On a star delta starter a motor overload or a motor going to ground and cause a short circuit will cause the overload protection to trip. These overloads have to be reset before the motor can be restarted.

What can a loosely connected electrical wire in a breaker panel cause?
A short, which will trip the main breaker.
In a star-delta starter what could be the problem if the motor does not rotate in star but rotates in delta?
One of the three phase contacts in the star contactor could be burned open or just open not allowing the motor to start because of a single phase condition. The time interval between star and delta connections could be small enough that the motor heaters will not catch the single phase condition and trip. When the motor goes into delta (which is now across the line starting) all of the three phase contacts in the contactor close and the motor starts.
Is Okavango Delta a good place to bring your students for a field trip?
The Okavango Delta would be a great diverse area to take students on a field trip provided that the school has funds for a field trip that can reach to Africa.
Can earth fault current go up passing through the downstream panel and directly cause a trip at the upstream panel which have higher set point of earth fault protection?
If the fault is a direct short to ground, the fault current can be high enough to trip the upstream protection.
Why is the automatic star to delta starter tripping?
The only thing that will trip the starter, is the load of the motor. Check the motor leads to make sure you have not crossed them over coming from the motor junction box. If the motor current is normal nameplate full load amps when run across the line then reduce the timing of the timer on the switch over from star to delta.
Will a GFI outlet keep tripping because it's line is wired to a fuse box panel where the neutral and ground are together?
No, that alone would not cause a GFCI to trip because that is the proper way to wire a panel.
What will cause a star-delta starter to trip a generator when started in star?
One or more reasons may be:The load of the motor (HP) is too large for the output of the generator.The generator's breaker is sized too small for the generator's full load output.Short circuit in the motor.Megger the motor first to see that the windings have not grounded-out. Windings to ground should be above 5 meg.

How do you wire star delta motor having no labels of wires?
You can't , without knowing which winding is which . 9 times out of 10 it will just trip your protection device if it's connected wrong . U need to watch for it starting i'n forward i'n star but when it kicks into delta goes i'n reverse . If u take the motor to a winding shop they should be able to identifie which winding is which .
