Benefiting from the New Field Evaluation Standard NFPA 791


Field evaluations on unlabeled electrical equipment are conducted every day. Until now, a standard for the field evaluation process has not existed in the US. New or used electrical equipment not certified, listed, recognized, or classified as a complete unit or assembly is considered to be unevaluated by Authorities Having Jurisdiction (AHJs). These unlabeled pieces of equipment are required to undergo a "field evaluation" to ensure electrical safety. It is estimated that there are more than 40,000 different jurisdictions in the US, all differing in their requirements as related to machinery listing and labeling. This can get confusing and costly if you are not educated on the proper requirements and procedures. With the new NFPA-791: Recommended Practice and Procedures for Unlabeled Electrical Equipment Evaluation, AHJ's, inspection bodies and industry are provided with industry approved recommended practices and procedures for evaluating unlabeled electrical equipment, determining the acceptability of evaluation results reported by recognized third-party evaluation bodies, and evaluating multiple units of the same equipment.
