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.

 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 line­up. 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.

 Breaker 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:

Stack 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  Stack 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  Stack 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 stack.

 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. Stacks must have the same compartment depth to enable

the stacks to be combined into a switchgear line-up.

 Stack 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 breaker compartment is 30 deep (standard) and must
be 37 deep with integrally fused breakers. 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.

○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○

11

 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 will 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

 Breaker Type

Stacks are designed for WavePro

TM

AKD-10 Equipment breakers (CAT #WE). The possible types of WavePro

breakers for each compartment position are with the stack codes. Table 2.0 WaveProTM Breaker Interrupting
Ratings on page 16 lists the ratings for the breaker types. More details for the WaveProTM circuit breaker can be
found in WaveProTM Application Guide DET-167.

 Key Interlocks

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 Blocks, 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 PowerPlus or
MicroVersaTrip Plus 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).

 Defeatable Door Interlock

○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○

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 (WPF-16) with a 2500A
current limiting fuse.

 Open Fuse Lockout (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.

Sizing, Weight and Breaker Guidelines

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 WPS-20 breaker, fuse roll-out (depth - 60") and WPF-08 breakers (depth - 67")
would be a minimum of 67" deep  the WPF-08 being the deepest device. Refer to Table 3.0 for section sizing.

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.

Vertical (riser) Bus Ampacity 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
