Figure 4-1 TN system
A TN system transfers the PE protective conductor to the installed plant or system using a cable.
Generally, in a TN system the neutral point is grounded. There are versions of a TN system with
a grounded line conductor, e.g. with grounded L1.
The TN system can transfer the neutral conductor N and the PE protective conductor either
separately or combined.
