Seismic Restraints for Electrical Equipment
Steven G. Liescheidt, P.E., CSI-CCS, CCPR.
Overview
Earthquakes are more likely to occur in some parts
of the world than others. When buildings are constructed in areas where seismic
activity is likely to occur the building codes and standards require seismic
bracing of electrical equipment. The selection and specification of products for
installation of electrical equipment in seismic zones requires some basic
understanding of how the installation of ducts and pipes needs to be
implemented.
In this course the student will learn the basics
of how to attach electrical equipment to a structure to minimize earthquake damage.
There are many attachment examples shown in the source document for this course
including anchoring and the use of special devices called seismic restraint
devices. This course and the source document do not supersede code
requirements; however, it provides a good fundamental basis for understanding
the practical requirements for installing electrical equipment requiring seismic
bracing. Users of the information in this course and the source document assume
all liability arising from such use.
The student is expected to read and review the material contained in the FEMA 413/December 2004 document – Installing Seismic Restraints
For Electrical Equipment.
The student must take a
multiple-choice quiz consisting of thirty-three (33) questions at the end of
this course to obtain PDH credits.
