Scope: Throughout the Supplement, when reference is made to requirements in “this Standard,” the reference is to requirements in the main body of the Standard and not to other requirements of the Supplement. These requirements provide alternate requirements for the investigation of electronic controls and other circuits used in appliances covered by this standard. Thermal motor protectors in direct contact with motor windings and intended for direct control of the motor supply are outside the scope of this Supplement even if they incorporate one or more electronic components.
