What Are NFPA 790 and NFPA 791?

  • NFPA 790: Defines the qualifications, competence, and responsibilities of third-party field evaluation bodies (FEBs).
  • NFPA 791: Outlines the procedures and best practices for conducting field evaluations of unlabeled electrical equipment.

Together, they ensure safe, consistent, and code-compliant inspection alternatives for equipment that does not carry a listing or certification mark.

With increasing frequency, Authorities Having Jurisdiction (AHJs) will request accredited field evaluations when equipment fails inspection.

When Do You Need an NFPA 790/791 accredited Evaluation?

  • Failed inspection due to missing UL/NRTL label
  • Installing modified or custom-built equipment
  • Imported equipment not previously evaluated for U.S. use
  • Failed inspection because your legacy equipment was manufactured before NRTL listing was a requirement and now it’s under scrutiny.

Don’t take risks with unaccredited agencies.  Many jurisdictions now only accept field evaluation reports from accredited agencies.
