TN diagram
Distribution diagram that has a point directly connected to ground and the
conductive parts of the installation are connected to this point through
ground protection conductors. This type of mains admits loads between one
or several phases and the neuter.
There are three kinds of TN diagrams depending on the relative position of
the neuter wire (N) and the protection wire (PE):
TN-S diagram
where the neuter wire (N) and the protection wire (PE)
are different in the entire diagram.
TN-C-S diagram
where the neuter and protection functions are
combined in a single wire (PEN) in part of the diagram.
TN-C diagram
where the neuter and protection functions are combined
in a single wire (PEN) in the entire diagram.
