Multi-tap separable splice assembly instructions
ote:N Use only the symmetrical aluminum or copper
stud in separable splice applications. Do not use
the non-symmetrical T-OP™ II stud.
•
To assemble a separable splice prepare all cable following
Steps #2 through #11.
ote:N Before any component is installed, clean and
lubricate, using the grease provided or an
approved alternate, all mating interfaces (i.e.
T-bodies, insulating plugs, connector plugs, and
cable adapters).
•
Obtain first insulating plug, if a stud is not factory
installed, hand thread a .625" stud into the insulating plug
and torque to 55 ft-lbs using a crows foot type wrench
(1/2" open end) and torque wrench. Insert the insulating
plug into the first T-body, lining up the hole in the
compression connector with the .625" stud.
•
Insert the connecting plug into the open interface of
the first T-body and hand tighten to the .625" stud of the
insulating plug.
•
Secure the connecting plug by inserting a 5/16" hex
style wrench (HD625, T-wrench, or customer supplied
alternate), into the hex hole at the base of the connector
plug threads. Use a torque wrench to tighten the
insulating plug to 55 ft-lbs. Refer to Figure 17.
•
Insert the interface of the connecting plug into the
interface on the second T-body.
•
To assemble additional splice taps, obtain a second
connecting plug, if stud is not factory installed, hand
thread a .625" stud into one end and torque in to 55 ft-lbs.
•
Install the stud end of the connector plug into the open
interface of the second T-body. Hand thread the connector
plug to the previously installed connector plug. Secure
the first insulating plug with a 1" wrench. Insert a 5/16"
hex shaft with socket drive tool (HD625, or customer
supplied alternate), into the 5/16" hex hole at the base of
the connector plug threads. Connect a torque wrench to
hex shaft tool, while keeping first insulating plug secure,
torque the second connector plug to 55 ft-lbs. Refer to
Figure 18.
•
Repeat the assembly procedure used to install the
second connector plug and T-body for each additional
splice tap.
•
After all connecting plugs are installed, obtain the second
insulating plug, if stud has not been factory installed,
hand thread a .625" stud into the insulating plug and
torque to 55 ft-lbs.
•
Install the second insulating plug, with stud, into the
open interface of the last T-body. Hand thread the
insulating plug into the connector plug.
•
Secure the first insulating plug using a 1" wrench. Using
a 1" socket on a torque wrench tighten the second
insulating plug to 55 ft-lbs. Refer to Figure 31.
•
Clean and lubricate the inner surface of two insulating
plug caps with the lubricant supplied.
•
Push the caps onto the insulating plugs until they snap
into place.
•
Connect one strand of the cable concentric neutral wire
to the tie-off tab of each T-body.
ote:N If splice is disassembled, all connector plugs and
insulating plugs should be removed completely,
cleaned, regreased, and reassembled following
the above procedure to ensure connection points
are properly torqued.
