    You should use a double pole breaker.

      You need to post this on the ELEC. forum . And We don't have the pump Specs. Thanks
      I can build anything You want , if you draw a picture of it , on the back of a big enough check .

        But it's a pump and the pool has water in it so it is a plumbing issue right

            Re: breakers

            first how does the breaker work,

            A GFCI is much more subtle. When you look at a normal 120-volt outlet in the United States, there are two vertical slots and then a round hole centered below them. The left slot is slightly larger than the right. The left slot is called "neutral," the right slot is called "hot" and the hole below them is called "ground." If an appliance is working properly, all electricity that the appliance uses will flow from hot to neutral. A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second. http://home.howstuffworks.com/question117.htm
            so if you use two 120 volt breakers that is monitoring the flow of current from the hot to the neutral and since it is 240, there should not be any current flowing on the neutral wire, it will trip, as it indicates that the current is leaking off some where, you will need on designed for 240 volt operation to work properly.


            a basic wiring diagram of a 220 volt spa GFCI

            FOLLOW THE DIGRAM THAT COMES WITH THE BREAKER YOU BUY.

            IF you have any confusion get a qualified person in to do the wiring.

              A very correct answer. You really should just get a 2 pole GFCI breaker of proper specs.
