The question is the neutral. Does the wiring out to the pool pump provide a
neutral? If not, you really should not do this.

If there is a neutral, you can take a 110 volt socket off the circuit for
low wattage appliances. It is not acceptable to use the ground as a neutral.

Finally, a correct and useful answer.
