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?

    I have encountered one broken neutral on an overhead DNO TT supply to two houses in twenty or so years, the upfront 30 mA RCD was tripping in the house I was called out to and would not reset, the incoming neutral tail was live due to it being back fed from next door, these things do happen and are possibly more likely to happen within the site installation itself.

    I don't know how to call this one,. I would expect to see other double pole isolators and RCDs in place, but how reliable they are is questionable, as if they even exist.
