3 Phase and Single-Phase

This is also incorrect you are not charged by how many amps are drawn but by how much power. A 100w light bulb still draws 100w if its powered by 120v or 600v and will still use 100w/h every hour its on.  The advantage to higher voltages is that there is less amps drawn and therefor require a smaller wire(but thicker insulation) and copper is much more expensive than the plastic or silicon insulation.  Most electrical stuff is done with economics in mind.

Yeah, slip of the mind...what I get for typing so late at night...I meant that the wiring is cheaper for higher voltage (Though you then have to pay for a transformer / more expensive high voltage panels, disconnects, meter bases, etc). I think I was mixing up the lower power bill with three phase vs traditional single phase power equipment.
