Electrical Systems - Essential Electric System Maintenance and Testing
The generator or other alternate power source and associated equipment is capable of supplying service within 10 seconds. If the 10-second criterion is not met during the monthly test, a process shall be provided to annually confirm this capability for the life safety and critical branches. Maintenance and testing of the generator and transfer switches are performed in accordance with NFPA 110.
Generator sets are inspected weekly, exercised under load 30 minutes 12 times a year in 20-40 day intervals, and exercised once every 36 months for four continuous hours. Scheduled test under load conditions include a complete simulated cold start and automatic or manual transfer of all EES loads, and are conducted by competent personnel. Maintenance and testing of stored energy power sources (Type 3 EES) are in accordance with NFPA 111. Main and feeder circuit breakers are inspected annually, and a program for periodically exercising the components is established according to manufacturer requirements. Written records of maintenance and testing are maintained and readily available. EES electrical panels and circuits are marked and readily identifiable. Minimizing the possibility of damage of the emergency power source is a design consideration for new installations.

Observations:
Name: MAIN BUILDING 01 - Component: 01 - Tag: 0918
Based on observation, document review, and interview, the facility failed to maintain essential electrical system requirements, affecting the entire facility.
Findings include:
Observation and document review on August 6, 2024, between 8:33 a.m. and 8:40 a.m., revealed the following generator deficiencies:
A. (8:33 a.m.) Last documented three-year, four-hour load test was completed on July 30, 2021;
B. (8:40 a.m.) Basement transfer switch had a red alert light illuminated.
Interview with the facility director on August 6, 2024, at 8:40 a.m., confirmed the deficiencies at the time of the survey. The director stated that Palco was scheduled to do testing on August 12, 2024.
| | Plan of Correction - To be completed: 08/13/2024
The 4 hour load bank test is scheduled every 4 years. The test was schedudled in July the soonest we could be scheduled was August 12, 2024. In the future the test will be scheduled every 4 years for an early August appointment giving Palcos enough time to schedule out the test with their staffing.
The critical date was changed in the computer system to read schedule in June every 4 years by the Center Director.
Palcos completed the 4 hour load bank test August 12,2024
