A 230 volt motor will run on 208 volts if it is a standard modern motor. You will have a problem if: Your power supply is poor part of the year - some power companies deliver only 185 volts on hot summer days - in that case your motor will either burn up or shut off depending on the quality of your motor protection - In any case your 230 volt motor should never be run at full load on a 208 volt supply - it will overheat and have a short service life The solution is to buy a special motor that is rated for 208 volt service - as there is little 208 volt in NORTH AMERICA you may have to search but they are available and work well.
