ACG Members Jesse Felter, SSRCx and Mark Gelfo, CxA, TLC Engineering Solutions discuss how commissioning emergency power supply systems requires thorough knowledge of codes and several building systems in Consulting-Specifying Engineer magazine.
The commissioning of complex emergency power systems requires the commissioning provider (CxP) to possess technical knowledge of applicable regulations, standards and codes in addition to considerable real-world experience with emergency power systems and integrated systems testing.
When discussing emergency power systems, it is important to understand a few key distinctions in equipment and system terms. NFPA 110: Standard for Emergency and Standby Power Systems defines emergency power supply systems (EPSS) as including the emergency power source (generator), distribution (such as paralleling switchgear) and transfer switches. Whereas the emergency power supply (EPS) includes only the emergency power source (generator) and any distribution upstream of the transfer switches.
