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 dc shunt generator can not induce any voltage with rated speed?

Two things could have occurred. (1) wrong direction of rotation causing loss of residual magnetism or (2) loss of residual magnetism over long period of no use. can be remedied by "flashing" the shunt field winding howlumf


What is phase loss?

Phase loss is the loss of power to a specific area of the circuit. Phase loss can result from exposed wires or damaged wires or even downed power lines.


What is the difference between voltage drop and power loss?

voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming


Why loss of field-protection is important?

loss of field protection is important because when a synchronous generator looses field excitation its acts as an induction generator and draws reactive power from the system which heats and damages rotor so as soon as the loss of field excitation is sensed the generator breaker should be opened as the rotor and the stator would both heat up and could damage.

One of the 120 volt legs in the main breaker has lost power?

If one of the 120-volt legs in the main breaker has lost power, it can cause issues with appliances and devices operating on that circuit. This can lead to uneven power distribution in your electrical system and may require troubleshooting by a qualified electrician to identify and resolve the underlying cause of the power loss.


Why are the outlets not working after a power outage?

After a power outage, outlets may not work due to a tripped circuit breaker or a blown fuse. This can happen when the sudden loss of power causes a surge when it comes back on. Resetting the circuit breaker or replacing the fuse can often fix the issue.


Why UPS is required in Distributed Control System?

to maintain control voltage during power loss or spike


Why is there no power at home?

There may be no power at home due to a power outage, a blown fuse, a tripped circuit breaker, or a problem with the electrical wiring. It is important to check these potential issues to determine the cause of the power loss.


Why is there no power in the house?

There may be no power in the house due to a power outage, a blown fuse, a tripped circuit breaker, or a problem with the electrical wiring. It is important to check these potential issues to determine the cause of the power loss.


Why is there no power to the house?

There may be no power to the house due to a power outage, a tripped circuit breaker, a blown fuse, or a problem with the electrical wiring. It is important to check these potential issues to determine the cause of the power loss.

Why is there no power to the garage door opener?

There may be no power to the garage door opener due to a tripped circuit breaker, a blown fuse, a disconnected power source, or a malfunctioning garage door opener. It is important to check these potential issues to determine the cause of the power loss.


Why did your 1990 ford ranger lose power while driving?

i replace the erg,tps,idle control module and ignition control module,and while driving past 30mph i loss power why


To run a 220 volt cable about 21 ft from breaker to garage will there be any loss of power?

Not enough to make any difference to any type of equipment that you want to run.


Why DC source is required for a breaker?

A high-voltage circuit breaker's trip coil is normally operated from a d.c. supply -provided by a bank of batteries located in the substation. This ensures that, in the event of a total loss of a.c. power to the substation, the protection system remains effective.
