Double pole RCBOs in caravan site

lyledunn

I have a caravan site of around 150 static vans plus 20 touring pitches. Each caravan is supplied from a group pillar via an individual 30mA RCBO but it is single pole. Non compliant, yes, but if you had to call the risk, where would you place it?

    Thanks Mike. System is TN-S but distribution cables are hundreds of metres with all sorts of dubious connections. Lost the earth somewhere underground at 3 of the pillars so had to TT them. Loss of neutral is the issue but not on the DNO side as tx dedicated and on site.
