Understanding an NFPA110


The NFPA Standards Council recently released the 2013 edition of NFPA 110. NFPA 110 covers construction, installation, maintenance and operational testing requirements for Emergency Power Supply Systems (EPSS).

This year’s edition featured certain edits and changes. Chief among the changes in this edition were several adjustments, including informational Annex recommendations, intended to improve Emergency Power Supply System (EPSS) reliability through better fuel oil management processes.

The following are some highlights of this year’s NFPA 110:


Level 1 – System shall be installed when failure of the equipment to perform could result in loss of human life or serious injuries.

Level 2 – Systems shall be installed when failure of the EPSS to perform is less critical to human life and safety and where the AHJ shall permit a higher degree of flexibility that provided by a Level I system.

Control Function

1) Automatic remote-start capability.
