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
