No disrepect meant but you sound more like a tutor than a onsite electrician, i didn't challange your post nor did i say Earth is required or not just explaining our set-up to a non UK poster....
May i enquire what your field is in electrics (theory or practical) as your posting IMHO give you a theorist angle.
Im also aware of ground resistances too but its all down to local conditions and even 40ohms will give a return circuit rather than a floating neutral which is alot safer and less destructive to any connected load.
Thanks for the lessons in factors etc but after 25yrs in the job i hope im fluent in all the supplied info you've expressed.
(Again a humorous comment no dig intended)
