AKD-10 OEM Module is different than the traditional
switchgear line-up. It is purchased and shipped in
individual vertical sections, which are referred to as
stacks. The stack code determines the number of
compartments and horizontal and vertical bus
configuration. A wide range of options are available
for the compartments, neutral bus, ground bus, and
main bus. The compartments in the stacks can be
ordered as a blank (auxiliary) space, or a circuit
breaker compartment. Circuit breaker compartments
have additional options, such as safety shutters,
secondary disconnects and position switches.
AKD-10 OEM Module component switchgear is
manufactured in GEs ISO 9002 certified facility in
West Burlington, Iowa.

Safety and reliability features
Standard and optional features are available with the AKD-10 OEM Module to
meet the customer demands for maximum uptime system reliability and
personnel safety.
Closed-door operation
Optional breaker compartment doors have no ventilation openings, thus protecting
operators from hot ionized gases vented by the breaker during circuit interruption.
Closed-door drawout
True closed-door drawout construction is standard with AKD10 OEM Module. The
breaker compartment doors remain stationary and closed while the breaker is racked
out from the CONNECT position, through TEST, to the DISCONNECT position. Doors
can be secured with rugged 1/4-turn latches.
Closed-door control circuit accessibility
Standard construction provides a metal instrument panel above each circuit breaker.
This panel can be used by the OEM for mounting a variety of control circuit devices.
Fuses for the breaker close and trip circuits and toggle switches used for testing the
breaker close and trip circuits can be mounted in this panel. The panel is easily
removed for mounting devices and wiring.
Closed-door trip unit setup and display
All Wave roTM breakers have front-mounted trip units. Operators can have full and
safe access to the trip unit information without opening the breaker door. Depending
on the trip unit supplied, the following information is available:
Trip unit type Current sensor rating
Breaker trip rating Trip unit settings **(LT, ST, INST, GF)
Trip targets (optional on ower+) Trip counter (MicroVersaTrip lus/ M)
hase 1-2-3 current readings (MicroVersaTrip lus/ M)

Easy-to-use breaker interlocking and locking
features minimize the risk of operational errors:
Low-voltage power circuit brea er loc ing
As a standard feature, the low-voltage power
circuit breaker can be padlocked in the open
position with up to three 1/4 - 3/8 shank
padlocks to prevent unauthorized closing.
Brea er insertion and withdrawal interloc s
Interlocks prevent racking of the breaker in or out
when the breaker contacts are closed. Breakers
are trip free when not in the CONNECT or TEST
position.
The breaker compartment is designed to
provide operator and system safety options:
Isolated brea er compartment (standard)
Each circuit breaker is located in a completely
enclosed ventilated compartment with grounded
steel barriers to minimize the possibility of fault
communication between compartments.
Safety shutters
Safety shutters are optionally available in breaker
compartments to protect operators from
accidental contact with live conductors when the
breaker is withdrawn.
Defeatable door interloc
This option prevents inadvertent opening of the
compartment door unless the breaker is in the test
or disconnect position. A provision is made for
authorized defeat of the interlock.
Padloc able door latch
This optional feature enables padlocking of the
door latch in order to prevent unauthorized entry
into the breaker compartment.
Brea er rejection feature(standard)
A rejection system is provided as standard in each
breaker compartment to prevent the insertion of
a breaker with inadequate short circuit and/or
incorrect continuous current ratings.

Wheels and guidebar (standard)
All Wave ro circuit breakers are equipped with wheels
and a guidebar to provide easy and accurate drawout op-
eration. When installing the breakers, they are lowered
onto the extended drawout rails. Wheels on the side of
the breaker allow the breaker to be easily rolled into the
cubicle until the breaker engages the racking pins in the
cubicle. The breaker is equipped with a rugged guidebar
that ensures precise alignment of the primary and sec-
ondary disconnects during insertion.
Installation and maintenance are made easy with these
design features:
Accessibility
Accessibility to equipment compartments provides easy
maintenance of the breaker cubicle, as well as convenient
inspection of the bolted bus connections.
Cable space
Conduit entrance area meets NEC requirements. A 7
extended depth frame is available for applications
requiring additional cable space. Section width can also
be increased (from 22" to 30" or 30" to 38") for additional
cable space.
Brea er lifting device
This optional top mounted hoist provides the means for
installing and removing breakers from the equipment.
Control circuit isolation
Control wires can be run between compartments in steel
riser channels. Optional rear wire troughs located in the
rear cable area can provide space for customer terminal
blocks. Intercubicle wiring can be run in a wireway on top
of the switchgear where interconnection terminal blocks
can be located.

GEs manufacturing engineering and testing set the quality standards in the switchgear industry:
Paint finish
Standard paint finish is ANSI-61 light gray. rimer paint process uses the superior E-coat, or
electrodeposition process, based on electroplating principles. Each switchgear part is thoroughly cleaned
and sealed prior to painting. This process guarantees resistance to harsh indoor environmental conditions.
Final paint is the responsibility of the OEM.
Seismic Certification
All OEM Module Equipment has been qualified for use in moderate loading conditions as defined in
IEEE Std. 693-1997. Moderate seismic loading conditions are defined by forces up to 0.25g Z A horizontal
and 0.20g Z A vertical. An accessory kit is available for high seismic conditions.
Complete and accurate documentation
The AKD10 OEM Module information pack contains all the documentation required to design
and assemble the module into a s itchgear lineup.
Other available features and options for AKD-10 OE odule
UL Requirement

Bus Plating
The standard plating is tin for the main, neutral, vertical (riser), and ground bus (when supplied). Fully silver
plated bus is available.
Momentary Bus Bracing ( A RMS Symmetrical)
The vertical bus bars are braced to withstand mechanical forces exerted during a short circuit of 65kA (Standard)
or 100kA (optional) RMS symmetrical. The horizontal bus bars of the main bus when supplied are always
braced for 100kA. Other buswork shall be braced to withstand mechanical forces exerted during a short circuit
equivalent to the maximum interrupting capacity of the associated circuit breakers, or the maximum let-through
current in the case of the load side of a fused circuit breaker.
Insulated / Isolated Bus
Bare copper will be provided as standard for the riser bus and optional
horizontal main bus. The insulated/isolated system fully insulates
the horizontal main bus with fluidized epoxy coating and isolates each
phase of the vertical riser bus with molded polyester glass. If ordered,
the components of the insulated / isolated system will be installed at
the factory with the exception of the optional horizontal main bus and
associated bus insulation hardware which will be shipped excess.
Neutral Bus
There are two (2) positions for the horizontal neutral bus: bottom or top. There are four options for the neutral
bus: none, solid, large frame link, and small frame link. The solid neutral bus comes in one piece. The large
(3200 4000A) and small (800 2000A) frame lin ed neutral buses are separated into three pieces which allow
an in-line neutral current transformer to be easily installed for Main and Tie breaker applications with 4 wire
integral ground fault protection. A large frame link will be used for 30 or 38 wide stacks and a small frame
