| Step 1 |
|
Measure the voltage on the wires going to your pool pump. This voltage will be either 230-240V or 115-120V. Pump manufacturers commonly list these as 230V or 115V. Generally you will have three wires coming to your pump. For 230V you will generally have a red, a black and a green wire. The red and black wires are both hot. There is no neutral. The green wire is always ground. For 115V the three wires are generally black (hot), white (neutral) and green (ground).

|
| Step 2 |
|
CAUTION: Before you start wiring your pump, turn off all power to the pump at the breaker box.
|
|
| Step 3 |
Unscrew the two screws that hold the cover over the back end of the motor. Remove the cover to expose the electrical connectors.
|
|
| Step 4 |
Screw a metal elbow onto your pump at the end of the motor.
|
|
| Step 5 |
Run conduit from the metal box to the pump. String your three wires thru the conduit and metal elbow into the end of the motor. Screw the conduit collar onto the end of the elbow. Ensure that your wire size is adequate for the HP rating and distance from the power source. Check your pump owners manual for the correct size. Wire sizes generally run 14 AWG for motors up to 1 HP and from 14 AWG to 10AWG for larger motors depending on HP and Voltage.

| Step 6 |
If you are wiring for 230V, the three wires coming to the pump from the circuit box are red, black and green. In this example for Hayward pumps, red will go to the L1 terminal and black will go to the L2 terminal. The green wire will be under the green screw to the far right. In addition there is a black plug with two wires coming from inside the motor , a black wire and white wire with a black tracer line. The black plug is positioned so that the white arrow on top of the 2 prong black plug is pointing at 230V.
|
|
| Step 7 |
For clarification this picture shows the terminals without the wires. The red wire is attached to terminal 1 of Line 1 (L1). The black wire is attached to terminal 3 of Line 2 (L2). The green wire is attached to Ground (GND). The black plug is positioned so that the black wire is attached to terminal 5. For 230V the white wire is not attached.
|
|
| Step 8 |
|
If you are wiring for 115V, the three wires to the pump will be black, white and green. Attach the white wire to terminal 1 of Line 1 (L1). Attach the black wire to terminal 3 of Line 2 (L2). Attach the green wire under the Ground screw (GND). The black plug is shifted in position so the the black wire is attached to terminal 4 Line 2 (L2) and the white wire is attached to terminal 5. Note: in this position the white arrow on top of the 2 prong black plug is pointing at the 115V label.
|
|
| Step 9 |
|
Replace the motor cover and secure it with the two screws.
|
|
| Step 10 |
Lastly your pump motor must be bonded in accordance with local electrical code requirements. Use a solid copper conductor, size 8 AWG or larger. Run this wire from from a reinforcing rod to the pressure wire connector provided on the motor housing. Note: In this example the wire coming from the bottom of the picture is going to the pump. The upper wire is going to the heater to bond the heater.

 Tips & Warnings
|
- Make sure that your pump is connected to a GFCI circuit.
- Make sure all power to the pump is turned off at the circuit breaker before wiring the pump.
- If your are unfamiliar with local electrical codes and regulations have a licensed electrician check your wiring.
