If I am not mistaken, this falls under alternative load Earth/Neutral bonding wiring.

One or 2 photos. ( man of my word )
Floating earth
With earthspike. 3 lights.
My earth/neutral bridge ( yellow lugs )
Testing in kitchen with genny.
We modified 2 genny's today. The one was the Ryobi 6900 and the other was a Fragram 5 GFD-3 5kva.
Tips. The wiring coming from the stator are not wired the same in these 2 models, so you need to make sure which one is being used for the neutral by removing the control panel in front.
I will carry on checking different gennys, but it seems to me that anything 5kva or bigger is not vov, but one still needs to confirm.

That is great ! Thank you for the pics. Nice to learn a bit more on the genny side.
Having a thought (can be dangerous when i have a thought haha)
Instead of opening up the stator and doing what you have done , could it be possible to take the output of the genny and then bond the Neutral and the Earth to the earth spike ?
Now there are the gennys that have the centre tap and some not so not sure if it will work for both.
In my opinion it will work bar maybe the centre tap earth, but I would have to experiment unless a wise person on here knows.
Why I am having this thought is just for warranty stuff as opening the stator may void warranties and all.

Bridging the neutral and earth will work on a vov wound, BUT the centre tap must first be disconnected otherwise you are basically shorting out one half of the stator coil and the genny wont last long at all.

Ah yes of course, Thank you !
So in the end it would have to be opened anyway to verify. Either way really enjoyed this post.

Dont need to open to confirm. Just run the genny and check voltages with meter. Vov will give 115 between neutral and earth and 115 between live and earth, a 50/50 split, then you know its vov.
Peace out .. Derek.
Ah yes true to that too, that is the first test I would do anyway prior to opening. Either way the customer will be informed of what would need to happen and get permission if opening up is required.

The solution is simple ... signage and awareness ... you cant do any more that that.
I install the generator plug point at the meter use the correct equipment (correct size wiring ... circuit breakers ... changeover switch ... IP 65/7 enclosures and lable label and label) then attach a note to the email with the relevant information with regards to V-O-V ... max generator size for the applications and wait for my payment notice.
