An active part is an electrically conductive part, which is intended in normal operation under tension to stand. An active part does not necessarily have to pose a risk of electric shock. Parts with this risk are called dangerous active parts . According to VDE 0140-1, dangerous active parts must not be touchable and touchable conductive parts must not become dangerous active parts even under single fault conditions.
The active parts also include the following electrical conductors:

External conductors and neutral conductors are referred to as active conductors . Furthermore, these conductors are also intended to carry an electrical current in normal operation .

This does not include the PEN conductor , the PEM conductor and the PEL conductor , as they also have a protective function, as well as the PE conductor (protective conductor), which has a pure protective function.
