What Are the Basics of Swimming Pool Wiring?


Quick Answer

The basics of swimming pool wiring include knowing the voltage from the house circuit to the pump; ensuring that the electrical supply is compatible with the pump's motor, phase and cycle; having all electrical wiring conform to local codes and National Electric Code regulations and wiring the pump using the pump's wiring diagram and related instructions as a guideline. Failure to properly wire a swimming pool is dangerous and may void the warranty. Owners are advised to seek assistance from a professional electrician.

Measure the voltage of the circuit to the pool pump using a multimeter. Before continuing, disengage electricity at the breaker box and unscrew the cover on the back of the motor, exposing the motor's wiring. Install a metal elbow onto the pool pump and run conduit from the metal box to the pump. Screw the end of the conduit onto the elbow, running the three wires through the conduit and elbow to the motor. Consult a professional or the pump's manual to ensure the wiring is adequate for the motor's size.

One of the basics for wiring is to know the color codes of the wiring. Generally, the wires are red, black and green. The red wire will run to terminal one and the black to terminal two. The green wire will be under the green screw to the right. The wiring configuration varies depending on the motor's voltage.

Once the wiring is installed, reattach the motor cover and bond in accordance with code requirements.
