Pool pumps are wired to run on either 230V or 115V. Most are run on 230V and are preset at the manufacturer's 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

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 3

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

We recommend adding to connectors (pictured) to the ends of your wires. This will make it easier to make the connections at the terminals.

Step 4

Connect the black (hot) line to terminal 1.

Step 5

Connect the red (hot) line to terminal 3.

Step 6

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

Step 7

Replace the motor cap and tighten screws.

Step 8

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

Step 9

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

Hello Bob - When wiring on 230v, it does not matter which "hot" line goes to L1 and L2. The motor will work as long as one hot line goes to each.

Got the diagram. Your instructions on the phone seem to be that it doesn't matter which wire goes on L1 and L2. The link you sent seems to maybe not be helpful since it doesn't look like what I have before me in the new motor. We'll see, eh?
