This places a lot of added load on the mains supply and is likely to pull the supply voltage down somewhat.
Copper resistances may limit the primary current to less than the breaker current, and this is more dangerous than more current pulling a breaker cleanly.

...if the coil has some turns in short, you said that the voltage of the line will drop: with what percentage 10% or greater?!
