Wire Splicing
Splice wire to motor leads using only copper wire for
connections to pump motor and control box.
1. Tapered splice (Wire sizes No. 8 and larger):
A. Cut motor lead staggering lead and wire length so
that second lead is 2” longer than first lead and third
lead is 2” longer than second.
B. Cut off power supply wire ends. Match colors and
lengths of the wires to colors and lengths of motor leads.
C. Trim installation back 1/2” from supply wire and motor
lead ends.
D. Insert motor lead ends and supply wire ends into butt
connectors. Match wire colors between supply wires and
motor leads.
E. Using crimping pliers, indent butt connector lugs to
attach wire.
F. Cut electrical “Scotchfil™” or equivalent insulation
putty into three equal parts and form tightly around butt
connectors. Be sure Scotchfil™ overlaps insulted part of
wire.
G. Using #33 Scotch™ or equivalent tape, wrap each
joint tightly; cover wire for about 1-1/2” on each side of
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 tightly wound tape is the only means
of keeping water out of splice, efficiency of splice will
depend on the care used in wrapping the tape.
NOTICE: For wire sizes larger than No. 8, use soldered
joint rather than Scotchfil™ putty.
2. Heat shrink splice
[for wire sizes #14, 12 and AWG (2,3 and 5mm)]
A. Remove 3/8” insulation from ends of motor leads and
power supply wires.
B. Put plastic heat shrink tubing over motor leads
between power supply and motor.
C. Match wire colors and lengths between power
supply and motor.
D. Insert supply wire and lead ends into butt connector
and crimp. Match wire colors between power supply and
motor. Pull leads to check connections.
E. Center tubing over butt connector and apply heat
evenly with torch (match or lighter will not supply enough
heat).
NOTICE: Keep torch moving. Too much concentrated
heat may damage tubing.
3. Mechanical Splice Kit with plastic insulators (for 14, 12
and 10 Gauge AWG Wire (2, 3 and 5mm):
A. Cut motor leads staggering lead and wire length so
that 2nd lead is 4” (101.6mm) longer than 1st lead and
3rd lead is 4” (101.6mm) longer than second.
B. Cut wire ends matching colors and lengths of wires
between power supply and motor.
C. Trim insulation back 1/2” (12.7mm) from power supply
wire and motor lead ends.
D. Unscrew plastic caps from insulators. Place a cap
and neoprene gasket sleeve on each wire to be spliced.
E. Slide insulator body onto one wire end.
F. Insert wire end into butt connector and crimp. Match
wire colors between power supply and motor
G. Center insulator body over splice and slide gasket
sleeves into body as far as they will go. Screw caps
onto insulator body and tighten by hand for a strong,
waterproof splice.
Power Supply Wire Installation
1. To test submersible, momentarily (no more than 5
seconds) connect it to proper power supply. Power supply
frequency and voltage must match motor name plate
frequency and voltage to within ±10%.
2. Fasten power supply wire leads securely to pump
discharge section; leave 4-5” (100-125mm) of slack in leads
at this point. Securely fasten leads to plastic pipe within
6” (150mm) of the pump discharge section. Use centering
guides to protect wire and pipe from rubbing well casing.
3. Connect copper ground wire to motor bracket. Ground
wire must be as large as wires supplying current to motor.
Consult current Canadian Electrical Code and local codes
for grounding information.
4. Most 4” pumps have an eyelet on the pumps discharge
for attaching a rope to assist in lowering into and pulling the
pump from the well. Attach a nylon rope of adequate length
to eyelet
5. Do not use submersible power supply wires supplied by
pump manufacturer to lower or lift pump. When lowering
pump into well use only the rope and/or discharge pipe,
secure supply wires to discharge pipe at 10 ft. (3M)
intervals with Scotch™ #33 or equivalent electrical tape.
DO NOT damage pump wires.
NOTICE:
To avoid dropping pump down well or damaging wires or
splices, NEVER allow pump wires to support weight of
pump.
