How to Wire Red Jacket Pumps for Shallow Wells With 220 Volts

A Red Jacket shallow-water pump with a 230 volt nameplate operates with a power source between 210 and 250 volts, and a Red Jacket shallow-water pump with a 208 volt nameplate works with a power source between 188 and 228 volts.

These voltage ranges let the pump motor accept an electric utility's standard voltage deviation. A pressure switch on the pump motor assembly controls the motor's running time. Wires from the power source connect to the motor at the pressure switch.

Turn off the circuit breaker controlling the Red Jacket shallow water pump. The correct circuit breaker often mounts to the main circuit breaker panel and has a "Well'" or "Pump" label.

Remove the screw covering the Red Jacket pump motor's pressure switch, the gray box attached to the side of the pump motor's housing, with a 1/4-inch hex-head screwdriver. Slide the cover off the motor's switch.

Examine and understand the Red Jacket pump motor's wiring terminals. The pressure switch has four terminals. The two terminals in the center connect to the motor's wires, and the wires from the circuit breaker connect to the outer terminals. A green screw penetrates the bottom of the switch's housing.

Loosen the pressure switch's wire terminals and green screw with a Phillips screwdriver. Do not remove the screws.

Route the ground wire from the circuit breaker around the pressure switch terminals to the green screw. Wrap the ground wire around the green screw and tighten the screw with the screwdriver. The ground wire has either green insulation or no insulation at all.

Insert the black wire from the circuit breaker into the pressure switch's left terminal, the terminal closest to the pump motor. Tighten the terminal screw with the screwdriver.

Slide the black wire from the Red Jacket pump motor into the wire terminal next to the terminal holding the black wire from the circuit breaker. Tighten the terminal screw with a Phillips screwdriver.

Slip the white wire from the circuit breaker into the pressure switch's right terminal, the terminal farthest from the pump motor. Tighten the terminal screw with the Phillips screwdriver.

Place the white wire from the Red Jacket pump motor into the remaining pressure switch terminal. Tighten the terminal screw with the Phillips screwdriver.

Replace the pressure switch's cover before turning on the power to the Red Jacket shallow-well pump.
