This is the 3-pronged 220 volt cord connected to this dryer:

I think, IIRC, two of the prongs are 120 volt hot wires, 120 degrees


out of phase (that's the 220 volts); while the third, I think, is a


neutral wire.




180 degrees, but technically, no. It's opposite sign, not 180 degrees

out of phase. ...and it should be 240V (twice 120V).



Nonsense. 180 deg out of phase and opposite sign are
the same thing. Hook up a scope and you'll see.


Wrong. I thought you were an engineer.
