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.
Standard Design
An AKD-10 OEM Module stack comes standard with
the following items:
1. Basic stack frame 60, 67 or 74 deep Indoor
Construction Only.
2. Removable top covers including the top front
wire trough with necessary ventilation and dust
covers.
3. Blank instrument panels above each blank

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

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
AKD-10 OEM Module can be labelled accordingly by if the bus is furnished by GE or by the OEM.
Horizontal Main Bus Rating
The main bus rating will be used to size the main bus that is shipped in excess. The horizontal main bus can be
braced for 100 kA maximum duty. The bus is fabricated from copper, and the bus is sized as follows:
A. 1600A bus consists of (1) 0.400 x 4.00 bar per phase
B. 2000A bus consists of (1) 0.500 x 4.00 bar per phase
C. 2500A bus consists of (2) 0.335 x 4.00 bars per phase
D. 3200A bus consists of (2) 0.400 x 4.00 bars per phase
E. 4000A bus consists of (3) 0.500 x 4.00 bars per phase
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
link will be used for 22 wide stacks. In a transformer transition unit the only options are no neutral or
neutral. The neutral bus will be shipped assembled except for the neutral bus in a transition unit, which will
be shipped excess. Be sure the coordination you need matches that of your transformer.

Front Doors and Hinges
Front doors and hinges are optional items. Options include: no front doors,
front doors and hinges, and hinges only. If front doors are specified, the
doors and hinges will be assembled and attached to the stack. If front doors
are not specified a detail drawing of the doors for fabrication is available.
Front doors must be selected if breaker door interlocks are to be provided.
This selection will be applied to all the ordered stacks.
Front Door Latch
Front door latches can be provided only when doors are
selected. There are three types of front door latches:
none, standard, and padlockable. The standard door
latch has a ¼ turn handle. The padlockable door latch
enables the door to be secured with two padlocks, one
- 1/4, and one - 3/8 diameter shank.
Bolted Rear Doors
A full-height vented rear door with hinges or hinges only without doors
are optional. Transformer transition units will be equipped with two
split bolted rear covers when the rear door option is selected. When
the rear doors are not furnished a detailed drawing for fabrication with
a vent detail will be provided. The rear door must be fabricated to GE
specifications because the vents are essential in maintaining the correct
temperature within the stack. If rear doors are selected, then all
stacks will have rear doors and will be shipped mounted to the stack.
Ground Bus Size
There are three options for the ground bus: none,
qty (1) ¼ x 3, qty (2) ¼ x 3. Qty. (1) ¼ x 3
ground bus is rated for 800 Amps and qty. (2) ¼ x
3 ground bus is rated for 1600 Amps. The ground
bus will be fabricated from copper. The required
location of the ground (upper or lower) must be
provided when selecting.
Hoist Rails
Circuit breaker hoist rails are optional and are installed on top of the switchgear. The rails can accommodate a
hoist for easy, safe removal and installation of breakers. The rails enable the hoist to travel the length of the
switchgear, therefore, only one hoist is needed per switchgear line-
up. Rails will be installed at the factory. The hoist and rails increases
the height of the line-up to 103.5 inches. If hoist rails are selected,
then all the stacks with the order will have hoist rails, except
transformer transition sections.

Following items are accessories and shipped as excess material.
Indoor End Covers
The end covers enclose the side of a stack at the end of a line-up. There are three types of end
covers depending upon the depth of the stack: 60, 67, and 74. The end covers are designed
to be used on either end of a line-up. When end covers are ordered they will be assembled to the
first non-transition stack in the order for shipping purposes.
Left Transformer 3-Phase Transition Bus
Specific stack codes must be selected for a transformer transition. Stack code
601-1 or 601-2 is for a Left End Transformer Transition (see Appendix A for more
details). All transformer transition stacks are 22 wide. If a main bus rating is
not selected then bus for a transformer transition stack is unavailable. The
transformer transition bus is based upon the adjacent stack width: 22, 30, 38. The transformer
transition bus will be shipped as excess material.
Right Transformer 3-Phase Transition Bus
Specific stack codes must be selected for a transformer transition. Stack code 602-1 or 602-2 is for a Right End
Transformer Transition (see Appendix A for more details). All transformer transition stacks are 22 wide. If a
main bus rating is not selected then bus for a transformer transition stack is unavailable. The transformer
transition bus is based upon the adjacent stack width: 22, 30, 38. The transformer transition bus will be
shipped as excess material.
Main Bus Splices
Main Bus Splices are required when connecting the Horizontal Main Bus to the ower Connections
on the vertical bus. Working from left to right where the Horizontal Main Bus begins one (1) Bus
Start Spacer is required. When the Horizontal Bus Stops at a ower Connector, one (1) Bus Stop
Spacer is required and if the Horizontal Main Bus is connected to the riser and the connection is
not a stop or a start a Horizontal Main Bus Continuous Spacer is required. These Main Bus

Top Wire Trough End Covers
The top of each stack has mounting areas for terminal blocks. This
mounting area is toward the front of the stack between the front and rear
hoist rails (if provided). Two (2) top wire trough end covers are needed
per line-up to enclose the wire trough on the right and left side of a line-
up. When the top wire trough end covers are ordered they will be
assembled to the first non-transition stack in the order for shipping
purposes.
Brea er Hoist
A circuit breaker hoist is optional. There are different breaker hoists depending upon
stack depth. Hoist rails must be selected on the order sheet. Only one hoist is needed
per switchgear line-up. The hoist and rails increases the height of the line-up from 92
to 103.5. The hoist will be shipped excess. The hoist rails will be mounted to the
stacks.
GE has developed a unique stack configuration identification method called a stack code:
Stac Code
The stack code determines the width of the stack, horizontal bus connection, vertical bus configuration, circuit
breaker location, number of compartments and ampacity of the compartments within the stack. See Appendix
A Stac Codes.
Vertical (Riser) Bus Amps
The vertical bus is available with ratings from 1600A to 4000A in stacks limited to 800 2000A breakers (codes
701 - 751) and ratings of 3200A and 4000A in stacks having 3200 4000A breakers (codes 801- 834). For vertical
bus ampacity ratings for each stack code see page 13 Stack RulesAppendix A Stac Codes. The vertical bus
is fabricated from copper and will be shipped fully assembled in the stack with the necessary bracing hardware
and insulation package (when furnished) in place. A 4000A vertical bus requires a minimum 30 wide stac .
Compartment Depth
The Compartment Depth is the depth of the breaker / auxiliary compartment. Standard depth is 30 and a
depth of 37 must be selected for fused breakers. Stac s must have the same compartment depth to enable
the stac s to be combined into a switchgear line-up.
Stac Depth
There are three different stack depths: 60, 67, 74. The breaker / auxiliary compartment depth plus the bus
compartment depth determines the stack depth. The brea er compartment is 30 deep (standard) and must
be 37 deep with integrally fused brea ers. The bus compartment is 30 deep (standard) and 37 deep when
requested by the customer for more cabling space. Stacks must be the same depth within a switchgear lineup.
Refer to Table 1.0 for complete sizing and dimensional data.

○○○○○○○○○○○○○○○○○○○○○○○
Section Barriers
Optional section barriers are mounted internally on the side of the stack in the bus and cable
compartment. The barrier isolates the bus and cable compartments of adjacent stacks. For all
stack codes except transition sections the section barrier will not be notched. This means notches
will need to be cut into the barrier and sized depending upon the main bus rating and position.
For Transformer Transition Stacks, the section barrier is standard. If a main
bus rating is not selected the size of the notches for the section barriers for
transformer transition stacks will be for 1600- 2000A main bus. For higher
main bus ratings, the notches need to be enlarged. If a main bus is selected,
the notches in the section barriers will match the bus size. The section
barriers are made of flat polyester glass sheet material and will be shipped
attached to the stack.
Rear Wire Trough with Covers
A vertical wire trough with covers, mounted in the rear of the stack is optional.
The wire trough will have mounting for terminal blocks but terminal blocks must be supplied by
purchaser. There are three different options for the troughs in the rear: left, right and both.
Transition stacks can not have a rear wire trough but do contain a mounting pan for terminal
blocks if needed.
Top / Middle / Bottom Power Connectors
Depending upon the stack code selected there may be three (3) positions for power
connectors: top, middle and bottom. The power connectors allow the vertical (riser)
bus to be connected to cables, busway or other horizontal main bus connections. The
power connectors must be specified on the order sheet. To connect two stacks to each
other with the horizontal main bus, both stacks must have power connectors at the
same position, such as bottom bottom.
Stack codes ill determine the unit types required. Additional accessories are also
available:
Auxiliary Compartment Height
An auxiliary compartment is a blank (non-breaker) compartment that can be used for mounting instruments on
the door or inside the compartment
Brea er Type
Stacks are designed for Wave roTM AKD-10 Equipment breakers (CAT #WE). The possible types of Wave rotm
breakers for each compartment position are with the stack codes. Table 2.0 WaveProTM Brea er Interrupting
Ratings on page 16 lists the ratings for the breaker types. More details for the Wave roTM circuit breaker can be
found in Wave roTM Application Guide DET-167.
Key Interloc s
This option provides a means of locking of the circuit breaker in the open, trip-free position when fully connected.
Mounting only for a Kirk Keylock is provided and Kirk keylock is provided by others. Applicable schemes would
be mechanical interlocking of two breakers so only one can be closed at a time, or in load center unit substations,
interlocking of the primary switch and secondary main breaker such that the secondary main must be open
before the primary switch can be operated. Up to two key positions can be accommodated in each breaker
compartment.

Secondary Disconnects Bloc s, Mounting, and Wiring Harness
Secondary disconnects, mounting, wiring and terminal blocks can be installed for two
separate 36 point disconnect blocks. The two (2) positions are specified as either A (left
side) or C (right side). The number of disconnects in the compartment is determined by the
number of disconnects on the circuit breaker. If the circuit breaker designated for the
compartment has any of the following options, then the compartment needs both secondary
disconnects A and C. If the circuit breaker does not have any of these options then only the
A (left side) position requires a secondary disconnect.
A. 7-Stage Auxiliary Switch (6 NO / NC 6 contacts)
B. 2nd Shunt Trip
C. Remote Charge Indicator
D. Open Fuse Lock-out (OFLO) Device - 2000 / 3200 / 4000A breakers
Note: If the breaker is manually operated, has no accessories and is equipped with a ower lus or
MicroVersaTrip lus Trip Unit, then a secondary disconnect may not be required.
Position Switch
The position switch is used to indicate if the breaker is in the Test/Disconnect or Connect
position. The position switch will be supplied without wiring. The position switch
mounting differs depending upon which type of circuit breaker is specified for the
compartment. The switch may be mounted on the bottom or on the rear barrier of the
compartment. The position switch is optional and will be shipped installed.
Below is a table which shows the switching sequence. Make electrical connections as
desired (1/4 wire strip required).
NOTE: USE EDGE GUARD TO ROTECT WIRES FROM ALL SHAR EDGES.
Defeatable Door Interloc
Doors must be purchased if a defeatable door interlock is required. This option prevents opening the
breaker compartment door when the breaker is in the Connected position. The door interlock is
comprised of a linkage, which is mounted on the left side of the breaker compartment, a latch on the
inside of the door and an opening in the door. An opening in the door allows for authorized defeat of
interlock. The door interlock will be shipped installed.
Shutters
Shutters are available as an optional accessory to protect personnel from accidental
contact with the primary disconnects in an energized compartment. The shutters cover the primary
disconnects in the compartment when the circuit breaker is in the withdrawn position.
When the circuit breaker is moved into the connect position the shutters open to
allow connection between the breaker and the primary disconnects. When ordered,
the shutters will be shipped installed. To install current transformers, the shutters
will need to be removed by taking out eight (8) self-tapping screws. Note: The
shutters are NOT available for 1600A frame fused breaker (W F-16) with a 2500A
current limiting fuse.
Open Fuse Loc out (OFLO) Device
The open fuse lockout device is provided with any fused breaker. The OFLO consists of an individual trip
solenoid for each pole, connected directly across the fuse in that phase. When any fuse blows, the
solenoid is energized and trips the breaker to prevent single-phasing. The breaker is mechanically locked
out and cannot be reclosed until the fuse is replaced and the target indicator of the phase involved is
reset. Units for 2000, 3200 & 4000A frame breakers with open fuse lockout (OFLO) devices are furnished
with a unique rejection device that ensures correct breaker installation.

The height of the AKD-10 OEM Module equipment is 92" (97" over the top wiring trough and 103.5" over the optional
breaker hoist). The available breaker stacking space is 84".
Breaker frame size and type determine the width of the breaker sections and also the minimum depth of the switchgear
line-up. When combining stacks into a line-up, the depth of the deepest device in the line-up determines the depth the
line-up. For example, a line-up with a W S-20 breaker, fuse roll-out (depth - 60") and W F-08 breakers (depth - 67")
would be a minimum of 67" deep the W F-08 being the deepest device. Refer to Table 3.0 for section sizing.

Vertical (riser) Bus Ampacit for Stack Codes
Each stack code has an amp range for the vertical (riser) bus rating. The amp ratings of the circuit breakers in a
stack determine the vertical bus rating. See Table 6.0 to determine the rating of the vertical (riser) bus.
Table 6.0

Stack Codes Rules
Different stack codes are located on pages 20-28. These illustrations have been included to show the vertical
(riser) bus and configuration of the compartments. The stack code is given a numeric, for example 701-1. The
700-899 stack codes have 84 inches of total height in which to assemble the combinations of auxiliary and
breaker compartments. The 7 filler compartments for the 800-899 stack codes do NOT have to be specified
because these compartments will be provided when needed.
There are three possible positions (Top, Middle, Bottom) for the main horizontal bus, and the main bus position
is designated by horizontal lines labeled T (top), M (middle) or B (bottom). The vertical lines extending from one
compartment to another designate the vertical (riser) bus. The compartment height, for example 21 or 42, is
shown in the bottom right-hand side of each compartment. The ampere ratings shown beside each breaker
symbol indicates the range of circuit breaker frame sizes that are allowed in the compartment. If the compartment
is not designated for a circuit breaker, the compartment will be an auxiliary compartment.
1. Any breaker compartment shown on the stack drawings can be made blank to provide additional space for
mounting protection, instrumentation, and control devices.
2. Any blank compartment greater than 7 inches high can be used for instrumentation (except vent
compartments).
3. 3200A and 4000A fuse roll-outs are the same size as their respective breakers, therefore any compartment
shown with a 3200A or 4000 A breaker will also accommodate a fuse roll-out and vice versa.
4. Additional cable and conduit space is available by making breaker sections wider (22 inches wide to 30
inches wide, or 30 inches wide to 38 inches wide) or by increasing rear depth by 7 inches for a maximum
depth of 74.
