Install a PE (protective earthing) conductor that is identical in size, insulation
material, and thickness to the branch-circuit supply conductors. The PE conductor
insulation must be green with yellow stripes. The earthing conductor is to be
connected from the unit to the building installation earth or, if supplied by a
separately derived system, at the supply transformer or motor-generator set
grounding point.
