Title	Auto Start and Loading of the "B" Emergency Diesel Generator
Event Description	While the plant was in "ER-SC.1", Adverse Weather Plan, due to high winds and offsite power in a 50/50 alternate lineup, a momentary loss of offsite power circuit "751" occurred. This resulted in an undervoltage condition on safeguard busses "16" and "17". The "B" emergency diesel Generator automatically started and energized buses "16" and "17" . Entry was made into AP.Elec.1, Loss of 12A and/or 12B busses. The offsite electrical lineup was changed to 100/0 on circuit "767". Safeguard busses were re-energized from offsite power and the "B" diesel generator was secured and returned to automatic. This sequence of events took 22 minutes.
