Electrical Connections
Risk of severe injury or death by electrical shock, or damage to system.
• Always disconnect the electrical power before touching the pump.
• A ground fault circuit interrupter (GFCI) is required.
• If the power cord is damaged, it must only be replaced by qualified personnel.
Employ a licensed electrician or water systems contractor to ensure installation is done properly. Follow
cable splicing kit instructions.
1. Make sure the supply voltage and current ratings correspond with the electrical ratings of the motor
and control box.
2. Install a fused disconnect switch or circuit breaker.
3. Ground the pump and the distribution panel with the motor's green conductor.
4. For two-wire pumps, make wiring connections.
5. For three-wire, single-phase pumps,
make wiring connections.
• Install a magnetic contactor if the
pressure switch is not sufficient to
handle the motor's electrical rating.
The pressure switch is then used as a
pilot circuit to control the contactor.
6. For three-wire, single-phase pumps,
install control boxes in accordance to
the control box's manual and the elec-
trical code.
• Mount control boxes in an area pro-
tected from rain, snow, high tem-
peratures, and temperatures below
14 °F (-10 °C).
7. For 3-phase pumps, install a magnetic
starter equipped with quick-trip, ambi-
ent compensated heaters, electronic
adjustable overload, soft start, or VFD
of correct horsepower size.
8. For 3-phase motors, install a separate
lightning arrestor close to the wellhead.
9. Test the unit. Brace pump shell and
apply power momentarily.
10. For three phase motors, ensure pump
rotation is counterclockwise when
viewed from pump discharge.
• Interchange any two leads at the
magnetic starter to change rotation.
11. Place the motor and pump labels in the
circuit breaker box for future reference.
