Generator earthing

Hi


I have a tractor driven Backup generator to install on a farm shortly and have a query regarding the earth spike. Does it need to go directly back to the MET or can I connect it directly into the generator earth terminal, the latter being Quite a lot simpler   In my case? 


thanks

  • David,


    Perhaps there is a clue here, in the third post in the thread:

     
    The farm is 200a single phase TN-S and as such does not have an earth spike.




    Which could be a "private transformer" but is perhaps unlikely to be ... in this particular case, it doesn't matter whether the supply is "true TN-S", or "was TN-S but now repaired in places with CNE cable".
