No such thing as 220v or 230v, only 240v; which some people insist on
calling almost anything. However, you are thinking of 208v, which is two
legs of three phase; but since you don't have 3 phase, it really doesn't
matter.


What voltage is 208 using two out of three legs of ? It is usually a 208
three phase system. YOu take two legs off that and get the nominal 110
volts. Not to get hung up on what to call it but whenever I hear
110,115,120 and not often but sometimes 125 volts mentioned I think of it as
the voltages the normal outlets in the home have been called over the years.
Same as for the 220 to 240 volts. But I don't think that the 208 has ever
been mentioned except as a 3 phase circuit and is not found in normal
residential service.


Try again. Two legs of three phase 208 give you one phase 208. Any
single leg to the grounded current carrying conductor (neutral) gives
you 120 volts. 208 is found in normal residential service in multiple
dwellings and in single family detached homes that are located in
neighborhoods dominated by commercial occupancies or served by the same
transformer set as a larger multiple dwelling. Supply practices vary by
utility, state, dominant loads in area... A single phase appliance
rated for 230/208 supply will run on any single phase voltage between
205 and 245. With some such appliances you will have to change the
motor taps in the stuffing box on the motor to allow it to run on the
lower voltage. 230 is the nominal voltage that identifies equipment
that will run on voltages between 220 and 240. If the equipment is not
marked with the /208 it will not run on the lower voltage without a real
risk of overheating and motor failure.
