1 Scope

1.1 This document provides general guidance for consistency in nameplates for electrical equipment in accordance with the National Electrical Code (NEC), NFPA 70. This recommended practice addresses nameplate content, formatting of the nameplate information, nameplate location on the equipment, and the durability of the nameplate.

1.2 The guidance provided does not replace the requirements contained in product standards or installation instructions. This document is intended to cover the basic nameplate information needed to safely select and install correctly sized power conductors and overcurrent devices and does not include all required markings for electrical equipment.

1.3 This document was developed due to product standards allowing for flexibility related to how information is displayed on equipment nameplates resulting in nameplate information that can vary significantly between products certified to the same standard. This variability causes difficulties in the field, as every manufacturer provides essential information in a different format based on their interpretation and application of the requirements. As products become more complex, nameplates can become more complex, so if uniformity and consistency are not put into place, issues and confusion in the field may increase.

1.4 Product standard requirements take precedence over any guidance provided in this document.

1.5 This recommended practice does not apply to the factory or field-installed caution, warning, and danger markings.
