Beginning of the summer tested ten houses for a housing association on a five year old estate. Eight out of the ten had open continuity faults on at least one conductor on the kitchen ring final circuit. Back to do remedials, first house found in 30 odd minutes at the four gang control grid. All bar one of the others at the same point. Half a day I had resolved all eight. Bad design? or the whole MK grid unit totally inadequate for a ring final using 2.5 solid conductors. Admittedly the links could have been stranded 2.5 but nevertheless.
I'm inclined to agree! I'm probably being naive, but wouldn't the customer have noticed if any of the conductors (apart from earth) was open ? I mean their fridge wouldn't be working....
Also, are you giving me a hint that using 2.5 stranded for the links between each switch might make it slightly easier?
