Frequently Asked Questions
What is an arc flash warning label?
An arc flash warning label is a safety label affixed to electrical equipment displaying the incident energy level, PPE requirements, and approach boundaries. NEC 110.16 requires labelling and NFPA 70E Article 130.5(H) specifies the required information. Labels must be updated when the electrical system changes.
What information must an arc flash label include?
Per NFPA 70E 130.5(H): nominal system voltage, arc flash boundary, available incident energy at working distance and the corresponding working distance, date of the arc flash study, and at least one of: available incident energy with PPE requirements, minimum arc rating of clothing, or site-specific PPE level.
When must arc flash labels be updated?
Arc flash labels must be updated whenever modifications significantly affect the incident energy level — changes to protective device settings, available fault current (utility upgrade), transformer impedance, or equipment configuration. NFPA 70E recommends reviewing labels whenever the arc flash study is updated, typically every 5 years or after system changes.
