Guide to NSF Electrical Certification Marks
The NSF certification mark is your assurance that the product has been tested and certified by one of the most respected Nationally Recognized Test Laboratories (NRTLs) in existence today. The mark is recognized and valued by consumers, manufacturers, retailers and regulatory agencies worldwide.
Reference the below guidelines for NSF’s electrical and fire safety certification marks.

NSF Electrical Field Evaluation Labels
Product certification or component recognition is not always an option, like in the cases of custom installations or one-off designs. In those instances, a field evaluation may be a suitable alternative to show compliance to the Authority Having Jurisdiction (AHJ). In addition to the NSF Field Evaluation Label, a report detailing the evaluation and inspection of the product is provided. NSF Electrical Field Evaluation Labels are only applied by an NSF representative directly onto the investigated product.
Note: These labels are not certification marks.
