Dear Sir: I know that 3 wires come into my house, a +120 volt, a -120 volt, both 180 degrees out of phase, and a neutral wire. One +120v wire and one -120v wire attach to the water heater that requires 220 volts. The neutral wire is not attached. A protective ground wire is attached. My question is how do two live, hot electrical wires form a circuit, that is necessary for moving energy through the heater coils and through the watt meter? Please explain the necessary "circular" path of the energy flow. Many thanks, Bob
