1.2.15 Neutral-Protective Conductor (PEN)
The PEN conductor combines the functions of both a protective con-
ductor and a neutral conductor.

1.2.16 Protective Bonding Conductor
Conductorprovidedforprotective-equipotentialbonding.Itspurpose
is to guarantee the same potential between metal parts possibly at dan-
gerous different potential upon fault. It is also referred to as bonding
jumper.

1.2.17 Protective Conductor (PE)
Conductor provided for the purpose of safety against electric shock.
Its function is to safely drain the ground-fault current to the source. It
is also referred to as equipment grounding conductor.

1.2.18 Remote or Zero Potential
Potential of a point conventionally assumed as at the infinite (see
Fig. 1.3 for symbol).
