We did some work many years ago at a farm, being converted into a religious college , we found one ring main with 10 spurs , of those
10 spurs several had spurs themselves . Eventually we counted 30 double sockets on the whole circuit , fortunately most were buried behind cabinets and other units and unused, those exposed had 5 gang extension bars plugged into them if only 20 % of them were used to full capacity we reckoned the place would have been ablaze in minutes .
