A new dwelling requires a grade A category LD2 system. The main intake is typical of domestic arrangement being provided in a flush mounted cabinet in an external wall. The consumer unit is 20m away in a cupboard in the main entrance hall.
Where should the supply for the CIE be taken from? My reading of both 5839-1 and 6 is that it should be at or near the origin of the supply. Given, the questions over metal consumer units located outside, is some kind of variation appropriate?
