Type of earth connection
TN-S Neutral conductor (N) and protective earth (PE) are routed separately in the entire system.
TN-C Neutral conductor (N) and protective earth (PE) are consolidated in a single conductor, the PEN
conductor, in the entire system
TN-C-S In the distribution network, the neutral conductor (N) and the protective earth (PE) are combined (PEN
conductor) and separated in the consumption system.
TT With the TT network, the star point of the transformer and the bodies of the equipment are directly
earthed. The protective earth is thus not in contact with the neutral conductor.
IT The IT network does not have a direct connection between active conductors and earthed parts; the
bodies of the electrical system are earthed.
