1991 1 of 1 MAJOR SAFETY-RELATED MAINTENANCE Ma 1991 1-M-1 The auxiliary building supply ventilation unit 1-HV-AES-2 motor breaker tripped open and its motor wiring termination was excessively hot during operation.
The problem was determined to be a loose wiring connection which caused excessive
- heat, damaging both the motor and its power feed cable.
The motor and power cable were replaced and the fan was restored to operability.
