GENERAL
The Cooper Power Systems Loadbreak
Elbow Connector is a fully-shielded
and insulated plug-in termination for
connecting underground cable to
transformers, switching cabinets and
junctions equipped with loadbreak
bushings. The elbow connector and
bushing insert comprise the essential
components of all loadbreak
connections.
Cooper Loadbreak Elbows are molded
using high quality peroxide-cured
insulating and semi-conducting EPDM
rubber. Standard features include a
coppertop connector, tin-plated copper
loadbreak probe with an ablative
arc-follower tip and stainless steel
reinforced pulling-eye. An optional
capacitive test point, made of corrosion
resistant plastic, is available for use
with fault indicators (see Catalog
Section 320-10).
Cable ranges are sized to accept a
wide range of cable conductor and
insulation sizes. This range taking
allows the same elbow to be used on
either 175 mil or 220 mil cable within
a given conductor size.
The coppertop compression connector
is a standard item to transition from the
cable to the loadbreak probe. An
aluminum crimp barrel is inertia-welded
to a copper lug. The aluminum barrel
makes the connector easy to crimp
and the copper lug ensures a reliable,
tight, cool operating connection with
the loadbreak probe.
INSTALLATION
Cable stripping and scoring tools,
available from various tool manufacturers, are recommended for use
when installing loadbreak elbows. After
preparing the cable, the elbow housing
is pushed onto the cable. The loadbreak
probe is threaded into the coppertop
connector using the supplied installation
tool or an approved equivalent. Use a
shotgun stick to perform loadmake and
loadbreak operations. Refer to
Installation Sheet S500-10-1
(5000050751) for details.

Loadbreak Bushing Insert
500-12
GENERAL
The Cooper Power Systems RTE®
Bushing Insert threads into a universal
bushing well to provide the same
function as an integral loadbreak
bushing. Using bushing inserts makes
field installation and replacement
possible and efficient. Bushing
inserts and elbow connectors
comprise the essential components
of all loadbreak connections.
The RTE Bushing Insert uses a
patented “ALL COPPER CURRENT
PATH,” containing only one current
transfer point, within the insert itself.
The uncomplicated nature of the current path design delivers superior,
reliable performance.
An internal hex broach allows for
positive torque controlled installation.
Using the optional installation torque
tool the bushing insert can be properly tightened into the bushing well without the fear of accidentally breaking
the bushing well stud.
Cooper's exclusive latch indicator
ring, located on the circumference of
the bushing's collar, eliminates the
guesswork of loadbreak elbow installation on the bushing insert. The
bright yellow ring provides immediate
feedback to determine if the elbow is
properly installed on the insert. If the
yellow ring is completely covered by
the loadbreak elbow, it is fully
"latched," if the ring is visible, the
elbow can be installed correctly
before any problems can occur.
The bushing insert meets all the
requirements of ANSI/IEEE Standard
386 and is completely interchangeable
with mating products that also meet
ANSI/IEEE Standard 386. When
mated with a comparably rated
component, the bushing insert provides
a fully shielded and submersible
connection for loadbreak operation.
INSTALLATION
No special tools are necessary.
The insert can be installed by hand
or with the assistance of a torque tool.
Using the hex-broached base (see
Figure 2) and the optional Installation
Torque Tool, consistent installation
can be easily achieved. Refer to
Installation Instruction Sheet S500-12-1
for details.

Loadbreak Rotatable Feedthru Insert
500-13
GENERAL
The Cooper Power Systems 15 kV
Rotatable Feedthru Insert is used to
provide dual bushings from a single
apparatus bushing well. It makes
converting radial-feed transformers to
feedthru transformers and adding
in-line arrester protection both easy and
practical. Its patented, built-in torquelimiting ratchet prevents operators from
accidentally breaking bushing well
studs during installation. The ratchet
feature also allows the operator to
rotate the feedthru insert 360° to orient
it in the best position for the application.
The bail assembly supplied with the
kit can be used to lock the feedthru
in position.
The Cooper Rotatable Feedthru Insert
incorporates an all copper current path
and peroxide-cured EPDM insulation
and semiconducting shield. It fully
meets the requirements of IEEE
Standard 386™. When mated with
comparably rated products, the insert
provides a fully shielded and
submersible loadbreak apparatus
connection.
Cooper’s latch indicator ring, located
on the circumference of the bushing’s
collar, eliminates the guesswork of
loadbreak elbow installation on the
bushing interface. The bright yellow
ring provides immediate feedback to
determine if the elbow is properly
installed on the bushing. If the yellow
ring is completely covered by the
loadbreak elbow, it is fully “latched,”
if the ring is visible, the elbow can be
installed correctly before any problems
can occur.
INSTALLATION
Instruction sheet S500-13-1 details the
safe installation procedures that should
be followed and are included with each
insert. No special tools are required for
the proper installation of the insert. A
cleaned and lubricated insert is simply
placed in a bushing well and turned in
a clockwise direction. When the
torque-limiting ratchet releases, giving
an audible clicking, the insert will be
properly installed and tightened to the
correct torque. Continued rotation in a

GENERAL
The Cooper Power Systems 200 A,
15 kV Class Loadbreak Portable
Feedthru provides two internally bused
8.3/14.4 kV loadbreak interfaces meeting all requirements of IEEE Standard
386™ – Separable Insulated Connector
Systems. It is used in pad-mounted
equipment, underground vaults, and
other apparatus to bypass transformers, to test and ground circuits, and to
provide open point deadfront lightning
arrester protection when used with the
Cooper Power Systems M.O.V.E.™
Arrester. Sectionalizing of cable runs,
to find and isolate cable faults, is
made easy when the portable feedthru
is used with 15 kV Class (8.3/14.4 kV)
loadbreak elbows and other accessories
meeting the requirements of IEEE
Standard 386™. When mated with
comparably rated products, the
portable feedthru provides a fully

Loadbreak Junction
GENERAL
The Cooper Power Systems 200 A,
15 kV Class Loadbreak Junction
provides two, three or four 8.3/14.4 kV
loadbreak interfaces that are internally
bused together and meet all requirements of IEEE Standard 386™ —
Separable Insulated Connector
Systems. Loadbreak junctions are used
in pad-mounted apparatus, underground vaults, and other apparatus to
sectionalize, establish loops, taps, or
splices, and to facilitate apparatus
changeouts. Sectionalizing a cable
run to find and isolate a cable fault is
made easy when a loadbreak junction
is used with 15 kV Class loadbreak
elbows and other accessories meeting
the requirements of IEEE Standard
386™. When mated with a comparably
rated product, the junction provides a
fully shielded, submersible, separable
connection for loadbreak operation.
The junction has a continuous solid
current path of all copper alloy. No
aluminum components are used. It
also has an ablative arc interrupter
with superior de-ionizing properties.
The body is molded of high quality
peroxide-cured EPDM insulation and
has a molded on peroxide-cured semiconductive EPDM shield.
Cooper’s latch indicator ring, located
on the circumference of the interface
collar, eliminates the guesswork of
loadbreak elbow installation on the
interface. The bright yellow ring provides
immediate feedback to determine if the
elbow is properly installed on the
junction. If the yellow ring is completely
covered by the loadbreak elbow, the
elbow is fully “latched.” If the ring is
visible, the elbow is not fully installed,
so the operator can correct it before
any problems occur.
The loadbreak junction has an
adjustable stainless steel bracket for
mounting at various operating angles
on flat or curved surfaces, with up to
90° tilt in 10° increments. The solid
backplated channel provides strong,
rigid support of the junction for optimum
loadbreak operation. Parking stands
accommodate insulated standoff
bushings or portable feedthrus. Drain
wire clamps can each accommodate
two wires up to 1/0 stranded (3/8"
diameter).

500-22
GENERAL
The Cooper Power Systems RTE®
200 A, 15 kV Insulated Standoff
Bushing meets the full requirements of
IEEE Standard 386 Separable
Insulated Connector Systems, and
provides a single loadbreak interface
made of high quality peroxide cured
EPDM rubber. It is used to isolate and
sectionalize energized cable in
padmounted cabinets, underground
vaults, and other apparatus. Temporary
or permanent parking of energized
200 A, 8.3/14.4 kV loadbreak elbow
connectors that conform to IEEE
Standard 386 is simplified with use of
the insulated standoff bushing.
The insulated standoff bushing is
designed to be installed in the parking
stand mounted on a transformer or
other apparatus. A grounding lug is
provided on the standoff bushing
bracket for attachment of a drain wire
to ensure deadfront construction. When
mated with a comparably rated product,
the insulated standoff bushing provides
a fully-shielded, submersible, separable connector for energized operation.
The standard insulated standoff bushing has a stainless steel eyebolt with
a brass pressure foot. The molded
EPDM rubber body is bolted to a
stainless steel base bracket using a
galvanized steel holddown ring. A
completely stainless steel bracket
assembly is available for extremely
corrosive environments.
Cooper’s exclusive latch indicator
ring, located on the circumference of
the bushing’s collar, eliminates the
guesswork of loadbreak elbow installation on the standoff bushing. The
bright yellow ring provides immediate
feedback to determine if the elbow is
properly installed on the bushing. If
the yellow ring is completely covered
by the loadbreak elbow, it is fully
“latched,” if the ring is visible, the
elbow can be installed correctly
before any problems can occur.
INSTALLATION
No special tools are required. A
hotstick tool is used to place the
standoff bushing in the parking stand
on the front plate of the apparatus.
Refer to Installation Instruction Sheet
S500-22-1 for details.

Loadbreak Bushing Insert
500-26
GENERAL
The Cooper Power Systems 25 kV
Bushing Insert threads into a universal
bushing well and uses a patented
design with an all copper current
path. The uncomplicated nature of
the current path design delivers
superior, reliable performance.
Latch Indicator Ring
The latch indicator ring, located on
the circumference of the bushing's
collar, eliminates the guesswork of
loadbreak elbow installation on the
bushing insert. The bright yellow ring
provides immediate feedback to
determine if the elbow is properly
installed on the insert. If the yellow ring
is completely covered by the loadbreak
elbow, it is fully latched. If the ring is
visible, the elbow can be installed
correctly before any problems can
occur.
Internal Hex Broach
The internal hex broach allows for
positive torque controlled installation.
Using the optional installation torque
tool, the bushing insert can be properly
tightened into the bushing well without
the fear of accidentally breaking the
bushing well stud.
Long Insert
If additional clearance between the
transformer faceplate and the high
voltage underground cables is required,
the long insert version is recommended.
Its longer design provides an additional
three inches of clearance, which may
be important if there is a problem with
cable congestion due to the placement
of the primary and secondary cables
within the transformer cabinet. This
design provides easier switching and
cable movement where this issue
may be a concern.
The bushing insert meets all the
requirements of IEEE Standard 386™
– latest revision and is completely
interchangeable with mating products
that also meet IEEE Standard 386™.
When mated with a comparably rated
component, the bushing insert provides
a fully shielded and submersible
connection for loadbreak operation.
Figure 1.
25 kV Loadbreak Bushing Insert with latch indicator for applications in transformers,
switches, and other apparatus (left). Longer version for use whenever increased
clearance from the equipment faceplate and underground cables are required (right).
INSTALLATION
No special tools are necessary. The
insert can be installed by hand or with
the assistance of a torque tool. Using
the hex-broached base (see Figure 2)
and the LBI installation torque tool
(see Figure 4), consistent installation
can be easily achieved. Refer to

Expanded Range Loadbreak Elbow Connector
500-29
GENERAL
The Cooper POSI-BREAK™ Loadbreak
Elbow Connector is a fully-shielded
and insulated plug-in termination for
connecting underground cable to
transformers, switching cabinets and
junctions equipped with loadbreak
bushings. The Cooper POSI-BREAK
Elbow is a fully rated 200 A switching
device, designed in accordance to
IEEE Standard 386™ – latest revision.
The elbow design uses a state of the
art manufacturing process that creates
an insulated sleeve around the top of
the copper probe. It also provides a
layer of insulating rubber over the
conductive internal insert of the elbow.
This leaves the stress relieving feature
around the current interchange intact
and furnishes improved dielectrics and
increased strike distance. Together
these features provide superior
switching performance and reliability.
Cooper Power System Loadbreak
Elbows are molded using high quality
peroxide-cured EPDM rubber.
Standard kit features include a
coppertop connector, tin-plated copper
loadbreak probe with an ablative
arc-follower tip and a stainless steel
reinforced pulling-eye. An optional
capacitive test point is available for
use with fault indicators.
Figure 1.
25 kV Cooper POSI-BREAK Loadbreak Elbow Connector with test point provides
superior switching performance; also available without test point.
RETROFIT
The POSI-BREAK Elbow can be used
to upgrade or replace existing elbows
without having to re-strip the medium
voltage cable.
See installation sheet S500-10-1
(5000050751) for retrofit and installation details.
INSTALLATION
Cable stripping and scoring tools,
available from various tool manufacturers, are recommended for use
when installing loadbreak elbows.
After preparing the cable, the elbow
housing is pushed onto the cable.
The loadbreak probe is threaded into
the coppertop connector using the
supplied installation tool or an approved
equivalent. Use a hotstick to perform
loadmake and loadbreak operations.
See installation sheet S500-10-1

Rotatable Feedthru Insert
500-30
GENERAL
The Cooper Power Systems 25 kV
Rotatable Feedthru Insert is used to
provide dual bushings from a single
apparatus bushing well. It makes
converting radial-feed transformers to
feed-thru transformers and adding
in-line arrester protection both easy and
practical. Its patented, built-in torquelimiting ratchet prevents operators
from accidentally breaking bushing
well studs during installation. The
ratchet feature also allows the operator to rotate the feedthru insert 360°
to orient it in the best position for the
application. The bail assembly supplied
with the kit can be used to lock the
feedthru in position.
The Cooper Power Systems Rotatable
Feedthru Insert incorporates an all
copper current path and peroxide
cured EPDM rubber. It fully meets the
requirements of IEEE Standard 386™.
When mated with comparably rated
products, the insert provides a fully
shielded and submersible loadbreak
apparatus connection.
Cooper’s latch indicator ring, located
on the circumference of the bushing’s
collar, eliminates the guesswork of
loadbreak elbow installation on the
bushing interface. The bright yellow
ring provides immediate feedback to
determine if the elbow is properly
installed on the bushing. If the yellow
ring is completely covered by the
loadbreak elbow, it is fully “latched,”
if the ring is visible, the elbow can be
installed correctly before any problems
can occur.
INSTALLATION
Instruction sheet S500-13-1 details
the installation procedures that should
be followed and are included with each
insert. No special tools are required
for the proper installation of the insert.
A cleaned and lubricated insert is
simply placed in a bushing well and
turned in a clockwise direction. When
the torque-limiting ratchet releases,
giving an audible clicking, the insert
will be properly installed and tightened
to the correct torque. Continued
rotation in a clockwise direction allows
for a full 360° positioning to meet the
demands of the application. To remove
a de-energized insert simply rotate in
a counterclockwise direction.

GENERAL
The Cooper Power Systems 200 A,
25 kV Class Loadbreak Portable
Feedthru provides two internally bused
15.2/26.3 kV loadbreak interfaces
meeting all requirements of IEEE
Standard 386™ – Separable Insulated
Connector Systems. It is used in padmounted equipment, underground
vaults, and other apparatus to bypass
transformers, to test and ground circuits,
and to provide open point deadfront
lightning arrester protection when
used with the Cooper Power Systems
M.O.V.E.™ Arrester. Sectionalizing of
cable runs, to find and isolate cable
faults, is made easy when the portable
feedthru is used with 25 kV Class
(15.2/26.3 kV) loadbreak elbows and
other accessories meeting the requirements of IEEE Standard 386™. When
mated with comparably rated products,
the portable feedthru provides a fully
shielded, submersible, separable
connection for loadbreak operation.
The portable feedthru has a continuous
solid current path of all copper alloy
from finger contact to finger contact. No
aluminum current carrying components
are used. It also has an ablative arc
snuffer with excellent de-ionizing properties. The body is molded of high
quality peroxide-cured EPDM insulation and has a molded on peroxidecured semi-conductive EPDM shield.
Cooper’s latch indicator ring, located
on the circumference of the bushing’s

Cooper’s latch indicator ring, located
on the circumference of the bushing’s
collar, eliminates the guesswork of
loadbreak elbow installation on the
bushing interface. The bright yellow
ring provides immediate feedback to
determine if the elbow is properly
installed on the bushing. If the yellow
ring is completely covered by the
loadbreak elbow, the elbow is fully
“latched.” If the ring is visible, the
elbow is not fully installed, so the
operator can correct it before any
problems occur.
The portable feedthru is designed to be
installed in the parking stand mounted
on a transformer or other apparatus. It
is available with horizontal, vertical or

recommended for applications where
inadequate spacing is provided

Canadian Standards Edition
500-32C
GENERAL
The Cooper Power Systems 200 A,
25 kV and 28 kV Class Loadbreak
Junction provides two, three or four
loadbreak interfaces that are internally
bused together and meet all requirements of IEEE Standard 386™ —
Separable Insulated Connector
Systems. Loadbreak junctions are
used in pad-mounted apparatus,
underground vaults, and other apparatus to sectionalize, establish loops,
taps, or splices, and to facilitate apparatus changeouts. Sectionalizing a
cable run to find and isolate a cable
fault is made easy when a loadbreak
junction is used with 25 kV and 28 kV
Class loadbreak elbows and other
accessories meeting the requirements
of IEEE Standard 386™. When mated
with a comparably rated product, the
junction provides a fully shielded,
submersible, separable connection
for loadbreak operation.
The junction has a continuous solid
current path of all copper alloy. No
aluminum components are used. It also
has an ablative arc snuffer with superior
de-ionizing properties. The body is
molded of high-quality peroxide-cured
EPDM insulation and has a molded on
peroxide-cured semi-conductive
EPDM shield.
Cooper’s latch indicator ring, located
on the circumference of the interface
collar, eliminates the guesswork of
loadbreak elbow installation on the
interface. The bright yellow ring provides
immediate feedback to determine if the
elbow is properly installed on the
junction. If the yellow ring is completely
covered by the loadbreak elbow, the
elbow is fully “latched.” If the ring is
visible, the elbow is not fully installed,
so the operator can correct it before
any problems occur.
The loadbreak junction has an
adjustable stainless steel bracket for
mounting at various operating angles
on flat or curved surfaces, with up to
90° tilt in 10° increments. The solid
backplated channel provides strong,
rigid support of the junction for optimum
loadbreak operation. Parking stands
accommodate insulated standoff
bushings or portable feedthrus. Drain
wire clamps can each accommodate
two wires up to 1/0 stranded
(3/8" diameter).

200 A 25 kV Class Cooper POSI-BREAK™
Insulated Protective Cap
GENERAL
The Cooper POSI-BREAK™ Insulated
Protective Cap is an accessory device
designed to electrically insulate and
mechanically seal loadbreak bushing
interfaces. When mated to a loadbreak
product and the drain wire is attached
to ground, the Cooper POSI-BREAK
Insulated Protective Cap provides a
fully shielded, submersible insulating
cover for energized bushings. The cap
can be used for installations on
bushings, junctions or feedthru
devices that meet the requirements
of IEEE Standard 386™.
This cap design uses a state-of-the-art
manufacturing process that creates an
insulated sleeve around the top of the
copper probe. It also provides a layer of
insulating peroxide-cured EPDM rubber
over the peroxide-cured conductive
internal insert of the cap. This added
insulation greatly increases the strike
distance and improves the dielectrics.
This increased performance eliminates
partial vacuum flashovers while
maintaining the stress relieving
Faraday Cage that is critical to long
term field performance.
INSTALLATION
No special tools are required. A
shotgun stick tool is used to place
the protective cap on an exposed
bushing interface. Refer to
Installation Instruction Sheet
S500-21-1 (5000050558) for details.

Insulated Standoff Bushing
500-40
GENERAL
The Cooper Power Systems 200 A,
25 kV Insulated Standoff Bushing
meets the full requirements of IEEE
Standard 386™ — Separable Insulated
Connector Systems and provides a
single loadbreak interface made of high
quality peroxide-cured EPDM rubber. It
is used to isolate and sectionalize
energized cable in padmounted
cabinets, underground vaults, and other
apparatus. Temporary or permanent
parking of energized 200 A,15.2/26.3 kV
loadbreak elbow connectors that
conform to IEEE Standard 386™ is
simplified with use of the insulated
standoff bushing.
The insulated standoff bushing is
designed to be installed in the parking
stand mounted on a transformer or
other apparatus. A grounding lug is
provided on the standoff bushing
bracket for attachment of a drain wire
to ensure deadfront construction. When
mated with a comparably rated product,
the insulated standoff bushing provides
a fully-shielded, submersible, separable
connector for energized operation.
The standard insulated standoff bushing has a stainless steel eyebolt with
a brass pressure foot. The molded
peroxide-cured EPDM rubber body is
bolted to a stainless steel base bracket
using a galvanized steel holddown ring.
A completely stainless steel bracket
assembly is available for extremely
corrosive environments.
Cooper’s latch indicator ring, located
on the circumference of the bushing’s
collar, eliminates the guesswork of
loadbreak elbow installation on the
standoff bushing. The bright yellow
ring provides immediate feedback to
determine if the elbow is properly
installed on the bushing. If the yellow
ring is completely covered by the
loadbreak elbow, it is fully “latched,” if
the ring is visible, the elbow can be
installed correctly before any problems
can occur.
INSTALLATION
No special tools are required. A hotstick tool is used to place the standoff
bushing in the parking stand on the
front plate of the apparatus. Refer to
Installation Instruction Sheet
S500-22-1 (5000050573) for details.

Premolded Cable Jacket Seal
500-90
DESCRIPTION
The Cooper Power Systems RTE®
Cable Jacket Seal makes sealing
underground jacketed cable quick
and easy. The sealing device is
designed for use when installing a
200 A elbow or another similar
termination on jacketed concentric
neutral cable, to seal the jacket
stripback from contamination or
moisture ingress. The Cable Jacket
Seal is molded from field-proven,
in-house mixed EPDM semiconductive rubber.
The elastic design of the cable seal
allows total flexibility in positioning it
on the cable. It can also be repositioned on the cable, or completely
reused after its initial installation –
something that is not possible with
either coldshrink or heatshrink
alternatives.
When installed in conjunction with
the supplied mastic, the Cable
Jacket Seal protects the cable from
airborne contaminants and water.
This allows installation in high
moisture or flooded environments
without the fear of neutral corrosion,
or moisture ingress into the cable,
that would defeat the purpose of the
cable jacket.
The rugged and reliable nature of
the premolded Cable Jacket Seal
has been verified by its successful
completion of Cooper Power
Systems’ accelerated aging and
sealing test as well as a mechanical
Creep Resistance test that
measures the seal's ability to
withstand mechanical damage
during and after installation.
INSTALLATION
No special tools, heat source or hand
taping skills are required to install the
Cable Jacket Seal. The cable is prepared according to the instructions
provided with the elbow termination.
Concentric neutral strands are
bound down and twisted to form

a single conductor for grounding the
cable. Mastic tape, supplied in the
sealing kit, is applied beneath and
over the concentric neutrals. The
cable seal is then pulled down over
the cable.
Using the top pull tabs, the seal is
pulled back on to itself far enough
to install the elbow or terminator
onto the cable. Once the elbow is
installed, the cable seal is pulled
back up and over the cable
entrance of the elbow, completing
the sealing operation. Maximum
length of area to be sealed should
not exceed 2.5 inches.
