Estimated Time to Complete Tasks
Wiring the secondary disconnects and verifying they match the switchgear cublicle may take 1 to 8 hrs
depending on the complexity of the original breaker. Once the retrofill breaker is fully prepared, it should
take about 20 minutes to swap out the old breaker and rack in the new EntelliGuard R retrofill circuit breaker
if the proper lifting bar and hoist are available.
he EntelliGuard R retrofill, when ordered with 4 wire ground fault, will be equipped with a Neutral C
adapter. he adapter will modify the GE MicroVersa rip type Neutral C output to a Rogowski sensor output
compatible with the EntelliGuard R’s rip Unit. With this device, it will not be necessary to change the neutral
C in the switchgear to a Rogowski sensor. Note: Neutral C Adapters are designed to modify the signal
from any Neutral C which is compatible with a MicroVersa rip or any newer GE rip Unit type originally
supplied by GE in AKD-8 switchgear from 1979 to 2015. GE type SVG… neutral C ’s are compatible. he old
GE SS Neutral C ’s are not. Neutral sensors working with any Non-GE trip units installed as the result of a
rip unit conversion kit should be assumed to be incompatible with the NC Adapter.

History and Types
AKD
AK—Power Circuit Breaker Equipment
D—Drawout circuit breaker construction
Manufactured from 1951 to 1975, all bolted, copper bus design, all drawout breakers—AK-1, —2, —3,—15 / 25
/ 50 / 75 / 100; with a 4000A-max bus rating. Breakers had a ratcheting drawout mechanism, with an open-
door drawout. Breakers were painted ANSI 61, light gray, manufactured in Philadelphia from 1951 to the
mid-60s and in Burlington, Iowa from the mid-60s to 1975.
he breaker compartment was a welded assembly, and the equipment frame was bolted. Breaker boxes
were stacked to make a vertical section with equipment frame around the breaker boxes. here were no bus
compartment barriers, just an open bus design. Ring silver-plating was applied to bolted connections.
AKD 5—AK 25, AK 50, AKT 50, AK 75, AK 100
Manufactured from 1960 until 1977, the aluminum bus had copper that was “flash-butt welded” to the
aluminum at bolted connections. During that time, AK-2A, 3A -25 / 50 / 50 / 75 / 100 (“A” signifies AKD-5
drawout) were produced. Breakers up to 2000A had primary finger clusters. 3000 & 4000A breakers had a
circular primary finger cluster arrangement in the switchgear compartment. Pull-lanyard drawout
mechanism in the switchgear on early designs was replaced by a single jackscrew mechanism and then
later replaced by a double jack-screw mechanism. Featured is a closed-door, drawout with inner house
breaker compartment, where door moves with the breaker as it is racked in or out. wo bus levels are
available with a ring bus used at 4000A. Particulars include: welded/riveted frame, bus compartment
barriers, line/load separation barriers on mains and ties, isolation barriers on transformer transitions, copper
runbacks on feeder breakers, ring silver-plating on copper, and aluminum bus un-plated (welded
connections). he switchgear is painted sand-gray (beige), with some instrument doors painted blue. AKR-
30/50 in 22"-wide sections were introduced in AKD-5 construction, early 70s. AK25s and AK50s were also
available as substructure kits for OEMs to build around customer gear.
Note: All legacy AK & AKR breakers have a draw out letter code “A”. EntelliGuard R Retrofill breakers for this
gear will have a catalog number beginning with R1 for AK replacements or R2 for AKR-30/50 replacements.
AKD 6—AKR 30/30H, AKR 50/50H/T50H, AKR 75/75H, AKR 100
AKD-6 was manufactured in Salisbury, NC from 1977 to 1981. Some AKD-5s, which were built in Salisbury
from 1975 until 1977, got name-plated as AKD-6. here is no “flash-butt” welded aluminum to copper.
Aluminum bus is tin-plated and bolted at shipping splits (but welded everywhere else). Copper bus design has
ring silver plating at bolted joints. AKR-75 / 100s were introduced during this time. Stab-and-finger
connections on 3200A and 4000A breakers were improvements, versus the round the primary disconnects
on the AKD-5. he 4000A breaker was also narrowed to same width and phase-phase spacing as the 3200A.
he AKD-6 uses inner-house drawout breaker compartments on the 800—2000A breaker compartments.
hey are painted ANSI 61 light gray and breakers have ECS or SS trip units.
AKD-6 should mark a shift away from all AK breakers and to AKR breakers. he AKR-30/50/50H/ 50 breakers
used in AKD6 have a shallow 1” steel front escutcheon are drawout letter code “A” i.e. AKR-4A-30 and will be
replaced by an EntelliGuard R with a catalog number beginning with R2. he AKR-30/50/50H/ 50/75/100
breakers sold to OEMs for their switchgear have a 5” deep plastic front escutcheon & spring loaded sliding
“picture frame”. hese are draw out letter code “B” i.e. AKR-4B-30 which will be replaced by an EntelliGuard R
with a catalog # beginning with R5 up to 2000A frame size and R6 for 3200 & 4000A frame sizes.

10 EntelliGuard R Circuit Breaker Retrofill AKD-8 Installation Manual DEH4154 R05
he AKR-75/100 breakers used in AKD-6 have a shallow 1” steel front escutcheon and vertical primary
fingers. hey are drawout letter code”C” i.e. AKR-4C-75 and will be replaced by EntelliGuard R with catalog
number beginning with R2
AKD 8—AKR 30/30H/30L, AKR 50/50H/T50H, AKR 75/75H, AKR 100, AKR125
AKD-8 was manufactured in Salisbury, NC from 1980 to 1984 and in Burlington, Iowa from 1984 to 1999. It
was mostly replaced by AKD-10 in 1999 to 2000 but was available thru 2015. Model 1 and 2 have extruded
vertical bus. Model 2 was introduced in 1983 to accommodate revised wire harness routing. Model 3 was
introduced in 1991, using a flat bar vertical bus. AKR breakers use MicroVersa rip 9, MV RMS9, EPIC, MV
Plus, MV PM, or EntelliGuard U trip units. Aluminum bus was removed from the design in 1996 in favor of
the standard tin-plated copper bus (silver plated optional).
he AKR-30/50/50H/ 50 breakers used in AKD8 have 5” deep plastic front escutcheon& spring loaded sliding
“picture frame”. hey are drawout letter code “D” i.e. AKR-7D-30. In AKD-8, most 800-2000A breakers are
“feeder” breakers with vertical lower stud & primary disconnect fingers clusters, but 800-2000A breakers
designated as “Main” breakers, have horizontal lower finger clusters, which is the same as “D” letter code
breakers sold to OEM’s. A lower stud rejection bracket differentiates between lower stud orientations.
EntelliGuard R breakers with a catalog number beginning with R3 replace an AKR-30/50/50H/ 50 breaker
with vertical lower stud & fingers. EntelliGuard R breakers with a catalog number beginning with R6 replace
an AKR-30/50/50H/ 50 breaker with horizontal lower stud & fingers.
AKR-75/100/125 circuit breakers used in AKD-8 switchgear have a 5” deep plastic front escutcheon & spring
loaded sliding “picture frame” similar to the small frame breakers. he positions DISC/ ES /CONN are shown
on the side of the front escutcheon by position of the sliding “picture frame”. he GE AKD-8 breakers have a
drawout letter code “D”. OEM versions are drawout letter code “B” and GE Switchboard versions are drawout
letter code “F”. “B” & “F” breakers only differed by appearance items. All Primary disconnect stabs are
vertically oriented. he AKR-125 is a 5000A breaker that had cooling fan. It was release in 1995. None of the
retrofill breakers utilize fans.
EntelliGuard R breakers with a catalog number beginning with R3 replace and AKR-75/100/125 breakers in
AKD-8 switchgear. EntelliGuard R breakers with a catalog number beginning with R6 replace and AKR-
75/100/125 breakers in OEM switchgear or switchboards or GE Switchboard which all utilize an OEM
substructure mounted on a shelf. he R6 breakers will require a different door with a “bump inward” as the
original compartment depth is 1.4” greater than AKD-8.
AKD 10—WPS 08, WPH 08, WPX 08, WPS 16, WPH 16, WPS 20, WPS 32, WPH 32 WPX 32,
WPS 40, WPX 40, WPS 50, WPX 50
AKD-10 was manufactured in Burlington, IA from 1999 thru 2015. he switchgear compartment sizes and
main & vertical bus arrangements are the same as AKD-8 Model 3. he compartments have pull-out rails.
AKD-10 uses WavePro * drawout-only style breakers. All breakers have 4 rollers which align with the
compartment rails. he secondary control wiring for all functions is connected thru either one or two 36
point secondary disconnects with gold plated contacts. Secondary control wiring terminates at fixed
standard locations on the 36 point disconnects. Each breaker has a pump style manual charging handle and
manual push OPEN and Push CLOSE buttons. he front escutcheon is 5” deep with a sliding picture frame,
but is wide enough so the trip unit and new style bell alarm are visible thru the front door of the switchgear.
EntelliGuard R breakers with a catalog number beginning with R7 will replace a WavePro breaker with a
catalog number beginning with WE or W1. EntelliGuard R breaker with a catalog number beginning with R8
will replace a WavePro breaker with a catalog number beginning with WS or W2. Note GE Switchboard
plants initially shipped “WS” style breakers and later shifted to “WE” style breakers to be consistent with GE
Switchgear from Burlington, Iowa. he 5000A breaker had cooling fans. None of the retrofill breakers utilize
fans.
