I'm not sure about the elim. Usually when you have a 220v supply with only 3 wires, you have 2 110v wires and one ground wire. The reason this can work is that the two 110v legs are out of phase with each other and so they add.....in a push pull kind of reaction. In this case a neutral wire is not necessary. The neutral wire in other 220volt setups is actually carrying current from both legs of the 220v. to provide current flow. Since the current flow in a three wire setup is from one 110volt leg to the other 110volt leg a neutral is not needed(as I said redundantly before). The third wire of course is a ground for safety in case a hot wire gets loose and touches the frame of whatever its in. So to use only one leg of 110v from a 3 wire setup would require the addition of a neutral wire to carry the current. The safety ground wire is never to be used for carrying current. Luckily the Power pro has the 4 wire outlet.
