NFPA 791 – NEC  2024

NFPA 791 2024 is a specialized electrical-safety reference developed for the consistent field evaluation of unlabeled electrical equipment. It provides recommended practices for determining whether equipment can be evaluated against applicable nationally recognized standards and considered for installation under relevant electrical-code requirements.

The publication is especially valuable when electrical equipment does not carry a recognized listing or labeling mark. It gives field evaluation bodies and other qualified professionals an organized framework for examining equipment, documenting findings, and communicating evaluation results to the authority having jurisdiction.

Key areas addressed include the evaluation of individual pieces of unlabeled equipment, preparation of evaluation records, and procedures for assessing multiple units of the same equipment. The guidance supports a more consistent approach, which can make results easier for inspectors, regulators, equipment owners, and other involved parties to understand and review.

NFPA 791 is designed to be used alongside applicable product-safety standards and the requirements of the authority having jurisdiction. Equipment evaluated through this process should be capable of installation in accordance with NFPA 70, National Electrical Code. The publication also serves as a companion to NFPA 790, which addresses the competency of third-party field evaluation bodies.

This edition is relevant to field evaluation body personnel, electrical inspectors, electrical engineers, code officials, safety managers, equipment owners, manufacturers, contractors, and organizations responsible for assessing modified, custom-built, used, or otherwise unlabeled electrical equipment.

Its concise and specialized coverage makes it a useful addition to technical libraries, inspection departments, compliance offices, industrial facilities, and electrical-safety training programs.
