Fixed diesel generator earthing

D4G
Hi folks, i'm after your knowledge again!


I have a 184KW diesel generator which is to supply a test bay for testing machines to big for the building supply.  The generated supply will not be used/connected to the building supply.

Would the earthing arrangements be as TT with a rod at the generator connected to the neutral/star connection?


Thanks in advance ?

    Yes. BS 7430 says an electrode with an earth resistance of 20 ohms or less.


    Make sure the star point neutral is connected to the frame and the earth electrode.
