Arc-flash hazard warning

Blog Post created by gmoniz Employee on Jun 19, 2015

The arc-flash hazard warning requirements in 110.16 may be expanded in the 2017 NEC. Code Making Panel 1 has developed a first revision based
on the requirements in the 2015 edition of NFPA 70E that would require additional labeling on service equipment. These installation-related requirements will be located in a new first level subsection 110.16(B) and require service equipment to contain the following information:

    Nominal system voltage

    Arc flash boundary

    At least one of the following:

        Available incident energy and the corresponding working distance

        Minimum arc rating of clothing

        Site-specific level of PPE
