generator, it is to be ensured that the Neutral of the generator is either bonded internally
to the frame / chassis of the generator or externally to the Earthing Terminal "EG" on
the generator. This will create a Neutral to Earth Ground bond in the generator (Neutral
of generator " frame / chassis of generator " Earthing Terminal "EG" on the generator

that if a ground fault occurs, leakage current is able to return back to the Neutral of
generator winding through the Earth ground path for tripping of the rCD.
For typical Mobile installation (Please refer to Fig. 3.14)
All structural metallic parts of the frame of the motorhome / caravan which are acces-

termed "chassis" and is shown by symbol "
