Need Help! Okuma MC4VA Tripping Main Breaker at End of Program

Leave it to me to have the weirdest issues of anyone. My mill is tripping the main breaker every time at the end of the program. The machine goes to home position and everything is happy, but then, the breaker trips every time. Right as the amber "done light" is about to kick on the machine completely shuts off. It does it with an M30 or M2 command. It also does it with programs that do not go to travel limits at the end. It stops the spindle to do tool changes fine mid program. I am not thinking it has anything to do with servo/spindle drives or motors.

Any ideas?!

Thanks in advance.
