A common three-phase SPD wiring diagram includes L1, L2, L3, N and PE. The SPD earth terminal should be connected to the PE bar with a short and direct conductor. TN-S systems commonly use 4P or 4+0. A TN-S earthing system runs separate neutral (N) and protective earth (PE) conductors from the source transformer to every point in the installation — nothing combined, no shared PEN conductor. However, if the incoming supplies are at 11kV and the transformers are in the ownership of the user, the LV supplies may be earthed in a less conventional way using a high.
