CABLE JOINING
Splicing the Submersible Pump Cable onto the Motor
Waterboy submersible pump motors are a brushless, oil filled motor and require no earth cable. The
motor leads are marked 1,2,3 and need to be connected at the controller in this order, make note of
which number is spliced onto which wire before completing the splice.
Use only industry approved submersible power cable with a recommended conductor size of 4mm²
or larger.
An appropriate waterproof cable splice (jointing) kit includes crimp connectors to join the copper
wires, adhesive heat-shrink tubing, and instructions.
Always ensure the connectors are firmly crimped onto the electrical wire and no insulation is caught
inside.
Allow at least 10 – 15 minutes before moving the join to ensure the heat shrink is set hard.
Splicing the Submersible Cable onto the Low Water Probe
The low water probe is spliced onto the submersible cable in the same manner as the power cable.
The low water probe is a normally closed (NC) switch with no operating polarity, there is no need to
keep track of the wire colors or apply labels.
