4. Splicing the Motor Cable
If the splice is carefully made, it will be as efficient as any other portion of the cable, and
will be completely watertight. There are a number of cable splicing kits available today –
epoxy filled, rubber-sealed and so on. Many perform well if the manufacturer’s directions
are followed carefully. If one of these kits is not used, we recommend the following
method for splicing the motor cable.
Examine the motor cable and drop cable carefully for damage. Cut the motor leads
off in a staggered manner. Cut the ends of the drop cable so that the ends match up
with the motor leads. Be sure to match the colors. Strip back and trim off one-half inch
of insulation from each lead, making sure to scrape the wire bare to obtain a good
connection. Be careful not to damage the copper conductor when stripping off the
insulation. Insert a properly sized Sta-kon-type connector on each pair of leads, again
making sure that colors are matched. Using Sta-kon crimping pliers, indent the lugs. Be
sure to squeeze down hard on the pliers, particularly when using large cable. Form a
piece of electrical insulation putty tightly around each Sta-Kon. The putty should overlap
on the insulation of the wire. Use a good quality tape such as #33 Scotch Waterproof
or Plymouth Rubber Company Slipknot Grey. Wrap each wire and joint tightly for a
distance of about 2-1/2 inches on each side of the joint. Make a minimum of four passes
over each joint and overlap each pass approximately one inch to assure a completely
watertight seal.
INSTALLATION PROCEDURES
1. Attach the Pump to the Motor
When attaching the pump to the motor we recommend the pump be bolted down in a
cross pattern around the four bolts. Starting from the back (opposite the cable opening)
and using a cross pattern, tighten the motor bolts to 13.5 ft-lbs, using progressive
tightening until torque is met. (See figure 1 for example).
