STEP4 CABLE ADAPTER

Bevel the end of the cable insulation at a 45_ angle, approximately 1/4” (6mm) back. Thoroughly clean, then lubricate cable
insulation always working toward semi--- con shield. Install cable adapter, small end first, until it is flush with the edge of the
tape marker.

STEP5 CONDUCTOR

Remove any protruding cable insulation by cutting it even
with the end of the cable adapter. Do not cut or nick the
cable adapter or the conductor. The length of exposed
conductor should be between 4--- 3/8” -- 4 -- 1 1/16”
(111mm--- 119mm). Otherwise redo assembly.

Copper Conductor: Fully insert conductor into compression Lug.
Aluminum Conductor: Wire brush conductor and immediately fully insert conductor into compression lug.

Measure the “CheckDimension” before crimping. Dimensionshould be less than 6--- 1/2”. Otherwise redo assembly. Before
making the first crimp, align the flat portions of the compression connector by using a 5/8” bolt as a temporary locater while
crimping. Hold the compression connector in the proper position and make the first crimp connection 3--- 1/2” from the open
end of the compression fitting at the mark indicated on the connector.

STEP7

Rotate each successive crimp 180_ to prevent bowing.Carefully wipe excess inhibitor from theoutside of the connector and
from the cable insulation. Check to ensure that the connector end is6 ---1/2” to 7--- 1/4” . Remove sharp flash, if any, from the
crimp before inserting into the vault stretcher body.

STEP8

1. Lubricate the inside of the vault stretcher body and the outside of the cable adapter. Using a rotating motion, slip the
body onto the cable adapter. Make sure the compression lug is aligned to seat with the inside mating portion of the
vault stretcher. The compression lug should be pushed into the vault stretcher until it cannot advance further. The
base of the adapter should still be aligned with the marking tape.

2. To insert the opposite cable into the other side of the vault stretcher, the vault stretcher and compression lug must be
pushed sideways until the compression lug enters the open end of the vault stretcher body.

3. Slowly push both units toward their final alignment, making sure the lubricated adapter is sliding into proper position
in the vault stretcher. Check the location of the compression lug through the viewing hole of the vault stretcher. When
compression lug is fully seated, make sure that both cable adapters are still flush with tape markers. If not, reposition
cable adapters. Remove tape markers.

STEP9

NOTE: A special stud (650VSA) 1/2” longer than the standard stud must be used with the vault stretcher.

1. DO NOT connect or disconnect mating products while energized. DO NOT energize while disconnected. Remove
protective caps from the vault stretcher and the mating part. Hand tighten stud, supplied with vault stretcher, into one
mating part. Clean and lubricate the vault stretcher and the mating part with lubricant supplied.(Keep surfaces

of vault stretcher and mating part clean).

2. Clean and lubricate the mating part for the opposite end of the vault stretcher. Insert the mating part into the elbow.
Engage the threads and hand tighten. Torque mating part according to the instructions supplied with the mating part.
All mating parts must be operated in accordance with their operating instructions.

STEP 11 GROUNDING CONCENTRIC NEUTRAL CABLE

Insert one end of a piece of wire with ampacity at least equivalent to No. 14 AWG copper through grounding eye and twist to
make a small loop. Repeat for other grounding eye. DO NOT damage the eyes. Connect wires to ground using suitable
connectors.
