CABLE SPLICING:

1. Splice cable to motor leads. Use one of the
three methods outlined below. Use only
copper wire for connections to pump motor
and control box.
A. Taped splice (Wire sizes No. 8 (8.4mm
and larger):
1. Cut off motor leads. Stagger lead and
wire length so that 2nd lead is 2"
(50mm) longer than 1st lead and 3rd
lead is 2" (50mm) longer than second.
2. Cut off cable ends. Be sure to match
colors and lengths of wires in drop cable
to colors and lengths of motor leads.
3. Trim insulation back 1/2" (13mm) from
cable ends and motor lead ends.
4. Insert motor lead ends and cable ends
into butt connectors (see Figure 4). Be
sure to match wire colors between drop
cable and motor leads.
5. Using crimping pliers (Figure 7), indent
butt connector lugs (see Figure 5) to
attach wires.

6. Cut "Scotchfil" electrical insulation putty
into 3 equal parts and form tightly
around butt connectors. Be sure
scotchfil overlaps insulated part of wire.
7. Using #33 Scotch tape, wrap each joint
tightly; cover wire for about 1-1/2"
(38mm) on each side of joint. Make four
passes with the tape. In other words,

when finished you should have four
layers of tape tightly wrapped around
the wire. Press edges of tape firmly
down against the wire (see Figure 8).
NOTICE: Since the tightly wound tape is
the only means of keeping water out of
the splice, the efficiency of the splice
will depend on the care used in
wrapping the tape.
NOTICE: For wire sizes larger than #8,
(8.4mm
Scotchfil putty (see Figure 6).
B. Heat-shrink splice (For wire sizes #14, 12
and 10 AWG, or 2, 3, and 5.5mm
1. Remove 3/8" (10mm) insulation from
ends of motor leads and drop cable
wires.
2. Put plastic heat shrink tubing over motor
leads.
3. Match wire colors and lengths in drop
cable to wire colors and lengths of
motor leads.
4. Insert cable and motor wire ends into
butt connectors and crimp (See Figures
4 and 5). BE SURE to match wire colors
between drop cable and motor leads.
Pull leads to check connections.
5. Center tubing over butt connector and
apply heat evenly with a torch (a match
or lighter will not supply enough heat).
