We have just returned from a VERY wet weekend. The site we were on flooded. We had electric hook up. However Sunday afternoon, first my wife and then my Labrador and me got shocks off of the caravan. Not static shocks, full blown muscle clenching shocks. I unplugged my cable as I thought water may have got into it .That night at about 11 the electric post we were plugged into caught fire. The site manager could not locate a CO2 or dry powder cylinder so we used our own but with the power still on it stayed alight. Finally the power got switched off and we extinguished the fire. Since then one of my motor mover motors has failed, my water pump stopped and smelt of burning, and got roasting hot and my Truamatic hot water won’t fire on gas. Is this just coincidence or has this been caused by passing 200v through the chassis to ground (we measured it by voltmeter at my steps on the wet grass to door frame). Should health and safety be informed and if the above is the effect of the site short what can I do about it, obviously the site hasn’t got a robust, safe, electrical system, RCD’s etc let alone suitable fire fighting equipment.
