WIRE SPLICING
Splice wire to motor leads. Use only copper wire for connections to pump motor and control box.
TAPED SPLICE (Wire sizes No. 8 (8.4mm
2
) and larger):
1.
Cut off the motor leads. Stagger the lead and wire length so that second lead is 2 in. (50 mm) longer than first lead and third lead
is 2 in. (50 mm) longer than the second.
2.
Match colors and lengths of wires to colors and lengths of motor leads.
3.
Trim insulation back 1/2 in. (13 mm) from the cable ends and motor lead ends.
4.
Insert motor lead ends and cable ends into a butt
connector. Match the wire colors between the supply wires
and motor leads.
5.
Using crimping pliers, indent the butt connector lugs.
6.
Cut “Scotchfil” electrical insulation putty into three equal parts and form tightly around the butt connectors. Ensure the Scotchfil
overlaps the insulated part of the wire.
7.
Using #33 Scotch tape, wrap each joint tightly. Cover the
wire for about 1-1⁄2 in. (38 mm) on each side of the joint.
Make four passes with the tape. When finished you should
have four layers of tape tightly wrapped around the wire.
Press edges of tape firmly down against the wire.
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, (7 mm
2
) use a soldered joint
rather than Scotchfil putty.
HEAT SHRINK SPLICE (For Wire Sizes #14, 12, and 10 AWG, or 2, 3, and 5.5 mm
2
)
1.
Remove 3/8 in. (9.5 mm) insulation from the ends of the motor leads and power supply wires.
2.
Put plastic heat shrink tubing over the motor leads
between the power supply and motor.
3.
Match wire colors and lengths between the power supply and motor.
4.
Insert the supply wire and lead ends into the butt
connector and crimp. Match the wire colors between the
power supply and the motor. Pull the leads to check
connections.
