Transformer is HEART of the substation and Circuit Breaker is the LUNGS of the substation.At faulty condition, large amount of current will flow.so trip function is very important at that timeone coil is faulty means, another one coil will trip the connection to the healthy circuit.

Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
Probably not. If the appliance has multiple heating levels then you might get away with it. In this scenario you would only be able to use 30 amps of the appliance's 40 amp capacity before the breaker would trip.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
How do automatic circuit breaker work?
circuit breakers provide two basic forms of protection: overcurrent and short circuit The mechanism used on most simple breakers for overcurrent is a calibrated bimetalic strip > when it draws two much current it gets hot and bends the strip to trip a mechanical arm The mechanism used for short circuit is a electro-magnetic coil > when a fault current goes through the coil, it magnetically attracts a ferrous lever that trips a mechanical release Many larger breakers have electronic trips which monitor the above two functions plus others functions electronically, and a microprocessor then desides to trip the mechanical release
Can an electric range be powered from the same circuit as an electric dyer?
No. The two appliances usually have dedicated circuits. The range will have a two pole 40 amp breaker and be fed with a 3-C #8 copper cable. The dryer will have a 30 amp two pole breaker and be fed with a 3-C # 10 copper cable. As you can see by powering a 40 amp device from a 30 amp breaker, full operation of the range will trip the 30 amp breaker.
You are having to reset your electric water heater breaker daily?
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
What is a shunt-trip breaker?
It works just like a normal circuit breaker with one additional function. A shunt-trip breaker also has a built-in magnetic coil that can be energized externally to trip the breaker. For instance, fire sprinklers are sometimes required in the top of elevator shafts in case of a fire in the shaft. If the sprinklers were to spray water on the electric controls in the elevator cab, people could be hurt or killed, either from electrocution or from the elevator malfunctioning. In these cases, a shunt-trip breaker is installed in the circuit feeding the elevator controls, and the fire alarm system sends a trip signal if it detects waterflow from the sprinkler system. This trips the breaker and removes power from the elevator cab. Once tripped, shunt-trip breakers require a person to manually reset them.
Where do you connect the two leads of a shunt trip breaker?
Usually the breaker's shunt trip coil is tied to a corresponding current transformer that is sized to the amperage that is allowed to be passed through the breaker. These types of breakers can also be connected into a distribution monitoring device. If the monitor detects a phase reversal or phase loss or voltage rise or drop the breakers shunt trip coil is remotely energized and isolates equipment down stream from the fault. Shunt trip coil circuits are also used as safety circuits where the situation calls for only one breaker to be energized at a time. If the second breaker is inadvertently closed, this would allow both breakers to be on, the second breaker's auxiliary contacts that are an internally part of that breaker will close the safety circuit and energize the shunt trip in the first breaker to causing it to open. So as you can see the two wires could be part of many wiring configurations depending on what situation calls for.
Why two shunt trip coil joined in parallel in circuit breaker?
the C.B operation depends upon relay senses. in realy their is trip coil. when ever fault occurs then change in c.t occures[current varies] due to that secondary current in c.t changes then magnetising field of trip coil is varies and then relay contacts open then c.b contacts open..........this is the impotance of TRIP COIL
100amp breaker is 100amp on both phases or one phase?
A two pole breaker protects both L1 and L2 legs. An over current on either leg will trip the breaker.
What are two methods used in most circuit breakers to protect electrical circuits?
There is a heated bimetallic strip that provides a time delay small overload protection. When its contact makes, it energizes a coil to trip the breaker. Some breakers are mechanical, though. There is a coil that trips the breaker instantly on large overload.
What would cause a circuit breaker heating element to trip off?
There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.
How do you trip electrical circuit breaker in normal working condition?
One way is to create a current overload deliberately i.e. run two two high-powered electrical appliances (such as, say, a 12 amp vacuum cleaner and a 2 kilowatt electric kettle) together on a circuit that is protected by a 15 or 20 amp circuit breaker. Or create a short circuit.
Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
Probably not. If the appliance has multiple heating levels then you might get away with it. In this scenario you would only be able to use 30 amps of the appliance's 40 amp capacity before the breaker would trip.
Can you put two fixture on a single pole 15 amp breaker?
Yes, as long as your fixtures don't require more than 1650-watts in an 110-volt supply.ACTUALLY:You should never exceed 80% of the capacity of a breaker. If you actually used the 1650 Watts the breaker would trip because it would have reached the maximum capacity. Make certain that the maximum current draw on any circuit does not exceed that 80% limit.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip.

Will two 110v 20amp breaker give me what I need to make up a 230v 30 amp breaker?
No. The amps must be 30 on each leg and the toggles must be rigged so that if one trips then both trip. It is best to buy the correct 230 V breaker at 30 amps.
