Ballast

I changed out a bad ballast in a 48" fixture with a brand new one. 3 days later it too is dead. What could be the prob? Think it was a dud ballast? The service is 3 phase and the voltage on the origianl ballast was 120V.

Lots of possibilities.
Mis-wired. Fluctuating voltages. Poor ground connection. Bad ballast out of the box.
