Considerations for
seismic qualied installations
Switchboards that are “seismic qualified” require additional
considerations. Because electrical equipment is installed as
part of a system, pre-engineering layouts are critical in seismic
applications.
When Eaton switchboards are marked as “seismic qualified,”
anchoring the switchboard is critical. Experienced engineers in
seismic requirements should select methods and techniques of
attachment and tested anchoring systems. Embedded concrete
anchors or steel attachments must be adequate to resist the forces
established by the local building code. Bolts of the proper grade of
steel must be correctly sized and torqued. The embedded anchors
must be correctly installed in accordance with the method specified
by the anchor manufacturer. Refer to seismic instructions provided
by Eaton for more information.
Conduit layout in concrete for loads entering and/or exiting the
bottom must be designed and installed to prevent damage from
an earthquake. If top entry is necessary, seismic fittings or flexible
conduit is needed.
Consult applicable local building codes and regulatory agencies for
other specific requirements for seismic installations.
Additionally, six (6) inches of space should be added to the length of
the switchboard assembly to accommodate seismic anchor plates.
Contact Eaton for additional information.
Installation
Use caution and appropriate equipment and practices when moving
switchboard into its final position.
CAUTION
SWITCHBOARD IS TOP-HEAVY. USE CARE IN HANDLING.
Determine the switchboard orientation with the use of manu-
facturer’s drawings and markings on the switchboard sections.
Switchboards may be shipped either in individual sections or in two
or more sections joined by the manufacturer. (See Figure 7 and
Figure 8.)
Figure 7. Switchboard A—Front View
ote:N Switchboard A has a shipping split between Sections 1 and 2. This is
depicted by “*” within the circle between sections.
Figure 8. Switchboard B—Front View
ote:N Switchboard B, without an asterisk, ships with sections bolted together.
The drawing supplied with the switchboard will indicate the correct
orientation of sections by section number. Each section will have a
label with the UL listing mark designating “Deadfront Distribution
Switchboard Section ___ of ___.” The manufacturer will fill in the
blanks prior to shipment. An example: The first section of a three-
section switchboard will read “Section 1 of 3.” Section 2 of 3
would be mounted adjacent per the manufacturer’s drawings.
(See Figure 9.)
