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 4 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, readily identifiable, and separate from normal power circuits. 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 - Component: 01 - Tag: 0918
Based on document review and interview, it was determined the facility failed to perform required weekly and monthly maintenance and testing for the emergency generator, which serves the entire component.
Findings include:
1. Review of documentation on December 2, 2025, between 9:30 AM and 10:45 AM, revealed the facility failed to perform the following:
a. 9:50 AM, weekly battery voltage readings;
b. 9:53 AM, monthly maintenance, 30-minute load w/transfer switch.
Interview at the time of the exit conference with the Administrator, Facilities Director and Facilities Supervisor on December 2, 2025, at 1:15 PM, confirmed the facility failed to perform weekly and monthly maintenance and testing on the emergency generator.
| | Plan of Correction - To be completed: 01/31/2026
Upon identification of the deficiency, the emergency generator system was reviewed with the contracted service provider, Winter's Generator. Winter's Generator confirmed the transfer switch is not able to exercise monthly under load. The system has been adjusted to perform a 30-minute load test with transfer switch every Monday at 8:00 AM. Weekly battery voltage readings were completed and documented.
The Facilities Director will re-educate the maintenance team on proper procedures for checking generator battery voltage readings and accurate documentation of readings.
A generator maintenance log and tracking system will be updated to ensure completion and documentation of weekly battery voltage readings and the scheduled 30-minute load test with transfer switch. Generator service reports from Winter's Generator will be maintained on file.
Logs will be audited monthly x3 months and then quarterly x 1 year. Findings will be presented at QAPI for further evaluation and recommendation.
