• Seismic Certification
AKD-10 switchgear with WavePro circuit breakers has been shake-table tested
in accordance with ICC-ES-AC156 to the requirements of IBC-2003. IBC is the
International Building Code, first released in 2000 by the International Code
Council (ICC). IBC incorporates and replaces the NBC, SBC and UBC.
AKD-10 has been tested to the following ratings:
S = 1.4g, S = 206%, I = 1.5, for z/h > 0
ds s p
S = 2.0g, S = 300%, I = 1.5, for z/h = 0, where
ds s p
S is the maximum considered earthquake response in a certain region
s
S is a measure of ground acceleration for given site and location conditions,
ds
and is dependent on Ss (this is similar to specifying a UBC seismic zone)
I is the importance factor, measuring the criticality of the equipment to life
p
safety. Equipment with an I
event, whereas equipment with an I
z/h specifies the location of the switchgear, z, in relation to the height of the
structure, h. z/h = 0 indicates the switchgear is installed at ground level. z/h
> 0 indicates the switchgear may be installed anywhere in the building.
AKD-10 has been certified for use in all IBC-2003 Seismic Use Groups, Occupancy
Importance Factors and Seismic Design Categories. In addition, AKD-10 has been
qualified to IEEE-693-1997 for Moderate and High Seismic loading conditions.
• Complete and accurate documentation
The AKD-10 design makes extensive use of computer-aided engineering and
design. All customer documentation is generated via linked engineering and pro-
duction systems for seamless ordering of materials and manufacturing of parts.
This integration and linking of systems assures consistently accurate customer
and manufacturing documentation and optimized equipment designs, all driven
by the engineer's system inputs. Customer documentation includes a set of
mechanical and electrical drawings plus a bill of materials for the switchgear.
The mechanical drawings show the switchgear elevation with one-line diagram
and floorplan, circuit breaker schedule with trip ratings and cable data, and lay-
outs for all doors and panels that are used for device mounting. The electrical
drawings include three-line diagrams showing metering and relaying circuits,
schematics for breaker control and auxiliary circuits, and wiring diagrams showing
the switchgear internal wiring. The bill of materials provides catalog and rating
information for the protection, instrumentation and control devices as well as
details on the WavePro circuit breakers. Electronic files of the mechanical and
electrical drawings are available for customers who are integrating the
switchgear drawings into their plant electronic documentation.
