And here's a much more complete explanation: http://www.schneider-electric.ca/www/en/products/stab-lok/Gen_Panels_Appl_Note_EN.pdf
All the usual ways to do it incorrectly and some that are correct - plus you'll understand the pros and cons of each method

That's odd, now that you mention it- I'd think it would be the other way around, as PME & shared earth/neutral is illegal in the US but more prevalent in Europe.
Do you mean PME as in the British sense (Protective Multiple Earthing) ?

It would still be against our "code" to have a shared neutral/earth at any point on the customer's side of the main service equipment (including any multiple bonding on a generator which would result in neutral current being shared on a protective grounding conductor).

The multiple-earthing aspect of PME applies only to the distribution side of the network here, the last point at which at parallel earth can be applied being at the service entrance to the premises.

Continental Europe is another story.

Paulak, are you saying that USA we can't share the neutral? How do I get a neutral for the loads that will be on the generator? Is the neutral coming from the generator? I don't know if that is the correct way of puting that. Do I seperate the neutrals in the subpanel?
