I am not 100% sure about this but I believe the neutral of UK mains is connected to earth at the substation. I think you are ight, the majority of systems here are, unless AFAIK you are supplied by an overhead cable. At the station, one leg of the transformer is bonded to the station earth, so there neutral and earth are at the same potential, they are not though anywhere else. http://www.schneider-electric.com/cahier_te...ect172.pdf Seems to cover what we are talking about.
