12. Ensure mastic is significantly thicker on one side of
the flat sides of both cables. Align ends of cable and
place flat side of both cables together with the sides
with the thicker mastic tape in contact. Work mastic
with fingers and stretch mastic until there are no voids
between the cables and there is a continuous strip of
mastic around both cables.
13. Tightly twist the bus wires from each side together.
14. Bend one bus wire up and the other down to create
more room for crimp tool. Insert a blue heat shrink
crimp over each bus wire bundle. Ensure the exposed
bus wire bundles are completely covered by the
blue heat shrinks. If blue heat shrinks do not cover
the exposed bus wire bundles, remove more of the
conductive core.
15. Ensure the exposed bus wires are inside the metal
crimp portion of the blue heat shrinks.
16. Using crimp tool, crimp the blue heat shrinks down so
that they hold the bus wire bundles in place.
17. Using cable ties, secure the two cable lengths
together 3" and 6" away from the end of the braid.
18. Slide the three black heat shrinks (3½" long, 8" long,
8½" long) down the third cable length.
19. Position the third cable length so that the ground
braid is on the same side and the two cable lengths.
20. Insert the bus wires of the third cable unto the blue
heat shrinks. Ensure the exposed bus wires are
completely covered by the blue heat shrinks.
21. Ensure the exposed bus wired are inside the metal
crimp portion of the blue heat shrinks.
22. Bend one bus wire up and the other down to create
more room for crimp tool. Using crimp tool, crimp the
blue heat shrink down so that they hold the bus wires
in place.
23. Slide the 3½" ling black heat shrink to cover the
crimps and partially cover the inner jacket on both
ends of the splice connection. Ensure the ground
braids are not inside the heat shrink. Using heat gun,
fully heat shrink the tube until inner sealant appears
and no more shrinkage is apparent.
24. Slide the metal crimp sleeve onto the ground braid.
Bend the cables together to allow some slack so that
all three ground braids can easily overlap.
25. Slide the metal crimp sleeve over the overlapped
ground braids and crimp twice to make sure the
connection is secured. Use the 14AWG slot on the
crimp tool (Tyco AD1522 or equivalent) to crimp the
metal crimp sleeve. Lay the ground braid flat on top of
the connection to mark the overlap.
NOTE: Nuheat recommends conducting continuity
testing at this point of the installation.
26. Slide the 8" long black heat shrink over the entire
splice connection so that it covers the mastic strip
on both sides. The heat shrink should overlap the
splice connection by 1½" on both sides of the splice
connection. Using heat gun, fully heat shrink the tube.
27. Wrap one end of the connection with the 4" long
aluminum tape ½" away from end of heat shrink tube
toward center of connection. Repeat if necessary to find
best lay angle to ensure mastic tape under the heat
shrink is fully covered by aluminum tape. Smooth tape
with fingers to ensure no sharp edges.
28. Slide the 8½" long black heat shrink over entire splice
connection so that it overlaps the previous heat shrink
equally on both sides. Using heat gun, fully heat shrink tube.
