We were talking about 220 not 110. Here is the original message:

(Comments, electrical types?) What you say is right for 110. 220 is 110 on one leg, and the opposite polarity of 110 on the other leg. So what you are saying is correct for one leg of 220 and the other connected to ground. But eerything has to be doubled for 220 hot to hot.
