Current-using equipment: electrical equipment intended to convert electrical energy into another form of energy [SOURCE: IEC 60050-826:2004, 826-16-02, modified].
Let’s refer to the book , in which Y.V. Kharechko gives examples of current-using equipments:
« Current-using equipments is the predominant part of electrical equipment, which is used to convert electrical energy into mechanical, thermal, light and other types of energy. As an example, current-using equipments include such electrical equipment as electric motors, electric heaters, electric lamps, the vast majority of household electrical equipment: electric stoves, hair dryers, irons, washing machines, vacuum cleaners, refrigerators, etc. »
Also in the book  you can find examples of electrical equipment that cannot be current-using equipments :
« Generators, power characteristic converters (e.g. frequency converters), transformers, clamps, plugs, busbars, protective devices, measuring instruments, switchgear and generally cable products are not current-using equipment because they are used to generate, modify, transmit and distribute electrical energy, not to convert it to another form of energy. »
