Installation & Operating Instructions

164FT

FEED--THRU/GROUNDING DEVICE

CONTENTS: Feed--thru Body Complete with Mounting Hardware, Lubricant, Operating Instructions.

IMPORTANT: Read these instructions and the Loadbreak Elbow Operating Instructions (IS--167/168LR COMPLETELY

before operating connectors.

The feed--thru can be used for the following functions: A) A junction point, B) A grounding point. To use the feed--thru as a
junction point, follow steps 1 to 7. To use the feed--thru as a grounding point, follow steps 1 to 5 and 8 to 9. A yellow band
provides indication of full elbow seating. This product is identified by a yellow ID washer attached to the eyebolt.

DANGER

All apparatus must be de--energized during installation
or removal of part(s) except for test point caps and
indicators that can be installed and operated
energized.

After installation loadbreak products can be operated
energized per operating instructions. All deadbreak
connectors must be de--energized before operating.

All apparatus must be installed and operated in
accordance with individual user, local, and national
work rules. These instructions do not attempt to
provide for every possible contingency.

Do not touch or move energized products.

“Loadbreak connectors must be operated with a full
insulated “hotstick” type live -- line tool.” Consult the
company’s safe work practices for the required
live--line tool length.

FOR MORE INFORMATION ON PARTS, INSTALLATION RATINGS AND COMPATIBILITY, CALL THE NEAREST ELASTIMOLD OFFICE.

Excess distortion of the assembled product may result
in its failure.

Inspect parts for damage, rating and compatibility with
mating parts.

This product should be installed only by competent
personnel trained in good safety practices involving
high voltage electrical equipment. These instructions
are not intended as a substitute for adequate training or
experience in such safety practices.

Failure to follow these instructions will result in
damage to the product and serious or fatal injury.

If this product is supplied with a protective shipping
cover(s), remove this shipping cover(s) and replace
with the appropriate HV insulated cap(s) or
connector(s) before submerging or energizing the
circuit.

IMPORTANT

1. Check contents of package to ensure they are complete
and undamaged.

2. Check all components to ensure proper fit with cable
and/or mating products.

STEP 1

Grounding -- Insert ground lead into the grounding lug
provided on themounting hardware and tighten lug. Ground
lead should be No. 14 copper wire or equivalent. Connect
the opposite end of the lead to ground, leaving enough slack
to operate with a hotstick.

3. Read entire installation instructions before starting.

4. Have all required tools at hand and maintain cleanliness
throughout the procedure.

STEP 2

Remove the protective caps from the bushings of the
feed--thru.
PROTECTIVE CAPS MUST NOT BE ON THE BUSHINGS
OF THE FEED--THRU WHEN THE FEED--THRU IS
BEING USED. When the feed--thru is not in use, the
protective caps should be placed on the bushings of the
feed--thru to protect them from dirt and other contaminants.
Clean the bushing surfaces and lubricate them with the
lubricant supplied. DO NOT SUBSTITUTE. Other
lubricants may be harmful to this product and its mating
product(s).

STEP 3

Attach feed--thru eye firmly to hotstick.

Using a hotstick, slide feed--thru onto parking stand. Unlock
hotstick and back off, to allow space for eyebolt to be
tightened. Tighten eyebolt by rotating hotstick clockwise
until snug. DO NOT OVERTIGHTEN. Release hotstick.

STEP 5

Remove one loadbreak elbow from its apparatus loadbreak bushing following the applicable loadbreak operating instructions
(IS--165/166LR). Using a hotstick, firmly attached to the elbow, insert the probe tip into one feed--thru until the first slight
resistance is felt. Immediately push the elbow home with a fast, firm straight motion which will engage the internal lock on the
mating interfaces.

STEP 6

Remove second loadbreak elbow, following the applicable
loadbreak operating instructions (IS--165/166LR). Using a
hotstick, firmly attachedto the elbow, insert the probe tip into
the remaining feed--thru until the first slight resistance is felt.
Immediately push the elbow home with a fast, firm straight
motion which will engage the internal lock on the mating
interfaces.

STEP 7

When it is desired to re--connect the elbow(s) to the apparatus bushing(s), first make certain no faults exist on the system.
To return the loadbreak elbow to the apparatus bushing, reverse the operational sequence, following the applicable
loadbreak--loadmake operating instructions.

FOR GROUNDING POINT APPLICATION FOLLOW STEPS 8 TO 9

IMPORTANT: Do not insert grounding elbow into Feed--Thru unless circuit has been tested “De--Energized”.

STEP 8

Ensure that the system is de--energized with either of the following procedures.

1. Check the capacitive test point on the loadbreak elbow for voltage, with an appropriate voltage detection device.

CAUTION: The voltage test point is a capacitance device; it is notdirectly connected to the conductor. It requires the

use of specially designed instruments. Do not use conventional voltage measuring requirements; NO
INDICATION WILL BE OBTAINED.

2. Remove existing elbow or insulated cap from the bushing with a hotstick following the applicable loadbreak operating
instructions (IS--165/166LR, IS--273/274LR or IS--375/376LR). Firmly tighten a hotstick to the 370TR test rod operating
eye. Insert the test rod into the bushing. Using a meter capable of direct reading the system voltage, check the test rod
disc for voltage. Remove test rod.

IMPORTANT: If voltage is indicated by either of the two preceding procedures, do not proceed without De--energizing

the system.

IMPORTANT: The hotstick eye and disc of the test rod are not insulated; be careful to keep them clear from ground until

tested ”de--energized”.
