Installation Instructions

151GP

Deadbreak Grounding Plug

CONTENTS: Grounding Plug (complete with stainless steel mounting hardware), Hold ---down Bail Assembly,

Lubricant, Installation Instructions

The 151GP is designed to ground a cable terminated with a (K)154LR or 156LR deadbreak elbow.

CAUTION: Deadbreak: All associated apparatus must be de---energized during installation and operation of this assembly.

DANGER

All apparatus must be de--energized during installation
or removal of part(s). For loadbreak products follow
operating instructions. All deadbreak connectors must
be de--energized before operating. All 200A deadbreak
connectors must be mechanically secured with bails
when connected.

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.

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

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

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

Connect the flexible lead of the grounding plug to system
ground leaving enough slack to operate with a hotstick.

Remove protective shipping cap and clean the mating
interface of the grounding plug. Lubricate this surface. Use
only the supplied lubricant or ELASTIMOLD approved
lubricants. DO NOT SUBSTITUTE. Other lubricants may be
harmful to this product and its mating products. Always
replace the protective cap when the grounding plug is not
in use.

STEP 2

Attach hotstick to the eye of the grounding plug carriage
assembly. Slide carriage assembly into parking stand.
Push bail out of way so it willnot interfere with placement of
deadbreak elbow connector.

STEP 3

Follow the applicable instructions to make a voltage test
before removing the deadbreak elbow connector from the
apparatus bushing. Remove elbow connector from
apparatus bushing and place on grounding plug. DO NOT
REMOVE IF VOLTAGE TEST INDICATES CONNECTOR IS
ENERGIZED.

STEP 4

BAIL MUST BE USED TO SECURE DEADBREAK ELBOW.
Position the bail eyebolt directly over the bail locater on the

elbow. Tighten down on bail locater by turning eyebolt with
the hotstick in a clockwise direction. If entire assembly
(grounding plug and elbow) is to be removed from parking
stand, attach hotstick to eye of carriage assembly, remove
from parking stand and place where desired. To return
elbow connector to apparatus bushing, simply reverse the
operational sequence.

VOLTAGE TEST

The ELASTIMOLD deadbreak elbow connector is equipped with an integral capacitance test point that 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 and lubricate the inside surface of the cap with silicone grease and

replace it on the test point.
