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?

    If the supply is TT with 2 wires and individual rods at each van, then there is not that much of a risk. to get a high touch voltage on anything other than a van with a fault anyway.

    If the earthing is shared then it is more complex but you would still need a broken neutral to give neutral lift, and an NE fault as well.

    TNS I;d not worry.

    Is the trafo on site ?
