L. Abbreviation for English "live wire "= live wire; (also:"line conductor "= current conductor).
PE Abbreviation for English "protective earth "= protective earth, grounding, protective conductor.
PEN Abbreviation for English "protective earth nneutral "= protective conductor neutral.

b) neutral conductor N (blue) on

c) protective conductor PE (green-yellow)

The protective conductor must always be longer than the other conductors, so that in the event of an excessive pull it is the last to leave and can still perform its protective function.

 N Normal line that complies with VDE regulations.
 Y Insulating material consists of plastic on a PVC basis
 M. Sheathed cable.
 - J. The power line is provided with a green-yellow protective conductor.
3 x 1.5 mm² Power line contains 3 wires with a cross-section of 1.5 mm² each.

N Normal line that complies with VDE regulations.
Y Insulating material consists of plastic on a PVC basis
 I. Laying of plaster.
