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 180.degree. out of phase with each other or a 208V three phase system which has two phases that are only 120.degree. out of phase. In particular, the cooktop includes a system for distinguishing whether the multiple phases of the external power source are 180.degree. out of phase such that the electric resistance heater is compensated against whether it is connected to a three phase external power supply.
