NEMA Seismic Guideline 1—General Requirements for Seismic Qualification of Electrical Equipment for Commercial Building Codes

Abstract

This guide establishes general guidelines for seismic qualification of acceleration sensitive NEMA electrical equipment rigidly attached to the building structure or foundation.

Equipment not rigidly attached to the building structure or attached with flexible mounts to the building structure is outside the scope of this guide.

Equipment anchorage systems, supports, and attachments are beyond the scope of this document.

Electrical equipment falls under the general category of nonstructural building components as defined in the IBC model code and ASCE/SEI 7 design Standard.

The applicability of this guide for equipment not explicitly referenced in Appendix A has not been considered
