Title: Nominal voltage identification system for electric resistance

Abstract: U.S. Ser. No. 2002009312A cooking appliance having an electric resistance heater is connected to a multiple phase external power source and includes a system for compensating for whether the cooktop is connected to 240V split phase system wherein the two phases are out of phase with each other or a 208V three phase system which has two phases that are only out of phase. In particular, the cooktop includes a system for distinguishing whether the multiple phases of the external power source are out of phase such that the electric resistance heater is compensated against whether it is connected to a three phase external power supply.
