All you do is wire the float switch into one of the 220v legs. So pick one and wire the line 220v to one side of the float switch, then the other side of the float goes to the pump.

Is it OK to run 1 leg of the 220 800' feet through #12 wire? I think it would be better if you can recommend a contactor or relay that could go between the float switch and the leg of the 220v line to the pump. Can you recommend a specific relay or contactor. I was always told to keep the load on the 2 legs of a 220 equal. What can happen if one leg looses all that juice by going back and forth to the float switch.
Plus to go that distance I would need # XXXXX wire...which is very pricy.
What is the amperage of the motor itself.. Full load amps..

HI Glenn:

It turns out its 543 feet from the pump-house to the tank. Will that be ok for the one leg of the 220v line to the float & back to the pump on #14 wire?

ARE YOU CERTAIN THAT THIS SET UP WILL NOT DAMAGE THE 1/2 hp 5amp pump or controls?

Thanks, Bruce
Here is what you need to do. Go to your local supply house. Get a 20amp rated 220v general purpose contactor with a 120v coil on it. Then put that in the circuit at the pump. If you need a wiring diagram of how to set this up - let me know and Ill be more then happy to make one up for you.
