If you are asking how to wire up a receptacle to run a 240 volt pump, you need to have a box on the roof first of all. You will need a 20 amp double pole breaker for this. You will need to pull 2- hot wires from the breaker box, 1- neutral, and a bare ground wire. Size of wire would be # 12 THHN stranded wire. A total of 4 wires. This would be to code. Or, buy enough Romex wire, #12 with ground wire and red, black, and white in side, tie into the breaker that way. Red and black will be your hot wires to pump, if it has no neutral you can use both the white and bare to ground, very easy to do.I hope this is what you wanted to know. Shastalaker7
