by FAC Maintenance Team, from the Community
Ensure compliance with NFPA 110 Sec 8.4.6 using this ATS testing checklist for power plants. Conduct monthly transfer tests from normal to emergency and back, complete pre-test inspections, and verify control modules, breakers, fuses, and indicator lamps. Record TDNE and TDEN timings, note alarms during synchronization, and confirm restored power. Log hourly readings for ATS E1 and ATS 1 including voltages, current, frequency, load, kW, kVA, kVAR, and power factor. Capture observations, recommendations, photos, and technician signatures to maintain reliable emergency power systems.
