isolated or switched.
In TN-C-S and TN-S systems, the neutral conductor need not be isolated or switched if the
supply network operator declares that either the PEN or the N conductor of the supply is
reliably connected to earth by a suitably low resistance.
NOTE 1 This low resistance may be verified by measurement of the resistance of the earth electrode in
accordance with clause 612.
NOTE 2 The neutral conductor is not recognized as being reliably connected to earth by a suitable low resistance
in Belgium, France, Norway, Portugal, Spain and Switzerland.
