Pool pumps are wired to run on either 230V or 115V. Most are run on 230V and are preset at the manufacturers at 230V. If you are going to wire your own pool pump, you must first know what voltage is coming to your pump from the house circuit breaker. Also you must ensure that the electrical supply agrees with the motor's voltage, phase, and cycle and that all electrical wiring conforms to local codes and NEC regulations. If you are unsure of this voltage or are unfamiliar with electrical codes and regulations, have a professional electrician wire your pump for you or at least check your work. Failure to wire the pump correctly can cause electrical shock or can damage your pump motor and void your warranty.


Step by Step


Step 1

CAUTION: Before you start wiring your pool pump, turn off all power to the pump at the breaker box.

Step 2

The motor arrives from the factory set on 230v and needs to be changed to 115v. There is a toggle switch located at the back of the motor.

Remove the single screw and the toggle switch cover.

Step 3

Press the toggle switch down underneath the 115v designation.

Step 4

Place the toggle switch cover back over the toggle switch and tighten the screw.

Step 5

Using a 1/4 socket, loosen the two screws from the plastic black cap at the back of the motor and move the cap to the side. Do not disconnect the wires connected to the cap.

Step 6

Feed the 3 external wires through the conduit hole. Typically, the 3 external lines will be black, white and green. These represent the hot line, neutral line and ground respectively.

Step 7

Connect the black (hot) line to terminal 1.

Step 8

Connect the white (neutral) line to terminal 3.

Step 9

Connect the green (ground) line to the copper screw with initials GRD molded next to it.

Step 10

Replace the motor cap and tighten screws

Step 11

Attach the bonding wire to the motor's bonding lug. The bonding wire will either be exposed copper or a copper wire with a green sleeve.

Step 12

Finally, prime the pump and turn on the power at the breaker.

You took care of my anxiety. I was ready to return the pump not knowing of the 115 volt switch in rear of pump. No such instructions came with pump. I installed it and was not working. Your video instructions was so so helpful. I really appreciate this.??????????
