Hi guys after a bit of advice. On a new build house, quite big has a 3 phase board. Customer now wants a summer house at the bottom of the garden about 10 meters from the house. Would this need to be converted to a TT system ? Supply is pme. The building is all wood. Thank you, couldn't remember all details on exporting pme outside. Thank you again
Yes, I think I would agree that if the neutral is "chopped through" it is likely outside the control of the DNO. Mind you, I am not sure how that might happen.
If the neutral is lost and injury did occur, it would have to be proven that the DNO took all reasonable precautions to avoid such an occurrence (Reg 7 ESQCR). If it was proven that they failed to do so, then a heavy fine might help them focus.
OED (with apologies to those who are not English 
): "indefinitely" = "To an indefinite amount or extent; without specified or assignable limit or end; unlimitedly."
So the pyramids (Egypt, not Glastonbury) were probably intended to be permanent. On the other hand, "indefinite leave to remain" is clearly limited, though one's corpse could be interred here. That is until some archaeologist starts digging.
