Installation Instructions.
The 252LRJS is designed to terminate UD jacketed and non--jacketed cable having concentric neutral wires or copper tape
shielding. The elbow provides a voltage test point and an operating interface for connecting to an 12/20 (24)kV 250ampere
deadbreak bushing or accessory device. Designed with a fold down extension on the cable entrance for sealing to the jacket of
jacketed cable. When other types of UD cable are to be terminated, an appropriate Elastimold cable shield or grounding device
must be used.
DANGER

STEP 1 CABLE TRAINING
1. Train cable to ensure slack for ease of operation.
2. An extra length of concentric neutral wires or grounding braid is needed to faciliate hotstick operation and connection of
the neutral to the tank ground. This can be accomplished by either of two methods: 1. Tape mark the bushing centerline
and pull extra cable to 24--26” beyond the bushing centerline; 2. Proceed to Step 1.D., connect the neutral wires to the
tank ground with a jumper or braid.
3. Unwrap the neutral wire back past the bushing centerline.
4. Cut excess cable squarely at the centerline of the bushing.
STEP 2A CABLE PREPARATION CONCENTRIC NEUTRAL WIRES
1. Wrap one strip of mastic, stretching slightly, around jacket.
2. Bend all of the neutral wires straight back over the mastic
and along the cable. Press the wires into the mastic.
3. Wrap the second strip of mastic completely around the
outer jacket, overlapping the neutral wires imbedded into
the first mastic strip. Use the third strip of mastic, if needed,
to build--up the outer diameter in the area of the first mastic
location. Cover all mastic with vinyl tape.
4. Remove insulation shield and insulation from the cable end.
Cut squarely taking care not to nick conductor.
5. Wire brush bare aluminum conductors and immediately place
compression lug over bushing. Rotate to spread inhibitor.
Position compression lug so the CONTACT THREADED
HOLE ALIGNS WITH THE BUSHING BORE. (Refer to crimp
chart packaged with compression lug for recommended crimp
tool information.) Start crimp at the crimp line mark. Rotate
180_each successive crimp. Carefully wipe excess inhibitor
from the outside of the lug and cable.
6. Remove insulation shield as shown. Bevel insulation end
1/8” max.
7. Thoroughly clean insulation to remove all traces of dirt or
excess inhibitor.

STEP 2B CABLE PREPARATION FOR JACKED COPPER TAPE SHIELD CABLE
1. Cut the cable squarely at the centerline of the bushing.
2. Remove 8--1/2” (209mm) of the outer jacket.
3. Remove 7” (178mm) of the copper tape shield.
4. Wrap conductive copper tape around the edge to keep
the copper tape shield in place. Install the desired
product per the manufacturer’s instructions included
with the product. Apply one wrap of mastic, as shown.

5. Slightly flare the end of the braid with the solder block and
place it on the copper shield, flush against the cable jacket. Solder Block

6. Wrap the spring coil around braid and cable two
complete turns. Spring Coil
7. Bend braid back over the spring and wrap the remainder
of the spring coil around the braid and cable. Hand
tighten spring coil and secure the end of the coil with
a short piece of copper tape. Be sure the solder block of
braid is centered on top of the mastic tape.
8. Apply mastic over the braid, as shown.
9. Over wrap mastic with two half--lapped layers of vinyl tape.
10. Wrap the third piece of mastic around the cable entrance
of the connector being used. Over wrap mastic with two
half--lapped layers of vinyl tape.

11. Remove insulation shield and insulation from the cable
end. Cut squarely taking care not to nick conductor.
12. Position compression lug so the CONTACT THREADED

recommended crimp tool information.) Start crimp at the
crimp line mark. Rotate 180_each successive crimp.

STEP 3 ELBOW ASSEMBLY
1. Clean the cable insulation and inside the elbow housing
and lubricate with the lubricant supplied. DO NOT
SUBSTITUTE. Other lubricants may be harmful to this
product or its mating product(s). Keep insulation clean
of dirt and grime.
2. Slide the elbow connector onto the cable with a
back and forth twisting motion. Wipe off all excess
lubricant.
3. Align elbow with compression lug’s threaded hole.
4. Thread probe into lug by hand, taking care not to
cross--thread. Tighten with wrench until wrench
bends.

STEP 5 CONCENTRIC NEUTRAL CONNECTION OR COPPER TAPE
1. Pull the hood over the concentric neutral seal area on
the cable by pulling the tabs and/or rolling the seal
down.
2. Using a separate copper wire (No. 14 AWG / 2.5mm)
or equivalent, insert one end through the grounding eye
on the elbow. Twist tightly taking care not to damage
the eye.
3. Connect copper braid and wire to ground using
appropriate connector. Provide adequate slack in
wires for elbow operation.

STEP 6 CONNECT ELBOW AND BUSHING PLUG
1. Clean the receptacle portion of the elbow connector and the mating bushing and lubricate with the lubricant supplied.
LUBRICATE ONLY IF THE TRANSFORMER AND ELBOW ARE KNOWN TO BE DE--ENERGIZED.
2. Use a fully insulated hot stick to place the elbow on the bushing. DO NOT OPERATE BY HAND. DO NOT SEPARATE IF
ENERGIZED.
Hotstick
Clean and Lubricate only if known to be de--energized
STEP 7 BAIL ELBOW
1. Pull hold--down bail up over the crown or top of elbow
so that the eyebolt on the bail is directly over the
operating eye.
2. Tighten down on elbow locator by turning eyebolt in a
clockwise direction. Adjust the nut on the eyebolt
until it allows the eyebolt to seat securely in the locator.
The nut should act as a stop to prevent the eye
bolt from applying excessive force on the elbow. Once
the nut is in final position, it will not have to be
readjusted when removing and replacing elbow.
Operating Eye
VOLTAGE TEST
ELASTIMOLD connectors equipped with an integral capacitance test point can be used to establish whether or not the
circuit is energized. When using the test point, complete the following steps:
1. Remove test point cap with a hotstick. When removing cap, PEEL OFF AT AN ANGLE rather than pulling directly in line
with the test point assembly.
2. WARNING: THE VOLTAGE TEST POINT IS A CAPACITANCE DEVICE, IT IS NOT DIRECTLY CONNECTED TO THE
CONDUCTOR. Do not use conventional voltage measuring equipment. Follow the manufacturer’s directions for the
meter that is used. Test with a suitable sensing device, made for use with separable connectors manufactured with
capacitive test points, to determine if cable is energized. Contamination, moisture, dirt, etc. around the test point or use
of the wrong measuring equipment can provide a false “no voltage” indication on an energized elbow. To prevent
serious or fatal injury treat the elbow as energized until the “no voltage” test point indication is confirmed by other means.
3. After voltage detection has been made, clean the inside surface of the cap and lubricate with lubricant supplied;
replace it on the test point.
