Know the latest Standards for Emergency & Standby Power Systems
Give facilities reliable auxiliary power on demand with the updated 2013 NFPA 110.
If disruption of the normal utility supply occurs, readiness of emergency power is a key consideration in safeguarding building occupants. The NFPA 110: Standard for Emergency and Standby Power Systems covers performance requirements for power systems to give an alternate source of electrical power in the event that the primary power source crashes. Power systems covered include controls, power sources, transfer equipment, supervisory equipment, and all related electrical and mechanical auxiliary and accessory equipment needed in order to supply electrical power to the load terminals of the transfer equipment. 24 pp.
Among the changes in the 2013 edition of NFPA 110 are:
- Clarification that the Standard is intended to apply to Level 1 or Level 2 emergency power supply systems (EPSSs)
- Operation testing and routine maintenance provisions cover existing and new EPSSs.
- Revised definitions of non-automatic transfer switch and automatic transfer switch for consistency with NFPA 111 and correlation with relevant product standards
- Revised material on Level 1 and Level 2 EPSSs clarifies the function and applicability of each type of system
- Differentiation of requirements for acceptance testing for unoccupied and new buildings versus those for existing occupied buildings and facilities. In addition, criteria for step-testing intervals, test duration, and required documentation have been modified.
- Revised rules for operational test durations for spark-ignited prime movers and diesel. Also, the 36-month test requirement has been revised to clarify the maximum duration, the minimum acceptable EPS loading or operating condition, and the method of test initiation.
