Ouring normal full power'operation .the 1B diesel generator (0/G) output breaker inadvertently shut during breaker maintenance with the 0/G secured. The breaker's control power had been removed for the maintenance, but the breaker shut unexpectedly as it was being manually racked out. The ensuing electrical transient resulted in a loss of the HBH side electrical system and a reactor trip on the low S/G water level.

The HBH side electrical system was repowered from its startup transformer and plant conditions were stabilized. The 0/G output breaker was replaced and the 0/G retested satisfactorily. The cause of the 0/G breaker closure was binding in the MOC switch rod assembly. The health and safety of the general public was not affected by this event.
