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.
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.

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

Loss power to air condition in attic even though circuit breaker on. Is there an internal breaker switch that needs to be reset?
There may be a breaker or more likely a pair of fuses. Yes, they may need to be reset or replaced (if fuses).
How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?
For an accurate calculation it will be necessary to know what the size of breaker exists in the pump house and what size conductors are used. Power loss is measured using actual amps required, not size of the circuit involved. But the size of circuit (breaker size) can be used. Voltage must also be known.
Why UPS is required in Distributed Control System?
to maintain control voltage during power loss or spike
Why would a circuit breaker switch spark?
the circuit breaker spark when it comes an over load, loss contact,but the probable cause is loss contact...and also the circuit breaker is going to be damage or destroyed.
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.
What makes a circuit go out without tripping the breaker?
For the entire circuit to go out, the breaker has to trip. The breaker tripping is what causes the loss of power to everything pulling power from that circut. Any single power surge at any point along the circut can cause it. If you have experienced what you are questioning, I suggest you have an electrician take a look at your wiring. You may have serious issues. Breakers a designed to protect the wiring from getting too hot. It's a safety feature for your appliances, your home and those who live in it.
Is it possible to run 2500 feet of underground cable from one 200A breaker box to another 200A breaker box without a power loss?
According to voltage drop calc.you would need to run a 900mcm cable min. for 200 amp 240 volt Every cable has loss because every cable has resistance. It is basic physics.
What causes loss of air blower and cruise control power?
The air blower and the cruise control are completely powered by separate fuses. It is possible that both have blown fuses.
