ATS transfer testing verifies that the ATS can reliably switch power from the primary source (e.g., utility) to the emergency source (e.g., generator) and back, minimizing downtime and ensuring continuous power supply.
Identifying potential issues
Testing helps detect any malfunctions or problems with the ATS mechanism, control system, or connections before they cause a critical failure during a real power outage.
Meeting regulatory requirements
Testing is mandated to ensure compliance with safety standards and regulations in accordance with NFPA.
