Never do this.  Since the transformer provides very little inductive limiting
and the spark gap acts as a dead short, you get run away current until you fuses
blow.  Before they blow, you will dim all of the lights in your house.

>2) Will these transformers blow up if they get shorted without any control?

If you have no fuses, it is possible.  A fire could occur.

Use inductive/resistve ballasting and line fuses, not circuit breakers.
