RGS Self-Regulating Heating Cables
Splice and Tee Kit with End Termination Kit

RGSTM-SFK Power Connection and End Termination Kit
Tools Required for Installation
Crimper/cutter, flat-blade screwdriver,
and utility knife
Step 2: Cut overjackets back a distance
of 3" (70 mm).
Kit Contents
(1) Splice/Tee, (1) End Termination
Step 3: Separate braids and twist into pigtails. Carefully cut primary jackets back
2" (50 mm).
Splice and Tee Connection
Step 1: Allow 12" (30 cm) of extra length
for each heating cable at the connection
point.
Step 4: Skive outer matrix material from
conductors with utility knife.
Step 5: Peel exposed wires back from
center matrix and cut center matrix away,
leaving bare conductors.
Step 6: wrap black mastic around each
cable beginning at a distance fo 1"
(25 mm) back from the pigtail (overjacket).
Step 8: Stack the two (or three cables in
the case of a tee) together and tighten
down with two standard tie wraps at
8" (20 cm) and 10" (28 cm) respectively
from the exposed bus wire end.
Step 7: Squeeze
RTV into the
silicone rubber
boots and slide
over cable ends.
Step 9: Twist all the pigtails together. Slide
the large un-insulated lug over the braid
ends in close proximity to the cables and
then crimp. Trim off any extra braid. Bend
pigtail back so that the crimp lug lies down.

INSTALLATION INSTRUCTIONS
Step 10: Wrap black electrical tape around
the cables and over the crimped lug.
Step 13: Slide the 8" (20 cm) heat shrink
tube over the connection past the mastic
approximately 1" (25 mm) and shrink
from mastic end back toward the terminated splice end.
Step 11: Twist the bus wires of one side
of the cables together and repeat with the
other side, making sure that both wires
from any one cable do not get twisted together. Crimp insulating caps on each leg.
Step 14: Pinch heated shrink end with a
pair of pliers until the encapsulant cools
and seals.
Step 12: Wrap mastic tape around each
terminated leg and insulation cap.
Step 15: Fold the splice back on itself to
one of the outside cables and secure with
a tie wrap. For roof and gutter applications
secure the splice up and away from the
bottom of the gutter.
End Termination . . .
Step 16: Cut back overjacket 0.5"
(12 mm).
Step 19: Slide the end cap on the end of
the cable until fully seated.
Step 17: Trim ALL of the braid strands
back to the overjacket with scissors.
Step 20: Put a small amount of RTV into
the opening of the larger over-cap.
Step 18: Fill the smaller end cap with RTV.
Step 21: Slide
the over-cap
over the end cap
until fully seated.
