Abstract:
    An error prevention device for electrical devices, such as breakers and differential switches, comprises a certain number of pins provided on a first device housing, wherein each pin is corresponding to a characteristic need to be considered during cooperation, a same number of holes provided on the housing of another device, wherein the holes are sealed by jamming members which is exposed when being detached. Positions of the pins face to the holes at a combination postio of the two devices, the pins corresponding to a non-validated characteristic of the first device are removed, the jamming members in the holes corresponding to a validated characteristic of the second device are detached, thereby, the pins which are not removed on the first device can be inserted into the corresponding holes on the second device.
