Examples of applications in 230/400 V systems
TN-C systems
Neutral conductor and protective earth conductor functions
are combined throughout the network in a single conductor,
the PEN conductor (4-conductor-system).

TN-C-S systems
Neutral conductor, PEN conductor and equipotential bonding
system are connected once at the main distribution board or after
the incoming supply to the building. Therefore, a TN-C system
becomes a TN-S system (TN-C-S system) from this point onwards.
