Blown Ballast

[Jaws]

I was moving my ballast the other day and while doing it, one of the power wire connectors joining the ballast had some metal exposed and touched with the metal ceiling I have above my canopy. As soon as it touched there was a huge flash and a large black burn on the metal ceiling where they made contact. Now the light won't turn back on. Would that be enough to blow the ballast or could it be something else?
