Specifically, in a wye configured system, the phase-to-neutral voltage is equal to the phase-to-phase voltage divided by the square root of three, or 208V / 1.73 = 120V. Thus, the phase-to-phase voltage must be 208V in order to get 120V from the system.
Quick Answer. A person who likes pain is called a masochist. Masochists enjoy situations that the majority of people would find painful or unpleasant.
