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. 6.4.4, 6.5.4, 6.6.4 (NFPA 99), NFPA 110, NFPA 111, 700.10 (NFPA 70)

Observations: Name: MAIN BUILDING 01 - Component: 01 - Tag: 0918
Based on document review and interview, it was determined the facility failed to maintain periodic testing of the generator, affecting the entire component.
Findings include:
1. Review of documentation on December 12, 2023, between 8:45 AM and 9:30 AM, revealed the facility lacked documentation, verifying a continuous 4-hour exercise of the emergency generator, within the past 36 months.
Interview with the Administrator on December 12, 2023, at 12:30 PM, confirmed the facility could not provide documentation that the 3-year test had been performed.
| | Plan of Correction - To be completed: 12/27/2023
Power Systems Electric, the company that performs the generator inspections for the facility, was contacted about performing a 4-hour exercise of the emergency generator. Power Systems Electric advised us on the appropriate procedure to perform and then document the exercise, which will be completed by 1/31/2023. Upon completion of the 4-hour exercise, we will schedule out a time/date within the coming 36 months to perform the exercise again and maintain compliance.
