of using a transformer-coupled circuit?"...which makes no sense, since a "transformer-coupled circuit" USES a transformer.
